1
00:00:00,000 --> 00:00:07,880

2
00:00:07,880 --> 00:00:09,800
>> RHED SHI: Karibu
kuona CS50 semina -

3
00:00:09,800 --> 00:00:11,630
Kuanzishwa kwa iOS.

4
00:00:11,630 --> 00:00:13,290
Kuwashukuru wote kwa kuja.

5
00:00:13,290 --> 00:00:16,610
Natumaini wewe ni tu kama msisimko
kama mimi ni juu ya iOS.

6
00:00:16,610 --> 00:00:22,300
Mwaka jana, mimi alichukua CS50 kama sophomore,
na mimi kimsingi kujifunza iOS kwa yangu

7
00:00:22,300 --> 00:00:23,490
mwisho wa mradi.

8
00:00:23,490 --> 00:00:26,350
Na ilikuwa pretty -

9
00:00:26,350 --> 00:00:30,530
vizuri, haikuwa rahisi, lakini kuna
kura ya msaada tutorials online.

10
00:00:30,530 --> 00:00:33,760
Na mimi kwa kweli matumaini yetu kuwa na hii
semina, mimi nitakupa guys kichwa

11
00:00:33,760 --> 00:00:36,750
kuanza iOS maendeleo

12
00:00:36,750 --> 00:00:40,490
>> Hivyo, katika suala la iOS maendeleo,
kuna mambo mawili muhimu sisi

13
00:00:40,490 --> 00:00:42,090
unataka kufunika leo.

14
00:00:42,090 --> 00:00:43,290
Kwanza, lugha -

15
00:00:43,290 --> 00:00:46,650
lugha ni kwenda kuwa katika
Lengo-C. Tutaweza kweli kusikia

16
00:00:46,650 --> 00:00:47,750
kitu kweli kusisimua.

17
00:00:47,750 --> 00:00:51,500
Kwa hiyo, unaweza kujiunga na Apple zima
jamii ya watengenezaji na kujenga baadhi ya

18
00:00:51,500 --> 00:00:52,940
kweli kutisha programu.

19
00:00:52,940 --> 00:00:58,670
>> Pia, iOS 7 ni nzuri, hopefully,
kwa baadhi yenu.

20
00:00:58,670 --> 00:01:01,130
Lakini ni utata, najua.

21
00:01:01,130 --> 00:01:05,349
Na hasa, nini nataka kufanya ni mwongozo
ninyi kwa njia ya Lengo-C, na pia

22
00:01:05,349 --> 00:01:10,650
Xcode, ambayo ni jumuishi
maendeleo ya mazingira kuwa wewe utakuwa

23
00:01:10,650 --> 00:01:13,460
kufanya kazi kwa ajili ya iOS.

24
00:01:13,460 --> 00:01:19,140
>> Na hivyo, kama neno juu ya Malengo ya-C.
Kimsingi, ni sawa na halisi kama C,

25
00:01:19,140 --> 00:01:22,790
lakini kwa mambo mengine mengi.

26
00:01:22,790 --> 00:01:27,710
Na hivyo, madhubuti zaidi, ni kweli
super-seti ya C. Hivyo kitu chochote

27
00:01:27,710 --> 00:01:32,280
wanaweza kufanya katika C sasa hivi, ambayo ni
kimsingi kama pset 0 kwa njia ya 6, wewe

28
00:01:32,280 --> 00:01:34,170
wanaweza kufanya katika Malengo ya-C.

29
00:01:34,170 --> 00:01:38,620
>> Hivyo, wala kuhisi hofu juu ya hii mpya
lugha kwamba utaenda kujifunza.

30
00:01:38,620 --> 00:01:42,120
Umefanya tayari kufunikwa mengi ya hayo,
kwa sababu umefanya yote kufanyika C zamani hii

31
00:01:42,120 --> 00:01:45,880
muhula, ila sasa utaenda
kuwa na mengi zaidi kufanya kazi pamoja.

32
00:01:45,880 --> 00:01:49,270
Na mimi nina kwenda tu kwa kusababisha wewe kupitia
mifano michache kuonyesha baadhi

33
00:01:49,270 --> 00:01:53,920
ya tofauti muhimu kwamba nimeona walikuwa
wakati kwa kweli muhimu mimi kujifunza

34
00:01:53,920 --> 00:01:57,180
Lengo-C mwaka jana.

35
00:01:57,180 --> 00:02:00,910
>> Vizuri kwa kweli, hivyo, hatua nyingine
ni, Lengo-C ni, ni wazi,

36
00:02:00,910 --> 00:02:02,200
kitu-oriented.

37
00:02:02,200 --> 00:02:06,340
Na tutaweza kujadili kidogo
kuhusu nini maana ya baadaye.

38
00:02:06,340 --> 00:02:11,340
Kimsingi, ni kama jinsi kazi na
structs katika pset hii iliyopita, na

39
00:02:11,340 --> 00:02:13,360
nodes na sawa nyingine
mambo kama hayo.

40
00:02:13,360 --> 00:02:17,110
Ila, katika Malengo ya-C, kila kitu ni
kitu, na wewe ni kwenda kuwa

41
00:02:17,110 --> 00:02:20,720
kupita karibu na kuyatumia kwa vitu
badala ya maadili wenyewe.

42
00:02:20,720 --> 00:02:25,050
Kwa hiyo, ni kitu muhimu
kukumbuka.

43
00:02:25,050 --> 00:02:29,140
>> Hivyo, kwa nini sio sisi kuanza na chache
tofauti katika syntax kati ya C na

44
00:02:29,140 --> 00:02:30,540
Lengo-C?

45
00:02:30,540 --> 00:02:38,310
Mimi nataka kuonyesha # ni pamoja na, wewe
kujua, kiwango io.h katika C na C + +, na

46
00:02:38,310 --> 00:02:44,030
Lengo-C toleo la kwamba, ambayo
ni # kuagiza, na kisha aina fulani ya

47
00:02:44,030 --> 00:02:44,790
header file.

48
00:02:44,790 --> 00:02:48,165
Katika kesi hiyo, itakuwa UIKit,
unajua, kufyeka UIKit.h.

49
00:02:48,165 --> 00:02:53,560
Pia inaweza kuwa, unajua, MKMapview
wewe kufyeka MKMapview.h kama unataka

50
00:02:53,560 --> 00:02:56,370
kufanya, kama, ramani ndani ya programu yako.

51
00:02:56,370 --> 00:02:57,110
Mambo sawa kama hiyo.

52
00:02:57,110 --> 00:03:01,250
>> Kwa hiyo, jambo muhimu ni pamoja na
sasa imebadilika kuagiza.

53
00:03:01,250 --> 00:03:04,340
Lakini wazo bado.

54
00:03:04,340 --> 00:03:10,460
Wewe ni kwenda kuwa kuagiza aina fulani
ya kichwa file katika mpango wako.

55
00:03:10,460 --> 00:03:14,550
>> Mimi pia nataka kuonyesha tofauti
kati ya printf na NSLog.

56
00:03:14,550 --> 00:03:19,760
Hata hivyo, kama sisi alisema mapema, Lengo-C
ni kali super-seti ya

57
00:03:19,760 --> 00:03:22,800
C, ambayo ina maana kwamba printf ipo
katika Malengo ya-C, pia.

58
00:03:22,800 --> 00:03:24,340
Lakini, watu wengi hawana kutumia.

59
00:03:24,340 --> 00:03:28,245
Watu wengi kutumia hii NSLog kwa sababu
inakupa muda muhuri, na tutaweza kuona

60
00:03:28,245 --> 00:03:29,780
katika hatua ya baadaye.

61
00:03:29,780 --> 00:03:33,560
Lakini, ni kwa ujumla muhimu zaidi
njia ya magazeti nje vigezo.

62
00:03:33,560 --> 00:03:38,220
>> Na pia nataka kuonyesha kwamba
NSLog inachukua katika sawa tu

63
00:03:38,220 --> 00:03:41,650
placeholder maadili kama printf gani -

64
00:03:41,650 --> 00:03:45,900
hivyo% d ni kwa int,
% F ni kwa kuelea.

65
00:03:45,900 --> 00:03:49,750
Hata hivyo, mimi unataka kuonyesha
huyu wa mwisho sana -

66
00:03:49,750 --> 00:03:52,960
NSLog% katika ishara -

67
00:03:52,960 --> 00:03:55,390
kwamba ni placeholder kwa kitu.

68
00:03:55,390 --> 00:04:01,160
Na kama nilivyosema awali, Lengo-C mikataba
pretty much zaidi katika vitu,

69
00:04:01,160 --> 00:04:05,020
na hivyo hii itakuwa kuja katika matumizi ya wakati
unataka magazeti nje, pengine, labda

70
00:04:05,020 --> 00:04:08,390
NSArray, au NSDictionary,
au NSString.

71
00:04:08,390 --> 00:04:13,750
>> Kwa hiyo, pia, taarifa kwamba, katika NSLog wetu
taarifa, tuna katika ishara mbele

72
00:04:13,750 --> 00:04:15,380
ya quotation -

73
00:04:15,380 --> 00:04:20,769
kwamba ni kwa ishara ya kuwa masharti, sasa,
katika Malengo ya-C ni vitu.

74
00:04:20,769 --> 00:04:23,310
Wao ni tena nyota tu char.

75
00:04:23,310 --> 00:04:25,530
Wao ni vitu na ni
kutibiwa kama vile.

76
00:04:25,530 --> 00:04:28,690
>> Hivyo, ni muhimu kwamba wakati
matumizi ya NSLog inachukua katika NS

77
00:04:28,690 --> 00:04:32,580
kamba, ambayo ina maana kwamba itabidi
ni pamoja na katika mbele yako

78
00:04:32,580 --> 00:04:34,270
quotation alama.

79
00:04:34,270 --> 00:04:38,290
Na kwamba ni kwa nini unaweza kuona, hapa, katika yote ya
kazi yangu wito kwa hii NSLog, mimi

80
00:04:38,290 --> 00:04:42,400
kuwa katika mbele ya quotes, hata
ingawa% d na% f ni

81
00:04:42,400 --> 00:04:45,200
wote ni sawa kutoka C.

82
00:04:45,200 --> 00:04:47,930
>> Maswali yoyote hadi sasa?

83
00:04:47,930 --> 00:04:50,920
Nitajaribu kwenda kwa njia hii haraka ili
kwamba tunaweza kuwa na muda zaidi wa kufanya kazi

84
00:04:50,920 --> 00:04:55,210
na Xcode na Lengo-C, hivyo
kwamba guys wanaweza kupata zaidi

85
00:04:55,210 --> 00:04:57,630
familiar nayo.

86
00:04:57,630 --> 00:05:01,900
>> Next, nataka kuonyesha kitu
conceptually muhimu.

87
00:05:01,900 --> 00:05:05,130
Hivyo, katika C, mambo mengi ni kazi.

88
00:05:05,130 --> 00:05:06,280
Sisi kufanya kazi simu.

89
00:05:06,280 --> 00:05:10,190
Sisi kutangaza kazi kwa njia hii, kwa
kurudi Aina ya kwanza, basi

90
00:05:10,190 --> 00:05:13,570
kazi jina, mabano, na kisha
hoja chochote na aina ya

91
00:05:13,570 --> 00:05:15,590
hoja hizi tunataka kupitisha in

92
00:05:15,590 --> 00:05:19,970
Na Lengo-C, kwa sababu kila kitu
ni kitu au darasa -

93
00:05:19,970 --> 00:05:23,970
hivyo darasa na kitu ni suala mawili ambayo
ni zaidi ya sawa na kila mmoja,

94
00:05:23,970 --> 00:05:28,270
ili nipate matumizi yao kwa kubadilishana
katika semina hiyo.

95
00:05:28,270 --> 00:05:34,090
>> Lakini, utaona kwamba tuna mbinu katika
Lengo-C badala ya kazi.

96
00:05:34,090 --> 00:05:36,390
Na mbinu ni ya vitu.

97
00:05:36,390 --> 00:05:38,950
Hivyo tu kama, labda kuchukua
kwa mfano, node -

98
00:05:38,950 --> 00:05:40,250
aina yetu [inaudible]

99
00:05:40,250 --> 00:05:44,390
node kutoka pset 6 au 5 -

100
00:05:44,390 --> 00:05:49,590
tuna neno, mali,
au node pointer ijayo.

101
00:05:49,590 --> 00:05:53,880
Mbinu ni kazi ndani ya tu
baadhi ya aina ya muundo.

102
00:05:53,880 --> 00:05:57,510
>> Hivyo, katika kesi hii, muundo itakuwa
kitu, na kisha ni njia

103
00:05:57,510 --> 00:05:59,260
kitu ambacho ni kitu.

104
00:05:59,260 --> 00:06:02,650
Na hii ni jinsi gani kutangaza,
aina ya, mbinu.

105
00:06:02,650 --> 00:06:07,990
Ungependa kuanza na, tena, kurudi
aina - hivyo, mimi alijaribu rangi

106
00:06:07,990 --> 00:06:12,990
maneno msimbo muhimu hapa ili guys
unaweza kuona, angalau, formatting

107
00:06:12,990 --> 00:06:17,650
yanayofanana kati ya kazi
maazimio na njia maazimio.

108
00:06:17,650 --> 00:06:21,990
Hivyo, kuanza kwa, unajua, kurudi
aina - katika kesi hii, ni safu, au

109
00:06:21,990 --> 00:06:23,910
NSArray pointer -

110
00:06:23,910 --> 00:06:26,710
na kisha una njia hii.

111
00:06:26,710 --> 00:06:30,900
Na kisha, nini kuvutia hapa ni
kwamba badala ya kuwa na mabano, sisi

112
00:06:30,900 --> 00:06:32,900
na colons haya.

113
00:06:32,900 --> 00:06:38,450
Na kisha, mbele ya hoja yetu, sisi
kuweka, tena, katika mabano ya aina

114
00:06:38,450 --> 00:06:39,370
wa hoja yetu.

