00:00:02,000 --> 00:00:04,000
[Tommy MacWilliam] [Chuo Kikuu cha Harvard]

3
00:00:04,000 --> 00:00:08,000
[Hii ni CS50.] [CS50.TV]

4
00:00:08,000 --> 00:00:12,000
>> Haki zote, kila mtu, kuwakaribisha kwa iOS: Uandishi Apps kama Boss.

5
00:00:12,000 --> 00:00:16,000
Semina hii ni kwenda kuzingatia kuandika programu kwa iPhone

6
00:00:16,000 --> 00:00:19,000
na kwa upande kuandika programu kwa iPad, na hivyo sisi ni kimsingi ya kwenda kutembea kwa njia ya

7
00:00:19,000 --> 00:00:23,000
wanandoa mbalimbali ya mifano ya jinsi ya kufanya programu, mchezo rahisi kama Tic TAC Toe,

8
00:00:23,000 --> 00:00:26,000
au kama wewe ni zaidi ya nia ya kufanya programu kama aina fulani ya habari msomaji

9
00:00:26,000 --> 00:00:30,000
au kitu ambacho inaingiliana na Internet nami majadiliano kuhusu kuwa vilevile.

10
00:00:30,000 --> 00:00:32,000
Hapa ni ajenda yetu fupi.

11
00:00:32,000 --> 00:00:36,000
>> Programu IOs yameandikwa katika lugha inayoitwa Lengo-C,

12
00:00:36,000 --> 00:00:39,000
na hivyo hii ni kidogo sawa na C lakini si kweli wakati wote,

13
00:00:39,000 --> 00:00:41,000
hivyo tutaweza kuwa na kuzungumza kidogo kuhusu lugha yenyewe

14
00:00:41,000 --> 00:00:45,000
na kisha jinsi ya kujenga Apps iPhone kutumia programu hii ya programu inayoitwa XCode,

15
00:00:45,000 --> 00:00:48,000
ambayo kama si kupakuliwa hivyo bado jisikie huru kuanza shusha sasa.

16
00:00:48,000 --> 00:00:50,000
Ni kadhaa gigabytes.

17
00:00:50,000 --> 00:00:54,000
Ni lazima kuwa huru juu ya Hifadhi App, hivyo itabidi haja ya kuwa na Mac

18
00:00:54,000 --> 00:00:57,000
walau mbio toleo la OS X.

19
00:00:57,000 --> 00:00:59,000
Kama huna, hakuna tatizo.

20
00:00:59,000 --> 00:01:02,000
Tuna Macs katika kituo cha sayansi inapatikana kwa matumizi yako

21
00:01:02,000 --> 00:01:05,000
na XCode imewekwa, na hivyo kujisikia huru kutumia hizo kwa maendeleo.

22
00:01:05,000 --> 00:01:07,000
Kama unataka kufanya App lakini hawana Mac, usijali.

23
00:01:07,000 --> 00:01:09,000
Kuna mengi ya rasilimali ya chuo kwa ajili hiyo.

24
00:01:09,000 --> 00:01:15,000
Na hivyo basi tunakwenda cover 2 mifano kubwa ya programu mbalimbali unaweza kufanya.

25
00:01:15,000 --> 00:01:19,000
Lengo-C ni utaalamu kile kinachoitwa kuweka super ya C.

26
00:01:19,000 --> 00:01:24,000
Hiyo ina maana kwamba yoyote code C pia ni halali Lengo-C code.

27
00:01:24,000 --> 00:01:29,000
Hiyo ina maana kwamba sisi aina ya duct taped juu ya baadhi ya vipengele ziada C.

28
00:01:29,000 --> 00:01:33,000
Baadhi ya makala haya ni pamoja na kutokuwa na milele kuandika malloc tena, kumshukuru Mungu,

29
00:01:33,000 --> 00:01:36,000
hakuna kuwa na wasiwasi kuhusu kuyatumia wale kijinga na kumkomboa yao na mambo ambayo yote

30
00:01:36,000 --> 00:01:40,000
wewe kuchukia kuhusu C, na ni aina ya wamekwenda katika Lengo C-.

31
00:01:40,000 --> 00:01:43,000
>> Sasa, Lengo-C pia ina kiwango kikubwa zaidi maktaba,

32
00:01:43,000 --> 00:01:47,000
hivyo kuna mengi zaidi funktionalitet kupata kwa ajili ya ndani ya bure ya Lengo-C.

33
00:01:47,000 --> 00:01:50,000
Kumbuka wakati tulikuwa kuandika PHP sisi niliona kwamba sisi akaenda kutoka

34
00:01:50,000 --> 00:01:54,000
lugha hii ndogo ya maktaba kubwa ya mambo hayo yote mambo unaweza kufanya.

35
00:01:54,000 --> 00:01:56,000
kitu kimoja kinachotokea katika iOS.

36
00:01:56,000 --> 00:01:59,000
Kuna vitu kwa ajili ya mambo kama kalenda Buddhist, na kwa kweli kitu chochote

37
00:01:59,000 --> 00:02:05,000
unaweza uwezekano kufikiria pengine ipo tayari katika utekelezaji Lengo-C ya.

38
00:02:05,000 --> 00:02:08,000
Lengo la sehemu Lengo-C ni referencing kitu

39
00:02:08,000 --> 00:02:11,000
kuitwa Object-Oriented Programming.

40
00:02:11,000 --> 00:02:14,000
Hii ni aina ya dhana mpya, lakini tumekuwa kweli zaidi ya kujifunza

41
00:02:14,000 --> 00:02:17,000
mengi ya dhana hizi tayari.

42
00:02:17,000 --> 00:02:19,000
Dhana Programming Object-Oriented ni kwamba utaenda kuunda

43
00:02:19,000 --> 00:02:23,000
mengi ya maadili yako karibu mambo haya kuitwa madarasa,

44
00:02:23,000 --> 00:02:26,000
na madarasa haya ni kweli kutukuzwa structs.

45
00:02:26,000 --> 00:02:30,000
Ndani ya struct sisi kimsingi alisema hapa ni kitu,

46
00:02:30,000 --> 00:02:32,000
na jambo hili linaweza kuwa na wanachama.

47
00:02:32,000 --> 00:02:35,000
Kwa mfano, nodi katika orodha wanaohusishwa inaweza kuwa na mambo mengine

48
00:02:35,000 --> 00:02:38,000
kama thamani, pointer nodi ijayo katika orodha,

49
00:02:38,000 --> 00:02:44,000
na pamoja kwamba pointer na kwamba thamani linajumuisha hii mfano mmoja wa struct.

50
00:02:44,000 --> 00:02:47,000
Madarasa ni sawa sana isipokuwa

51
00:02:47,000 --> 00:02:50,000
madarasa wanaweza pia kuwa kazi ndani mwao.

52
00:02:50,000 --> 00:02:54,000
Wakati sisi alitangaza struct, tunaweza kusema tu n int au * nodi ijayo.

53
00:02:54,000 --> 00:02:57,000
>> Sasa na Lengo C-tunaweza kweli kuweka majukumu

54
00:02:57,000 --> 00:02:59,000
ndani ya mambo hayo.

55
00:02:59,000 --> 00:03:03,000
Kitu kingine kwamba unaweza kufanya ni madarasa wanaweza kurithi data kutoka madarasa mengine.

56
00:03:03,000 --> 00:03:07,000
Kwa mfano, tutaweza kuwa na kuangalia rundo la kujengwa katika Lengo-C madarasa.

57
00:03:07,000 --> 00:03:11,000
Mmoja wao inaweza kuwa ya darasa kuwa inawakilisha maoni kwa screen,

58
00:03:11,000 --> 00:03:14,000
na hivyo kwa kusema nataka kutekeleza maoni yangu mwenyewe

59
00:03:14,000 --> 00:03:18,000
sisi kimsingi kusema mtu zaidi ya saa Apple, pengine kweli nice watu,

60
00:03:18,000 --> 00:03:21,000
aliandika darasa hili kwa ajili yangu, na Hushughulikia mambo majishauwo vifungo

61
00:03:21,000 --> 00:03:25,000
au utoaji screen, na sisi itakuwa kweli pained

62
00:03:25,000 --> 00:03:28,000
kutekeleza funktionalitet kwamba wote sisi wenyewe, na hivyo kwa kifupi

63
00:03:28,000 --> 00:03:31,000
kurithi data tunaweza kusema kila kitu kwamba alifanya katika darasa kwamba

64
00:03:31,000 --> 00:03:34,000
Mimi pia nataka ndani ya darasa langu, na kisha mimi naenda kufanya baadhi ya mambo mengine,

65
00:03:34,000 --> 00:03:37,000
yaani kutekeleza programu.

66
00:03:37,000 --> 00:03:40,000
Hiyo ni nini kuwa urithi maana ya neno. Tutaweza kuona mfano halisi zaidi.

67
00:03:40,000 --> 00:03:42,000
>> Na hatimaye, muhimu kwa Programming Object-Oriented ni kwamba

68
00:03:42,000 --> 00:03:45,000
inaongoza kwa encapsulation data.

69
00:03:45,000 --> 00:03:48,000
Katika baadhi ya tatizo letu sisi inaweza kuwa na seti hizi kubwa, vigezo kimataifa

70
00:03:48,000 --> 00:03:51,000
na globals kila mahali, na kwamba ni jinsi gani tunatarajia kuweka wimbo wa taifa.

71
00:03:51,000 --> 00:03:55,000
Pamoja na madarasa tunaweza kuanza encapsulating habari ndani ya kifaa.

72
00:03:55,000 --> 00:03:58,000
Kama tuna moja screen programu yetu, sisi si kweli haja ya kuwa na data yoyote kutoka

73
00:03:58,000 --> 00:04:01,000
mwingine screen katika ndani ya programu yetu ya kwamba,

74
00:04:01,000 --> 00:04:04,000
na hivyo kwa encapsulating mambo ndani ya madarasa kweli hii husababisha

75
00:04:04,000 --> 00:04:08,000
kwa kubuni bora zaidi kificho, na hii inawezekana kwa baadhi ya makala za ziada

76
00:04:08,000 --> 00:04:11,000
Lengo la C-.

77
00:04:11,000 --> 00:04:15,000
Forewarning, syntax kwa Lengo-C ni ndizi.

78
00:04:15,000 --> 00:04:19,000
Ni kama kitu tumekuwa kuona mbele,

79
00:04:19,000 --> 00:04:22,000
hivyo ni kidogo kidogo ya kujifunza Curve kupata kutumika kwa

80
00:04:22,000 --> 00:04:24,000
nini heck maana ya hii?

81
00:04:24,000 --> 00:04:27,000
Lakini mara moja kupata zamani kwamba awali kujifunza Curve ni kweli, kweli laini

82
00:04:27,000 --> 00:04:29,000
kuanza kuandika programu.

83
00:04:29,000 --> 00:04:33,000
>> Kutangaza darasa, kusema hapa ni darasa langu, ipo,

84
00:04:33,000 --> 00:04:35,000
na labda hapa ni baadhi ya mambo ambayo mimi nina kwenda kufafanua baadaye,

85
00:04:35,000 --> 00:04:38,000
Mimi nina kwenda kusema @ interface.

86
00:04:38,000 --> 00:04:41,000
Mimi nina kwenda kusema @ interface. Mimi naenda kukupa darasa langu jina.

87
00:04:41,000 --> 00:04:43,000
Na kisha baadaye mahali pengine mimi nina kwenda kusema @ mwisho,

88
00:04:43,000 --> 00:04:46,000
na kila kitu katika kati interface @ na mwisho @

89
00:04:46,000 --> 00:04:48,000
ni kwenda kuwa darasa langu.

90
00:04:48,000 --> 00:04:51,000
Kwamba ni kwenda kuwa nini ndani ya. Yetu files h.

91
00:04:51,000 --> 00:04:55,000
Tu kama katika C yetu h. Files kimsingi alisema hapa ni baadhi ya mambo ambayo yapo.

92
00:04:55,000 --> 00:04:57,000
Mimi si lazima ninawaambieni wayatendayo bado,

93
00:04:57,000 --> 00:04:59,000
lakini compiler anahitaji kujua kwamba wao kuwepo.

94
00:04:59,000 --> 00:05:04,000
Baadaye ndani ya m wetu. Files-kwa sababu m kwa Lengo-C

95
00:05:04,000 --> 00:05:08,000
ni ambapo sisi ni kweli kwenda kufafanua nini hawa madarasa kufanya.

96
00:05:08,000 --> 00:05:11,000
Kiasi kama. Yetu files c, sisi zinazotolewa utekelezaji kwa ajili ya kazi.

97
00:05:11,000 --> 00:05:15,000
Ndani ya faili wetu. M tunakwenda kusema hapa ni nini wote wa kazi

98
00:05:15,000 --> 00:05:18,000
ndani ya darasa langu-nini wao wote kufanya.

99
00:05:18,000 --> 00:05:22,000
Na hatimaye, ndani ya struct tunaweza kusema ndani ya braces wale curly

100
00:05:22,000 --> 00:05:25,000
int n au nodi * ijayo,

101
00:05:25,000 --> 00:05:28,000
na katika Malengo ya C-tunakwenda kutumia Keyword @ mali,

102
00:05:28,000 --> 00:05:31,000
na hii ni nini kinaendelea kufafanua mali,

103
00:05:31,000 --> 00:05:36,000
au kazi zisizo kuwa ni sehemu ya madarasa yangu.

104
00:05:36,000 --> 00:05:40,000
>> Wito kazi katika Lengo-C ni pia ndizi.

105
00:05:40,000 --> 00:05:43,000
Wakati sisi alitangaza kazi katika C sisi alisema kitu kama int foo

106
00:05:43,000 --> 00:05:46,000
na wazi Paren na kisha akampa orodha ya hoja.

107
00:05:46,000 --> 00:05:51,000
Hii ni nini kutangaza mbinu au utendaji inaonekana kama katika Lengo C-.

108
00:05:51,000 --> 00:05:54,000
Kama mimi nataka kutangaza kazi au njia

109
00:05:54,000 --> 00:05:58,000
ambapo mimi kusema mbinu ni kweli tu kazi hiyo ni mwanachama wa darasa,

110
00:05:58,000 --> 00:06:01,000
hivyo aina ya kubadilishana, lakini si kweli,

111
00:06:01,000 --> 00:06:03,000
hivyo ndani ya njia yangu mimi wanataka kujenga njia mpya.

112
00:06:03,000 --> 00:06:06,000
Ni kwenda na kurudi kitu, hivyo ni kwenda kuwa ya utupu aina.

113
00:06:06,000 --> 00:06:08,000
Hii ni aina ya kurudi kwa kazi yangu.

114
00:06:08,000 --> 00:06:11,000
Sasa tuna parens hapa kwa sababu-sijui.

115
00:06:11,000 --> 00:06:14,000
Next ni kwenda kuwa jina ya kazi yangu,

116
00:06:14,000 --> 00:06:17,000
na kisha hatimaye tuna semicolon tu kama sisi tulikuwa katika C.

117
00:06:17,000 --> 00:06:19,000
Nini mpya hapa ni guy hii hapa.

118
00:06:19,000 --> 00:06:22,000
Hyphen Hii ni kweli ni lazima, na nini hii inasema ni kwamba

119
00:06:22,000 --> 00:06:26,000
njia hii hapa lazima wito kwa mfano wa darasa.

120
00:06:26,000 --> 00:06:29,000
>> Baada ya sisi alitangaza structs yetu sisi pengine alisema kitu kama

121
00:06:29,000 --> 00:06:32,000
struct nodi n, na kwamba aliumba

122
00:06:32,000 --> 00:06:35,000
au instantiated mmoja wa wale structs ili niweze kweli kuanza kufanya kazi

123
00:06:35,000 --> 00:06:38,000
na nini ndani yake, hivyo dash hii ina maana kwamba tuna

124
00:06:38,000 --> 00:06:41,000
instantiate darasa tu like sisi instantiated kwamba struct

125
00:06:41,000 --> 00:06:43,000
kabla tunaweza kuwaita njia hii juu yake.

126
00:06:43,000 --> 00:06:46,000
Kama mimi nataka kuanza kuongeza hoja kwa njia yangu

127
00:06:46,000 --> 00:06:48,000
anapata ndizi hata zaidi.

128
00:06:48,000 --> 00:06:50,000
Hapa ni njia yangu jina.

129
00:06:50,000 --> 00:06:53,000
Kisha mimi naenda kuwa koloni, na baada ya koloni hii inasema hapa inakuja hoja fulani.

130
00:06:53,000 --> 00:06:56,000
Njia hii inachukua moja hoja.

131
00:06:56,000 --> 00:06:59,000
aina ya hoja yake ni int, na jina la hoja kwamba

132
00:06:59,000 --> 00:07:03,000
au variable kwamba mimi nina kwenda kuanza kutumia ndani ya njia ya inaitwa i.

133
00:07:03,000 --> 00:07:05,000
Tena, hii ni mbinu. Inachukua moja hoja.