115
00:06:39,370 --> 00:06:43,160
>> Hiyo, sasa hivi mimi nina kujaribu kufanya
kulinganisha kati ya, unajua, n na

116
00:06:43,160 --> 00:06:45,450
idadi, kwa sababu wao ni
wote kama ints.

117
00:06:45,450 --> 00:06:49,580
Na kisha, mtu mwingine
ni ya aina NSUInteger.

118
00:06:49,580 --> 00:06:56,390
Na kisha, kwa lengo-C, wakati
wanataka kuwa na hoja nyingi katika

119
00:06:56,390 --> 00:07:00,030
njia yako kifungu, wewe, aina ya,
baina yao nje aina ya kama hii -

120
00:07:00,030 --> 00:07:03,790
Mimi nina uhakika kabisa jinsi ya kueleza hayo,
lakini hii ni mfano mzuri wa jinsi

121
00:07:03,790 --> 00:07:06,530
unaweza kuwa na hoja nyingi huko.

122
00:07:06,530 --> 00:07:10,360
>> Unaweza, bila shaka, haki kabisa
kupuuza andArray koloni NSArray

123
00:07:10,360 --> 00:07:13,240
safu kama alitaka tu njia ya
kwamba inachukua katika hoja moja.

124
00:07:13,240 --> 00:07:13,677
Ndiyo, swali.

125
00:07:13,677 --> 00:07:18,701
>> Watazamaji: Je, wote NSUInteger na
NSArray hoja ambayo yanaweza kuchukuliwa katika

126
00:07:18,701 --> 00:07:21,530
ndani ya NSArray?

127
00:07:21,530 --> 00:07:22,060
>> RHED SHI: Ndiyo.

128
00:07:22,060 --> 00:07:23,400
Kwa hiyo, napenda kueleza.

129
00:07:23,400 --> 00:07:23,790
Kwa hiyo, ndiyo.

130
00:07:23,790 --> 00:07:30,260
Hivyo, swali ni NSUInteger na
NSArray * aina ya hoja,

131
00:07:30,260 --> 00:07:31,570
na kwamba ni sahihi.

132
00:07:31,570 --> 00:07:35,700
Basi, wewe siku zote wanataka bayana nini
aina ya hoja yako ni.

133
00:07:35,700 --> 00:07:41,570
Na hapa, mimi nina kujaribu kuanzisha wewe
baadhi ya syntax na vocab ya

134
00:07:41,570 --> 00:07:45,910
Lengo-C, hivyo wale ni aina halisi
kuwa wewe utakuwa kushughulika na.

135
00:07:45,910 --> 00:07:48,970
>> Na kama wewe utakuwa taarifa, arrays
tena, aina ya,

136
00:07:48,970 --> 00:07:50,780
rahisi bracket mambo.

137
00:07:50,780 --> 00:07:52,060
Wao ni vitu.

138
00:07:52,060 --> 00:07:56,700
Pamoja na kwamba, kama sisi kwenda kwenye ijayo
slide, tunaweza kuona kwamba tunaweza

139
00:07:56,700 --> 00:08:02,510
ngumu-code NSArray katika Malengo ya-C na
tu katika ishara mbele ya

140
00:08:02,510 --> 00:08:04,190
mabano.

141
00:08:04,190 --> 00:08:08,650
Mimi si, kwa kweli, uhakika kabisa kama
Mimi syntactically ngumu-coded safu

142
00:08:08,650 --> 00:08:16,020
usahihi kwa C version, lakini hiyo ni
wanatakiwa kuwa katika C safu.

143
00:08:16,020 --> 00:08:19,760
>> Kwa hiyo, hili ni jinsi gani, unajua,
labda kutumia kazi au

144
00:08:19,760 --> 00:08:21,990
mbinu kwamba sisi aliumba mapema.

145
00:08:21,990 --> 00:08:22,250
Haki?

146
00:08:22,250 --> 00:08:25,340
Kwa hiyo, hili ni mahali ambapo sisi kutangaza wetu
kazi na njia yetu.

147
00:08:25,340 --> 00:08:28,020
Na sasa sisi wanataka kuwatumia katika
mpango wetu, na hii ni

148
00:08:28,020 --> 00:08:29,450
jinsi gani tunataka kufanya hivyo.

149
00:08:29,450 --> 00:08:32,400
Hivyo, katika C, ingekuwa, unajua,
labda, bool b, na kuweka kwa

150
00:08:32,400 --> 00:08:36,549
sawa kazi, na kisha
kupita katika hoja.

151
00:08:36,549 --> 00:08:39,190
>> Katika Lengo-C, ni pretty
sana kitu kimoja.

152
00:08:39,190 --> 00:08:43,370
Una NSArray * my_array, na ni
kwenda sawa - sasa, tu

153
00:08:43,370 --> 00:08:47,460
tofauti hapa ni jambo hili kitu,
ambayo nimekuwa yalionyesha katika njano, na

154
00:08:47,460 --> 00:08:51,180
kama unaweza kuona, katika C, kuna
hakuna njano nyingine neno.

155
00:08:51,180 --> 00:08:54,170
Na ni kwa sababu njia ni
na kitu fulani.

156
00:08:54,170 --> 00:08:59,800
Hivyo ndiyo sababu mimi haja ya kuwa na kitu
kwamba, aina ya, wito njia hii juu ya

157
00:08:59,800 --> 00:09:04,360
Idadi ya sifuri, na kisha
NSArray, b, c, d.

158
00:09:04,360 --> 00:09:05,350
Maswali yoyote juu ya hilo?

159
00:09:05,350 --> 00:09:12,190
>> Tutaweza kuona dhana hizi katika hatua
pretty hivi karibuni wakati sisi kwenda katika demo.

160
00:09:12,190 --> 00:09:13,400
OK.

161
00:09:13,400 --> 00:09:17,170
Sasa, nataka kuzungumza kidogo kwa ufupi
kuhusu Xcode 5, ambayo ni

162
00:09:17,170 --> 00:09:21,160
mazingira shirikishi ya maendeleo
kuwa wewe utakuwa kufanya kazi pamoja.

163
00:09:21,160 --> 00:09:26,160
Najua mengi ya wewe, au baadhi yenu,
hawana Macs, ambayo ni tatizo

164
00:09:26,160 --> 00:09:30,490
kwa sababu Xcode si inapatikana
kwa Windows na PC.

165
00:09:30,490 --> 00:09:32,785
Je, si kuuliza kwa nini, lakini pengine -

166
00:09:32,785 --> 00:09:33,730
yeah, ushirika.

167
00:09:33,730 --> 00:09:35,290
Chochote.

168
00:09:35,290 --> 00:09:39,360
Lakini anyway, hivyo, mimi kuomba msamaha kama baadhi ya
huna na kushusha aina fulani ya

169
00:09:39,360 --> 00:09:43,000
virtual mashine kwa ajili ya Mac katika
Ili kuendesha Xcode 5.

170
00:09:43,000 --> 00:09:46,460
Lakini ni nifty pretty
programu ya kutumia.

171
00:09:46,460 --> 00:09:51,280
>> Na hivyo, kabla ya sisi tujivinjari ndani ya aina yoyote
ya demo, mimi nataka tu kuonyesha

172
00:09:51,280 --> 00:09:55,700
picha ya nini Xcode inaonekana kama katika yako
dirisha, na kisha pia kuzungumza kuhusu

173
00:09:55,700 --> 00:09:57,670
nini nafasi hii yote ni.

174
00:09:57,670 --> 00:10:01,600
Hivyo, ni aina ya kama kujifunza jinsi ya
kutumia Microsoft Word, ila unataka

175
00:10:01,600 --> 00:10:04,675
kupata familiarized kwa kila
mambo mbalimbali ambayo

176
00:10:04,675 --> 00:10:06,250
ni kwenda hapa.

177
00:10:06,250 --> 00:10:11,160
>> Hivyo kwanza, nataka uhakika wewe
kwa toolbar juu.

178
00:10:11,160 --> 00:10:14,450
Utaona kwamba, saa ya juu,
itabidi jina la faili -

179
00:10:14,450 --> 00:10:18,100
au, kwa kweli, jina lako mradi
na kisha faili jina lako.

180
00:10:18,100 --> 00:10:20,940
Kuchukua kumbuka ya kucheza na
stop vifungo.

181
00:10:20,940 --> 00:10:24,210
Hao ndio kuwa wewe utakuwa
kutumia kuendesha programu yako juu ya

182
00:10:24,210 --> 00:10:25,600
simulator -

183
00:10:25,600 --> 00:10:26,550
iOS simulator.

184
00:10:26,550 --> 00:10:29,940
Hii moja kwa moja kuja na Xcode 5,
hivyo huna kuwa na wasiwasi kuhusu

185
00:10:29,940 --> 00:10:32,070
kushusha aina fulani ya simulator.

186
00:10:32,070 --> 00:10:34,700
Vyombo vya habari tu kucheza na
kisha anaendesha programu yako.

187
00:10:34,700 --> 00:10:39,230
Na unaweza kucheza karibu na wewe, na
utaona jinsi kazi baadaye.

188
00:10:39,230 --> 00:10:42,690
>> Na kisha, katika kituo hicho, bila shaka, ni
ambapo wote wa code yako nzuri ni

189
00:10:42,690 --> 00:10:44,240
kwenda.

190
00:10:44,240 --> 00:10:48,340
Na kisha, kwa upande wa mkono wa kushoto, itabidi
na hii, aina ya, folder -

191
00:10:48,340 --> 00:10:50,340
urambazaji -

192
00:10:50,340 --> 00:10:53,970
na kisha, utapata pia kuona kwamba, pamoja
na folder icon, kuna

193
00:10:53,970 --> 00:10:57,680
kundi la icons nyingine pale kwamba
itakuwa muhimu baadaye.

194
00:10:57,680 --> 00:11:04,710
>> Na kisha, upande wa kulia ni shirika
eneo ambapo unaweza kufanya kazi na

195
00:11:04,710 --> 00:11:09,620
baadhi ya vitu na bayana, wewe
kujua, je, rangi lazima, nini

196
00:11:09,620 --> 00:11:12,040
font Nakala lazima, na kadhalika.

197
00:11:12,040 --> 00:11:15,890
Pamoja na kwamba, kila kitu unaweza kufanya
katika eneo shirika, unaweza

198
00:11:15,890 --> 00:11:17,480
kufanya katika kanuni kama vizuri.

199
00:11:17,480 --> 00:11:21,630
Na hivyo, mimi itabidi kuwa kwenda kwa njia mbili
mifano ya kutumia, tu, hakuna code katika

200
00:11:21,630 --> 00:11:23,730
wote - au kanuni ndogo sana -

201
00:11:23,730 --> 00:11:28,290
mistari code wote, hivyo tu kwamba nyie
kujua nini unaweza na hawezi kufanya katika

202
00:11:28,290 --> 00:11:29,260
Xcode na Lengo-C.

203
00:11:29,260 --> 00:11:32,770
>> Na kisha, mwisho, chini chini,
una eneo utatuzi.

204
00:11:32,770 --> 00:11:37,270
Hivyo, hakuna tena kuwa na kukimbia GDB,
nakadhalika, juu ya programu yako.

205
00:11:37,270 --> 00:11:39,180
Ni moja kwa moja anafanya hivyo kwa ajili yenu.

206
00:11:39,180 --> 00:11:42,880
Na unaweza pia magazeti
mambo ya eneo hili.

207
00:11:42,880 --> 00:11:46,790
Hivyo kweli, baadaye, tutaweza kwenda kupitia
mario.c, kama wewe guys bado kumbuka

208
00:11:46,790 --> 00:11:49,000
kwamba, katika Xcode.

209
00:11:49,000 --> 00:11:50,360
Hivyo kwamba wanapaswa kuwa na furaha.

210
00:11:50,360 --> 00:11:55,870
>> Na kisha, tu kuleta nyuma ya
Lengo-C, nataka kuonyesha nini

211
00:11:55,870 --> 00:11:57,440
unaweza kufanya na kama kauli.

212
00:11:57,440 --> 00:12:03,160
Hivyo, unajua, kwa sababu Lengo-C ni
superset ya C, kila kitu wewe ni,

213
00:12:03,160 --> 00:12:06,890
literally, sawa na C. Wewe tu
kuwa tofauti kidogo.

214
00:12:06,890 --> 00:12:10,810
Hivyo, utasikia taarifa fomu kwa ajili ya kama
taarifa bado ni ile ile - una

215
00:12:10,810 --> 00:12:14,280
kama, na kisha una mabano na
hali ndani ya, na kisha

216
00:12:14,280 --> 00:12:17,150
braces curly kwa lolote
wanataka kufanya ndani ya huko.

217
00:12:17,150 --> 00:12:21,680
>> Hata hivyo, nilitaka kuweka slide hii up
hapa, tu ili kuonyesha kwamba,

218
00:12:21,680 --> 00:12:25,680
kwa sababu sisi ni kushughulika na vitu sasa,
tutakuwa na wanatumia mambo haya

219
00:12:25,680 --> 00:12:31,240
aitwaye kama, ni sawa na kamba, ambayo
ni, kwa bahati, njia ya

220
00:12:31,240 --> 00:12:33,710
kamba au NSString kitu.

221
00:12:33,710 --> 00:12:38,600
Kwa hiyo, neno, katika kesi hii, ni NSString
kitu, na ina njia iitwayo ni

222
00:12:38,600 --> 00:12:44,150
sawa na kamba, na kisha sisi ni kupita
katika ngumu-coded kamba kuona

223
00:12:44,150 --> 00:12:48,110
kama watu hao ni sawa
mmoja kwa mwingine.

224
00:12:48,110 --> 00:12:51,580
>> Maswali yoyote hadi sasa?

225
00:12:51,580 --> 00:12:52,440
OK.

226
00:12:52,440 --> 00:12:56,190
Na, nataka kwenda juu ya
a kwa taarifa pia.

227
00:12:56,190 --> 00:13:01,420
>> Hivyo, kwa mfano, kama sisi alitaka kitanzi
juu ya urefu wa kamba katika C, hii

228
00:13:01,420 --> 00:13:03,710
wanapaswa kuwa ukoo na wewe.

229
00:13:03,710 --> 00:13:07,840
Na, katika Malengo ya-C, mimi nataka
kwa kuonyesha hii, aina ya,

230
00:13:07,840 --> 00:13:09,235
njia aitwaye kuhesabu.

231
00:13:09,235 --> 00:13:13,260

232
00:13:13,260 --> 00:13:15,550
Vizuri, kwa kweli, basi mimi
tu kuchukua nyuma.

233
00:13:15,550 --> 00:13:17,200
Hesabu ni njia ya safu.

234
00:13:17,200 --> 00:13:21,070
Hata hivyo, ni zaidi hasa
mali ya safu, ambayo ni kwa nini

235
00:13:21,070 --> 00:13:22,380
unaweza kutumia dot nukuu.

236
00:13:22,380 --> 00:13:25,870
Lakini mimi si wanataka kupata katika sana ya
mambo haya dhana, mimi nataka tu

237
00:13:25,870 --> 00:13:30,140
kuonyesha jinsi mambo bila kuangalia
kama katika Malengo ya-C dhidi ya C.

238
00:13:30,140 --> 00:13:35,400
>> Na pia, mimi unataka uhakika kwamba
hata mimi tumekuwa kutumia NSUInteger

239
00:13:35,400 --> 00:13:39,860
mbele ya i wangu wote katika Malengo ya-C,
unaweza pia kutumia int, kwa sababu int ni

240
00:13:39,860 --> 00:13:42,290
halali kabisa katika Malengo ya-C, pia.

241
00:13:42,290 --> 00:13:42,475
Ndiyo?

242
00:13:42,475 --> 00:13:44,350
>> Watazamaji: Je, ni tu
Stylistic, au ni -

243
00:13:44,350 --> 00:13:44,760
>> RHED SHI: Yeah.

244
00:13:44,760 --> 00:13:46,060
Hivyo, kama utaona -

245
00:13:46,060 --> 00:13:49,390
hivyo, swali ni kwamba
tu suala la Stylistic.

246
00:13:49,390 --> 00:13:54,820
Kama utaona, nina, aina ya, nyota
kinyota kitu chini chini, na

247
00:13:54,820 --> 00:13:59,870
kiungo kwamba inachukua wewe Stack kufurika
kuunda, ambapo mtu anaelezea

248
00:13:59,870 --> 00:14:03,640
tofauti kati ya int katika
NSInteger na NSUInteger.

249
00:14:03,640 --> 00:14:05,540
Na hivyo, unaweza kusoma kuhusu baadaye.

250
00:14:05,540 --> 00:14:07,640
Slides hizi kuwa, bila shaka,
inapatikana na wewe.

251
00:14:07,640 --> 00:14:10,300

252
00:14:10,300 --> 00:14:11,280
>> Hebu angalia.

253
00:14:11,280 --> 00:14:12,150
OK, kutisha.

254
00:14:12,150 --> 00:14:15,410
Kwa hiyo, hili pia ni pamoja na katika slide
kwa sababu nilifikiri hili lilikuwa kubwa

255
00:14:15,410 --> 00:14:19,370
tovuti ya kwamba utangulizi
kwa Lengo-C syntax.

256
00:14:19,370 --> 00:14:24,410
Hivyo, kwa kweli, kwa nini sio sisi hoja ya
Chrome na kuangalia nje ya tovuti hii?

257
00:14:24,410 --> 00:14:30,650

258
00:14:30,650 --> 00:14:31,300
>> Haki.

259
00:14:31,300 --> 00:14:36,670
Hivyo, nini mimi nataka kuonyesha
guys hapa ni picha hii.

260
00:14:36,670 --> 00:14:41,630
Kwa hiyo, hili ni, aina ya, kwenda kuwa kile
wewe ni kwenda kuona ndani ya yoyote

261
00:14:41,630 --> 00:14:42,890
Xcode file.

262
00:14:42,890 --> 00:14:47,400

263
00:14:47,400 --> 00:14:51,430
Kweli, kwa nini sio sisi tu kuchukua
muda wa, aina ya, kuchukua in

264
00:14:51,430 --> 00:14:53,470
>> Kwa hiyo, kitabu hiki -

265
00:14:53,470 --> 00:14:55,880
kwamba kitu kwamba
sisi ni kushughulika na.

266
00:14:55,880 --> 00:14:59,680
Na kisha, ni wazi kwenda kuwa
kurithiwa kutoka kwa baadhi kitu nyingine, lakini

267
00:14:59,680 --> 00:15:01,810
huna na wasiwasi juu ya hilo.

268
00:15:01,810 --> 00:15:04,430
Na kisha, yake, labda, ina
baadhi ya vigezo wanachama.

269
00:15:04,430 --> 00:15:09,160
>> jambo muhimu nataka kuonyesha
ni mbinu mfano, hapa.

270
00:15:09,160 --> 00:15:12,670
Kwa hiyo, mbinu mfano ni ulionyehsa
na hii ni ishara minus.

271
00:15:12,670 --> 00:15:15,550
Na kisha, kama wewe utakuwa taarifa, sisi ni
tayari kuanza kuona dhana ya

272
00:15:15,550 --> 00:15:17,670
kwa njia tamko, sawa?

273
00:15:17,670 --> 00:15:22,670
kurudi aina, njia jina,, na
basi aina ya hoja, na

274
00:15:22,670 --> 00:15:24,660
kisha jina la hoja.

275
00:15:24,660 --> 00:15:29,090
Na hii ni ishara minus ina maana kwamba ni
mfano mbinu, ambayo ina maana kwamba

276
00:15:29,090 --> 00:15:32,270
mbinu hizi zinapatikana tu kwa
vitu ambayo yamekuwa instantiated.

277
00:15:32,270 --> 00:15:35,050

278
00:15:35,050 --> 00:15:39,100
>> Kulinganisha kwamba, mbinu na pamoja na
ishara mbele yao ni darasa

279
00:15:39,100 --> 00:15:43,640
mbinu, ambayo ina maana kwamba unaweza kupiga
njia hizi, hata kama huna

280
00:15:43,640 --> 00:15:45,970
kitu kuundwa bado.

281
00:15:45,970 --> 00:15:51,600
Hivyo, kwa mfano wazi,
NSString ni darasa.

282
00:15:51,600 --> 00:15:55,850
Na unaweza kupiga, kwa mfano,
mbinu darasa juu ya NSString -

283
00:15:55,850 --> 00:15:58,660
halisi, kama, neno NSString.

284
00:15:58,660 --> 00:16:02,050
>> Hata hivyo, ili kutumia haya
mbinu, kweli

285
00:16:02,050 --> 00:16:03,460
haja ya kuunda kamba.

286
00:16:03,460 --> 00:16:08,980
Kwa mfano, NSString kamba nyota ni sawa na
katika alama ya kutaja, hello dunia.

287
00:16:08,980 --> 00:16:10,910
Na kisha, unaweza kutumia njia hizi -

288
00:16:10,910 --> 00:16:11,990
mfano mbinu -

289
00:16:11,990 --> 00:16:14,790
juu ya kwamba kamba dunia hello.

290
00:16:14,790 --> 00:16:17,825
Kwa hiyo, hiyo ni tofauti kati ya
mbinu mfano na mbinu darasa.

291
00:16:17,825 --> 00:16:20,390

292
00:16:20,390 --> 00:16:21,930
>> Na, sisi tu kufunikwa sehemu hii.

293
00:16:21,930 --> 00:16:25,300

294
00:16:25,300 --> 00:16:33,750
Mali ni jambo lingine ambalo ni
ndani ya vitu, kimsingi.

295
00:16:33,750 --> 00:16:37,530
Na kutangaza yao kwa
katika mali keyword.

296
00:16:37,530 --> 00:16:39,940
Una chaguzi hizi, hapa,
kwamba mimi itabidi kueleza baadaye wakati

297
00:16:39,940 --> 00:16:43,110
sisi kwenda katika demo.

298
00:16:43,110 --> 00:16:43,660
Ndiyo?

299
00:16:43,660 --> 00:16:43,950
Hi.

300
00:16:43,950 --> 00:16:45,440
>> Watazamaji: Unaweza kuvuta, tafadhali?

301
00:16:45,440 --> 00:16:46,130
>> RHED SHI: Ndiyo.

302
00:16:46,130 --> 00:16:46,560
Sorry.

303
00:16:46,560 --> 00:16:49,140
>> Watazamaji: Asante.

304
00:16:49,140 --> 00:16:50,005
>> RHED SHI: Kwamba lazima mengi zaidi.

305
00:16:50,005 --> 00:16:51,240
>> Watazamaji: Yeah.

306
00:16:51,240 --> 00:16:53,940
Asante.

307
00:16:53,940 --> 00:16:56,815
>> RHED SHI: Yeah, tafadhali kuwakumbusha mimi kama
Mimi kusahau kuvuta au kuvuta nje.

308
00:16:56,815 --> 00:17:00,590

309
00:17:00,590 --> 00:17:03,570
Kwa hiyo, hili ni yote nilitaka
kuonyesha kwa -

310
00:17:03,570 --> 00:17:05,970
Ho, kwamba mengi -

311
00:17:05,970 --> 00:17:06,790
kwa tovuti hii.

312
00:17:06,790 --> 00:17:12,210
Hivyo, hebu kwenda nyuma ya slides yetu.

313
00:17:12,210 --> 00:17:17,819
>> Kwa kweli, sasa hebu kuchukua muda
kupiga mbizi katika demo.

314
00:17:17,819 --> 00:17:25,490
Hivyo, tutaweza kuanza na
mpya Xcode mradi huo.

315
00:17:25,490 --> 00:17:33,040
Hivyo, kama wewe utakuwa kufungua Xcode wote wa
mashine yako, ni lazima kuchukua baadhi

316
00:17:33,040 --> 00:17:36,720
ukurasa ambapo anasema, kama, ama wazi
mradi zilizopo au mpya

317
00:17:36,720 --> 00:17:39,230
mradi, na unapaswa
bonyeza mradi mpya.

318
00:17:39,230 --> 00:17:41,477
Na kisha, ni lazima kuchukua
wewe screen hii.

319
00:17:41,477 --> 00:17:41,593
Ndiyo?

320
00:17:41,593 --> 00:17:44,279
>> Watazamaji: Kama hatuna Mac,
wala sisi tu ya aina ya baridi?

321
00:17:44,279 --> 00:17:46,870
>> RHED SHI: Au kuangalia juu ya
na mtu, yeah.

322
00:17:46,870 --> 00:17:47,740
Yeah.

323
00:17:47,740 --> 00:17:50,660
Unaweza baridi, pia.

324
00:17:50,660 --> 00:17:51,570
OK.

325
00:17:51,570 --> 00:17:55,410
>> Hivyo, nini tunakwenda kufanya kwanza, sasa,
ni, kwa kweli, sisi ni kwenda kufanya

326
00:17:55,410 --> 00:17:56,600
moja mtazamo maombi.

327
00:17:56,600 --> 00:18:01,340
Hivyo, kama wewe utakuwa taarifa, nini kubwa
kuhusu Xcode na Apple msaada kwa ajili ya

328
00:18:01,340 --> 00:18:05,690
watengenezaji ni kwamba una mengi ya
templates kufanya kazi na tayari.

329
00:18:05,690 --> 00:18:09,210
Unaweza, kwa mfano, kufanya
bwana-undani maombi.

330
00:18:09,210 --> 00:18:10,920
Unaweza kufanya mchezo -

331
00:18:10,920 --> 00:18:13,860
na kwa kweli, mimi si kwenda katika michezo,
kwa sababu michezo ni hadithi mbalimbali

332
00:18:13,860 --> 00:18:15,320
kwa iOS maendeleo.

333
00:18:15,320 --> 00:18:18,930
Na wao ni aina ya tofauti,
hivyo mimi si kwenda katika hiyo.

334
00:18:18,930 --> 00:18:22,580
>> Basi, kwa kuwa ukurasa makao
maombi.

335
00:18:22,580 --> 00:18:24,010
Una tab maombi -

336
00:18:24,010 --> 00:18:29,350
hivyo kama, kwa mfano, Benki Kuu ya Marekani
pengine ina, kama, programu tabbed.

337
00:18:29,350 --> 00:18:32,140
Ni wale ambapo una
vifungo chini.

338
00:18:32,140 --> 00:18:34,750
Na kisha, una Sprite Kit mchezo.

339
00:18:34,750 --> 00:18:38,670
>> Au unaweza kufanya kazi kutoka mwanzo, ambayo
ni nini tutaweza kufanya baadaye.

340
00:18:38,670 --> 00:18:42,470
Lakini hebu, kwanza, kuanza na
moja mtazamo maombi.

341
00:18:42,470 --> 00:18:48,590
Basi, kutakuwa na kuuliza kwa jina bidhaa,
na tunaweza tu kufanya mtihani.

342
00:18:48,590 --> 00:18:50,190
Shirika jina -

343
00:18:50,190 --> 00:18:54,140
hivyo, jina la shirika,
kampuni kitambulisho -

344
00:18:54,140 --> 00:18:58,100
wale ni muhimu kama wewe ni kwenda
kuweka programu yako juu ya kuhifadhi programu.

345
00:18:58,100 --> 00:19:01,110

346
00:19:01,110 --> 00:19:05,116
Nyingine zaidi ya kwamba, kanuni yako ni kwenda
kukimbia faini kabisa bila hii.

347
00:19:05,116 --> 00:19:09,940
>> Hii ni kwenda kuwa muhimu kama
unataka - hivyo, per se, kama, kuweka programu yako

348
00:19:09,940 --> 00:19:14,080
kwenye simu au kitu yako, na mtihani
nje, unajua, katika maisha halisi -

349
00:19:14,080 --> 00:19:15,360
hii itakuwa muhimu.

350
00:19:15,360 --> 00:19:20,110
Hii inaelekeza kawaida kuhusishwa na
aina fulani ya akaunti developer

351
00:19:20,110 --> 00:19:20,970
na Apple.

352
00:19:20,970 --> 00:19:24,740
>> Na hivyo, najua, pengine, mengi ya wewe
si akaunti zozote developer.