134
00:07:05,000 --> 00:07:10,000
>> Kama unataka kuanza kuongeza hoja zaidi ni anapata ndizi zaidi

135
00:07:10,000 --> 00:07:13,000
kwa kuwa tuna hii koloni kwamba anasema hapa inakuja orodha yangu ya hoja.

136
00:07:13,000 --> 00:07:15,000
Hoja hii ya kwanza ni integer.

137
00:07:15,000 --> 00:07:17,000
Sasa, hoja hii ya pili ni ya kuvutia.

138
00:07:17,000 --> 00:07:20,000
variable kwamba mimi nina kwenda kuwa na kutumia ndani ya kazi yangu

139
00:07:20,000 --> 00:07:23,000
inaitwa f, hivyo ndani ya kazi yangu mimi naweza kusema

140
00:07:23,000 --> 00:07:25,000
f + = 1 au kitu.

141
00:07:25,000 --> 00:07:30,000
Hii kitu hapa kimsingi ni muhimu kwa kuwa hoja au parameter.

142
00:07:30,000 --> 00:07:34,000
Tu kama sisi alikuwa jozi thamani muhimu na kitu kama JSON au arrays associative

143
00:07:34,000 --> 00:07:37,000
Lengo-C alifanya uamuzi wa kusema, sawa, hivyo tu kwamba ni kweli wazi

144
00:07:37,000 --> 00:07:39,000
wakati wewe piga njia gani vigezo vyote hivi ni

145
00:07:39,000 --> 00:07:41,000
Mimi nina kweli kwenda jina yao yote.

146
00:07:41,000 --> 00:07:45,000
Wakati wewe piga njia, itabidi kweli kusema andFloat,

147
00:07:45,000 --> 00:07:47,000
na kisha utasikia kupita in

148
00:07:47,000 --> 00:07:50,000
>> Inafurahisha, moja hii si jina lake, lakini yote ya vigezo vingine ni,

149
00:07:50,000 --> 00:07:53,000
hivyo kama sisi alikuwa hoja 3 mimi naweza kusema andFloat

150
00:07:53,000 --> 00:07:56,000
na mwingine kuelea na kadhalika.

151
00:07:56,000 --> 00:08:01,000
Wakati mimi kuwaita njia hizi ni ya ndizi shaka,

152
00:08:01,000 --> 00:08:04,000
hivyo kama nina kitu, na mimi defined njia iitwayo foo,

153
00:08:04,000 --> 00:08:09,000
na mimi nataka simu yake, badala ya kusema foo wazi / parens karibu

154
00:08:09,000 --> 00:08:11,000
Mimi naenda kufungua bracket.

155
00:08:11,000 --> 00:08:13,000
Hapa ni jina la njia yangu.

156
00:08:13,000 --> 00:08:17,000
Mimi naenda kuifunga bracket, na hii ni kitu mimi nina wito juu.

157
00:08:17,000 --> 00:08:20,000
Kumbuka, aina ya mbinu hizi zipo ndani ya madarasa

158
00:08:20,000 --> 00:08:23,000
kwa sababu madarasa unaweza kuwa mbinu defined ndani mwao.

159
00:08:23,000 --> 00:08:26,000
>> Hapa nimepata kiholela umba kitu cha darasa baadhi,

160
00:08:26,000 --> 00:08:28,000
na hii ni syntax kwa kufanya hivyo.

161
00:08:28,000 --> 00:08:31,000
Kuna 2 hatua ya kujenga kitu.

162
00:08:31,000 --> 00:08:34,000
Hatua ya kwanza ni kusema nataka kutenga nafasi.

163
00:08:34,000 --> 00:08:37,000
Hii ni sawa malloc. Hatuna kusema malloc tena.

164
00:08:37,000 --> 00:08:42,000
Sisi imeshuka m, alifanya hivyo alloc, na badala c. Kwa. M.

165
00:08:42,000 --> 00:08:47,000
Baada ya sisi kitu alloc sisi basi haja initialize yake.

166
00:08:47,000 --> 00:08:49,000
Kimsingi wakati wewe kuunda vitu unaweza kutaka kuwa na baadhi ya mantiki

167
00:08:49,000 --> 00:08:53,000
kwamba executes wakati wao ni umba, hivyo unaweza kupita katika maadili baadhi default

168
00:08:53,000 --> 00:08:57,000
au kitu kama hicho, na hivyo njia hii init ni nini hasa inajenga kitu.

169
00:08:57,000 --> 00:08:59,000
Sisi kwanza kutenga nafasi, kama tulivyofanya katika C,

170
00:08:59,000 --> 00:09:04,000
na kisha sisi initialize hayo, ambayo wanaweza au kufanya mengi nzima.

171
00:09:04,000 --> 00:09:07,000
Kisha sisi ni kurudi jambo hili katika o kitu.

172
00:09:07,000 --> 00:09:09,000
Kuna nyota hapa kwa sababu hii ni kitaalam pointer,

173
00:09:09,000 --> 00:09:12,000
lakini usijali, kuyatumia ni kwamba kubwa katika mpango Lengo C-tena.

174
00:09:12,000 --> 00:09:15,000
>> Sasa tumekuwa instantiated darasa hili aitwaye NSObject,

175
00:09:15,000 --> 00:09:19,000
na hii ni darasa random kwamba Apple ina.

176
00:09:19,000 --> 00:09:22,000
Tumekuwa instantiated hii, na sasa nina mfano wa darasa hili

177
00:09:22,000 --> 00:09:25,000
katika hii o kitu, hivyo kwamba maana ya kwamba kama mimi defined

178
00:09:25,000 --> 00:09:29,000
mbinu hizi mimi naweza kuwaita kama hii.

179
00:09:29,000 --> 00:09:31,000
Vile vile, kama mimi alitaka kuwaita mbinu na hoja moja,

180
00:09:31,000 --> 00:09:34,000
hivyo hii ni njia bar, kwamba inachukua moja hoja,

181
00:09:34,000 --> 00:09:38,000
na hapa ni bazi: qux mbinu, hivyo hii inachukua hoja 2.

182
00:09:38,000 --> 00:09:44,000
Hii ni wito moja kazi juu ya hii kitu o.

183
00:09:44,000 --> 00:09:46,000
Mantiki?

184
00:09:46,000 --> 00:09:50,000
syntax lazima mantiki, lakini wewe aina ya kupata kutumika yake.

185
00:09:50,000 --> 00:09:54,000
>> Sawa, hebu majadiliano juu ya mambo machache ambayo ni kujengwa katika Lengo-C

186
00:09:54,000 --> 00:09:56,000
kwamba walikuwa sio lazima kujengwa ndani ya C.

187
00:09:56,000 --> 00:09:59,000
Katika C sisi aina ya alipaswa kushughulika na masharti kama arrays haya kijinga tabia,

188
00:09:59,000 --> 00:10:01,000
na got kweli annoying.

189
00:10:01,000 --> 00:10:04,000
Lengo-C ana wale wote kujengwa katika kwa ajili yetu, na ni kujengwa katika

190
00:10:04,000 --> 00:10:06,000
kutumia darasa aitwaye NSString.

191
00:10:06,000 --> 00:10:10,000
Wakati mimi wanataka kujenga NSString tuna zaidi arcane syntax.

192
00:10:10,000 --> 00:10:15,000
Badala ya kusema "cs50" tunasema @ "cs50"

193
00:10:15,000 --> 00:10:17,000
na hii ni kwa ajili ya kutangaza syntax masharti katika Lengo C-.

194
00:10:17,000 --> 00:10:21,000
Hii ni rahisi sana kusahau, hivyo hawana.

195
00:10:21,000 --> 00:10:24,000
Sasa, mara moja nina hii, hii ni kamba, lakini taarifa

196
00:10:24,000 --> 00:10:26,000
ni kweli tu kitu.

197
00:10:26,000 --> 00:10:30,000
Mimi alisema NSString, ambayo ina maana mimi instantiated darasa

198
00:10:30,000 --> 00:10:32,000
kuitwa NSString, ambayo mtu mwingine aliandika kwa ajili yangu,

199
00:10:32,000 --> 00:10:35,000
na walikuwa nzuri sana kuhusu hilo, na hivyo kwa sasa

200
00:10:35,000 --> 00:10:37,000
Naweza kuanza wito mbinu juu yake.

201
00:10:37,000 --> 00:10:40,000
Kama mimi wito urefu njia hii ya kitu

202
00:10:40,000 --> 00:10:43,000
itakavyo kurudi kwangu urefu wa kamba.

203
00:10:43,000 --> 00:10:45,000
Hii ni kama tu strlen katika C.

204
00:10:45,000 --> 00:10:47,000
Hii atarudi 4.

205
00:10:47,000 --> 00:10:51,000
>> Vilevile, njia nyingine mimi kutaka huduma ya juu ni hii characterAtIndex.

206
00:10:51,000 --> 00:10:54,000
Hii ni njia ya kuwa anasema juu ya hii s string

207
00:10:54,000 --> 00:10:57,000
Mimi nataka wewe kupata tabia 0,

208
00:10:57,000 --> 00:10:59,000
na hivyo hii atarudi kwangu c tabia,

209
00:10:59,000 --> 00:11:02,000
na kuna rundo zima zaidi ya njia hizi kuwa unaweza Google kweli urahisi.

210
00:11:02,000 --> 00:11:07,000
Nyaraka Apple ni kubwa, na tutaweza kuchukua kuangalia kwamba katika kidogo.

211
00:11:07,000 --> 00:11:09,000
Wale ni masharti.

212
00:11:09,000 --> 00:11:11,000
Sisi pia kutofautiana ukubwa arrays kujengwa in

213
00:11:11,000 --> 00:11:13,000
Kumbuka katika C wakati sisi alitangaza safu

214
00:11:13,000 --> 00:11:16,000
tulikuwa na kusema kuwa mambo 5, mwisho wa hadithi.

215
00:11:16,000 --> 00:11:18,000
Tulipofika JavaScript na PHP tunaweza kuanza

216
00:11:18,000 --> 00:11:20,000
kufanya mambo kama vile kuongeza vipengele au kusonga vipengele.

217
00:11:20,000 --> 00:11:22,000
Tunaweza kufanya hivyo katika Lengo C-.

218
00:11:22,000 --> 00:11:26,000
Badala ya kujenga safu katika njia ya kawaida C

219
00:11:26,000 --> 00:11:30,000
tuna tena darasa lingine kuitwa NSMutableArray.

220
00:11:30,000 --> 00:11:33,000
Kuna pia NSArray,

221
00:11:33,000 --> 00:11:35,000
na hii ni kwenda kimsingi kurejelea baadhi safu.

222
00:11:35,000 --> 00:11:38,000
Hii inasema jambo la kwanza nataka kufanya ni nataka kutenga

223
00:11:38,000 --> 00:11:41,000
nafasi kwa ajili ya safu mpya, na baada ya mimi kuipa

224
00:11:41,000 --> 00:11:43,000
Mimi basi haja initialize yake.

225
00:11:43,000 --> 00:11:45,000
Tena, tu wito njia hizi 2.

226
00:11:45,000 --> 00:11:48,000
Sasa hii ina maana kwamba ndani ya kitu hicho katika

227
00:11:48,000 --> 00:11:50,000
Mimi safu tupu ameketi hapo.

228
00:11:50,000 --> 00:11:54,000
Kama mimi nataka kuongeza kitu na safu hii, siwezi kuwaita njia addObject.

229
00:11:54,000 --> 00:11:59,000
Nataka kuongeza kitu kwa safu, na mimi nataka kuongeza string CS50.

230
00:11:59,000 --> 00:12:02,000
Kama nilitaka kinyume chake kuondoa kwamba naweza kusema mimi nataka

231
00:12:02,000 --> 00:12:09,000
kuondoa kitu katika nafasi ya kwanza katika safu au kupinga.

232
00:12:09,000 --> 00:12:11,000
>> Mantiki?

233
00:12:11,000 --> 00:12:14,000
Sawa, wewe aina ya kupata kutumika jambo hili Mabano ya mraba.

234
00:12:14,000 --> 00:12:18,000
Kwa njia, ndani ya mengi ya maktaba Apple utaona hii NS.

235
00:12:18,000 --> 00:12:21,000
NS kweli anasimama kwa hatua ya pili, ambayo ilikuwa moja ya Steve Jobs makampuni ya kwanza,

236
00:12:21,000 --> 00:12:24,000
na hiyo ambapo yeye kweli kuanza kuandika mengi ya maadili ya

237
00:12:24,000 --> 00:12:27,000
kama aina ya msingi kwa ajili ya Mac OS X na aina ya mambo mengine,

238
00:12:27,000 --> 00:12:32,000
na hivyo NS hii ni aina ya urithi hii nice kuita moja ya makampuni ya mapema

239
00:12:32,000 --> 00:12:34,000
nyuma wakati Apple mara ya kwanza kuanzia nje.

240
00:12:34,000 --> 00:12:36,000
Ni kila mahali.

241
00:12:36,000 --> 00:12:41,000
Hebu tuangalie mfano zaidi ya kiujumla Lengo-C.

242
00:12:41,000 --> 00:12:44,000
Mimi hapa ndani ya XCode.

243
00:12:44,000 --> 00:12:47,000
Ili kupata hapa, mimi kwanza kupakuliwa XCode kutoka Hifadhi App,

244
00:12:47,000 --> 00:12:50,000
kufunguliwa it up, na kisha nilikwenda hapa na faili,

245
00:12:50,000 --> 00:12:54,000
zaidi ya hapa na mradi mpya, na kisha.

246
00:12:54,000 --> 00:12:57,000
Baada ya mimi kufanya hivyo nina hizi chaguzi zote za kile wanataka kujenga,

247
00:12:57,000 --> 00:12:59,000
na hivyo tutaweza kuchukua kuangalia chaguzi hizi baadaye,

248
00:12:59,000 --> 00:13:03,000
lakini tu kwa mfano huu, kwa sababu sisi siyo kweli kwenda una programu bado,

249
00:13:03,000 --> 00:13:06,000
Nimeshuka hapa, na mimi alisema amri Line Chombo,

250
00:13:06,000 --> 00:13:09,000
na hii ni programu ambayo ningeweza kukimbia katika mstari amri

251
00:13:09,000 --> 00:13:12,000
tu kama tumekuwa mbio kutoka C.

252
00:13:12,000 --> 00:13:16,000
Hayo ni jinsi mimi umba mradi huu, na hivyo sasa niko hapa,

253
00:13:16,000 --> 00:13:20,000
hivyo hebu kwanza kuangalia faili hili, na hii lazima kuangalia pretty familiar.

254
00:13:20,000 --> 00:13:24,000
Nina jina int. Kuna rafiki yangu argc, rafiki yangu nyingine argv.

255
00:13:24,000 --> 00:13:30,000
Na hivyo tunaweza kuona kwamba hii ni hatua ya kuingia kwa ajili ya maombi yangu ya kwanza Lengo-C.

256
00:13:30,000 --> 00:13:32,000
Hapa tunaweza kupuuza hii kwa sasa.

257
00:13:32,000 --> 00:13:35,000
Hii ni kimsingi baadhi usimamizi kumbukumbu stuff kwamba wewe si kweli

258
00:13:35,000 --> 00:13:37,000
umewahi kuwa na wasiwasi juu.

259
00:13:37,000 --> 00:13:39,000
>> Hebu tuangalie block hii ya kwanza hapa.

260
00:13:39,000 --> 00:13:46,000
Hii mstari wa kwanza, kama mimi kusema Mwanafunzi * alice = [[Mwanafunzi alloc] init] nini kwamba kufanya?

261
00:13:46,000 --> 00:13:50,000
Hii mwanafunzi kwanza hapa, hii pengine ni darasa.

262
00:13:50,000 --> 00:13:54,000
Hii si darasa kwamba Apple aliandika, lakini ni darasa kwamba mimi aliandika.

263
00:13:54,000 --> 00:13:57,000
Jambo la kwanza nataka kufanya ni nataka kutenga nafasi kwa mwanafunzi mpya,

264
00:13:57,000 --> 00:14:00,000
na kisha Mimi nataka initialize hivyo, hivyo hii inatoa mimi nyuma

265
00:14:00,000 --> 00:14:05,000
hii mpya mwanafunzi kitu, na mimi nina hifadhi hii katika variable kuitwa Alice.

266
00:14:05,000 --> 00:14:07,000
Wapi darasa kwamba kuja kutoka?

267
00:14:07,000 --> 00:14:12,000
Naam, zaidi ya hapa upande wa kushoto haya yote ni ya files mbalimbali ndani ya mradi wangu.

268
00:14:12,000 --> 00:14:16,000
Tunaweza kuona hapa nina Student.h na Student.m.

269
00:14:16,000 --> 00:14:20,000
H. SVG, kumbuka, ni pale ambapo mimi kutangaza mambo yote

270
00:14:20,000 --> 00:14:22,000
kwamba zipo ndani ya darasa.

271
00:14:22,000 --> 00:14:25,000
>> Hebu tuangalie kwamba.

272
00:14:25,000 --> 00:14:29,000
Haki zote, hapa tuna hii interface @, na hii anasema kuwa inakuja

273
00:14:29,000 --> 00:14:33,000
maazimio ya kila kitu kile kitakacho kuwepo ndani ya darasa langu.