353
00:19:24,740 --> 00:19:26,460
Mimi najua chuo kikuu ina moja.

354
00:19:26,460 --> 00:19:27,630
Nadhani CS ina moja.

355
00:19:27,630 --> 00:19:32,770
Lakini, unaweza email yangu na nitajaribu
kufikiri kuwa nje kwa ajili yenu.

356
00:19:32,770 --> 00:19:38,210
Lakini sasa hivi, nimekuwa tu ya kuweka katika
baadhi ya mambo placeholder hapa.

357
00:19:38,210 --> 00:19:41,250
>> Na unaweza, bila shaka, hapa, kuchagua
kama unataka kuwa ni tu katika

358
00:19:41,250 --> 00:19:44,410
iPhone, katika iPad, au wote wawili -

359
00:19:44,410 --> 00:19:46,630
wote maombi.

360
00:19:46,630 --> 00:19:56,170
Hivyo, kwa sasa, hebu kufanya wote, tu
kuona pande zote mbili za jukwaa.

361
00:19:56,170 --> 00:19:57,120
>> Hebu angalia.

362
00:19:57,120 --> 00:20:01,510
Hiyo, sasa hivi, mimi nina kwenda kuokoa
katika baadhi ya aina ya folder.

363
00:20:01,510 --> 00:20:04,500
Haijalishi ambapo - wewe
Daima unaweza hoja hiyo baadaye.

364
00:20:04,500 --> 00:20:09,380
Na, sasa, sisi ni kuletwa
kwa Xcode mradi wetu.

365
00:20:09,380 --> 00:20:12,890
Mimi bila wasiwasi juu ya haya yote.

366
00:20:12,890 --> 00:20:17,510
Napenda kupendekeza si kugusa yoyote ya
hii, isipokuwa kujua hasa ni nini

367
00:20:17,510 --> 00:20:18,260
unachokifanya.

368
00:20:18,260 --> 00:20:21,750
Kwa hiyo, haya yote, tu kupuuza
kwa sehemu kubwa.

369
00:20:21,750 --> 00:20:26,940
Huwezi haja ya kugusa, na kama wewe
kufanya fujo up baadhi ya mambo hapa, ni

370
00:20:26,940 --> 00:20:28,600
anapata kidogo suala gumu.

371
00:20:28,600 --> 00:20:32,480
>> Hivyo, kwa nini sio sisi kuangalia katika
files juu ya

372
00:20:32,480 --> 00:20:34,700
mkono wa kushoto upande katika nahodha wetu.

373
00:20:34,700 --> 00:20:37,060
Hapa, tuna AppDelegate.h.

374
00:20:37,060 --> 00:20:43,430
Tuna AppDelegate.m Hivyo, kama wewe utakuwa
taarifa, tuna header files, ambayo

375
00:20:43,430 --> 00:20:45,720
mwisho katika dot h, na sisi na
utekelezaji -

376
00:20:45,720 --> 00:20:46,970
kweli, basi mimi zoom in

377
00:20:46,970 --> 00:20:56,270

378
00:20:56,270 --> 00:20:57,060
OK.

379
00:20:57,060 --> 00:20:59,940
Hebu zoom in

380
00:20:59,940 --> 00:21:05,810
>> Haki, hivyo una header files na
una files utekelezaji.

381
00:21:05,810 --> 00:21:07,060
Kweli -

382
00:21:07,060 --> 00:21:08,680

383
00:21:08,680 --> 00:21:09,240
OK.

384
00:21:09,240 --> 00:21:11,800
Hii ni kidogo weird,
lakini kuzaa na mimi.

385
00:21:11,800 --> 00:21:16,140
Basi, kwa sababu tumekuwa wateule maoni moja
maombi, tunakwenda kuwa na

386
00:21:16,140 --> 00:21:17,340
kufanya kazi na storyboard.

387
00:21:17,340 --> 00:21:22,140
>> Hivyo, storyboard ni kitu ambacho Apple
ina kuja na kwa kweli kusaidia

388
00:21:22,140 --> 00:21:26,550
watengenezaji kwa kasi mfano
maombi yao.

389
00:21:26,550 --> 00:21:29,410
Kwa hiyo, hili ni ambapo unaweza kujenga
programu bila kuandika

390
00:21:29,410 --> 00:21:31,710
line moja ya kanuni.

391
00:21:31,710 --> 00:21:35,390
Hata hivyo, katika mtazamo wetu maombi moja,
hatuna, bila shaka, na

392
00:21:35,390 --> 00:21:41,270
faili kwa ajili ya maoni yetu, ambayo
ni mtazamo mtawala.

393
00:21:41,270 --> 00:21:45,150
Hivyo, tuna header na
utekelezaji file, hapa.

394
00:21:45,150 --> 00:21:52,350
>> Na mimi nina kwenda kuvuta nje sasa kwa sababu
tutaweza haja ya kufanya kazi katika storyboard.

395
00:21:52,350 --> 00:21:55,190
Kwa hiyo, hapa ni mtazamo wetu.

396
00:21:55,190 --> 00:22:00,120
Kama sisi, tu, kukimbia programu sasa hivi,
kuna si mengi ya kusisimua kinachoendelea.

397
00:22:00,120 --> 00:22:03,270

398
00:22:03,270 --> 00:22:05,040
Kwa hiyo, utaona screen hii nyeupe.

399
00:22:05,040 --> 00:22:06,110
OK?

400
00:22:06,110 --> 00:22:14,010
>> Na, katika huduma za eneo letu, tunaweza kuongeza
rundo la vitu mbalimbali hiyo.

401
00:22:14,010 --> 00:22:19,290
Hivyo, wakati wewe ni kushughulika na skrini
katika iOS, maoni controllers ni

402
00:22:19,290 --> 00:22:23,150
vitu zinazoelezea,
aina ya, maoni yako.

403
00:22:23,150 --> 00:22:26,980
Kwa hiyo, mtazamo mtawala daima
ina mali aitwaye maoni.

404
00:22:26,980 --> 00:22:29,610
Na mtazamo kwamba, kwa kawaida, ina,
unajua, nini

405
00:22:29,610 --> 00:22:30,810
wanataka kuona juu ya screen.

406
00:22:30,810 --> 00:22:39,210
>> Hivyo, vizuri, hebu tu kuanza kwa kuweka,
labda, labda studio.

407
00:22:39,210 --> 00:22:41,450
Hivyo, hebu kuweka studio ya hapo -

408
00:22:41,450 --> 00:22:44,080
fimbo yake katikati.

409
00:22:44,080 --> 00:22:49,560
Hiyo, sasa nimekuwa clicked juu ya studio, mimi
unaweza kwenda katika mali mkaguzi

410
00:22:49,560 --> 00:22:51,510
na kuanza kubadilisha thamani yake.

411
00:22:51,510 --> 00:22:55,040
Hebu simu yake CS50 Colours.

412
00:22:55,040 --> 00:22:58,220
>> Na, siwezi pia mabadiliko ya font.

413
00:22:58,220 --> 00:23:02,630
Hivyo, badala ya kufanya mfumo, ambayo ni
default, tunaweza kufanya moja desturi.

414
00:23:02,630 --> 00:23:03,770
Tunaweza kubadili -

415
00:23:03,770 --> 00:23:06,453
unajua, Ultralight, kufanya hivyo 32.

416
00:23:06,453 --> 00:23:09,000

417
00:23:09,000 --> 00:23:11,370
Na kisha, tunaweza kufanya sanduku yetu kubwa.

418
00:23:11,370 --> 00:23:14,410
>> Watazamaji: Je, unafikiri wanaweza kuvuta
katika kidogo tu zaidi, labda?

419
00:23:14,410 --> 00:23:14,810
>> RHED SHI: Yeah?

420
00:23:14,810 --> 00:23:16,196
OK.

421
00:23:16,196 --> 00:23:17,450
>> Watazamaji: Tu bomba hilo?

422
00:23:17,450 --> 00:23:19,020
>> RHED SHI: Hebu kuona.

423
00:23:19,020 --> 00:23:20,382
Gani kazi hii?

424
00:23:20,382 --> 00:23:22,270
>> Watazamaji: Just kupita Xcode?

425
00:23:22,270 --> 00:23:23,520
>> RHED SHI: Uhakika.

426
00:23:23,520 --> 00:23:25,620

427
00:23:25,620 --> 00:23:25,940
OK.

428
00:23:25,940 --> 00:23:26,275
Kutisha.

429
00:23:26,275 --> 00:23:27,072
>> Watazamaji: studio chini ya?

430
00:23:27,072 --> 00:23:28,920
studio?

431
00:23:28,920 --> 00:23:29,480
>> RHED SHI: Ni nini hiyo?

432
00:23:29,480 --> 00:23:32,050
>> Watazamaji: Nini drop-down
mara studio chini ya?

433
00:23:32,050 --> 00:23:35,170
>> RHED SHI: Kwa hiyo, swali, ni nini
kuacha chini mara studio chini ya?

434
00:23:35,170 --> 00:23:37,260
Ni lazima, tu, kuwa chini ya hapa.

435
00:23:37,260 --> 00:23:39,330
Mimi nadhani ni mchemraba kitu.

436
00:23:39,330 --> 00:23:40,910
Lakini kwa kawaida, hii ni default -

437
00:23:40,910 --> 00:23:43,250
Mimi naenda tu hapa chini
mpaka mimi kupata studio.

438
00:23:43,250 --> 00:23:45,800

439
00:23:45,800 --> 00:23:47,730
Yeah.

440
00:23:47,730 --> 00:23:48,950
>> Basi sasa, sisi kuwa na studio yetu.

441
00:23:48,950 --> 00:23:51,040
Hebu kituo cha hivyo.

442
00:23:51,040 --> 00:23:56,410
Na Xcode inatupa mwongozo
kwa centering vitu.

443
00:23:56,410 --> 00:23:59,510

444
00:23:59,510 --> 00:24:01,480
Kwa hiyo, sasa hebu kukimbia code yetu tena.

445
00:24:01,480 --> 00:24:08,110

446
00:24:08,110 --> 00:24:08,800
>> Kuna sisi kwenda.

447
00:24:08,800 --> 00:24:10,310
Hivyo, tuna CS50 Colours.

448
00:24:10,310 --> 00:24:13,720

449
00:24:13,720 --> 00:24:15,420
Na sasa basi, tulenge kifungo
huko, sawa?

450
00:24:15,420 --> 00:24:17,480
Kwa sababu tunataka kufanya
hii ya maingiliano.

451
00:24:17,480 --> 00:24:19,410
Hivyo, hebu kuweka kifungo hapa.

452
00:24:19,410 --> 00:24:39,020
Na tutaweza wito huu kifungo "bomba hapa
kuendelea. "Tutaweza kituo cha hayo, pia

453
00:24:39,020 --> 00:24:39,990
Kwa kweli, ni tayari katikati.

454
00:24:39,990 --> 00:24:40,630
Yeah.

455
00:24:40,630 --> 00:24:43,130
>> Kwa hiyo, sasa tuna button.

456
00:24:43,130 --> 00:24:53,000
Na kama sisi kukimbia hii tena, tunakwenda
kuwa na nzuri kidogo kifungo hapa.

457
00:24:53,000 --> 00:24:56,520
Na siwezi bonyeza yake, lakini haina kufanya
kitu chochote, kwa sababu hatujafanya

458
00:24:56,520 --> 00:24:58,500
kitu chochote na kifungo bado.

459
00:24:58,500 --> 00:25:01,740
>> Kwa hiyo, hebu kuunda mtazamo mwingine, sawa?

460
00:25:01,740 --> 00:25:04,160
Kwa hiyo, hebu sema nataka bomba
kuwa kifungo na mimi nataka

461
00:25:04,160 --> 00:25:05,730
kwenda kwenye ukurasa mwingine -

462
00:25:05,730 --> 00:25:06,820
mtazamo mwingine.

463
00:25:06,820 --> 00:25:14,440
Nini mimi kwenda kufanya ni, siwezi kujenga
maoni mtawala, sawa?

464
00:25:14,440 --> 00:25:19,690
Sasa mimi itabidi bonyeza kifungo yangu, na kisha,
Jambo muhimu ni, mimi nina kwenda kwa

465
00:25:19,690 --> 00:25:20,910
bonyeza - au -

466
00:25:20,910 --> 00:25:23,660
ndiyo, udhibiti wa vyombo vya habari juu ya keyboard yangu.

467
00:25:23,660 --> 00:25:24,880
Kudhibiti.

468
00:25:24,880 --> 00:25:27,005
Bonyeza kifungo, na kisha Drag.

469
00:25:27,005 --> 00:25:29,960

470
00:25:29,960 --> 00:25:33,550
>> Hivyo, kumbuka kushikilia kudhibiti muhimu.

471
00:25:33,550 --> 00:25:35,160
Hebu kufanya hivyo tena.

472
00:25:35,160 --> 00:25:40,930
Kwa hiyo, kushikilia kudhibiti, bonyeza, na Drag
kwa nini unataka kufanya.

473
00:25:40,930 --> 00:25:41,520
OK.

474
00:25:41,520 --> 00:25:43,610
>> Na sasa, nina chaguzi kadhaa hapa.

475
00:25:43,610 --> 00:25:47,900
Naweza ama kushinikiza, au naweza kufanya
Modal, au naweza kufanya desturi.

476
00:25:47,900 --> 00:25:50,900
Push ni tu kama una
urambazaji mtawala.

477
00:25:50,900 --> 00:25:54,270
Hivi sasa, mtazamo wetu kwanza sana
mtawala ni si ndani ya yoyote

478
00:25:54,270 --> 00:25:55,610
urambazaji mtawala.

479
00:25:55,610 --> 00:25:59,500
Hivyo, mtawala urambazaji ni moja
kwamba anatoa kifungo nyuma juu ya

480
00:25:59,500 --> 00:26:03,910
programu iOS ambapo una, unajua,
hiyo ya juu kabisa, aina ya, nene bar -

481
00:26:03,910 --> 00:26:06,480
ambapo unaweza kwenda nyuma, au
mbele, na kadhalika.

482
00:26:06,480 --> 00:26:07,740
Hivi sasa, sina hiyo.

483
00:26:07,740 --> 00:26:11,050
Na hivyo, kwamba ni kwa nini siwezi kufanya kushinikiza.

484
00:26:11,050 --> 00:26:12,480
>> Kwa hiyo, mimi clicked juu ya kushinikiza
ajali, hapa.

485
00:26:12,480 --> 00:26:16,480
Na kwa kweli, hebu kukimbia code,
na ni lazima ajali juu yangu.

486
00:26:16,480 --> 00:26:19,770

487
00:26:19,770 --> 00:26:22,960
Tu kama mimi waandishi wa habari kifungo
ingawa, hivyo -

488
00:26:22,960 --> 00:26:23,420
haki.

489
00:26:23,420 --> 00:26:26,480
Kwa hiyo, hili ni mbaya.

490
00:26:26,480 --> 00:26:31,330
>> Na, kama unaweza kuona, hapa, sisi
na ujumbe wa kosa.

491
00:26:31,330 --> 00:26:35,460
Hivyo, "Push segues zinaweza kutumika tu wakati
chanzo mtawala inasimamiwa na

492
00:26:35,460 --> 00:26:40,700
mfano wa UI urambazaji mtawala. "
Kwa hiyo, kwa sababu hii haikuwa ndani ya

493
00:26:40,700 --> 00:26:44,030
urambazaji mtawala,
Sikuweza kufanya hivyo.

494
00:26:44,030 --> 00:26:48,782
>> Hiyo, sasa hivi, mimi nina kurejea
folder, kurejea storyboard.

495
00:26:48,782 --> 00:26:51,680
>> Watazamaji: Nini urambazaji
mtawala, tena?

496
00:26:51,680 --> 00:26:55,260
>> RHED SHI: hiyo, sasa hivi mimi nitakuonyesha.

497
00:26:55,260 --> 00:26:56,200
Hebu angalia.

498
00:26:56,200 --> 00:27:00,510
Kwa hiyo, mimi nina kwenda bonyeza mtazamo huu
mtawala, na kisha mimi nina kwenda

499
00:27:00,510 --> 00:27:03,920
hadi bidhaa -

500
00:27:03,920 --> 00:27:06,240
kweli, hapana, sorry - mhariri.

501
00:27:06,240 --> 00:27:08,360
Na mimi nina kwenda katika -

502
00:27:08,360 --> 00:27:09,350
kweli, je, mimi bonyeza juu yake?

503
00:27:09,350 --> 00:27:10,070
Hapana

504
00:27:10,070 --> 00:27:11,080
Kuna sisi kwenda.

505
00:27:11,080 --> 00:27:16,270
Mimi nina kwenda juu katika mhariri, kwenda chini
embed, na kisha urambazaji

506
00:27:16,270 --> 00:27:17,520
mtawala.

507
00:27:17,520 --> 00:27:20,130

508
00:27:20,130 --> 00:27:20,720
>> OK.

509
00:27:20,720 --> 00:27:27,750
Na, workspace yangu inaonekana kweli messy,
hivyo hebu safi hii up.

510
00:27:27,750 --> 00:27:29,000
Kwa hiyo, haya yote ni storyboard.

511
00:27:29,000 --> 00:27:32,510

512
00:27:32,510 --> 00:27:33,760
Na kwa njia hii -

513
00:27:33,760 --> 00:27:37,030

514
00:27:37,030 --> 00:27:38,280
OK, kuacha -

515
00:27:38,280 --> 00:27:49,320

516
00:27:49,320 --> 00:27:50,860
Mimi unaweza haraka kujenga kitu
kama hii.

517
00:27:50,860 --> 00:27:53,020
Na kisha, sasa siwezi kurudi nyuma, unajua?

518
00:27:53,020 --> 00:27:55,730
>> Lakini hii ni aina ya boring, sawa?

519
00:27:55,730 --> 00:28:03,020
Hivyo, nini nataka kufanya ni, sitaki
kufanya, tu tu, mtazamo

520
00:28:03,020 --> 00:28:03,870
mtawala.

521
00:28:03,870 --> 00:28:07,720
Hebu sema nilitaka kweli kufanya
meza maoni mtawala, hivyo siwezi kuweka katika

522
00:28:07,720 --> 00:28:12,110
baadhi ya rangi nzuri, katika meza.

523
00:28:12,110 --> 00:28:16,210
>> Hiyo, sasa nimekuwa kuweka katika meza maoni yangu
mtawala, mimi haja ya kuunganisha nyuma

524
00:28:16,210 --> 00:28:18,560
kutoka kifungo hii
maoni mtawala.

525
00:28:18,560 --> 00:28:21,780
Hivyo mimi haja ya kufanya kudhibiti wangu,
click, Drag kitu tena.

526
00:28:21,780 --> 00:28:27,318
Na sasa naweza kufanya kushinikiza, kwa sababu mimi kuiweka
ni ndani ya mtawala navigation.

527
00:28:27,318 --> 00:28:32,210
>> Watazamaji: Navigation mtawala tu
utapata kwenda kutoka mahali pa?

528
00:28:32,210 --> 00:28:33,540
>> RHED SHI: Ndiyo.

529
00:28:33,540 --> 00:28:38,670
Hivyo, kitaalam zaidi, ni
kitu ambapo -

530
00:28:38,670 --> 00:28:43,150
hivyo, ndani ya urambazaji
mtawala kitu,

531
00:28:43,150 --> 00:28:44,780
anaendelea kufuatilia kwa safu.

532
00:28:44,780 --> 00:28:48,300
Na kwamba safu ana yote ya baadae
kuona controllers.

533
00:28:48,300 --> 00:28:51,560
Hiyo ndiyo sababu wakati vyombo vya habari nyuma, ni
inakwenda nyuma ukurasa uliopita.

534
00:28:51,560 --> 00:28:55,260
Kwa sababu mtawala urambazaji
kitu, au kificho kwamba inachukua huduma ya

535
00:28:55,260 --> 00:28:58,890
hii kitu, ina safu kwamba anaendelea
kufuatilia ya controllers haya maoni, na

536
00:28:58,890 --> 00:29:01,870
wanaweza basi, unajua, DQ maoni
mtawala na kukupa nyuma

537
00:29:01,870 --> 00:29:02,750
mmoja uliopita.

538
00:29:02,750 --> 00:29:05,200
>> Kwa hiyo, hili ni mambo ya kiufundi, lakini -

539
00:29:05,200 --> 00:29:07,505
na mimi nitakuonyesha baadaye katika
code, kama tuna wakati.

540
00:29:07,505 --> 00:29:10,270
Mimi nina aina ya kukosa kwa wakati, lakini -

541
00:29:10,270 --> 00:29:15,610
>> Hivyo, pamoja na meza maoni,
nini tunaweza kufanya ni -

542
00:29:15,610 --> 00:29:18,440
Ni kawaida moja kwa moja kuweka
kwa Dynamic Mfano -

543
00:29:18,440 --> 00:29:20,640
tunakwenda kufanya hivyo seli Static,
vinginevyo tunakwenda

544
00:29:20,640 --> 00:29:22,920
kukimbia katika baadhi ya matatizo.

545
00:29:22,920 --> 00:29:28,470
>> Na kisha, hebu sema mimi nina kwenda
kuwa na sehemu moja.

546
00:29:28,470 --> 00:29:31,000
Hivyo, sehemu ni kama -

547
00:29:31,000 --> 00:29:35,160
kama wameweza milele kuonekana muziki programu, wakati
una wasanii, sehemu ingekuwa

548
00:29:35,160 --> 00:29:37,830
kuwa A kwa njia ya Z's -

549
00:29:37,830 --> 00:29:38,780
barua -

550
00:29:38,780 --> 00:29:42,600
na kisha, unajua, mtu
safu itakuwa majina msanii.

551
00:29:42,600 --> 00:29:47,460
Na hivyo, nini baridi hapa, ni kwamba naweza
kupata yote ya vitu ndani ya

552
00:29:47,460 --> 00:29:50,430
ya storyboard yangu kwa njia hii
tone-down menu, pia.

553
00:29:50,430 --> 00:29:56,600
>> Kwa hiyo, mimi nina kwenda bonyeza sehemu yangu,
na mimi nataka, unajua, labda tano safu.

554
00:29:56,600 --> 00:30:00,770
Na kisha, ndani ya kila mstari,
Nataka kuweka studio.

555
00:30:00,770 --> 00:30:04,080

556
00:30:04,080 --> 00:30:06,340
Na mimi nina kwenda kuwaita hii Blue.

557
00:30:06,340 --> 00:30:09,530

558
00:30:09,530 --> 00:30:15,630
Na kisha, nataka kuweka UI maoni, wewe
kujua, labda kwa, kama, sanduku kidogo.

559
00:30:15,630 --> 00:30:23,840

560
00:30:23,840 --> 00:30:28,710
>> Ili niweze kuonyesha watu
preview wa rangi.

561
00:30:28,710 --> 00:30:34,150
Na mimi itabidi kurudi nyuma na mali na
mabadiliko hayo rangi ya, oh, mimi si

562
00:30:34,150 --> 00:30:35,510
kujua, hii moja.

563
00:30:35,510 --> 00:30:38,630

564
00:30:38,630 --> 00:30:43,150
>> Na kisha, taarifa pia, hapa, wakati mimi na
vifaa, naweza kuwa na kura

565
00:30:43,150 --> 00:30:46,160
ya vifaa mbalimbali
kwamba kawaida kuona.

566
00:30:46,160 --> 00:30:55,250
kutoa taarifa kiashiria, undani, au
kuangalia alama, au tu kina.

567
00:30:55,250 --> 00:30:59,080
Kwa hiyo, labda tunaweza kufanya, kama, kutoa taarifa
kiashiria, kwa mfano.

568
00:30:59,080 --> 00:31:03,540
>> Na kisha, kwa nini sio sisi kuchukua hizi, nakala
kuweka yao, na kuziweka katika

569
00:31:03,540 --> 00:31:06,740
meza mstari unaofuata.

570
00:31:06,740 --> 00:31:08,115
Hivyo, tunaweza wito za.

571
00:31:08,115 --> 00:31:10,620

572
00:31:10,620 --> 00:31:12,155
Na nipate kuwa na kupanua hii.

573
00:31:12,155 --> 00:31:15,730

574
00:31:15,730 --> 00:31:17,290
Hebu kufanya hivyo njano.

575
00:31:17,290 --> 00:31:20,610
Na kwa njia hii, tunaweza nakala
kuweka njia yetu chini.

576
00:31:20,610 --> 00:31:24,910

577
00:31:24,910 --> 00:31:25,370
Ilikuwa ni nini?

578
00:31:25,370 --> 00:31:26,620
Purple.

579
00:31:26,620 --> 00:31:30,020

580
00:31:30,020 --> 00:31:34,740
>> Kwa hiyo, haya yote ni CS50 ya kawaida
rangi ya kwamba wameweza kuona katika darasa -

581
00:31:34,740 --> 00:31:37,160
kweli, sorry -

582
00:31:37,160 --> 00:31:38,410
au kwenye tovuti.

583
00:31:38,410 --> 00:31:49,700

584
00:31:49,700 --> 00:31:51,260
Hopefully nyie unaweza kuona
nini mimi kufanya hapa.

585
00:31:51,260 --> 00:31:57,270

586
00:31:57,270 --> 00:31:57,890
OK.

587
00:31:57,890 --> 00:31:58,490
Moja ya mwisho.

588
00:31:58,490 --> 00:32:02,040
>> Watazamaji: Je, kuongeza
mstari awali?

589
00:32:02,040 --> 00:32:04,740
>> RHED SHI: Kwa hiyo, swali, jinsi
je, mimi kuongeza safu ya awali?

590
00:32:04,740 --> 00:32:07,500
Nilikwenda sehemu hii meza -
au hata hivyo naweza

591
00:32:07,500 --> 00:32:09,200
kuchagua sehemu meza -

592
00:32:09,200 --> 00:32:11,250
na kisha, hapa, mimi updated
idadi ya mistari.

593
00:32:11,250 --> 00:32:19,920

594
00:32:19,920 --> 00:32:22,505
>> Na, napenda matumaini kwamba hii kazi.

595
00:32:22,505 --> 00:32:30,620

596
00:32:30,620 --> 00:32:31,480
OK.

597
00:32:31,480 --> 00:32:32,870
Hebu tuone kama hii matendo.

598
00:32:32,870 --> 00:32:34,000
Oh, kamili, kutisha.

599
00:32:34,000 --> 00:32:35,300
OK.

600
00:32:35,300 --> 00:32:40,330
Wakati mimi ilikuwa kujenga demo yangu, baadhi ya
mambo yalikuwa si iliyokaa, hivyo, shukrani kwa ajili ya

601
00:32:40,330 --> 00:32:42,510
applause.

602
00:32:42,510 --> 00:32:42,920
>> Yeah.

603
00:32:42,920 --> 00:32:44,770
Kwa hiyo, hebu angalia.

604
00:32:44,770 --> 00:32:47,550
Tutaweza kufanya hii tisa tu kufanya
kila kitu - au kweli, hebu tu

605
00:32:47,550 --> 00:32:51,420
kugeuka yote haya katika kutoa
viashiria.

606
00:32:51,420 --> 00:32:55,790
Na kisha, nini nataka kuonyesha wewe pia
mara jinsi gani naweza kuchukua kila moja ya hizo

607
00:32:55,790 --> 00:32:59,230
safu meza na kuwa nao kuingiliana -

608
00:32:59,230 --> 00:33:00,150
oh.

609
00:33:00,150 --> 00:33:01,400
Hapana

610
00:33:01,400 --> 00:33:05,700

611
00:33:05,700 --> 00:33:06,030
>> Oh.

612
00:33:06,030 --> 00:33:07,230
Pia, nataka kuonyesha wewe -

613
00:33:07,230 --> 00:33:13,080
hapa, siwezi kuweka jina la yangu
urambazaji mtawala, sawa?