274
00:14:33,000 --> 00:14:36,000
Basi nina koloni. Basi nina jambo hili NSObject.

275
00:14:36,000 --> 00:14:40,000
Koloni hii kunaashiria kwamba kidogo urithi sisi walikuwa wakijadili kidogo mapema.

276
00:14:40,000 --> 00:14:43,000
Hii anasema kila kitu NSObject wanaweza kufanya

277
00:14:43,000 --> 00:14:46,000
ambapo NSObject ni darasa hili iliyoandikwa na mtu mwingine,

278
00:14:46,000 --> 00:14:50,000
kila kitu NSObject hii inaweza kufanya mimi nataka kuwa na uwezo wa kufanya hivyo.

279
00:14:50,000 --> 00:14:54,000
Kwa kusema: NSObject hiyo ina maana kwamba mimi kimsingi

280
00:14:54,000 --> 00:14:58,000
kurithiwa yote ya utendaji wa darasa lingine.

281
00:14:58,000 --> 00:15:02,000
Kwamba kwa kweli alinipa rundo zima la njia tofauti na mali kwamba naweza kutumia.

282
00:15:02,000 --> 00:15:05,000
Chini hapa nina kujenga tabia ya 2.

283
00:15:05,000 --> 00:15:08,000
Hiyo ina maana mwanafunzi wangu, kama hii walikuwa struct, haya itakuwa mambo 2

284
00:15:08,000 --> 00:15:11,000
ndani ya struct yangu, hivyo kila mwanafunzi ana jina

285
00:15:11,000 --> 00:15:14,000
kwamba ni kamba, na mwanafunzi pia ina daraja,

286
00:15:14,000 --> 00:15:17,000
ambayo ni int.

287
00:15:17,000 --> 00:15:23,000
>> Hatimaye, chini hapa mimi nina kwenda kujenga mbinu kwa ajili ya mwanafunzi wangu.

288
00:15:23,000 --> 00:15:26,000
Mimi kuitwa njia yangu, initWithName, na inachukua moja hoja,

289
00:15:26,000 --> 00:15:31,000
na hoja kuwa ni kamba, na mimi kuitwa ni jina.

290
00:15:31,000 --> 00:15:35,000
Sasa hebu tuangalie jinsi sisi kweli kutekelezwa darasa hili.

291
00:15:35,000 --> 00:15:38,000
Hapa, sasa mimi nina ndani ya. Yangu faili m,

292
00:15:38,000 --> 00:15:40,000
m kwa ajili ya utekelezaji, mimi nadhani.

293
00:15:40,000 --> 00:15:44,000
Nina utekelezaji wangu, mwisho wangu, na hapa ni mahali ambapo Mimi kwa kweli kufafanua

294
00:15:44,000 --> 00:15:47,000
nini initWithName gani.

295
00:15:47,000 --> 00:15:50,000
Nina initWithName, jina la parameter yangu, na kisha hii

296
00:15:50,000 --> 00:15:53,000
ni ambapo Mimi kwa kweli kujenga mwanafunzi,

297
00:15:53,000 --> 00:15:56,000
na hivyo hii ni kidogo cryptic, lakini hii ni aina ya boilerplate

298
00:15:56,000 --> 00:15:58,000
kwamba unataka pamoja katika constructors yako.

299
00:15:58,000 --> 00:16:02,000
Hii kazi initialization hapa, initWithName, ni aina ya kuujenga.

300
00:16:02,000 --> 00:16:05,000
Wewe kimsingi ujenzi mpya mwanafunzi kitu

301
00:16:05,000 --> 00:16:07,000
na labda kupeleka baadhi ya data ndani yake.

302
00:16:07,000 --> 00:16:11,000
Jambo la kwanza nataka kufanya ni nataka kuita init juu ya jambo hili super.

303
00:16:11,000 --> 00:16:15,000
>> Kumbuka kwamba wakati mimi alisema nyuma hapa katika faili h.

304
00:16:15,000 --> 00:16:21,000
kwamba kila kitu NSObject ina mwanafunzi pia ana.

305
00:16:21,000 --> 00:16:24,000
Hiyo ina maana wakati mimi kujenga mwanafunzi kile Mimi pia haja ya kufanya ni

306
00:16:24,000 --> 00:16:28,000
kuhakikisha kwamba NSObject kwamba mimi nina kurithi yote ya data kwamba kutoka

307
00:16:28,000 --> 00:16:32,000
pia initialized vizuri.

308
00:16:32,000 --> 00:16:36,000
Nini nahitaji kusema ni hii super ni kweli kwenda kwa kutaja darasa mzazi

309
00:16:36,000 --> 00:16:39,000
kwamba mimi nina kurithi kutoka, hivyo mimi nataka kuhakikisha mimi initialize

310
00:16:39,000 --> 00:16:43,000
kila kitu kwamba mimi nina kutegemea kabla mimi kuanza kujaribu kuitumia.

311
00:16:43,000 --> 00:16:46,000
Kisha kama kwamba initialized usahihi hii ni kama kusema iwapo malloc

312
00:16:46,000 --> 00:16:50,000
hakurudi null kisha naweza kuanza kuweka baadhi ya mali.

313
00:16:50,000 --> 00:16:54,000
>> Katika JavaScript na PHP tulikuwa Keyword hii inaitwa hii,

314
00:16:54,000 --> 00:16:58,000
na hii inajulikana mfano wa sasa wa darasa.

315
00:16:58,000 --> 00:17:00,000
Katika Lengo C-sisi wito huu wa kujitegemea.

316
00:17:00,000 --> 00:17:04,000
Wakati mimi kusema self.name, hiyo ina maana kwamba kitu

317
00:17:04,000 --> 00:17:07,000
Mimi tu umba wakati mimi alisema mwanafunzi alloc init,

318
00:17:07,000 --> 00:17:09,000
ambayo inaenda nipe nyuma kitu.

319
00:17:09,000 --> 00:17:12,000
Hiyo ina maana Mimi nataka kuweka jina la kitu kwamba

320
00:17:12,000 --> 00:17:15,000
kwa chochote mimi kupita tu in

321
00:17:15,000 --> 00:17:18,000
Tu kama katika C, sisi kupata wanachama na dot hii,

322
00:17:18,000 --> 00:17:21,000
hivyo self.name anasema jina la kitu mwanafunzi

323
00:17:21,000 --> 00:17:24,000
sasa ni kwenda kuwa chochote kupita tu in

324
00:17:24,000 --> 00:17:28,000
Na hivyo hatimaye, siwezi kurudi hivyo mimi kwa kweli kupata kitu nyuma.

325
00:17:28,000 --> 00:17:30,000
>> Maswali?

326
00:17:30,000 --> 00:17:34,000
Sawa, hivyo binafsi hii = super init,

327
00:17:34,000 --> 00:17:37,000
kama huna kabisa kuelewa mambo urithi usijali.

328
00:17:37,000 --> 00:17:40,000
Tu kujua kwamba kama wewe milele unataka kufanya init yako mwenyewe mbinu tu

329
00:17:40,000 --> 00:17:42,000
kufanya hivyo, na wewe utakuwa vizuri kwenda.

330
00:17:42,000 --> 00:17:44,000
Yeah >> [Mwanafunzi]. Gani ikiwa binafsi maana?

331
00:17:44,000 --> 00:17:49,000
Hii ina maana wakati sisi malloc kitu sisi daima checked kama ilikuwa sawa kwa null,

332
00:17:49,000 --> 00:17:51,000
na kama ilikuwa null, basi sisi exited.

333
00:17:51,000 --> 00:17:55,000
Hii ni kitu kimoja, kwa sababu kama hii null anarudi, basi tuko pengine anaenda kosa seg

334
00:17:55,000 --> 00:17:57,000
kama tunataka kuanza kujaribu kuendesha hiyo.

335
00:17:57,000 --> 00:18:01,000
Hiyo ni mwanafunzi wetu darasa.

336
00:18:01,000 --> 00:18:03,000
Hiyo ina maana tunaweza initialize wanafunzi wetu katika moja ya njia mbili.

337
00:18:03,000 --> 00:18:08,000
Nikisema mwanafunzi alloc init mimi si kutumia mbinu ya kwamba kwamba mimi tu aliandika,

338
00:18:08,000 --> 00:18:11,000
na badala yake naweza tu kusema alice.name,

339
00:18:11,000 --> 00:18:14,000
na sasa mimi naenda kuweka kwamba jina mali.

340
00:18:14,000 --> 00:18:17,000
>> Vile vile, kama mimi nataka kutumia kwamba mbinu initWithName

341
00:18:17,000 --> 00:18:20,000
Naweza tu kusema alloc, na kisha badala ya kusema init

342
00:18:20,000 --> 00:18:24,000
Mimi naenda wito kwamba njia ambayo mimi tu umba, na mimi nina kwenda kupita katika Bob.

343
00:18:24,000 --> 00:18:30,000
Katika hatua hii, hii kitu Bob ina jina sawa na Bob.

344
00:18:30,000 --> 00:18:35,000
Okay, chini hapa mimi nina kutumia kwamba NSMutableArray kwamba sisi inaonekana katika mapema.

345
00:18:35,000 --> 00:18:38,000
Mimi nina kugawa space.Then mimi nina initializing safu mpya.

346
00:18:38,000 --> 00:18:40,000
Mimi nina kwenda kuongeza mambo 2 kwa yake.

347
00:18:40,000 --> 00:18:43,000
Safu hii sasa anashikilia vitu mwanafunzi.

348
00:18:43,000 --> 00:18:46,000
Ona kwamba mahali pa gani mimi kusema hii ni safu ya wanafunzi.

349
00:18:46,000 --> 00:18:48,000
Mimi alisema ni safu, kipindi.

350
00:18:48,000 --> 00:18:50,000
Kisha siwezi kuweka chochote ndani yake kwamba mimi nataka.

351
00:18:50,000 --> 00:18:52,000
Hapa nina vitu 2.

352
00:18:52,000 --> 00:18:56,000
>> Hatimaye, mimi na mwingine kitu hapa, hii TF.

353
00:18:56,000 --> 00:18:59,000
Juu hapa nchini TF.h kimsingi kitu kimoja.

354
00:18:59,000 --> 00:19:01,000
Mimi nina kurithi kutoka NSObject, na kwa njia,

355
00:19:01,000 --> 00:19:03,000
wakati wewe kujenga madarasa hii yote ni kufanyika kwa ajili yenu,

356
00:19:03,000 --> 00:19:06,000
aina hii ya boilerplate interface.

357
00:19:06,000 --> 00:19:08,000
Ni ina mali ya wanafunzi.

358
00:19:08,000 --> 00:19:15,000
Nina mbinu michache hapa kwamba si kweli kufanya mengi nzima,

359
00:19:15,000 --> 00:19:18,000
na hivyo kwamba maana baada ya mimi kuunda hii kitu TF

360
00:19:18,000 --> 00:19:23,000
Siwezi kuwaita hii daraja mbinu juu yake kama hii.

361
00:19:23,000 --> 00:19:26,000
Maswali yoyote juu ya syntax Lengo-C kabla ya kuanza kusonga katika baadhi zaidi

362
00:19:26,000 --> 00:19:30,000
programu ya maendeleo ya kuvutia stuff?

363
00:19:30,000 --> 00:19:34,000
>> Sawa, hivyo hebu kweli kufanya App iPhone.

364
00:19:34,000 --> 00:19:39,000
madarasa ya msingi kwamba wewe utakuwa kutumia ndani ya programu yako iPhone wanaitwa mtazamo controllers,

365
00:19:39,000 --> 00:19:42,000
na mtawala mtazamo kimsingi inawakilisha screen moja

366
00:19:42,000 --> 00:19:46,000
ndani ya programu yako, hivyo kama mimi nina juu ya programu ya muziki, kwa mfano,

367
00:19:46,000 --> 00:19:50,000
moja mtazamo mtawala inaweza kuwakilisha mtazamo ambayo mimi mtazamo nyimbo zote iPhone yangu.

368
00:19:50,000 --> 00:19:53,000
Mwingine mtawala mtazamo inaweza kuwa wakati mimi bonyeza wimbo na kuanza kucheza

369
00:19:53,000 --> 00:19:55,000
au kama mimi nina kuchimba chini katika wasanii.

370
00:19:55,000 --> 00:19:59,000
Kila moja ya skrini wale mbalimbali inaweza kuwakilishwa kama mtawala mbalimbali maoni,

371
00:19:59,000 --> 00:20:04,000
na mtawala maoni ni kweli tu kwamba anasema darasa jinsi screen hii kazi.

372
00:20:04,000 --> 00:20:07,000
Mambo ya ndani ya mtawala mtazamo, tunakwenda kuwa na mali,

373
00:20:07,000 --> 00:20:10,000
hivyo mambo kama button ni kwenda kuwa mali ya maoni mtawala wetu.

374
00:20:10,000 --> 00:20:13,000
>> Sisi ni pia kwenda na mbinu, na hizi ni kimsingi tukio handlers.

375
00:20:13,000 --> 00:20:16,000
Njia hii anasema wakati waandishi button hii

376
00:20:16,000 --> 00:20:19,000
Nataka kufanya kitu, na hatimaye, tena,

377
00:20:19,000 --> 00:20:24,000
sisi ni kwenda kuwa na kutumia hii Keyword binafsi kupata mfano wa sasa.

378
00:20:24,000 --> 00:20:29,000
Kujenga interfaces katika iOS ni kweli kweli, kwa kweli ni rahisi.

379
00:20:29,000 --> 00:20:32,000
Wao wana hii Drag nzuri na interface tone kuitwa Interface Mjenzi,

380
00:20:32,000 --> 00:20:37,000
na 2 ya msingi dhana kwamba waya juu yako Lengo C-kwa Interface Builder

381
00:20:37,000 --> 00:20:40,000
ni IBOutlet na IBAction.

382
00:20:40,000 --> 00:20:44,000
IBOutlet tu anasema kwamba kama wewe kutangaza mali hiyo ni kifungo,

383
00:20:44,000 --> 00:20:47,000
na unataka ndoano it up na kitu katika UI yako halisi,

384
00:20:47,000 --> 00:20:49,000
utaenda kusema ni outlet.

385
00:20:49,000 --> 00:20:51,000
Vile vile, kama unataka kuwakilisha handler tukio

386
00:20:51,000 --> 00:20:54,000
basi wewe ni kwenda kusema ni action.

387
00:20:54,000 --> 00:20:57,000
>> Kwa kweli waya up hii uwakilishi graphical

388
00:20:57,000 --> 00:21:00,000
na code yako ni kweli, kweli rahisi.

389
00:21:00,000 --> 00:21:03,000
Kama unataka ambatisha IBOutlet, wote una kufanya ni wewe kudhibiti click,

390
00:21:03,000 --> 00:21:05,000
na tutaweza kuona mfano wa hii kweli haraka.

391
00:21:05,000 --> 00:21:07,000
You kudhibiti bonyeza ambapo anasema View Mdhibiti.

392
00:21:07,000 --> 00:21:09,000
Utaenda Drag katika interface, au kinyume chake,

393
00:21:09,000 --> 00:21:13,000
kama unataka hook up handler tukio utaenda Drag kutoka interface

394
00:21:13,000 --> 00:21:15,000
katika upande mwingine.

395
00:21:15,000 --> 00:21:20,000
Hebu tuangalie mfano kweli rahisi iOS.

396
00:21:20,000 --> 00:21:23,000
>> Hebu kujenga mradi mpya.

397
00:21:23,000 --> 00:21:25,000
Mimi naenda kuja hapa kwa Maombi,

398
00:21:25,000 --> 00:21:28,000
na mimi naenda bonyeza Single View Maombi.

399
00:21:28,000 --> 00:21:31,000
Mimi naenda bonyeza ijayo. Nitapatia mradi wangu jina.

400
00:21:31,000 --> 00:21:33,000
Mimi nitakuita ni Hello.

401
00:21:33,000 --> 00:21:36,000
Inafurahisha, Apple akubali wewe ni kujenga bidhaa

402
00:21:36,000 --> 00:21:38,000
ili uweze kuuza na wanaweza kupata pesa.

403
00:21:38,000 --> 00:21:41,000
Chini hapa mimi nina kwenda kusema kwamba hii ni App iPhone.

404
00:21:41,000 --> 00:21:44,000
Unaweza kuunda programu iPad, au kama unataka kujenga moja ya programu hizo

405
00:21:44,000 --> 00:21:47,000
kwamba inasaidia vifaa wote unaweza kufanya hivyo pia.

406
00:21:47,000 --> 00:21:49,000
Hizi ni nini unataka checkmarks wako kuangalia kama.

407
00:21:49,000 --> 00:21:51,000
>> Unataka kutumia storyboards, ambayo tutaweza kuona baadaye,

408
00:21:51,000 --> 00:21:54,000
na wewe dhahiri wanataka kutumia moja kwa moja ya kumbukumbu ya kuhesabu,

409
00:21:54,000 --> 00:21:58,000
ambayo ni hulka nzuri kwamba kuzuia kutoka kuwa kusema malloc na bure.