614
00:33:13,080 --> 00:33:17,090
Hivyo kweli, utasikia taarifa, kwa haraka kama mimi
iliyoingia mtazamo huu mtawala ndani ya

615
00:33:17,090 --> 00:33:22,010
ya mtawala urambazaji, tunaona
hii bar urambazaji juu ya yetu

616
00:33:22,010 --> 00:33:25,340
uwakilishi storyboard
ya maoni mtawala.

617
00:33:25,340 --> 00:33:29,270
Na hivyo, hii inatupa, kama, Visual,
aina ya, mwongozo wa screen yetu inayoonekana.

618
00:33:29,270 --> 00:33:34,360
Hii ni wazi kwenda
kuwa bar navigation.

619
00:33:34,360 --> 00:33:40,950
>> Na nini nataka kufanya haraka,
sasa, ni kuweka katika mwingine -

620
00:33:40,950 --> 00:33:45,880
hivyo hii meza maoni mtawala mimi na
kuchukua moja ya haya na akawatoa

621
00:33:45,880 --> 00:33:49,800
hapa, na kwamba ni nini kuruhusiwa yangu
haraka, kwa kweli, kujenga meza maoni

622
00:33:49,800 --> 00:33:50,850
mtawala.

623
00:33:50,850 --> 00:33:54,100
Kama sisi na wakati, ingawa, itabidi
kuona kwamba, programmatically, ni

624
00:33:54,100 --> 00:33:57,660
kidogo gumu zaidi kwa kujenga meza
maoni mtawala, kwa sababu kuna

625
00:33:57,660 --> 00:34:02,520
ni michache njia ambazo ni
inahitajika kwa ajili ya wewe, aina ya, kuandika

626
00:34:02,520 --> 00:34:07,130
nje ili kwa meza maoni
mtawala wa kuonyeshwa kwa usahihi.

627
00:34:07,130 --> 00:34:15,340
>> Hata hivyo, mimi nataka tu kuonyesha, sasa,
mfano wa ambapo, kama mimi kuchukua fursa hii,

628
00:34:15,340 --> 00:34:15,920
kwa mfano -

629
00:34:15,920 --> 00:34:18,290
Nimekuwa kuweka katika mtazamo mwingine mtawala.

630
00:34:18,290 --> 00:34:27,320
Na sasa, hebu sema nataka kudhibiti
alt bluu yangu ya kwanza kabisa

631
00:34:27,320 --> 00:34:28,980
meza mstari hapa.

632
00:34:28,980 --> 00:34:31,070
Na mimi nataka kuwaita hii Blue.

633
00:34:31,070 --> 00:34:32,570
Na kisha -

634
00:34:32,570 --> 00:34:34,159
hebu angalia.

635
00:34:34,159 --> 00:34:41,050
Mimi nina mtazamo sasa, na Mimi naweza kubadili
background bluu.

636
00:34:41,050 --> 00:34:45,945
>> Na hivyo, taarifa, hapa, hii drop-down
menu pia anatoa uongozi wa wote

637
00:34:45,945 --> 00:34:47,040
wa vitu hivi.

638
00:34:47,040 --> 00:34:50,530
Kwa hiyo, jambo muhimu kutambua, hapa,
ni kwamba mambo yote haya, hapa -

639
00:34:50,530 --> 00:34:54,330
meza mtazamo huu mtawala, meza
maoni, meza maoni sehemu, meza maoni

640
00:34:54,330 --> 00:34:57,169
kiini - yote haya ni
vitu, katika kanuni.

641
00:34:57,169 --> 00:35:03,752
Hivyo, unajua, studio hivi sasa ni chini ya
maoni maudhui, na kadhalika.

642
00:35:03,752 --> 00:35:05,020
Kadhalika na kadhalika.

643
00:35:05,020 --> 00:35:08,765
>> Hivyo, kama sisi kukimbia kanuni hii, sisi
lazima kuona kitu -

644
00:35:08,765 --> 00:35:15,816

645
00:35:15,816 --> 00:35:17,870
hebu angalia kama hii - yeah.

646
00:35:17,870 --> 00:35:18,670
Hivyo, kuna sisi kwenda.

647
00:35:18,670 --> 00:35:22,120
Lakini, kama sisi kufanya hivyo, hakuna
mambo haya kazi nyingine.

648
00:35:22,120 --> 00:35:22,500
Haki?

649
00:35:22,500 --> 00:35:23,800
Hivyo tu hii moja kazi.

650
00:35:23,800 --> 00:35:29,100
Na, kwa ajili ya muda, mimi si
kwenda katika, unajua, kuweka

651
00:35:29,100 --> 00:35:29,770
chini wale wengine.

652
00:35:29,770 --> 00:35:32,020
Na hii ni mwisho wa,
aina ya, storyboard -

653
00:35:32,020 --> 00:35:33,400
nini nilitaka kuonyesha
kwa storyboard.

654
00:35:33,400 --> 00:35:36,330

655
00:35:36,330 --> 00:35:43,490
>> Na, mimi na kazi nje mfano,
kweli, haki hapa.

656
00:35:43,490 --> 00:35:48,090
Kwa hiyo, hili ni storyboard
kwamba mimi alifanya hapo awali.

657
00:35:48,090 --> 00:35:52,740
Hivyo, kama unaweza kuona, hii ilikuwa
urambazaji yangu mtawala.

658
00:35:52,740 --> 00:35:57,040
Kisha mimi alikuwa na mtazamo wangu wa kwanza mtawala,
wakati huo nilikuwa na meza maoni yangu mtawala,

659
00:35:57,040 --> 00:35:58,980
na wakati huo nilikuwa na yote haya -

660
00:35:58,980 --> 00:36:01,180
hivyo hapo awali, mimi alikuwa akifanya
kitu tofauti sana.

661
00:36:01,180 --> 00:36:04,450
Hivyo, udhuru mambo hayo.

662
00:36:04,450 --> 00:36:07,930
Mimi itabidi pengine safi it up baadaye kabla ya
Mimi kutuma mbali na uzalishaji.

663
00:36:07,930 --> 00:36:12,800
>> Lakini, kama sisi kukimbia hii, tutaweza kuona
kwamba wote wa chaguzi ni

664
00:36:12,800 --> 00:36:14,050
kwa ajili yetu.

665
00:36:14,050 --> 00:36:18,540

666
00:36:18,540 --> 00:36:21,320
Ila sikuweza kufanya asili
wale rangi.

667
00:36:21,320 --> 00:36:26,510
Hivyo, nice maombi rahisi.

668
00:36:26,510 --> 00:36:28,340
>> Sasa, hebu kujaribu kukabiliana
hii programmatically.

669
00:36:28,340 --> 00:36:31,270

670
00:36:31,270 --> 00:36:32,130
OK.

671
00:36:32,130 --> 00:36:37,570
Hivyo, kufanya hivyo, tunakwenda tu
kuanza mwezi Xcode mradi huo.

672
00:36:37,570 --> 00:36:41,920
Tutaweza kufanya hivyo maombi tupu sasa,
kwa sababu hatutaki kuwa na

673
00:36:41,920 --> 00:36:42,380
storyboard.

674
00:36:42,380 --> 00:36:46,590
Kwa hiyo, mimi nina tu kuzuia mwenyewe si
matumizi yoyote ya storyboard, na

675
00:36:46,590 --> 00:36:49,170
maombi tupu si
nipe storyboard.

676
00:36:49,170 --> 00:36:52,256
Hii ni kuzuia
mwenyewe kutoka cheating.

677
00:36:52,256 --> 00:36:54,428
Hebu angalia.

678
00:36:54,428 --> 00:36:55,360
Kusubiri.

679
00:36:55,360 --> 00:36:55,960
Je, I -

680
00:36:55,960 --> 00:36:56,448
ndiyo.

681
00:36:56,448 --> 00:36:57,698
OK.

682
00:36:57,698 --> 00:37:08,650

683
00:37:08,650 --> 00:37:09,180
>> Haki.

684
00:37:09,180 --> 00:37:16,790
Kwa hiyo, hapa, sisi ni wa kushoto na
kitu kingine lakini code.

685
00:37:16,790 --> 00:37:19,460
Hivyo, basi mimi hoja dirisha hili
kidogo juu.

686
00:37:19,460 --> 00:37:22,020

687
00:37:22,020 --> 00:37:22,260
Haki.

688
00:37:22,260 --> 00:37:28,160
Kama unaweza kuona hapa, files tu
sisi ni kupewa ni AppDelegate.h na dot

689
00:37:28,160 --> 00:37:30,500
m, na hatuna
storyboard tena.

690
00:37:30,500 --> 00:37:39,580
>> Hivyo kama sisi kukimbia hii, sisi ni bado kwenda
kupata screen nyeupe, kumshukuru Mungu.

691
00:37:39,580 --> 00:37:42,280
OK - nyeupe screen, lakini kitu kingine.

692
00:37:42,280 --> 00:37:45,260
Na, hapa ni sehemu muhimu.

693
00:37:45,260 --> 00:37:47,810
Hii ni pale ambapo hatua kinachotokea.

694
00:37:47,810 --> 00:37:51,410
Katika matoleo ya awali, kuna
kawaida hakuna code hapa, lakini

695
00:37:51,410 --> 00:37:55,600
storyboard kimsingi hutoa
kanuni kwa ajili ya sehemu hii.

696
00:37:55,600 --> 00:37:57,470
Mimi si kwenda katika maelezo juu ya jinsi.

697
00:37:57,470 --> 00:38:02,890
>> Na nini tunataka kufanya sasa ni, tunataka
kwenda katika hapa, na nafasi hii kidogo

698
00:38:02,890 --> 00:38:05,050
kuanza kujenga programu yetu tena.

699
00:38:05,050 --> 00:38:06,092
Hivyo -

700
00:38:06,092 --> 00:38:06,318
ndiyo?

701
00:38:06,318 --> 00:38:07,450
>> Watazamaji: Zoom?

702
00:38:07,450 --> 00:38:07,770
>> RHED SHI: Zoom.

703
00:38:07,770 --> 00:38:09,020
Yeah, uhakika.

704
00:38:09,020 --> 00:38:13,940

705
00:38:13,940 --> 00:38:14,520
OK.

706
00:38:14,520 --> 00:38:17,380
Mimi nitakuwa kuandika, hivyo hii lazima si
jambo sana.

707
00:38:17,380 --> 00:38:17,940
OK.

708
00:38:17,940 --> 00:38:22,720
>> Hivyo, kwanza, kumbuka sisi alitaka kujenga
mtawala urambazaji, sawa?

709
00:38:22,720 --> 00:38:27,090
Na pia, kama unaweza kuona hapa, Xcode
anafanya kazi kubwa kweli kweli ya

710
00:38:27,090 --> 00:38:28,070
binafsi kujaza.

711
00:38:28,070 --> 00:38:31,650
Hivyo, kama wewe utakuwa taarifa, majina ya
kila kitu ni mengi zaidi ya

712
00:38:31,650 --> 00:38:33,910
kawaida, lakini Xcode inajaza katika kwa ajili yenu.

713
00:38:33,910 --> 00:38:35,710
Hivyo siwezi vyombo vya habari tu kuingia.

714
00:38:35,710 --> 00:38:40,180
>> Hivyo, nataka kujenga UI urambazaji
mtawala pointer, na mimi unaweza kuiita

715
00:38:40,180 --> 00:38:41,430
navigationController.

716
00:38:41,430 --> 00:38:43,040

717
00:38:43,040 --> 00:38:44,470
Sasa, je, mimi nini sasa?

718
00:38:44,470 --> 00:38:49,510
Baada ya ishara hii sawa, nahitaji, kwanza,
kujenga ndani ya kumbukumbu.

719
00:38:49,510 --> 00:38:53,790
Kwa hiyo, mimi nina kwenda kufanya NavigationController
alloc -

720
00:38:53,790 --> 00:38:56,640
hivyo, hii ni sawa na malloc,
kwamba guys kutumika katika C -

721
00:38:56,640 --> 00:38:58,400
na kisha, mimi nina kwenda kwa init yake.

722
00:38:58,400 --> 00:39:03,670
>> Hivyo, ni muhimu kwamba yeyote
kitu kwamba kujenga, unataka

723
00:39:03,670 --> 00:39:04,940
alloc na init yake.

724
00:39:04,940 --> 00:39:08,600
Hiyo inaenda kujenga na
instantialize ni ndani ya kumbukumbu, na

725
00:39:08,600 --> 00:39:10,480
sasa unaweza kutumia.

726
00:39:10,480 --> 00:39:10,780
Wote haki?

727
00:39:10,780 --> 00:39:14,360
Kama huna kufanya hivyo, kitu yako haina
haipo, na wewe utakuwa kukimbia katika kundi

728
00:39:14,360 --> 00:39:17,290
ya matatizo.

729
00:39:17,290 --> 00:39:20,250
>> Na kisha, nataka kujenga
maoni mtawala, sawa?

730
00:39:20,250 --> 00:39:25,580
Hivyo, nataka kujenga UIViewController
nyota -

731
00:39:25,580 --> 00:39:29,620
hivyo, kila kitu ni pointer katika
Lengo-C, na mimi nina kwenda kufanya

732
00:39:29,620 --> 00:39:31,600
kitu sawa, hapa -

733
00:39:31,600 --> 00:39:32,850
alloc, init.

734
00:39:32,850 --> 00:39:38,680

735
00:39:38,680 --> 00:39:40,150
OK.

736
00:39:40,150 --> 00:39:43,450
>> Na kisha nini mimi kwenda kufanya ni, mimi nina
kwenda - kwa hivyo, kumbuka wakati sisi alifanya

737
00:39:43,450 --> 00:39:45,360
embed katika urambazaji mtawala?

738
00:39:45,360 --> 00:39:46,920
Hii ni jinsi ya kufanya hivyo katika kanuni.

739
00:39:46,920 --> 00:39:54,550
Wewe ni kwenda kufanya navigationController

740
00:39:54,550 --> 00:39:55,780
pushViewController -

741
00:39:55,780 --> 00:39:57,636
>> Watazamaji: [inaudible].

742
00:39:57,636 --> 00:39:59,030
Je, hii kutokea kwa sisi, au -?

743
00:39:59,030 --> 00:40:00,080
>> RHED SHI: Oh, yeah.

744
00:40:00,080 --> 00:40:00,550
Hapana

745
00:40:00,550 --> 00:40:02,740
Ni anapenda mimi bora.

746
00:40:02,740 --> 00:40:04,670
No, kutakuwa na kazi kwa ajili yenu, pia.

747
00:40:04,670 --> 00:40:06,700
Kwa hiyo, hizi ni mbinu zote.

748
00:40:06,700 --> 00:40:10,400
Hivyo pushViewController ni njia, na
pia, hasa zaidi, ni

749
00:40:10,400 --> 00:40:13,590
mfano njia ya UI
urambazaji mtawala.

750
00:40:13,590 --> 00:40:20,030
Kwa sababu nilikuwa na kujenga UI yangu urambazaji
mtawala nyota, na kisha mimi

751
00:40:20,030 --> 00:40:24,510
wanaweza kupiga pushViewController hii juu yangu
mfano maalum ya UI urambazaji

752
00:40:24,510 --> 00:40:25,010
mtawala.

753
00:40:25,010 --> 00:40:29,490
>> Watazamaji: Je, tuna kufanya halisi
neno, au gani tayari zipo kwa ajili yake?

754
00:40:29,490 --> 00:40:31,380
>> RHED SHI: Ndiyo, kwa sababu ni mbinu.

755
00:40:31,380 --> 00:40:32,200
Ni kama kazi.

756
00:40:32,200 --> 00:40:33,330
Ni kama printf.

757
00:40:33,330 --> 00:40:34,390
Ni kama scanf.

758
00:40:34,390 --> 00:40:36,250
Ni kama strcompare.

759
00:40:36,250 --> 00:40:40,310
Ila anajua nini kutaka
aina, na taarifa kwamba utakuwa daima

760
00:40:40,310 --> 00:40:42,740
kuja na mambo ambayo ni
kuruhusiwa kisheria kwa ajili yenu.

761
00:40:42,740 --> 00:40:47,620
Kwa hiyo, kama hakuna inaonyesha up hapa,
kisha kuna kitu kibaya.

762
00:40:47,620 --> 00:40:50,550
>> Hivyo, pushViewController.

763
00:40:50,550 --> 00:40:52,580
Kwa hiyo, sasa, nataka kushinikiza
yangu nybildat

764
00:40:52,580 --> 00:40:56,850
UIViewController, na kisha, animated -

765
00:40:56,850 --> 00:40:57,470
labda si.

766
00:40:57,470 --> 00:41:00,110
Kwa sababu hii ni kwenda kuwa
kwanza maoni mtawala.

767
00:41:00,110 --> 00:41:03,210
I mean, hata kama mimi kufanya animated,
pengine si show up, kwa sababu

768
00:41:03,210 --> 00:41:05,050
ni screen ya kwanza.

769
00:41:05,050 --> 00:41:06,540
>> Na kumbuka mabano.

770
00:41:06,540 --> 00:41:08,850
Hivyo, kumbuka jinsi sisi kutumika mabano?

771
00:41:08,850 --> 00:41:11,870
Na ndani ya mabano,
kitu wito kwa njia -

772
00:41:11,870 --> 00:41:15,910
hivyo kitu yetu ni urambazaji
mtawala, na ni njia kushinikiza

773
00:41:15,910 --> 00:41:17,210
maoni mtawala animated.

774
00:41:17,210 --> 00:41:21,920
Na kuona ni jinsi gani inachukua katika hoja mbili,
na wao ni kutengwa na, aina ya,

775
00:41:21,920 --> 00:41:24,390
maneno, na koloni.

776
00:41:24,390 --> 00:41:28,300
Hivyo, Lengo-C anajaribu kufanya ni nzuri
na rahisi kwa wewe kusoma kwa sauti kubwa -

777
00:41:28,300 --> 00:41:33,020
code yako - na kuwa ni nusu,
aina ya, mantiki.

778
00:41:33,020 --> 00:41:37,150
>> Hata hivyo, kufanya tu hii
haitoshi.

779
00:41:37,150 --> 00:41:39,780
Hebu zoom nje sasa.

780
00:41:39,780 --> 00:41:44,210
Kufanya tu hii haitoshi kwa
kupata nini tulipata hapo awali.

781
00:41:44,210 --> 00:41:48,580
Hivyo hapa, utasikia taarifa kwamba kuna
kweli si kwenda kuwa aina yoyote ya

782
00:41:48,580 --> 00:41:50,190
bar, hapa, sawa?

783
00:41:50,190 --> 00:41:54,680
Hakuna bar urambazaji, ambayo njia
kwamba sisi bado si wamezipata yake.

784
00:41:54,680 --> 00:41:58,850
>> Na tunaweza kupima kwamba nje, pia, kwa,
labda, kubadilisha asili ya

785
00:41:58,850 --> 00:42:00,460
ViewController, sawa?

786
00:42:00,460 --> 00:42:01,710
ViewController.background--

787
00:42:01,710 --> 00:42:03,155

788
00:42:03,155 --> 00:42:03,640
ah.

789
00:42:03,640 --> 00:42:07,690
Kwa hiyo, kuona ni jinsi gani ViewController hawakuwa na
background rangi, ingawa mimi

790
00:42:07,690 --> 00:42:08,780
alitaka kupata hiyo?

791
00:42:08,780 --> 00:42:14,080
Na kwamba kwa sababu ViewController
ni chombo kwa maoni.

792
00:42:14,080 --> 00:42:19,490
Hivyo, ina lengo mali hiyo, ambayo
kisha ina rangi ya asili.

793
00:42:19,490 --> 00:42:25,510
>> Na, siwezi kuweka, aina ya tediously,
kwa kupiga rangi

794
00:42:25,510 --> 00:42:28,130
juu ya UIColor kitu.

795
00:42:28,130 --> 00:42:33,210
Hivyo, taarifa hapa, redColor ni mbinu.

796
00:42:33,210 --> 00:42:36,750
Ni njia ya darasa la UIcolor.

797
00:42:36,750 --> 00:42:40,820
Kwa sababu sikuwa na kujenga
mfano halisi ya UIColor ili

798
00:42:40,820 --> 00:42:42,020
kuwaita njia juu yake.

799
00:42:42,020 --> 00:42:45,050
Mimi tu, tu, aliita
juu ya aina-kama jina.

800
00:42:45,050 --> 00:42:49,620
Mimi, kama, aliita juu ya int, kama int alikuwa,
kama, njia hiyo, kwa mfano.

801
00:42:49,620 --> 00:42:52,380
>> Na hivyo, kama sisi kukimbia kanuni hii, tutaweza
taarifa kwamba background ni

802
00:42:52,380 --> 00:42:53,540
kweli si nyekundu.

803
00:42:53,540 --> 00:42:54,790
Bado nyeupe.

804
00:42:54,790 --> 00:42:57,720

805
00:42:57,720 --> 00:43:04,550
Na jinsi gani tunaweza kupata kote kwamba ni,
taarifa jinsi kuna self.window.

806
00:43:04,550 --> 00:43:08,260
Hiyo ni, kama, chombo mwisho
kwa ajili ya maombi yako.

807
00:43:08,260 --> 00:43:11,630
Ni jambo la mwisho kwamba ina
kila kitu juu ya screen, kwa

808
00:43:11,630 --> 00:43:13,650
iPhone au iPad maombi.

809
00:43:13,650 --> 00:43:20,970
>> Na, conveniently, self.window
ina mali hii inayoitwa

810
00:43:20,970 --> 00:43:22,650
rootViewController.

811
00:43:22,650 --> 00:43:26,480
Na kwamba ni kwenda kuwa pointer kwa
kwanza sana maoni mtawala ndani ya

812
00:43:26,480 --> 00:43:27,270
wa programu yako.

813
00:43:27,270 --> 00:43:32,000
Hivyo, nini tunataka kufanya hapa, sasa, ni
kuweka sawa sawa kwa urambazaji wetu

814
00:43:32,000 --> 00:43:32,710
mtawala.

815
00:43:32,710 --> 00:43:33,760
Haki?

816
00:43:33,760 --> 00:43:37,490
Kwa sababu, kitaalam, urambazaji
mtawala ni maoni yetu ya kwanza

817
00:43:37,490 --> 00:43:38,770
mtawala.

818
00:43:38,770 --> 00:43:46,160
Ni anaendelea kufuatilia kwa safu ya maoni mengine
controllers, na sisi kusukuma hii

819
00:43:46,160 --> 00:43:49,810
maoni mtawala katika safu kwamba
katika mtawala navigation.

820
00:43:49,810 --> 00:43:52,640
>> Basi, wewe hawataki kufanya hivyo.

821
00:43:52,640 --> 00:43:54,225
Hiyo si kweli kukusaidia.

822
00:43:54,225 --> 00:43:58,040
Unataka kufanya hii, kama wewe alitaka kufanya
mtawala urambazaji, ambao wengi

823
00:43:58,040 --> 00:44:01,100
ya pengine kwa sababu utasikia wanataka
kwa, aina ya, na aina fulani ya,

824
00:44:01,100 --> 00:44:04,840
kama, menu kwenda nyuma au baadhi ya
homepage ya kurejea, badala ya

825
00:44:04,840 --> 00:44:05,470
screen tupu.

826
00:44:05,470 --> 00:44:05,920
Ndiyo?

827
00:44:05,920 --> 00:44:11,460
>> Watazamaji: Je, ni wasiwasi
kwa wewe kuvuta -

828
00:44:11,460 --> 00:44:12,710
>> RHED SHI: Yeah.

829
00:44:12,710 --> 00:44:15,310

830
00:44:15,310 --> 00:44:15,720
Hivyo, yeah.

831
00:44:15,720 --> 00:44:22,370
Hii ni kanuni, na sasa
hebu mtihani ni nje.

832
00:44:22,370 --> 00:44:27,920
>> Hivyo, kuna sisi kwenda.

833
00:44:27,920 --> 00:44:29,170
Uchawi.

834
00:44:29,170 --> 00:44:30,960

835
00:44:30,960 --> 00:44:32,690
Hivyo, OK.

836
00:44:32,690 --> 00:44:34,420
Asante.

837
00:44:34,420 --> 00:44:35,000
OK.

838
00:44:35,000 --> 00:44:38,690
Basi sasa, nini tunataka kufanya ni - kwa hivyo,
sisi ni aina ya mdogo, hapa, sawa?

839
00:44:38,690 --> 00:44:45,130
Tunaweza uwezekano wa kuandika kila kitu
ndani ya kazi hii moja.

840
00:44:45,130 --> 00:44:48,470
Lakini, si jinsi iOS maendeleo
kwa kawaida kazi.

841
00:44:48,470 --> 00:44:53,030
>> Hivyo, nini tunakwenda kufanya ni, sisi ni
kwenda kujenga baadhi files mpya.

842
00:44:53,030 --> 00:44:57,110
Lakini, zaidi hasa, tunakwenda
kuunda nyingine Lengo-C darasani, au

843
00:44:57,110 --> 00:44:58,010
mwengine -

844
00:44:58,010 --> 00:45:00,700
darasa na vitu ni kubadilishana
hapa.

845
00:45:00,700 --> 00:45:06,460
Na, hapa ni jinsi gani ningeweza, uwezekano,
kujenga kundi jingine la U controllers.

846
00:45:06,460 --> 00:45:12,030
>> Hivyo, ni ndogo darasani, kama wewe utakuwa taarifa,
hapa, ni ndogo darasa la

847
00:45:12,030 --> 00:45:15,910
UI maoni mtawala, lakini siwezi
kuiita jina nyingine yoyote hapa.

848
00:45:15,910 --> 00:45:19,400
Mimi naweza kuita CS50 hii, mimi naweza kuita
mtazamo huu mtawala, mimi naweza kuita

849
00:45:19,400 --> 00:45:21,640
hii blah maoni mtawala -

850
00:45:21,640 --> 00:45:22,400
kitu chochote nataka.

851
00:45:22,400 --> 00:45:24,140
Hii ni jina kwa ajili ya darasa.

852
00:45:24,140 --> 00:45:27,020
Hata hivyo, kinaendelea kuwa muhimu
kwa sababu, kimsingi, nini mimi kufanya

853
00:45:27,020 --> 00:45:29,720
hapa ni, mimi nina kujenga
jina la mtu mwingine darasa.

854
00:45:29,720 --> 00:45:34,140
Hivyo, ni kwenda kuwa, kama, baadhi
aina ya aina au kitu.

855
00:45:34,140 --> 00:45:35,910
Kwa hiyo, ni lazima kidogo ya kurefusha maisha.

856
00:45:35,910 --> 00:45:37,225
Ni si kwenda kuwa maalum sana.

857
00:45:37,225 --> 00:45:40,410

858
00:45:40,410 --> 00:45:44,480
>> Na pia, mimi unataka uhakika
nje njia hizo mbili.

859
00:45:44,480 --> 00:45:48,430
Kwa sababu sisi ni kufanya kila kitu ndani ya
code, wakati mwingine ni rahisi sana

860
00:45:48,430 --> 00:45:53,540
kuleta katika interface file, kama kwamba
Naweza literally Drag na kuacha, kama

861
00:45:53,540 --> 00:45:54,960
sisi ilivyokuwa kwa storyboard -

862
00:45:54,960 --> 00:45:57,810
unajua, studio, au kifungo,
au chochote kingine.

863
00:45:57,810 --> 00:46:01,950
Na hivyo, xibs ni files kwamba kuruhusu
kufanya hivyo, na una kunasa it up

864
00:46:01,950 --> 00:46:04,310
kwa mtazamo huu mtawala file.

865
00:46:04,310 --> 00:46:06,540
>> Kwa hiyo, mimi nina kwenda kwa makusudi
si kuangalia hii.