410
00:21:58,000 --> 00:22:03,000
Kama unataka kuwaita malloc na bure, napenda kuondoka checked.

411
00:22:03,000 --> 00:22:07,000
Mimi itabidi bonyeza pili, na hatimaye, hii ni ya kwenda kuuliza mimi ambapo nataka atayaokoa.

412
00:22:07,000 --> 00:22:14,000
Mimi itabidi hit kujenga, na hapa sisi kwenda.

413
00:22:14,000 --> 00:22:16,000
Mimi umba mradi mpya.

414
00:22:16,000 --> 00:22:19,000
Zaidi ya hapa upande wa kushoto ni mafaili yote ambayo ni ya ndani ya mradi wangu,

415
00:22:19,000 --> 00:22:22,000
na taarifa kwamba mimi got rundo zima, na sikuweza hata kufanya kitu chochote.

416
00:22:22,000 --> 00:22:24,000
IOs ni kubwa.

417
00:22:24,000 --> 00:22:27,000
>> Kwa mfano, hapa hii ViewController.h,

418
00:22:27,000 --> 00:22:30,000
hii ni kwenda kuwakilisha mtazamo wangu wa kwanza mtawala,

419
00:22:30,000 --> 00:22:32,000
hivyo screen kwanza ndani ya programu yangu.

420
00:22:32,000 --> 00:22:34,000
Sasa sisi kujua nini hii ni kusema.

421
00:22:34,000 --> 00:22:36,000
Sisi ni kusema mimi nina wito huu ViewController darasa,

422
00:22:36,000 --> 00:22:40,000
na ViewController anafanya kila kitu ambacho UIViewController gani,

423
00:22:40,000 --> 00:22:43,000
na hili, tena, ni baadhi ya darasa kwamba Apple aliandika kwamba hana mengi ya mambo Handy kwa ajili yetu

424
00:22:43,000 --> 00:22:46,000
kama kuonyesha screen.

425
00:22:46,000 --> 00:22:50,000
Hapa ni mahali ambapo kweli mimi kuanza kufafanua nini mtazamo wangu mtawala gani,

426
00:22:50,000 --> 00:22:52,000
na zinageuka kuwa mimi kweli hawana haja yoyote ya hii.

427
00:22:52,000 --> 00:22:55,000
Hii ni boilerplate kificho kwamba Apple anitiaye kwa bure.

428
00:22:55,000 --> 00:22:59,000
Nilifanya haja ya kuwa mstari wa kwanza, au sina darasa,

429
00:22:59,000 --> 00:23:02,000
hivyo tunaweza kujikwamua kwamba na kujikwamua hii.

430
00:23:02,000 --> 00:23:05,000
Sawa, hivyo hii ni screen yangu tupu.

431
00:23:05,000 --> 00:23:08,000
>> Sasa hebu bonyeza MainStoryboard.storyboard hii,

432
00:23:08,000 --> 00:23:11,000
na hii ni mahali ambapo ni kuanza kupata kuvutia.

433
00:23:11,000 --> 00:23:14,000
Hii inawakilisha screen kwanza juu ya programu yangu.

434
00:23:14,000 --> 00:23:17,000
Kama mimi nataka kuongeza kifungo, katika HTML nilikuwa na kujenga tag button.

435
00:23:17,000 --> 00:23:20,000
Katika Android una kuunda tag kifungo,

436
00:23:20,000 --> 00:23:23,000
lakini katika iOS kama mimi tu kuja chini hapa kwa haki ya chini

437
00:23:23,000 --> 00:23:27,000
na ikiwa mimi bonyeza mmoja hii 3 hapa ambapo anasema vitu,

438
00:23:27,000 --> 00:23:31,000
na mimi unaweza kitabu chini, au naweza kuanza kutafuta button.

439
00:23:31,000 --> 00:23:35,000
Na kuangalia, kifungo, hivyo kama mimi kweli Drag na kuacha hii haki pale,

440
00:23:35,000 --> 00:23:38,000
Nimekuwa tu aliongeza button hii screen juu ya programu yangu.

441
00:23:38,000 --> 00:23:41,000
Kama mimi nataka kubadili Nakala, siwezi bonyeza mara mbili yake,

442
00:23:41,000 --> 00:23:47,000
kusema kitu Huwaongoza kama "Vyombo vya habari Mimi."

443
00:23:47,000 --> 00:23:51,000
Okay, sasa kama mimi kukimbia programu hii, hivyo sisi kukusanya yake,

444
00:23:51,000 --> 00:23:54,000
hivyo kwa kukimbia mimi bonyeza kifungo kucheza katika upande wa juu kushoto, na kuna programu yangu.

445
00:23:54,000 --> 00:23:58,000
Sikuweza kufanya kitu chochote, na I got tamu kuangalia iPhone App.

446
00:23:58,000 --> 00:24:01,000
Kama mimi nataka kuacha ni, unaweza bonyeza button kuacha

447
00:24:01,000 --> 00:24:03,000
kwa sababu ni furaha zaidi.

448
00:24:03,000 --> 00:24:07,000
>> Hebu kusema kwamba mimi kweli wanataka kitu kutokea wakati mimi waandishi wa button hii.

449
00:24:07,000 --> 00:24:09,000
Ili kufanya hivyo nini mimi haja ya kufanya ni mimi haja ya kuunda

450
00:24:09,000 --> 00:24:13,000
mpya tukio handler au action.

451
00:24:13,000 --> 00:24:16,000
Hiyo ina maana kwamba mimi haja ya kuunda baadhi njia ambayo Mimi nataka kuitwa

452
00:24:16,000 --> 00:24:18,000
wakati mimi waandishi wa habari kifungo, hivyo hebu kuunda mbinu mpya.

453
00:24:18,000 --> 00:24:20,000
Mimi nina ndani ya ViewController.h.

454
00:24:20,000 --> 00:24:22,000
Mimi haja ya kusema kwamba njia ipo.

455
00:24:22,000 --> 00:24:26,000
Nahitaji hyphen kwanza kwa sababu mimi nina kwenda kuwa wito huu juu ya mtawala mtazamo.

456
00:24:26,000 --> 00:24:28,000
Mimi haja ya kutoa aina hii.

457
00:24:28,000 --> 00:24:31,000
aina ya hii ni ya kwenda kuwa kitu IBAction kuwa tuliona mapema.

458
00:24:31,000 --> 00:24:35,000
Hii ni handler tukio hilo, hivyo ni kwenda na kurudi IBAction,

459
00:24:35,000 --> 00:24:38,000
na hii ni dokezo kwa XCode kusema kwamba

460
00:24:38,000 --> 00:24:40,000
hili ni jambo nataka waya kitu.

461
00:24:40,000 --> 00:24:45,000
Naweza kutoa jina, kama semicolon buttonPressed,.

462
00:24:45,000 --> 00:24:48,000
>> Sasa nimepata alitangaza mbinu mpya ndani ya darasa langu.

463
00:24:48,000 --> 00:24:50,000
Nilivyosema njia hii ina kuwepo.

464
00:24:50,000 --> 00:24:53,000
Sasa hebu kuja katika ViewController.m,

465
00:24:53,000 --> 00:24:56,000
na hebu sema nini njia hii inaweza kufanya.

466
00:24:56,000 --> 00:25:03,000
Kama mimi kuanza kuandika, kwa mfano, (utupu) buttonPressed

467
00:25:03,000 --> 00:25:06,000
taarifa XCode ni kweli nice na autocompletes kwa ajili yangu.

468
00:25:06,000 --> 00:25:09,000
Hiyo ni kweli ajabu.

469
00:25:09,000 --> 00:25:12,000
Ona hapa kwamba ndani ya faili. M pia naweza kusema batili,

470
00:25:12,000 --> 00:25:15,000
na hii ni kwa sababu IBAction kwamba ni kweli si aina.

471
00:25:15,000 --> 00:25:19,000
Ni kweli hashtag defined mahali fulani kuwa utupu,

472
00:25:19,000 --> 00:25:22,000
na tena, hii ni dokezo kwa XCode kwamba anasema

473
00:25:22,000 --> 00:25:25,000
Nataka hii kuwa handler tukio hilo, na tutaweza kuona nini katika haki ya pili.

474
00:25:25,000 --> 00:25:28,000
Wakati kifungo hii ni taabu mimi naenda kufanya kitu annoying

475
00:25:28,000 --> 00:25:30,000
kama kuonyesha popup.

476
00:25:30,000 --> 00:25:35,000
>> Ili kufanya hivyo naweza kujenga mfano mpya wa darasa hili aitwaye UIAlertView,

477
00:25:35,000 --> 00:25:39,000
na hii ni darasa kwamba Apple aliandika kwamba kinaendelea kuonyesha popups annoying.

478
00:25:39,000 --> 00:25:43,000
Tutamwita tahadhari hii popup, na mimi kuwa hatua 2, kumbuka, kwa kujenga hii kitu.

479
00:25:43,000 --> 00:25:46,000
Jambo la kwanza mimi haja ya kufanya ni kutenga nafasi.

480
00:25:46,000 --> 00:25:48,000
Mimi nataka UIAlertView.

481
00:25:48,000 --> 00:25:51,000
Mimi nataka kutenga nafasi. Hiyo ni njia yangu ya kwanza.

482
00:25:51,000 --> 00:25:53,000
Njia yangu ya pili ni mimi nataka initialize yake,

483
00:25:53,000 --> 00:25:58,000
na hivyo nina hii kubwa, muda mrefu njia iitwayo initWithTitle.

484
00:25:58,000 --> 00:26:01,000
Hiyo kimsingi kwenda kudhibiti kile dukizi hii anasema.

485
00:26:01,000 --> 00:26:04,000
hatimiliki ya popup yangu inaweza kuwa hello.

486
00:26:04,000 --> 00:26:08,000
ujumbe wa hii popup wanaweza kuwa "Hii ni iOS."

487
00:26:08,000 --> 00:26:10,000
Mjumbe kitu, sijui nini ni kwamba.

488
00:26:10,000 --> 00:26:13,000
Hebu sema ni kitu.

489
00:26:13,000 --> 00:26:18,000
Sasa kifungo ambayo inaenda kuonekana unaweza kusema kitu kama "Ni uhakika ni,"

490
00:26:18,000 --> 00:26:24,000
na mimi si kweli unataka vifungo nyingine yoyote, hivyo hebu kufuta kwamba karibu na bracket.

491
00:26:24,000 --> 00:26:27,000
>> Sawa, mimi umba moja ya ziada. Kuna sisi kwenda.

492
00:26:27,000 --> 00:26:30,000
Hii ni jinsi gani naweza kujenga popup mpya.

493
00:26:30,000 --> 00:26:35,000
Kama mimi nataka kuonyesha kweli popup nataka kuita njia show.

494
00:26:35,000 --> 00:26:38,000
Ili kufanya hivyo naweza kusema tahadhari na show,

495
00:26:38,000 --> 00:26:40,000
na tena, oto kukamilisha alikuwa super nice.

496
00:26:40,000 --> 00:26:42,000
Kama mimi nilimsahau nini kwamba ilikuwa, kama mimi tu typed katika s,

497
00:26:42,000 --> 00:26:45,000
Mimi unaweza kitabu kupitia hapa kufikiri nini ilikuwa,

498
00:26:45,000 --> 00:26:48,000
na filters nicely.

499
00:26:48,000 --> 00:26:52,000
Sasa mimi aliumba hii popup mpya.

500
00:26:52,000 --> 00:26:55,000
Tutaweza kuja nyuma kwa nini mjumbe maana baadaye,

501
00:26:55,000 --> 00:26:58,000
na sasa mimi nataka kusema nataka njia hii kuwa fired

502
00:26:58,000 --> 00:27:01,000
wakati mimi waandishi wa habari kifungo, hivyo mimi nina kwenda kurudi kwenye Muhtasari yangu,

503
00:27:01,000 --> 00:27:04,000
na mimi nataka sasa ambatisha hii IBAction.

504
00:27:04,000 --> 00:27:06,000
Jambo la kwanza unataka kufanya ni bonyeza button.

505
00:27:06,000 --> 00:27:08,000
Wakati mimi bonyeza button hii nataka kitu kutokea.

506
00:27:08,000 --> 00:27:10,000
Sitakuja kushikilia chini ya udhibiti.

507
00:27:10,000 --> 00:27:13,000
Mimi naenda bonyeza na Drag kutoka kifungo

508
00:27:13,000 --> 00:27:15,000
kwa zaidi ya hapa ambapo anasema View Mdhibiti.

509
00:27:15,000 --> 00:27:17,000
Tunaweza kuona kwamba ni nicely taa juu.

510
00:27:17,000 --> 00:27:22,000
>> Kama mimi basi kwenda na kipanya yangu mimi sasa hii popup zaidi ya hapa ambapo mimi baadhi ya chaguzi.

511
00:27:22,000 --> 00:27:24,000
Moja ya hayo ni matukio ambayo naweza kujisajili.

512
00:27:24,000 --> 00:27:28,000
Haya yote ni ya njia hizo mimi alitangaza katika faili yangu h kama IBActions.

513
00:27:28,000 --> 00:27:31,000
Hii ni jinsi XCode anajua nini wanapaswa kuonekana katika orodha hii ndogo,

514
00:27:31,000 --> 00:27:33,000
hivyo kwamba tu ladha.

515
00:27:33,000 --> 00:27:37,000
Kama mimi bonyeza kifungo taabu, nimekuwa sasa kusajiliwa handler tukio hilo.

516
00:27:37,000 --> 00:27:41,000
Katika JavaScript sisi alikuwa na kusema mimi na baadhi ya kificho kwamba kusajiliwa handler tukio hilo.

517
00:27:41,000 --> 00:27:43,000
Katika Lengo C-ni kweli kwamba rahisi.

518
00:27:43,000 --> 00:27:46,000
Kama mimi kukimbia hii tena

519
00:27:46,000 --> 00:27:49,000
sasa wakati mimi waandishi wa habari kifungo tukio yangu handler ni kwenda kwa moto,

520
00:27:49,000 --> 00:27:51,000
na mimi naenda kupata hii popup.

521
00:27:51,000 --> 00:27:54,000
Super, super rahisi huko.

522
00:27:54,000 --> 00:27:57,000
>> Kama umewahi wanataka kuona matukio yote ya kuwa kutokea kwa kuandikishwa

523
00:27:57,000 --> 00:28:00,000
juu ya sehemu kama mimi bonyeza button hii

524
00:28:00,000 --> 00:28:02,000
na mimi kuja hapa kwa upande wa kulia

525
00:28:02,000 --> 00:28:05,000
kwanza unaweza kuona zaidi ya hapa Naweza kufanya mambo kama aina ya kifungo,

526
00:28:05,000 --> 00:28:08,000
hivyo kama unataka mmoja wa wale wa mimi au kuongeza kifungo mawasiliano

527
00:28:08,000 --> 00:28:10,000
au chochote.

528
00:28:10,000 --> 00:28:13,000
Kama nataka kuona matukio yote ya kwamba ni juu ya kifungo hii

529
00:28:13,000 --> 00:28:16,000
nikija njia yote juu hapa kwa upande wa kulia

530
00:28:16,000 --> 00:28:19,000
tunaweza kuona hapa katika matukio nina matukio haya yote tofauti.

531
00:28:19,000 --> 00:28:23,000
Naweza waandishi wa habari kifungo, wakati mimi basi kwenda ya kifungo, wakati mimi mara mbili bomba au chochote,

532
00:28:23,000 --> 00:28:26,000
na moja mimi waliojiandikisha tu ni tukio hili aitwaye Touch Up Ndani,

533
00:28:26,000 --> 00:28:29,000
na hii anasema kwamba haraka kama kidole changu anakuja mbali kifungo

534
00:28:29,000 --> 00:28:32,000
kuwa tukio ni kwenda moto, na kwamba ni nini hasa ilitokea tu.

535
00:28:32,000 --> 00:28:36,000
Hii ni aina ya tukio default kifungo taabu.

536
00:28:36,000 --> 00:28:39,000
>> Maswali yoyote hadi sasa?

537
00:28:39,000 --> 00:28:43,000
Okay, hiyo ni jinsi tunaweza kuanza kwa waya juu ya mambo katika code yetu

538
00:28:43,000 --> 00:28:46,000
katika mambo ya ndani ya interface yetu.

539
00:28:46,000 --> 00:28:49,000
Kumbuka jambo la kwanza sisi na kufanya ni kupata code,

540
00:28:49,000 --> 00:28:54,000
na kisha sisi wired up interface kwa kificho,

541
00:28:54,000 --> 00:28:57,000
na kuna programu yetu ya kwanza.

542
00:28:57,000 --> 00:29:00,000
Okay, kwamba ilikuwa kweli baridi, na sisi aliumba hii kifungo.

543
00:29:00,000 --> 00:29:03,000
Nini kama sisi si unataka kuwa na kuunda kundi la mali

544
00:29:03,000 --> 00:29:05,000
anayewakilisha vifungo haya?

545
00:29:05,000 --> 00:29:08,000
Kwa mfano, katika Tic TAC Toe nina vifungo 9,

546
00:29:08,000 --> 00:29:11,000
na ni d kuwa super, super annoying kuwa kwa Drag na kuacha mara 9

547
00:29:11,000 --> 00:29:14,000
au kama mimi alikuwa na kufanya Tic TAC Toe na 81 badala ya 9

548
00:29:14,000 --> 00:29:17,000
na mimi alikuwa na Drag na kuacha mara 81, na kwamba ni kilema.

549
00:29:17,000 --> 00:29:20,000
Nini tunaweza kufanya badala yake ni kiasi kama HTML

550
00:29:20,000 --> 00:29:23,000
wakati tulikuwa na vitu kama Vitambulisho majina na tunaweza kutafuta mambo

551
00:29:23,000 --> 00:29:27,000
na ID zao, kuna wazo sawa katika iOS kuitwa tags.

552
00:29:27,000 --> 00:29:31,000
>> tag ni tu kipekee namba kitambulisho kwa sehemu.

553
00:29:31,000 --> 00:29:34,000
Kama mimi kusema hii ina tag wa 0, kwa mfano,

554
00:29:34,000 --> 00:29:38,000
kama mimi kujenga kifungo na kuwapa tag wa 0, na tutaweza kuona jinsi ya kufanya kwamba katika haki ya pili,

555
00:29:38,000 --> 00:29:41,000
kama nataka kupata kwamba kifungo naweza tu kusema mimi nataka kuita

556
00:29:41,000 --> 00:29:45,000
, viewWithTag njia juu ya kitu zaidi ya hapa

557
00:29:45,000 --> 00:29:48,000
self.view, ambayo inawakilisha screen ya sasa, kwa mfano.

558
00:29:48,000 --> 00:29:53,000
Kama mimi wito kwamba njia viewWithTag, mimi nina kwenda kuvuta nyuma kifungo na tag 0.

559
00:29:53,000 --> 00:29:58,000
Hebu tuangalie hili kwa toe jengo Tic TAC.

560
00:29:58,000 --> 00:30:01,000
Kwanza, hii ni storyboard yangu.

561
00:30:01,000 --> 00:30:05,000
Nimekuwa umba hizi vifungo UI 10.

562
00:30:05,000 --> 00:30:07,000
Angalia wao uko ukubwa wote ni sawa.

563
00:30:07,000 --> 00:30:11,000
Kama mimi bonyeza mmoja wa hawa na mimi kuja nyuma zaidi ya hapa, upande huu wa kulia

564
00:30:11,000 --> 00:30:15,000
utaona mimi kurekebishwa font haki hapa, hivyo mimi alifanya font kidogo kubwa zaidi,

565
00:30:15,000 --> 00:30:19,000
lakini kile Mimi pia alifanya alikuwa mimi kuweka hii tag.

566
00:30:19,000 --> 00:30:23,000
Mimi alisema kwamba hii ina tag wa 1, na kwamba upande wa juu kushoto.

567
00:30:23,000 --> 00:30:26,000
>> Sasa, kama mimi bonyeza kifungo mwingine, kama hii moja ya pili hapa,

568
00:30:26,000 --> 00:30:29,000
sasa utaona kwamba lebo yangu ni 2.

569
00:30:29,000 --> 00:30:32,000
Kila moja ya vifungo hizi tu ana tag kipekee,

570
00:30:32,000 --> 00:30:35,000
na hivyo hii ni baadaye jinsi mimi nina kwenda kuanza mazungumzo

571
00:30:35,000 --> 00:30:38,000
na programu yangu.

572
00:30:38,000 --> 00:30:40,000
Hii yote ni ndani ya moja mtawala view,

573
00:30:40,000 --> 00:30:42,000
lakini hapa ni nini sisi.

574
00:30:42,000 --> 00:30:44,000
Tuna mali 3 hapa.

575
00:30:44,000 --> 00:30:49,000
moja ya kwanza na ile ya mwisho ni kwenda kuwakilisha hali ya bodi yangu.

576
00:30:49,000 --> 00:30:53,000
Kimsingi hii ni moja ya kwanza safu anayewakilisha ambapo XS na Os ni.

577
00:30:53,000 --> 00:30:57,000
Hii moja nyingine hapa inatuambia zamu ya nani ni.

578
00:30:57,000 --> 00:31:01,000
Utagundua kuwa mimi pia kuwa mambo haya hapa.

579
00:31:01,000 --> 00:31:05,000
Kabla ya wakati sisi alitangaza mali sisi aliwapa jina na aina.

580
00:31:05,000 --> 00:31:08,000
Tunaweza pia kuwapa baadhi ya maelezo ya ziada hapa.

581
00:31:08,000 --> 00:31:11,000
Hii kwanza anasema nonatomic, na nini hii anasema

582
00:31:11,000 --> 00:31:16,000
kimsingi ni jambo moja tu ataweza kujaribu kupata hii variable wakati.

583
00:31:16,000 --> 00:31:19,000
Unaweza kufanya maombi zaidi tata kwamba ni multi-mnyororo,

584
00:31:19,000 --> 00:31:22,000
na hivyo nyuma katika Scratch tulikuwa threads tofauti,

585
00:31:22,000 --> 00:31:25,000
na sprites mbalimbali inaweza kufanya mambo mbalimbali kwa wakati mmoja.

586
00:31:25,000 --> 00:31:29,000
>> Kama hiyo si kesi, ambayo si katika kitu chochote kwamba tutaweza kuwa na kuangalia,

587
00:31:29,000 --> 00:31:33,000
tukisema nonatomic ni kweli kwenda kufanya mambo kidogo kidogo kwa kasi zaidi.

588
00:31:33,000 --> 00:31:37,000
Sisi pia kuwa hii kitu kinachoitwa hawawajui, nguvu, au dhaifu.

589
00:31:37,000 --> 00:31:40,000
Hii hawawajui tu anasema kwamba hii ni aina ya kiwango.

590
00:31:40,000 --> 00:31:43,000
Hii si kitu au pointer kwa sababu hii ni bool,

591
00:31:43,000 --> 00:31:46,000
hivyo bool ni kujengwa katika Lengo C-.

592
00:31:46,000 --> 00:31:49,000
Hii inasema wala kujaribu kufanya kitu chochote dhana na kuyatumia hapa.

593
00:31:49,000 --> 00:31:51,000
Ni kawaida ya zamani scaler.

594
00:31:51,000 --> 00:31:54,000
Nguvu na dhaifu, hii dhaifu anasema kwamba kwa kweli

595
00:31:54,000 --> 00:31:57,000
Nataka hii kuwa akizungumzia kitu katika mtazamo mtawala.

596
00:31:57,000 --> 00:32:00,000
Sitakuja kwa kweli kutenga au init hii mwenyewe.

597
00:32:00,000 --> 00:32:04,000
wajenzi interface, wakati mimi kukimbia programu, ni kwenda kushughulikia initialization kwamba wote.

598
00:32:04,000 --> 00:32:07,000
Nikisema dhaifu, kwamba anasema mtu mwingine ni kwenda kujenga hii.

599
00:32:07,000 --> 00:32:09,000
Nikisema nguvu, hii anasema kwamba mimi nina kwenda kuwa moja

600
00:32:09,000 --> 00:32:12,000
hiyo ni kujenga hii kitu bodi,

601
00:32:12,000 --> 00:32:14,000
na hivyo hapa nina mbinu baadhi zaidi hapa,

602
00:32:14,000 --> 00:32:18,000
kwa mfano, hatua kwa wakati mpya kifungo mchezo ni taabu,

603
00:32:18,000 --> 00:32:20,000
utekelezaji kwa wakati yoyote ya kifungo nyingine ni taabu,

604
00:32:20,000 --> 00:32:23,000
na kadhalika.

605
00:32:23,000 --> 00:32:26,000
>> Sisi si kupata ndani ya sana wa mantiki ya Tic TAC Toe,

606
00:32:26,000 --> 00:32:30,000
ingawa ni ya kusisimua sana, lakini hebu tuangalie

607
00:32:30,000 --> 00:32:33,000
baadhi ya mambo ambayo tunaweza kufanya ndani ya iOS.

608
00:32:33,000 --> 00:32:35,000
Hii mpya mchezo mbinu ni kwenda kuwa fired

609
00:32:35,000 --> 00:32:37,000
wakati mimi waandishi mpya mchezo button.

610
00:32:37,000 --> 00:32:41,000
Kwa ndoano kuwa hadi mimi tu kuja juu kwenye Muhtasari yangu.

611
00:32:41,000 --> 00:32:43,000
Mimi clicked juu ya mchezo mpya.

612
00:32:43,000 --> 00:32:47,000
Kama mimi kuja hapa kwa haki mimi kuona kwamba

613
00:32:47,000 --> 00:32:50,000
Kugusa Up Inside ni wired njia newGame.

614
00:32:50,000 --> 00:32:53,000
Hiyo ndiyo sababu hii ni kwenda kupata fired.

615
00:32:53,000 --> 00:32:56,000
Njia newGame anaenda kufanya baadhi ya kuweka juu.

616
00:32:56,000 --> 00:32:59,000
Ni kwenda kusema mimi nataka wewe wazi hali ya bodi.

617
00:32:59,000 --> 00:33:01,000
Hii ni njia nzuri juu ya arrays mutable.

618
00:33:01,000 --> 00:33:03,000
Hii ni kwenda kusema ni sasa upande wa X,

619
00:33:03,000 --> 00:33:07,000
na sasa mimi naenda kuchukua faida ya jambo hili viewWithTag.

620
00:33:07,000 --> 00:33:11,000
>> Najua kwamba vifungo yangu kuwa tags 1-9,

621
00:33:11,000 --> 00:33:13,000
na kwamba ni kitu mimi kiholela ilichukua.

622
00:33:13,000 --> 00:33:15,000
Kama mimi nataka kuweka Nakala ya kifungo kila kuwa tupu

623
00:33:15,000 --> 00:33:17,000
kwa sababu mimi tu ya kuanza mchezo mpya na sitaki yoyote

624
00:33:17,000 --> 00:33:20,000
XS au Os kuwa kushoto juu naweza kufanya hili.

625
00:33:20,000 --> 00:33:24,000
Naweza kusema mimi nataka mtazamo na tag, 1, 2, 3, 4 nakadhalika.

626
00:33:24,000 --> 00:33:27,000
Hii kuvuta kifungo tofauti kila wakati.

627
00:33:27,000 --> 00:33:30,000
Hapa nina kwenda kuwatupia UIButton.

628
00:33:30,000 --> 00:33:33,000
Tu kama sisi inaweza kutupwa ints kwa ikifungwa na kinyume chake

629
00:33:33,000 --> 00:33:37,000
hii anasema kuwa nataka kutupwa hii UIButton.

630
00:33:37,000 --> 00:33:40,000
Hiyo ina maana ya aina ya hii itakuwa * UIButton

631
00:33:40,000 --> 00:33:43,000
kwa sababu ya kuyatumia, lakini usijali, wao siyo inatisha tena.

632
00:33:43,000 --> 00:33:47,000
>> Mara baada ya mimi kuwa na kifungo nitakacho kuwaita njia juu yake.

633
00:33:47,000 --> 00:33:50,000
Mbinu hii hujulikana setTitle forState, na hivyo hii anasema

634
00:33:50,000 --> 00:33:53,000
Nataka kuweka Nakala ya kifungo kuwa string tupu,

635
00:33:53,000 --> 00:33:57,000
na mimi nataka kuwa string tupu wakati siyo taabu.

636
00:33:57,000 --> 00:34:01,000
Kama mimi nina kutumia njia hii, naweza kubadili Nakala ya kifungo

637
00:34:01,000 --> 00:34:04,000
haraka kama mtu hits, lakini tunataka kusema wakati button wamekaa tu pale

638
00:34:04,000 --> 00:34:07,000
Mimi nataka Nakala kuwa tupu.

639
00:34:07,000 --> 00:34:10,000
Hatimaye, tunakwenda initialize bodi yangu,

640
00:34:10,000 --> 00:34:12,000
na mimi nina kwenda kusema kuwa kila kitu sasa ni 0,

641
00:34:12,000 --> 00:34:15,000
hivyo hii wajumbe wa bodi hayabadiliki ni safu mutable,

642
00:34:15,000 --> 00:34:21,000
ambayo ina maana siwezi kuwaita njia addObject na tu ndani 0 yake.

643
00:34:21,000 --> 00:34:23,000
Hiyo ni nini kinatokea wakati mimi kujenga mchezo mpya.

644
00:34:23,000 --> 00:34:25,000
>> Hebu tuangalie mwingine mmoja.

645
00:34:25,000 --> 00:34:28,000
Njia hii hapa ni IBAction ambayo inaenda kuwa taabu

646
00:34:28,000 --> 00:34:31,000
wakati kila mmoja wa miraba wale ni taabu.

647
00:34:31,000 --> 00:34:33,000
Sasa tuna baadhi Tic TAC Toe mantiki hapa.

648
00:34:33,000 --> 00:34:36,000
Sisi takwimu nje zamu ya nani ni,

649
00:34:36,000 --> 00:34:39,000
na kwa kuzingatia kwamba sisi ama kuweka X au O,

650
00:34:39,000 --> 00:34:43,000
lakini sisi taarifa kwamba sisi ni Reusing hiyo tukio handler

651
00:34:43,000 --> 00:34:45,000
kwa kila moja ya vifungo hizo.

652
00:34:45,000 --> 00:34:49,000
Hiyo ina maana kwamba mimi si kuwa mbinu kwa ajili ya kifungo juu kushoto,

653
00:34:49,000 --> 00:34:52,000
njia tofauti ya batani ya kulia chini, ingawa mimi naweza kuwa amefanya hivyo.

654
00:34:52,000 --> 00:34:54,000
Hiyo si kweli kuwa nzuri design.

655
00:34:54,000 --> 00:34:57,000
Nini mimi kufanya hapa ni mimi nina kweli kwenda kuamua

656
00:34:57,000 --> 00:35:00,000
nini tag wa kifungo kwamba ilikuwa taabu ni.

657
00:35:00,000 --> 00:35:04,000
Taarifa kwamba njia hii inachukua kucheza moja hoja.

658
00:35:04,000 --> 00:35:07,000
Ni wito mtumaji, na kile mtumaji ni ni mtumaji ni kwenda

659
00:35:07,000 --> 00:35:10,000
kuwakilisha nini hasa ilikuwa kuchukuliwa hatua juu ya.

660
00:35:10,000 --> 00:35:15,000
Kama mimi waandishi wa habari kifungo, mtumaji hii ni ya kwenda kuwa UIButton

661
00:35:15,000 --> 00:35:18,000
kwamba mimi kwa kweli taabu, hivyo hiyo ina maana kwamba kuwa UIButton

662
00:35:18,000 --> 00:35:20,000
ina tag sababu mimi umba tag.

663
00:35:20,000 --> 00:35:23,000
>> Kama mimi nataka kupata saa tag naweza tu kusema

664
00:35:23,000 --> 00:35:26,000
Mimi nataka tag wa mtumaji,

665
00:35:26,000 --> 00:35:28,000
na tena, nimekuwa tu casted kwa UIButton.

666
00:35:28,000 --> 00:35:32,000
Mimi kutokea kwa kujua kwamba mtumaji itakuwa UIButton.

667
00:35:32,000 --> 00:35:34,000
Haina daima kuwa UIButton.

668
00:35:34,000 --> 00:35:36,000
Mimi naweza, kwa mfano, kujiandikisha huo tukio handler

669
00:35:36,000 --> 00:35:38,000
 kwa moja kwa kifungo, moja kwa slider.

670
00:35:38,000 --> 00:35:40,000
Katika kesi hiyo, najua uko wote vifungo, hivyo mimi nina kwenda kusema

671
00:35:40,000 --> 00:35:43,000
Nataka hii kuwa kifungo, na kisha naweza kupata tag,

672
00:35:43,000 --> 00:35:48,000
na kutoka tag Mimi sasa kujua ambapo mimi ni ndani ya bodi.

673
00:35:48,000 --> 00:35:51,000
Kisha mimi anaweza tu kuweka aidha X au O, unaweza flip upande,

674
00:35:51,000 --> 00:35:54,000
kuangalia ambaye ameshinda, nakadhalika.

675
00:35:54,000 --> 00:35:59,000
>> Maswali yoyote juu ya hili hadi sasa?

676
00:35:59,000 --> 00:36:02,000
Okay, code wote sisi posted online-hatutaki kupata ndani sana

677
00:36:02,000 --> 00:36:06,000
Tic TAC ya mantiki toe, lakini sasa unaweza kuona kwamba kweli

678
00:36:06,000 --> 00:36:09,000
wote sisi ni kufanya ni sisi ni juu ya safu hii looping,

679
00:36:09,000 --> 00:36:13,000
hivyo sisi kuwa wanandoa wa matanzi kwa hapa, na sisi ni tu kulinganisha na kuona

680
00:36:13,000 --> 00:36:18,000
Je, tuna mechi katika safu yote, mechi katika safu au kitu kama hicho.

681
00:36:18,000 --> 00:36:21,000
Kwa kweli kuendesha programu hii, ikiwa mimi bomba kwenye moja ya vifungo hizi

682
00:36:21,000 --> 00:36:24,000
njia ambayo kucheza alikuwa fired, hivyo kwamba maana mimi tu kuweka

683
00:36:24,000 --> 00:36:31,000
button kuwa X, hivyo sasa kifungo hii itakuwa O, na kadhalika,

684
00:36:31,000 --> 00:36:35,000
na hivyo ndiyo jinsi sisi ni mapya kwa kuingiliana na programu hii moja ukurasa.

685
00:36:35,000 --> 00:36:38,000
>> Tutaweza post code, ili kujisikia huru peruse kwamba,

686
00:36:38,000 --> 00:36:43,000
lakini hebu sasa majadiliano kuhusu baadhi ya programu ambayo ni zaidi kuliko tu ukurasa mmoja.

687
00:36:43,000 --> 00:36:47,000
Kama kusisimua kama Tic TAC Toe ilikuwa, mengi ya programu ndani ya iOS

688
00:36:47,000 --> 00:36:50,000
ni aina ya drill haya mambo chini na skrini nyingi.

689
00:36:50,000 --> 00:36:54,000
dhana ya kwanza kwamba tutaweza haja ya kuzungumza kuhusu ni itifaki,

690
00:36:54,000 --> 00:36:57,000
na itifaki ni tu seti ya mbinu

691
00:36:57,000 --> 00:36:59,000
kwamba wewe unaweza ahadi ya kufafanua.

692
00:36:59,000 --> 00:37:02,000
Kama mimi kuunda hii itifaki mpya na mbinu 2, hii moja kwanza,

693
00:37:02,000 --> 00:37:05,000
kama aina ya kurudi ni batili, mimi kuitwa ni foo.

694
00:37:05,000 --> 00:37:07,000
Inachukua hoja hakuna. Mimi na mwingine mbinu.

695
00:37:07,000 --> 00:37:11,000
Kuirudisha int. Mimi kuitwa ni bar, na inachukua moja hoja.

696
00:37:11,000 --> 00:37:14,000
Hii itifaki zote ni kwamba ni wito SomeProtocol hapa juu,

697
00:37:14,000 --> 00:37:19,000
hii ni seti ya mambo ambayo mtu anaweza kutekeleza.

698
00:37:19,000 --> 00:37:22,000
Mimi si ndani ya itifaki hii alisema nini foo gani.

699
00:37:22,000 --> 00:37:26,000
Badala yake, mimi nina kusema tu unaweza kufafanua foo kama unataka.

700
00:37:26,000 --> 00:37:30,000
Kama mimi nina kujenga mtawala mtazamo au kujenga darasa

701
00:37:30,000 --> 00:37:33,000
Naweza ndani ya kwamba ahadi ya darasa kutekeleza

702
00:37:33,000 --> 00:37:40,000
baadhi ya mbinu hizo, hivyo kwa mfano, kama kusema <SomeProtocol>

703
00:37:40,000 --> 00:37:43,000
hii sasa anasema mimi nina kufanya ahadi na wewe kwamba ndani ya

704
00:37:43,000 --> 00:37:50,000
wa darasa hili mtawala mtazamo nami kuwa ufafanuzi kwa wote foo na bar.

705
00:37:50,000 --> 00:37:52,000
>> Kwa nini ni kwamba manufaa?

706
00:37:52,000 --> 00:37:55,000
mengi ya vipengele ndani ya iOS kuchukua fursa hii,

707
00:37:55,000 --> 00:37:58,000
kubuni muundo kuitwa ujumbe, na nini ujumbe anasema

708
00:37:58,000 --> 00:38:01,000
ni kwamba, kwa mfano, kama nina sanduku Nakala

709
00:38:01,000 --> 00:38:04,000
na kuna baadhi ya matukio ambayo inaweza kusajiliwa ndani ya asilia sanduku langu,

710
00:38:04,000 --> 00:38:07,000
badala ya kujenga matukio tofauti nini siwezi kufanya ni naweza kusema

711
00:38:07,000 --> 00:38:10,000
mjumbe wa sanduku hii Nakala itakuwa baadhi kitu.

712
00:38:10,000 --> 00:38:13,000
Wakati mimi kusema kwamba hii ni mjumbe sasa hiyo ina maana kwamba

713
00:38:13,000 --> 00:38:16,000
kila tukio baadhi ingekuwa fired katika sanduku Nakala

714
00:38:16,000 --> 00:38:18,000
badala ya kuwa na kujiandikisha au kitu kama hicho

715
00:38:18,000 --> 00:38:21,000
ni tu kwenda kuwaita njia ya mjumbe.

716
00:38:21,000 --> 00:38:24,000
Kwa mfano, ndani ya sanduku Nakala yangu nina mbinu kwa ajili ya wakati mimi waandishi

717
00:38:24,000 --> 00:38:27,000
kwamba amefanya kifungo katika haki ya chini,

718
00:38:27,000 --> 00:38:30,000
na hivyo badala ya kusajili tukio handler nini naweza kusema ni

719
00:38:30,000 --> 00:38:34,000
Nakala sanduku, hapa ni kitu ambayo Mimi nataka wewe kuwaita njia juu ya

720
00:38:34,000 --> 00:38:37,000
wakati kila mtu mashinikizo button kufanyika,

721
00:38:37,000 --> 00:38:40,000
na hiyo ina maana kwamba kitu ambayo ina kutekeleza baadhi ya itifaki

722
00:38:40,000 --> 00:38:45,000
kwamba anasema mimi ahadi kufafanua kwamba amefanya kifungo hatua,

723
00:38:45,000 --> 00:38:47,000
kwa sababu kama haina kufafanua kwamba mbinu na vyombo vya habari kufanyika,

724
00:38:47,000 --> 00:38:49,000
basi ni kwenda kuwa na utata.

725
00:38:49,000 --> 00:38:55,000
>> Hebu tuangalie mfano.

726
00:38:55,000 --> 00:38:58,000
Hapa mimi tu na moja Nakala sanduku,

727
00:38:58,000 --> 00:39:04,000
na moja ya mali ya sanduku hii Nakala zaidi ya hapa, upande huu wa kulia ni mjumbe.

728
00:39:04,000 --> 00:39:06,000
Hii ni mali ya darasa.

729
00:39:06,000 --> 00:39:09,000
Nini mimi hapa ni mimi kudhibiti clicked, na mimi dragged kutoka doa hii zaidi hapa

730
00:39:09,000 --> 00:39:13,000
kwa mtawala mtazamo, na kwamba anasema sasa mjumbe wa sanduku hii Nakala

731
00:39:13,000 --> 00:39:18,000
ni kwenda kuwa mtawala mtazamo.

732
00:39:18,000 --> 00:39:20,000
Hiyo ina maana kwamba wakati baadhi vitendo kutokea, badala ya kusajili

733
00:39:20,000 --> 00:39:25,000
tofauti tukio handlers Mimi nataka wewe kuwatuma mjumbe.

734
00:39:25,000 --> 00:39:28,000
Sasa hebu tuangalie mtazamo mtawala wangu.

735
00:39:28,000 --> 00:39:32,000
Ndani ya faili. H nimekuwa alitoa ahadi.

736
00:39:32,000 --> 00:39:36,000
Nimekuwa aliahidi kutekeleza mbinu kadhaa ndani ya itifaki hii

737
00:39:36,000 --> 00:39:38,000
kuitwa UITextFieldDelegate, na tena,

738
00:39:38,000 --> 00:39:42,000
hii ni baadhi tu orodha ya baadhi ya mambo ambayo siwezi kuchagua kutekeleza.

739
00:39:42,000 --> 00:39:46,000
>> Kama mimi kuja hapa katika faili yangu. M, mimi zimetekeleza mmoja kama mbinu.

740
00:39:46,000 --> 00:39:49,000
Nimekuwa kuitwa ni textFieldShouldReturn

741
00:39:49,000 --> 00:39:52,000
kwa sababu hiyo ndiyo ilikuwa inaitwa ndani ya itifaki.

742
00:39:52,000 --> 00:39:57,000
Na sasa wakati mimi waandishi kufanyika kifungo ndani ya shamba kwamba Nakala

743
00:39:57,000 --> 00:40:00,000
hii ni nini kinaendelea kupata walioitwa, hivyo sikuweza kujiandikisha handler tukio hilo.

744
00:40:00,000 --> 00:40:03,000
Mimi kushikamana mjumbe, na wakati wowote tukio hili fired

745
00:40:03,000 --> 00:40:08,000
hii ni njia ambayo inaitwa kupata, hivyo kama mimi kuja hapa kwenye Muhtasari yangu na kukimbia-

746
00:40:08,000 --> 00:40:11,000
wakati hiyo upakiaji tunaweza kuona nini hii gani.

747
00:40:11,000 --> 00:40:13,000
Kwenye screen yangu Ninayo 2.

748
00:40:13,000 --> 00:40:16,000
Nina uwanja huu wa maandishi, na nina studio.

749
00:40:16,000 --> 00:40:19,000
Mimi kusema tu nataka Nakala ya studio hii

750
00:40:19,000 --> 00:40:23,000
kuwa sawa na chochote mtumiaji typed katika ndani ya uwanja maandishi.

751
00:40:23,000 --> 00:40:26,000
Hii mstari unaofuata hapa ni njia tu kwamba mimi nina wito

752
00:40:26,000 --> 00:40:29,000
kwenye shamba Nakala kwamba anasema mimi nataka wewe kujificha keyboard.

753
00:40:29,000 --> 00:40:33,000
Hii ni njia holela kwamba Apple alichagua.

754
00:40:33,000 --> 00:40:38,000
>> Tena, kabla ya mimi alifanya kitu chochote mimi alikuwa na waya kila kitu juu, hivyo mimi kwanza alikuja juu hapa.

755
00:40:38,000 --> 00:40:42,000
Kutoka mtawala view Mimi Drag juu kwa Nakala sanduku.

756
00:40:42,000 --> 00:40:46,000
Mimi basi kwenda, na mimi kuona hapa kwamba naweza kufanya hili shamba Nakala mali

757
00:40:46,000 --> 00:40:49,000
tangu juu hapa nchini mtawala mtazamo nimekuwa defined mali

758
00:40:49,000 --> 00:40:52,000
kwamba ni IBOutlet ya shamba maandishi.

759
00:40:52,000 --> 00:40:55,000
Hii inasema kwamba naweza waya mali hii hadi

760
00:40:55,000 --> 00:40:59,000
kwa shamba asilia katika UI yangu.

761
00:40:59,000 --> 00:41:03,000
Nilipofika bonyeza hii naweza kuanza kuandika.

762
00:41:03,000 --> 00:41:06,000
Sasa kama mimi bonyeza button kufanyika hili ni kwenda kwa moto

763
00:41:06,000 --> 00:41:08,000
tukio kwamba mimi sasa wanaweza kujibu.

764
00:41:08,000 --> 00:41:10,000
Handlers tukio No.

765
00:41:10,000 --> 00:41:13,000
Hayo ni jinsi mimi tu waliitikia kifungo kwamba kufanyika.

766
00:41:13,000 --> 00:41:15,000
Mantiki?

767
00:41:15,000 --> 00:41:20,000
>> Hii si mfano kubuni kwamba-unaweza milele kupata mwenyewe

768
00:41:20,000 --> 00:41:23,000
kujenga itifaki yako mwenyewe, lakini tu kujua kwamba baadhi

769
00:41:23,000 --> 00:41:27,000
tofauti iOS vipengele kujiandikisha matukio katika njia tofauti.

770
00:41:27,000 --> 00:41:29,000
Vifungo, kwa mfano, kutumia IBActions hizo.

771
00:41:29,000 --> 00:41:32,000
Nakala mashamba, kwa upande mwingine, ni kwenda kutumia wajumbe.

772
00:41:32,000 --> 00:41:36,000
Tunaweza kuona na unaweza kuangalia yote ya ndani kuwa juu ya nyaraka.

773
00:41:36,000 --> 00:41:41,000
Kwa njia, kuna kweli tani ya stuff UI kujengwa ndani ya iOS kwa ajili yenu,

774
00:41:41,000 --> 00:41:46,000
hivyo kwa mfano, njia ya mimi kusema kwamba alifanya kufanyika katika haki ya chini

775
00:41:46,000 --> 00:41:48,000
ni mimi kuchaguliwa uwanja huu wa maandishi.

776
00:41:48,000 --> 00:41:50,000
Mimi alikuja juu hapa.

777
00:41:50,000 --> 00:41:53,000
Mimi scrolled chini kidogo kurudi muhimu,

778
00:41:53,000 --> 00:41:56,000
na mimi unaweza kweli kufanya hii rundo zima wa mambo, kama kama nataka kusema kwamba

779
00:41:56,000 --> 00:42:00,000
dharura waomba badala siwezi kufanya hivyo, ambayo ni kabisa random,

780
00:42:00,000 --> 00:42:02,000
na sijui nini kuna kujengwa katika dharura wito kifungo,

781
00:42:02,000 --> 00:42:06,000
lakini kuna, inasema dharura wito kwa herufi ndogo kweli.

782
00:42:06,000 --> 00:42:08,000
Kuna kwenda.

783
00:42:08,000 --> 00:42:12,000
>> Dhahiri kuchunguza yote ya chaguzi hizi tofauti katika iOS.

784
00:42:12,000 --> 00:42:14,000
Maswali yoyote juu ya wajumbe?

785
00:42:14,000 --> 00:42:18,000
Tena, kuvutia tu kubuni muundo kwamba unapaswa kufahamu.

786
00:42:18,000 --> 00:42:22,000
Okay, hebu ijayo kuangalia maoni ya meza.

787
00:42:22,000 --> 00:42:26,000
mtazamo meza kimsingi ni kwamba orodha ya vitu kuwa ni kila mahali katika iOS.

788
00:42:26,000 --> 00:42:29,000
Wakati wewe ni flipping kwa njia zote za mawasiliano yako, wewe kuangalia

789
00:42:29,000 --> 00:42:34,000
ukurasa linatua, na kwamba aina ya orodha ya mambo inaitwa mtazamo meza.

790
00:42:34,000 --> 00:42:37,000
Kutekeleza maoni meza katika iOS ni pretty rahisi.

791
00:42:37,000 --> 00:42:41,000
Badala ya kufanya darasa kwamba anapotoka kwamba UIViewController

792
00:42:41,000 --> 00:42:44,000
kama tumekuwa kufanyika kabla ya sisi tu haja ya kusema kuliko

793
00:42:44,000 --> 00:42:46,000
kila kitu UIViewController haina nataka kufanya,

794
00:42:46,000 --> 00:42:50,000
Mimi kusema kila kitu UITableViewController haina nataka kufanya,

795
00:42:50,000 --> 00:42:54,000
ili tu anaongeza baadhi ya mambo ya nyongeza ambayo ni kabisa kufanyika kwa ajili yetu.

796
00:42:54,000 --> 00:42:58,000
Tunahitaji kufanya kidogo sana na kimsingi kujaza nafasi zilizoachwa wazi ndani ya meza.

797
00:42:58,000 --> 00:43:02,000
>> Ili kuonyesha meza mimi haja ya kujibu baadhi ya maswali.

798
00:43:02,000 --> 00:43:06,000
swali la kwanza mimi haja ya kujibu ni sehemu ngapi ni katika meza?

799
00:43:06,000 --> 00:43:08,000
Wakati wewe ni flipping kupitia programu yako mawasiliano utasikia taarifa kwamba ni aina ya

800
00:43:08,000 --> 00:43:12,000
iliyoandaliwa na Kama, basi una Bs, na una kwamba kidogo ndogo header.

801
00:43:12,000 --> 00:43:14,000
Kila wa wale inaitwa sehemu.

802
00:43:14,000 --> 00:43:16,000
Wewe au anaweza haja hizi.

803
00:43:16,000 --> 00:43:19,000
Jambo la kwanza unahitaji kufanya ni kutekeleza mbinu

804
00:43:19,000 --> 00:43:22,000
kuitwa tableView: numberOfSectionsInTableView.

805
00:43:22,000 --> 00:43:25,000
Hiyo tu anarudi ngapi sehemu una,

806
00:43:25,000 --> 00:43:29,000
hivyo hii inaweza kusema kurudi moja kama una moja kubwa meza mtazamo.

807
00:43:29,000 --> 00:43:33,000
swali la pili kwamba iOS anahitaji kujua ni jinsi gani safu nyingi gani?

808
00:43:33,000 --> 00:43:36,000
Kwa mfano, wewe ni flipping kupitia mtazamo meza.

809
00:43:36,000 --> 00:43:39,000
Una idadi ya kudumu ya nyimbo wewe kuangalia au idadi maalum ya mawasiliano.

810
00:43:39,000 --> 00:43:41,000
Kama wewe ni yangu, bila shaka, si kwamba wengi,

811
00:43:41,000 --> 00:43:44,000
na hivyo ndiyo jinsi iOS anajua jinsi wengi seli ya kuonyesha.

812
00:43:44,000 --> 00:43:46,000
>> Tena, hii inaweza kusema kitu kama kurudi 3.

813
00:43:46,000 --> 00:43:49,000
Meza yangu ina mtazamo safu 3.

814
00:43:49,000 --> 00:43:52,000
Hatimaye, iOS anahitaji kujua nini kila kiini inaonekana kama,

815
00:43:52,000 --> 00:43:54,000
hivyo kile ni kweli kwenda kufanya ni kuwaita njia hii hapa chini,

816
00:43:54,000 --> 00:43:57,000
hii tableView: cellForRowAtIndexPath.

817
00:43:57,000 --> 00:44:01,000
Ni kwenda kuwaita njia hii juu ya kila kiini moja ndani ya meza yako.

818
00:44:01,000 --> 00:44:03,000
Jinsi gani unajua jinsi mara nyingi simu yake?

819
00:44:03,000 --> 00:44:06,000
Naam, ninyi habari ndani ya idadi ya mistari katika sehemu.

820
00:44:06,000 --> 00:44:08,000
Sisi ni kwenda kuwaita hii kila siku juu ya seli zetu,

821
00:44:08,000 --> 00:44:11,000
na ndani ya hii ambapo unaweza kweli kufanya mambo kama

822
00:44:11,000 --> 00:44:16,000
kuweka maandishi au kukuambia nini kuwa buluu kidogo kifungo juu ya upande wa kulia gani.

823
00:44:16,000 --> 00:44:19,000
mfano kwa ajili ya kupata chembechembe hizi, tunakwenda kutumia njia hii

824
00:44:19,000 --> 00:44:22,000
kuitwa dequeueReusableCellWithIdentifier.

825
00:44:22,000 --> 00:44:29,000
>> Lengo-C ni kweli anajulikana sana kwa urefu ridiculous ya majina yao mbinu,

826
00:44:29,000 --> 00:44:32,000
na hii ni kweli kesi nzuri katika mfano uhakika.

827
00:44:32,000 --> 00:44:37,000
Nini njia hii haina ni hii tu anasema mimi nataka wewe nipe kiini.

828
00:44:37,000 --> 00:44:39,000
Tu iOS kitu.

829
00:44:39,000 --> 00:44:41,000
Kama una kitu kama nyimbo 100,000 kwenye iPod yako

830
00:44:41,000 --> 00:44:45,000
nini iOS hataki kufanya ni kutenga seli 100,000,

831
00:44:45,000 --> 00:44:48,000
kwa sababu kama wewe ni katika juu ya orodha yako, je kweli haja kutenga kumbukumbu

832
00:44:48,000 --> 00:44:51,000
kwa hiyo ni kiini 99,000 safu chini?

833
00:44:51,000 --> 00:44:55,000
Hapana, kwa sababu kama wewe ni scrolling unaweza aina ya kutenga kama wewe kwenda pamoja.

834
00:44:55,000 --> 00:44:57,000
Hii inafanywa kwa ajili yenu.

835
00:44:57,000 --> 00:44:59,000
Huwezi kuwa na wasiwasi juu ya mambo ya kijinga kwamba wote utendaji.

836
00:44:59,000 --> 00:45:02,000
Wote wanasema ni wewe piga hii dequeueReusableCellWithIdentifier mbinu,

837
00:45:02,000 --> 00:45:06,000
na hii anasema, sawa, kama unahitaji nitakacho kujenga kiini mpya kwa ajili yenu.

838
00:45:06,000 --> 00:45:09,000
>> Lakini kama wewe ni chini ya meza na ve tayari zimetengwa seli baadhi

839
00:45:09,000 --> 00:45:12,000
saa ya juu ya meza kwamba wewe ni kweli si kwenda haja ya hivi karibuni

840
00:45:12,000 --> 00:45:15,000
Mimi naenda kukupa moja ya wale nyuma badala ya kugawa moja mpya,

841
00:45:15,000 --> 00:45:17,000
na hivyo hii ni nzuri ya utendaji wasiwasi.

842
00:45:17,000 --> 00:45:21,000
Huna kutenga seli mwenyewe.

843
00:45:21,000 --> 00:45:23,000
Hiyo naenda kukupa wewe nyuma kiini.

844
00:45:23,000 --> 00:45:25,000
Ni kwenda na kurudi na wewe kitu kiini.

845
00:45:25,000 --> 00:45:28,000
Mara una kitu kiini unaweza kufanya mambo hayo.

846
00:45:28,000 --> 00:45:32,000
Unaweza kuweka Nakala ya kiini na mali hii inaitwa Nakala studio.

847
00:45:32,000 --> 00:45:36,000
Unaweza kuongeza kuwa mshale juu ya haki au nyingine random stuff

848
00:45:36,000 --> 00:45:41,000
na mali hii nyingine iitwayo accessoryType, na kadhalika na kadhalika.

849
00:45:41,000 --> 00:45:46,000
>> Hebu tuangalie kwa kweli kutekeleza mtazamo meza sasa.

850
00:45:46,000 --> 00:45:49,000
Wakati mimi umba mradi huu

851
00:45:49,000 --> 00:45:53,000
badala ya kusema moja mtazamo maombi mimi kweli alikuja juu hapa

852
00:45:53,000 --> 00:45:57,000
kwa maombi bwana-undani, na hivyo kimsingi hii sambamba na programu pepe

853
00:45:57,000 --> 00:46:01,000
iPad kwa mtazamo meza upande wa kushoto na kisha yaliyomo juu ya haki.

854
00:46:01,000 --> 00:46:07,000
On iPod au iPhone hii ni kwenda yanahusiana na mtazamo moja meza.

855
00:46:07,000 --> 00:46:10,000
Hiyo ambapo mimi got code yangu Starter.

856
00:46:10,000 --> 00:46:13,000
>> Hebu kwanza kuchukua kuangalia storyboard.

857
00:46:13,000 --> 00:46:15,000
Yote hii ilifanyika kwa ajili yangu, kimsingi kuundwa.

858
00:46:15,000 --> 00:46:18,000
Hii bar urambazaji alinionyeshea nini kiini mfano inaweza kuangalia kama,

859
00:46:18,000 --> 00:46:22,000
na mimi unaweza bonyeza mara mbili hii, mabadiliko ya cheo.

860
00:46:22,000 --> 00:46:25,000
Nyingine yoyote UI wasiwasi mimi wanaweza kushughulikia huko.

861
00:46:25,000 --> 00:46:27,000
faili header inaonekana kweli rahisi.

862
00:46:27,000 --> 00:46:30,000
Badala ya kusema hii ni UIViewController tuko sasa akisema hii ni

863
00:46:30,000 --> 00:46:35,000
TableViewController, hivyo tunajua kwamba tunataka wawaite mbinu zote za meza.

864
00:46:35,000 --> 00:46:38,000
Ijayo nataka kujenga mali ambayo inaenda kuwakilisha

865
00:46:38,000 --> 00:46:40,000
mambo ya ndani ya meza yangu.

866
00:46:40,000 --> 00:46:43,000
Meza hii ni ya kwenda kiholela kuonyesha

867
00:46:43,000 --> 00:46:46,000
orodha ya matunda, na hivyo mimi haja ya kuunda baadhi ya safu

868
00:46:46,000 --> 00:46:49,000
ambayo mimi unaweza kuingiza matunda.

869
00:46:49,000 --> 00:46:52,000
Ndani ya utekelezaji wangu faili jambo la kwanza nataka kufanya

870
00:46:52,000 --> 00:46:55,000
ni mimi nataka kuhakikisha mimi initialize hii safu.

871
00:46:55,000 --> 00:46:58,000
>> Mimi alisema alloc init, umba matunda yangu safu,

872
00:46:58,000 --> 00:47:03,000
na mimi nina akiongeza mambo 4 kwa hiyo, moja ambayo ni zaidi kuliko utata 3 nyingine.

873
00:47:03,000 --> 00:47:06,000
Na sasa nina safu ya ukubwa 4.

874
00:47:06,000 --> 00:47:08,000
Sisi ni kutetereka ni juu katika CS50.

875
00:47:08,000 --> 00:47:11,000
Mimi sasa safu ya ukubwa 4.

876
00:47:11,000 --> 00:47:13,000
Sasa mimi nina kwenda kuanza kujibu maswali haya, na kweli,

877
00:47:13,000 --> 00:47:16,000
wakati mimi aliumba hii programu hii yote ilikuwa tayari amefanya kwa ajili yangu.

878
00:47:16,000 --> 00:47:19,000
Sikuwa na kucharaza nje sehemu kadhaa katika mtazamo meza.

879
00:47:19,000 --> 00:47:22,000
Ilikuwa tayari huko, na mimi nina kujaza nafasi zilizoachwa wazi.

880
00:47:22,000 --> 00:47:24,000
Jinsi sehemu ngapi niseme?

881
00:47:24,000 --> 00:47:26,000
Mmoja. Zote kufanyika.

882
00:47:26,000 --> 00:47:28,000
Jinsi safu ngapi niseme?

883
00:47:28,000 --> 00:47:31,000
Naam, mimi kuwa na mstari mmoja kwa kila matunda, hivyo hii kuhesabu

884
00:47:31,000 --> 00:47:34,000
ni mali ya safu yoyote kwamba anasema jinsi kubwa ni nini?

885
00:47:34,000 --> 00:47:36,000
Hiyo ni jinsi wengi safu nina.

886
00:47:36,000 --> 00:47:42,000
Hatimaye, nahitaji kusema nini kila kiini kuangalia kama?

887
00:47:42,000 --> 00:47:46,000
Mimi nina kwenda kusema dequeueReusableCellWithIdentifier.

888
00:47:46,000 --> 00:47:48,000
>> Tena, hii ilikuwa tayari imeandikwa kwa ajili yangu.

889
00:47:48,000 --> 00:47:51,000
Sikuwa na kufanya hili mwenyewe, na nataka kupata nyuma

890
00:47:51,000 --> 00:47:54,000
hii kiini katika eneo hili.

891
00:47:54,000 --> 00:47:57,000
Kumbuka kwamba sisi ni wito njia hii sawa juu ya kila kiini moja,

892
00:47:57,000 --> 00:48:01,000
na hoja hii hapa, hoja hii indexPath,

893
00:48:01,000 --> 00:48:03,000
anasema nini mstari mimi nina in

894
00:48:03,000 --> 00:48:05,000
Nikisema indexPath.row chini hapa

895
00:48:05,000 --> 00:48:09,000
hii itakuwa 0, basi itakuwa 1, basi itakuwa 2, na hii ni hivyo najua

896
00:48:09,000 --> 00:48:11,000
nini kiini Mimi sasa kuonyesha.

897
00:48:11,000 --> 00:48:15,000
Nataka kuweka Nakala ya kiini kutumia mali hii textLabel

898
00:48:15,000 --> 00:48:19,000
kwenda ndani matunda safu yangu na kupata

899
00:48:19,000 --> 00:48:21,000
kitu sambamba na kila mstari.

900
00:48:21,000 --> 00:48:24,000
Kama hii ni kamba, mimi nina sasa kuweka

901
00:48:24,000 --> 00:48:28,000
Nakala mali kwa kamba.

902
00:48:28,000 --> 00:48:30,000
Mimi siwezi kufanya kitu moja nyingine.

903
00:48:30,000 --> 00:48:32,000
Naweza pia kujiandikisha handler tukio juu ya kila moja ya seli,

904
00:48:32,000 --> 00:48:35,000
hivyo wakati mimi bomba kila seli hizi

905
00:48:35,000 --> 00:48:39,000
hii didSelectRowAtIndexPath, hii ni kwenda kuitwa kwa ajili yangu,

906
00:48:39,000 --> 00:48:42,000
hivyo tu na kufafanua hii naweza sasa kushughulikia kile kinachotokea

907
00:48:42,000 --> 00:48:46,000
wakati wewe bomba kiini, na tena, sisi ni kupita katika ambayo kiini tapped

908
00:48:46,000 --> 00:48:50,000
ili tuweze kutumia tena hiyo tukio handler kwa wote wa seli zetu.

909
00:48:50,000 --> 00:48:53,000
>> Tena, hii ni kitu iOS ni kufanya kwa ajili yangu.

910
00:48:53,000 --> 00:48:55,000
Hebu kuonyesha mwingine popup annoying

911
00:48:55,000 --> 00:48:59,000
kwamba tu anasema wewe ilichukua kitu ambapo kwamba kitu

912
00:48:59,000 --> 00:49:04,000
ni kwenda kuwa kitu mfululizo.

913
00:49:04,000 --> 00:49:10,000
Wakati mimi kukimbia hii, mimi naenda kuwa hii nice meza mtazamo

914
00:49:10,000 --> 00:49:14,000
na mstari mmoja kwa kila moja ya matunda haya, na ikiwa mimi bomba moja

915
00:49:14,000 --> 00:49:16,000
ni inaniambia nini kilichotokea.

916
00:49:16,000 --> 00:49:21,000
Mantiki?

917
00:49:21,000 --> 00:49:24,000
Hebu kujenga kidogo kidogo ngumu zaidi ya programu,

918
00:49:24,000 --> 00:49:28,000
kama vile kubonyeza wewe ilichukua nyanya ni.

919
00:49:28,000 --> 00:49:31,000
sehemu nzuri kuhusu storyboarding

920
00:49:31,000 --> 00:49:35,000
ni siyo tu kwenda kusaidia skrini kubuni sisi binafsi,

921
00:49:35,000 --> 00:49:38,000
ni pia kwenda kutusaidia kufunga pamoja programu yetu yote,

922
00:49:38,000 --> 00:49:42,000
hivyo programu ya mwisho tutaweza kuwa jengo ni hii nice habari za michezo msomaji,

923
00:49:42,000 --> 00:49:45,000
na hivyo ni kwenda na skrini nyingi, na hivyo mimi kweli anaweza kuwakilisha

924
00:49:45,000 --> 00:49:48,000
kila moja ya skrini hizi nyingi kwenye storyboard,

925
00:49:48,000 --> 00:49:52,000
na mimi wanaweza zoom nje na kuona programu yangu kutoka ngazi ya juu.

926
00:49:52,000 --> 00:49:55,000
>> Ili kujenga mpya kipengele ndani ya storyboard yangu

927
00:49:55,000 --> 00:49:59,000
ni kweli rahisi ndani ya Builder Interface.

928
00:49:59,000 --> 00:50:01,000
Kama mimi nataka kuongeza mwingine screen hii, kwa mfano,

929
00:50:01,000 --> 00:50:06,000
Naweza kwanza zoom nje kwa zoom Bana kwamba Apple anapenda sana,

930
00:50:06,000 --> 00:50:09,000
na chini hapa kabla mimi kutafuta kifungo

931
00:50:09,000 --> 00:50:12,000
na mimi Drag na kuacha kifungo

932
00:50:12,000 --> 00:50:15,000
kama nataka kujenga screen mpya kweli mimi Drag tu na kuacha

933
00:50:15,000 --> 00:50:19,000
nzima mtazamo mtawala, hivyo kama mimi pick hii, kuvuta ni zaidi ya hapa,

934
00:50:19,000 --> 00:50:23,000
hey, kuna mwingine screen, na hivyo sasa kwa kutumia hiyo storyboard faili

935
00:50:23,000 --> 00:50:26,000
Naweza kuwa na yote ya skrini ndani ya programu yangu, na mimi wanaweza zoom nje

936
00:50:26,000 --> 00:50:28,000
na kuona jinsi kuingiliana.

937
00:50:28,000 --> 00:50:32,000
Haya si kuingiliana bado.

938
00:50:32,000 --> 00:50:36,000
njia ambayo haya skrini 2 kuingiliana ni unaweza kufafanua uhusiano.

939
00:50:36,000 --> 00:50:39,000
Unaweza kusema hii kimsingi screen, wakati waandishi button hii,

940
00:50:39,000 --> 00:50:42,000
Mimi nataka wewe slide juu ya screen hii mpya.

941
00:50:42,000 --> 00:50:44,000
Hiyo ina maana kuna aina hii ya uhusiano kati ya

942
00:50:44,000 --> 00:50:46,000
 screen kwanza na pili screen.

943
00:50:46,000 --> 00:50:49,000
Itabidi kimsingi mshale kutoka kifungo kwamba kwa screen pili

944
00:50:49,000 --> 00:50:53,000
kusema kwamba wakati waandishi hii kifungo hiyo ambapo nataka kwenda.

945
00:50:53,000 --> 00:50:57,000
Tu kama sisi kudhibiti clicked na dragged kufafanua maduka those

946
00:50:57,000 --> 00:51:01,000
tunakwenda kufanya kitu kimoja kufafanua segues haya.

947
00:51:01,000 --> 00:51:05,000
>> Tutaweza kuona mfano kwa kuwa, na kabla ya kweli mpito

948
00:51:05,000 --> 00:51:08,000
kutoka screen moja hadi nyingine iOS ni nzuri kutosha kuwaita njia hii

949
00:51:08,000 --> 00:51:11,000
kuitwa prepareForSegue, na hii ni mahali ambapo tunaweza kuanza

950
00:51:11,000 --> 00:51:14,000
kutuma data kutoka programu moja hadi nyingine.

951
00:51:14,000 --> 00:51:17,000
Katika mfano sisi ni juu ya kuangalia ni mapenzi kimsingi kuruhusu sisi

952
00:51:17,000 --> 00:51:20,000
kuchuja timu ya baseball kwa ligi na mgawanyiko.

953
00:51:20,000 --> 00:51:23,000
Wakati mimi kuchagua ligi, kwa mfano, nataka mpito

954
00:51:23,000 --> 00:51:25,000
screen yangu ijayo ambapo naweza kuonyesha yote ya mgawanyiko

955
00:51:25,000 --> 00:51:27,000
katika kuwa ligi au timu zote tofauti.

956
00:51:27,000 --> 00:51:31,000
Mimi haja ya kutuma kwa kuwa screen nini timu unapaswa kuonyesha.

957
00:51:31,000 --> 00:51:35,000
Ili kufanya hivyo mimi naenda kuchukua faida ya njia hii hapa.

958
00:51:35,000 --> 00:51:39,000
>> Hatimaye, tu hatua random juu ya iOS.

959
00:51:39,000 --> 00:51:41,000
Kama unataka kuhifadhi data kuna jambo hili aitwaye msingi data,

960
00:51:41,000 --> 00:51:44,000
ambayo ni kweli ngumu aina ya kufanya kazi pamoja.

961
00:51:44,000 --> 00:51:47,000
Unaweza pia kutumia SQL kuhifadhi data,

962
00:51:47,000 --> 00:51:51,000
ambayo, tena, ni nzuri lakini aina ya upande ngumu zaidi kufanya kazi pamoja,

963
00:51:51,000 --> 00:51:55,000
lakini pia inasaidia iOS mambo haya kweli cool kuitwa mali orodha,

964
00:51:55,000 --> 00:52:00,000
na orodha ya mali tu ni faili kwamba inawakilisha jozi thamani muhimu.

965
00:52:00,000 --> 00:52:03,000
Unaweza kufafanua orodha ya funguo, na wewe kusema ufunguo hii ni kwenda kuwa safu.

966
00:52:03,000 --> 00:52:06,000
Muhimu Hii ni kwenda kuwa kamba, na kimsingi chochote unaweza kufanya

967
00:52:06,000 --> 00:52:10,000
katika JSON unaweza kufanya ndani ya orodha ya mali,

968
00:52:10,000 --> 00:52:14,000
na hivyo kweli hii nicely inaruhusu sisi kazi na baadhi ya data.

969
00:52:14,000 --> 00:52:18,000
Kwa mfano, nina hii Teams.plist kwamba mimi kuundwa.

970
00:52:18,000 --> 00:52:22,000
Mimi umba mpya plist faili, na mimi siwezi drill chini.

971
00:52:22,000 --> 00:52:26,000
Hii ni kamusi, hii ni kamusi, hizi ni masharti,

972
00:52:26,000 --> 00:52:30,000
na hivyo hii ni nzuri graphical uwakilishi wa hati JSON

973
00:52:30,000 --> 00:52:33,000
au tu ya kuweka jozi ufunguo thamani,

974
00:52:33,000 --> 00:52:37,000
na hivyo hii ni data ambayo mimi itakuwa kufanya kazi na ndani ya programu yangu.

975
00:52:37,000 --> 00:52:40,000
>> Hebu kwanza kuja hapa. Tuna files mengi zaidi sasa.

976
00:52:40,000 --> 00:52:44,000
Lakini hebu kwanza kuja hapa kwenye Muhtasari.

977
00:52:44,000 --> 00:52:48,000
storyboard hapa-kama mimi wanaweza zoom nje-

978
00:52:48,000 --> 00:52:51,000
sasa tunaweza kuona kwamba hii ni mtiririko wa programu yangu.

979
00:52:51,000 --> 00:52:53,000
Mimi kwanza kwenda kuanza kwenye screen hii.

980
00:52:53,000 --> 00:52:55,000
Mimi nina kwenda drill chini screen hii,

981
00:52:55,000 --> 00:52:58,000
na mimi nina kwenda drill chini screen hii, na tunaweza kuona hapa kwamba kama mimi aina ya

982
00:52:58,000 --> 00:53:04,000
hoja moja ya hizi kuzunguka tuna hizi mishale inaenda hapa na hapa,

983
00:53:04,000 --> 00:53:08,000
na njia ya mimi kufafanua kwamba mshale ilikuwa kama mimi zoom katika kidogo,

984
00:53:08,000 --> 00:53:12,000
na kama mimi kuja juu na mtawala mtazamo huu,

985
00:53:12,000 --> 00:53:16,000
na hapa ni kiini, na mimi nataka kusema kwamba wakati bomba kiini

986
00:53:16,000 --> 00:53:18,000
Mimi nataka wewe slide juu ya screen mwingine.

987
00:53:18,000 --> 00:53:21,000
Naweza tu kushikilia chini ya udhibiti,

988
00:53:21,000 --> 00:53:26,000
kitabu juu ya kidogo kidogo, kushikilia chini ya udhibiti, Drag hii kiini juu na basi kwenda.

989
00:53:26,000 --> 00:53:30,000
>> Na zaidi ya hapa tunasema nini mpito kwamba unataka kutumia?

990
00:53:30,000 --> 00:53:32,000
Je, unataka kutumia kitu slide kwamba wito kushinikiza?

991
00:53:32,000 --> 00:53:34,000
Je, unataka slide juu kutoka chini?

992
00:53:34,000 --> 00:53:36,000
Hiyo inaitwa modal.

993
00:53:36,000 --> 00:53:40,000
Na mara moja mimi bonyeza moja ya hizi, ni kwenda kuteka hii arrow kwa ajili yangu,

994
00:53:40,000 --> 00:53:44,000
na hiyo ina maana kwamba Nimekuwa kwa kweli kubebwa kile kinachotokea wakati Nakaza hii kifungo graphically.

995
00:53:44,000 --> 00:53:48,000
Sikuweza kuandika code yoyote kwa kweli slide kutoka screen 00:59 ijayo.

996
00:53:48,000 --> 00:53:51,000
Mimi defined hii kuibua ndani ya Builder Interface.

997
00:53:51,000 --> 00:53:55,000
Kama mimi bonyeza mshale huu, tunaweza kuona kwamba mimi alitoa jambo hili jina.

998
00:53:55,000 --> 00:53:59,000
Mimi kuitwa ni showDivisions, na hii ni ili niweze kujua

999
00:53:59,000 --> 00:54:03,000
kile cha mpito ni karibu kutokea, na tutaweza kuona nini katika tu sec.

1000
00:54:03,000 --> 00:54:06,000
Hiyo ni jinsi nimekuwa wired up skrini tofauti katika programu yangu.

1001
00:54:06,000 --> 00:54:09,000
Kama hili walikuwa kifungo, kwa mfano, badala ya mtazamo meza,

1002
00:54:09,000 --> 00:54:11,000
Mimi inaweza kudhibiti bonyeza button, Drag juu ya screen ijayo,

1003
00:54:11,000 --> 00:54:16,000
na kwamba ni jinsi gani naweza kufanya urambazaji kwamba njia.

1004
00:54:16,000 --> 00:54:19,000
>> Kweli haraka, kama sisi kuja katika MasterViewController,

1005
00:54:19,000 --> 00:54:22,000
tena, tuko tu kwenda kufafanua orodha ya mambo

1006
00:54:22,000 --> 00:54:26,000
kwamba itakuwa visas katika mtazamo meza.

1007
00:54:26,000 --> 00:54:29,000
Hapa mimi kusema mimi nataka kuchukua kwamba faili plist,

1008
00:54:29,000 --> 00:54:32,000
na mimi nataka wewe mzigo juu katika kamusi,

1009
00:54:32,000 --> 00:54:35,000
na mara moja tu na kwamba kamusi, mimi naenda kujibu maswali hayo tena.

1010
00:54:35,000 --> 00:54:37,000
Hapa ni sehemu kadhaa.

1011
00:54:37,000 --> 00:54:41,000
Mmoja, kuna mstari mmoja kwa kila ligi, na maandishi ya kila kiini

1012
00:54:41,000 --> 00:54:46,000
wanapaswa kuwa ama moja kwanza, ligi ya kwanza, ligi ya pili, na kadhalika.

1013
00:54:46,000 --> 00:54:51,000
Mwisho, mimi naenda kutumia njia hii ya kuwa sisi tu kuona kuitwa prepareForSegue,

1014
00:54:51,000 --> 00:54:54,000
na hii ni njia ambayo inaenda kuwa fired wakati mimi bonyeza

1015
00:54:54,000 --> 00:54:57,000
juu ya moja ya safu hizo na kwa hiyo inleda kwamba mpito

1016
00:54:57,000 --> 00:54:59,000
kwamba mimi kuanzisha na mishale.

1017
00:54:59,000 --> 00:55:02,000
Hii ni kusema kwamba siwezi kuwa na nyingi

1018
00:55:02,000 --> 00:55:05,000
mahusiano kutoka screen moja na nyingine.

1019
00:55:05,000 --> 00:55:08,000
Kama mimi na vifungo 2 na kifungo kila inachukua wewe screen mbalimbali

1020
00:55:08,000 --> 00:55:10,000
Mimi naenda kuwa segues 2, 1 kwa kila kifungo.

1021
00:55:10,000 --> 00:55:14,000
Lakini prepareForSegue hii ni mara ya pili, kwenda kuwa reused

1022
00:55:14,000 --> 00:55:17,000
kwa kila moja ya mahusiano mbalimbali, hivyo hiyo ina maana kwamba mimi haja njia

1023
00:55:17,000 --> 00:55:21,000
ya kutambua kama vyombo vya habari kifungo kwanza au vyombo vya habari button pili.

1024
00:55:21,000 --> 00:55:25,000
>> Kumbuka wakati mimi alitoa kwamba segue jina, hii showDivisions,

1025
00:55:25,000 --> 00:55:29,000
hiyo ni jinsi mimi sasa kujua kwamba hii ni segue kwamba alikuwa ulioamilishwa.

1026
00:55:29,000 --> 00:55:32,000
Yote nataka kufanya ni mimi nataka kusema

1027
00:55:32,000 --> 00:55:35,000
Mimi nataka kufikiri nini mimi tu hit,

1028
00:55:35,000 --> 00:55:38,000
na hivyo kupata kwamba, naweza kusema mimi nataka indexPath kwa safu ya kuchaguliwa,

1029
00:55:38,000 --> 00:55:42,000
kumbuka indexPath tu anasema ambapo mimi tu clicked,

1030
00:55:42,000 --> 00:55:47,000
na kisha Mimi nataka kusema nataka kufikiri ambapo mimi naenda.

1031
00:55:47,000 --> 00:55:50,000
DestinationViewController hii, hiyo ni mali ya segue.

1032
00:55:50,000 --> 00:55:53,000
Hiyo screen nitakacho,

1033
00:55:53,000 --> 00:55:56,000
hivyo najua kwamba screen nitakacho inaitwa DivisionsViewController

1034
00:55:56,000 --> 00:55:59,000
kwa sababu mimi umba kwamba darasa,

1035
00:55:59,000 --> 00:56:02,000
na hivyo sasa kama mimi kusema d.divisions

1036
00:56:02,000 --> 00:56:06,000
Mimi sasa kuweka mali ya mtawala mtazamo mimi nina kuhusu kwenda.

1037
00:56:06,000 --> 00:56:10,000
Hii ni jinsi mimi nina kutuma data kutoka screen moja na screen mwingine.

1038
00:56:10,000 --> 00:56:13,000
>> Kuangalia tu DivisionsViewController hii

1039
00:56:13,000 --> 00:56:16,000
unaweza kuona hapa kwamba katika faili. h

1040
00:56:16,000 --> 00:56:20,000
kuna mgawanyiko mali, na kwamba ni nini mimi kimsingi populating,

1041
00:56:20,000 --> 00:56:25,000
hivyo kwamba ni jinsi gani mimi kujua kwamba mimi nina kuonyesha mgawanyiko sambamba na

1042
00:56:25,000 --> 00:56:28,000
ligi hiyo mimi clicked, na tena,

1043
00:56:28,000 --> 00:56:31,000
halisi meza mtazamo inaonekana pretty kiasi sawa, tu kujibu those

1044
00:56:31,000 --> 00:56:34,000
3 rahisi maswali kama vile kutambua

1045
00:56:34,000 --> 00:56:37,000
kile kinachotokea wakati hoja ya screen ijayo.

1046
00:56:37,000 --> 00:56:40,000
Michache tu ya mambo mengine hapa.

1047
00:56:40,000 --> 00:56:43,000
Utaona saa ya juu hapa kwamba badala ya kusema ni pamoja na #

1048
00:56:43,000 --> 00:56:45,000
Mimi sasa akisema # kuagiza.

1049
00:56:45,000 --> 00:56:47,000
Hii ni kitu Lengo-C.

1050
00:56:47,000 --> 00:56:52,000
kuagiza kimsingi ni toleo nicer ya pamoja,

1051
00:56:52,000 --> 00:56:57,000
na kwa mfano, tunahitaji kujua kile darasa hili ni,

1052
00:56:57,000 --> 00:57:00,000
hivyo siwezi kusema tu DivisionsViewController.

1053
00:57:00,000 --> 00:57:05,000
Kama hatukuwa hashtag ndani standardio.c ya faili wetu c.

1054
00:57:05,000 --> 00:57:07,000
compiler hakuwa na wazo gani printf ilikuwa.

1055
00:57:07,000 --> 00:57:12,000
Vile vile, kama mimi si kuagiza DivisionsViewController

1056
00:57:12,000 --> 00:57:16,000
compiler kweli ana sijui nini DivisionsViewController ni.

1057
00:57:16,000 --> 00:57:19,000
Tu kuhakikisha kwamba ndani ya mafaili yako tofauti. M wewe kuhakikisha kuagiza

1058
00:57:19,000 --> 00:57:25,000
sambamba. h files ili compiler anajua nini kinaendelea.

1059
00:57:25,000 --> 00:57:31,000
>> Hatimaye, nini Apple hatimaye gani ni kuonyesha baadhi ya data kwa kutumia mtazamo mtandao,

1060
00:57:31,000 --> 00:57:35,000
na hivyo mtazamo mtandao ni kitu ambayo unaweza embed

1061
00:57:35,000 --> 00:57:37,000
kidogo ya mtandao browser ndani ya programu yako.

1062
00:57:37,000 --> 00:57:40,000
Wote unahitaji kufanya ni ugavi URL kwa mtandao browser yako,

1063
00:57:40,000 --> 00:57:43,000
hivyo nataka kwenda mlb.mlb.com,

1064
00:57:43,000 --> 00:57:46,000
na hii ni jinsi gani naweza kupata ukurasa wa nyumbani kwa kila timu,

1065
00:57:46,000 --> 00:57:49,000
na hivyo kwa kupita katika URL hii

1066
00:57:49,000 --> 00:57:52,000
mtazamo mtandao wanaweza kuonyesha hii kwa ajili yangu, na mimi unaweza kuvinjari kote,

1067
00:57:52,000 --> 00:58:01,000
na simulator ni katika matumizi na kwamba moja.

1068
00:58:01,000 --> 00:58:03,000
Sasa hii alifika kutoka plist yangu.

1069
00:58:03,000 --> 00:58:07,000
Kama mimi bonyeza hii hii pia alifika kutoka plist yangu, na sliding hili kubebwa

1070
00:58:07,000 --> 00:58:09,000
na kufafanua segues hizo.

1071
00:58:09,000 --> 00:58:12,000
Mimi bonyeza hii na moja zaidi,

1072
00:58:12,000 --> 00:58:15,000
na sasa hapa ni UIWebView yangu, hivyo tu kama kwamba

1073
00:58:15,000 --> 00:58:19,000
hapa ni tovuti kwa ajili ya URL kwamba mimi tu iliyoingia,

1074
00:58:19,000 --> 00:58:21,000
na sikuwa na kushughulikia chochote mambo.

1075
00:58:21,000 --> 00:58:24,000
Hii ni jinsi ya kuonyesha ukurasa wa mtandao.

1076
00:58:24,000 --> 00:58:27,000
Mambo kama button hii nyuma hapa pia niliopewa

1077
00:58:27,000 --> 00:58:33,000
kabisa kwa sababu nimekuwa bure defined mahusiano haya kwa kutumia segues.

1078
00:58:33,000 --> 00:58:37,000
>> Maswali yoyote? Yeah.

1079
00:58:37,000 --> 00:58:40,000
[Mwanafunzi] Basi wakati matumizi alloc, wewe kamwe kuwa na kitu chochote bure?

1080
00:58:40,000 --> 00:58:43,000
Hasa, wakati wewe piga alloc na init huna huru yake.

1081
00:58:43,000 --> 00:58:46,000
IOs ni kwenda kushughulikia yote ya kwamba kwa ajili yenu.

1082
00:58:46,000 --> 00:58:51,000
Ni ajabu, na wewe si kuvunja sheria yoyote. Yeah.