866
00:46:06,540 --> 00:46:12,510
Kawaida mimi bila kuangalia hii, na kama mimi
tu alifanya hivyo kwa iPhone au iPad, mimi

867
00:46:12,510 --> 00:46:16,340
bila kuangalia hii na tu na moja
kwa, unajua, iPhone au iPad.

868
00:46:16,340 --> 00:46:19,750
Lakini kwa kuwa mimi nina kufanya wote, mimi nina kwenda
kujenga wawili wa baadaye.

869
00:46:19,750 --> 00:46:22,220
Kwa hiyo, mimi nina kwenda kwa makusudi
uncheck hii.

870
00:46:22,220 --> 00:46:23,940
>> Hii ni muhimu pia.

871
00:46:23,940 --> 00:46:27,490
mara nyingi, nimepata mende
ambapo hii si checked.

872
00:46:27,490 --> 00:46:31,930
Na hivyo, ni wazi, faili hii si,
aina ya, kama, ni pamoja na au nje

873
00:46:31,930 --> 00:46:33,740
ndani ya folder mtihani huu.

874
00:46:33,740 --> 00:46:38,180
Na hivyo, kanuni yangu ina kabisa hakuna wazo
ya kuwepo kwa faili hili, na

875
00:46:38,180 --> 00:46:41,080
vinavyosababisha maumivu mengi
na masaa ya debugging.

876
00:46:41,080 --> 00:46:44,360
Lakini, kuhakikisha hii ni checked hivyo
kwamba, unajua, Lengo hii

877
00:46:44,360 --> 00:46:47,510
file ni kwa hii ya maombi.

878
00:46:47,510 --> 00:46:48,310
>> OK.

879
00:46:48,310 --> 00:46:51,680
Kwa hiyo, sasa tumeunda files mbili mpya.

880
00:46:51,680 --> 00:46:54,050
Na files hizi kuangalia pretty tupu.

881
00:46:54,050 --> 00:46:59,550
Na, kwa kweli, hebu pia kuendelea
juu ya kwa kujenga files xib.

882
00:46:59,550 --> 00:47:03,690
Hivyo, awali, nilikuwa katika
Cocoa Touch kuacha chini.

883
00:47:03,690 --> 00:47:06,880
Sasa, mimi nina kwenda katika mtumiaji
Interface kugusa, na kama unaweza kuona, mimi

884
00:47:06,880 --> 00:47:08,120
unaweza kuunda storyboard.

885
00:47:08,120 --> 00:47:11,710
>> Kwa hiyo, hata mimi ilianza na tupu
maombi, mimi bado unaweza kutumia

886
00:47:11,710 --> 00:47:12,340
storyboard.

887
00:47:12,340 --> 00:47:15,480
Pamoja na kwamba, anapata gumu katika suala
jinsi unataka kuwaunganisha

888
00:47:15,480 --> 00:47:16,820
kwamba code yako.

889
00:47:16,820 --> 00:47:18,230
Kwa hiyo, mimi si kwenda huko.

890
00:47:18,230 --> 00:47:22,160
>> Lakini, nini tunataka kufanya
sasa ni kujenga maoni.

891
00:47:22,160 --> 00:47:25,720
Na unaweza kuchagua kwa
iPhone au iPad.

892
00:47:25,720 --> 00:47:30,180
Na kwa kawaida, kuashiria
tofauti - kama wewe ni kufanya

893
00:47:30,180 --> 00:47:31,950
wote maombi -

894
00:47:31,950 --> 00:47:35,980
wewe ama kuweka msisitizo wa iPhone,
au unaweza kufanya Twiddly.

895
00:47:35,980 --> 00:47:36,980
Ni kweli haina jambo.

896
00:47:36,980 --> 00:47:40,890
Ni tu kwa ajili yenu na tofauti
ambayo mtazamo ni kwa ambayo kifaa.

897
00:47:40,890 --> 00:47:43,470

898
00:47:43,470 --> 00:47:44,430
>> Na hivyo, sasa kuangalia.

899
00:47:44,430 --> 00:47:47,550
Mimi na screen kwamba naweza kufanya kazi pamoja.

900
00:47:47,550 --> 00:47:53,530
Na hivyo, kwa mfano, naweza kuweka studio
hapa, unajua, na mimi wanaweza pia kuweka

901
00:47:53,530 --> 00:47:54,820
kifungo mwingine hapa.

902
00:47:54,820 --> 00:47:58,730
Mimi si bother kubadilisha
maadili hapa.

903
00:47:58,730 --> 00:48:09,050
>> Lakini, jambo muhimu hapa ni
kwamba faili mmiliki -

904
00:48:09,050 --> 00:48:13,660
hivyo, mimi nina ndani ya iPhone
maoni, iPhone xib file.

905
00:48:13,660 --> 00:48:18,050
Na chini katika eneo hili urambazaji au
tone-down menu, nataka kwenda

906
00:48:18,050 --> 00:48:19,090
mmiliki faili.

907
00:48:19,090 --> 00:48:22,630
Na hii ni kweli
hatua muhimu hapa.

908
00:48:22,630 --> 00:48:27,780
Nataka kufanya mtazamo darasa
mtawala, ili faili hili xib ni

909
00:48:27,780 --> 00:48:30,030
kwenda kuhusishwa na
maoni yangu mtawala.

910
00:48:30,030 --> 00:48:33,590

911
00:48:33,590 --> 00:48:39,360
Na chochote ambacho mimi kufanya ndani ya maoni yangu
mtawala programmatically ni

912
00:48:39,360 --> 00:48:42,800
kwenda yalijitokeza hapa.

913
00:48:42,800 --> 00:48:46,270
>> Kwa hiyo, hata hivyo, taarifa kwamba -

914
00:48:46,270 --> 00:48:55,995
kweli, wacha kufanya mtazamo huu
background bluu, kwa mfano.

915
00:48:55,995 --> 00:49:00,280

916
00:49:00,280 --> 00:49:01,530
Au kijani.

917
00:49:01,530 --> 00:49:03,870

918
00:49:03,870 --> 00:49:07,950
Na kisha, hivyo kama wewe utakuwa taarifa, nyuma katika
kanuni hii, hii ni wapi tulipata wetu

919
00:49:07,950 --> 00:49:09,200
urambazaji mtawala.

920
00:49:09,200 --> 00:49:12,650

921
00:49:12,650 --> 00:49:18,310
>> Hata kama tulivyofanya hatua hiyo, ni
bado kwenda kuwa nyekundu, si ya kijani.

922
00:49:18,310 --> 00:49:20,350
Na kuna sababu kwa nini.

923
00:49:20,350 --> 00:49:28,090
Ni kwa sababu, wakati sisi inited
mtazamo wetu mtawala, hapa -

924
00:49:28,090 --> 00:49:30,010
sorry, ni mambo kidogo -

925
00:49:30,010 --> 00:49:34,520
wakati sisi inited maoni yetu mtawala hapa,
sisi inited ni ya aina ujumla

926
00:49:34,520 --> 00:49:35,990
UIViewController.

927
00:49:35,990 --> 00:49:36,560
OK?

928
00:49:36,560 --> 00:49:40,560
Hivyo hakuwa hata kufanya
ni pamoja na darasa hili.

929
00:49:40,560 --> 00:49:42,030
>> Basi kumbuka, hii ni kama darasa sasa.

930
00:49:42,030 --> 00:49:47,160
Inaweza kuchukuliwa kama aina, tu
kama UIViewController ni aina.

931
00:49:47,160 --> 00:49:51,080
Na ili kutumia, nini
tunahitaji kufanya ni kuagiza -

932
00:49:51,080 --> 00:49:52,520
kuagiza ViewController -

933
00:49:52,520 --> 00:49:55,750
na, kama unaweza kuona,
autofills yake kwa ajili yangu.

934
00:49:55,750 --> 00:49:56,570
Hivyo, ViewController -

935
00:49:56,570 --> 00:50:02,070
na sasa, hapa, siwezi kubadili hali hii
UIViewController kwa ViewController.

936
00:50:02,070 --> 00:50:05,050
Na sasa, hapa, siwezi kubadili
hii ViewController.

937
00:50:05,050 --> 00:50:07,790

938
00:50:07,790 --> 00:50:09,250
>> Hebu kukimbia hii tena.

939
00:50:09,250 --> 00:50:16,970

940
00:50:16,970 --> 00:50:19,690
Ni bado nyekundu.

941
00:50:19,690 --> 00:50:23,370
Na sababu kwa nini ni
bado nyekundu ni kwa sababu -

942
00:50:23,370 --> 00:50:26,230
Woah, kilichotokea huko?

943
00:50:26,230 --> 00:50:31,500
Sisi alitaka kujiunga xib hii
faili kwa lengo la mtawala.

944
00:50:31,500 --> 00:50:37,540
Hata hivyo, ili kwa kweli kufanya
kwamba, tunahitaji kwenda katika hili.

945
00:50:37,540 --> 00:50:42,980
Na wakati sisi kufanya init, tunataka kufanya
initWithNibName, na kisha tunataka

946
00:50:42,980 --> 00:50:48,910
kufanya katika kamba View_iPhone,
kwa mfano.

947
00:50:48,910 --> 00:50:51,700
Unaweza kupuuza kifungu hapa.

948
00:50:51,700 --> 00:50:54,965
>> Na hii ni kwenda kuruhusu
sisi, kwa kweli -

949
00:50:54,965 --> 00:51:00,620

950
00:51:00,620 --> 00:51:02,160
uh oh, kuna tatizo.

951
00:51:02,160 --> 00:51:09,300

952
00:51:09,300 --> 00:51:09,980
Haki.

953
00:51:09,980 --> 00:51:17,670
>> Na hivyo, kuna tatizo kwa sababu, katika
maoni xib yetu file, tuna studio na

954
00:51:17,670 --> 00:51:18,720
sisi kuwa na kifungo.

955
00:51:18,720 --> 00:51:23,660
Hata hivyo, ingawa tumekuwa na uhusiano
hizo mbili, kuna kitu ndani ya

956
00:51:23,660 --> 00:51:27,440
ViewController.h au ViewController.m
zinazoonyesha wale

957
00:51:27,440 --> 00:51:29,160
kifungo au wale maandiko.

958
00:51:29,160 --> 00:51:32,425
Hivyo, tunahitaji kuandika wale walio katika kama
mali ya maoni mtawala.

959
00:51:32,425 --> 00:51:35,290

960
00:51:35,290 --> 00:51:39,490
>> Kwa hiyo, hii ni jinsi gani kutangaza
mali.

961
00:51:39,490 --> 00:51:43,422
Inachukua katika, kwa kawaida,
njia hizo mbili.

962
00:51:43,422 --> 00:51:48,690
Kwa madhumuni ya sisi na semina hii,
Napenda kusema kwamba, kwa ujumla,

963
00:51:48,690 --> 00:51:52,250
mali zaidi ni nonatomic
na kurejesha.

964
00:51:52,250 --> 00:51:55,420
Unaweza kusoma juu na Google kutafuta,
unajua, tofauti kati ya

965
00:51:55,420 --> 00:51:58,620
nonatomic na kuhifadhi, wewe
kujua, Google au kitu.

966
00:51:58,620 --> 00:52:01,090
Na mimi itabidi kuchukua wewe, kama, Stack
Kufurika, ambapo watu watakuwa na

967
00:52:01,090 --> 00:52:03,605
majibu kwa tofauti
kati ya hizo.

968
00:52:03,605 --> 00:52:07,000
Lakini kwa sasa, kwamba ni nini sisi
wanataka kuwa na wasiwasi na.

969
00:52:07,000 --> 00:52:12,790
>> Na tunataka kufanya UI studio, nyota,
na tunaweza kuiita chochote tunataka.

970
00:52:12,790 --> 00:52:15,710
Tunaweza kuwaita hii, unajua, studio.

971
00:52:15,710 --> 00:52:18,270

972
00:52:18,270 --> 00:52:20,110
Na, tutaweza kujenga mwingine
moja kwa kifungo.

973
00:52:20,110 --> 00:52:24,380

974
00:52:24,380 --> 00:52:29,910
Na kumbuka ni pamoja na kinyota,
kwa sababu sisi ni kushughulika na kuyatumia

975
00:52:29,910 --> 00:52:36,740
pretty much kila mahali ndani ya
Lengo la-C.

976
00:52:36,740 --> 00:52:42,110
>> Hata hivyo, bado si kutatua
tatizo, kama unaweza kuona hapa.

977
00:52:42,110 --> 00:52:50,540
Na sababu ni kwa sababu, wakati sisi
wanataka kuungana xib file studio au

978
00:52:50,540 --> 00:52:55,690
kifungo mpango, au header
na file utekelezaji, tunataka

979
00:52:55,690 --> 00:52:58,255
kuongeza kipande hii ya maadili ya -

980
00:52:58,255 --> 00:53:00,610
outlet.

981
00:53:00,610 --> 00:53:03,600
Taarifa kwamba ni neno muhimu.

982
00:53:03,600 --> 00:53:07,970
>> Na, kwa haraka kama mimi kumaliza kuandika
kuwa nje, ni lazima kuwa haya

983
00:53:07,970 --> 00:53:09,100
duru mbili, hapa.

984
00:53:09,100 --> 00:53:11,200
Kwa kawaida, siyo kujazwa ndani

985
00:53:11,200 --> 00:53:12,920
Mimi nina uhakika kwa nini wao ni.

986
00:53:12,920 --> 00:53:21,370
Lakini kwa kawaida, utakuwa na manually
kuungana nao kwa kwenda upande huu wa

987
00:53:21,370 --> 00:53:23,530
huduma eneo hilo.

988
00:53:23,530 --> 00:53:28,430
>> Na hivyo, hivi sasa, mimi nimepata studio yangu
kuchaguliwa, na mimi nataka Drag hii mpya

989
00:53:28,430 --> 00:53:33,910
inayozungumzia outlet kwa mmiliki file yangu,
na kisha bonyeza Label.

990
00:53:33,910 --> 00:53:40,230
Basi sasa, hatimaye, studio hii ni
kushikamana na studio hii.

991
00:53:40,230 --> 00:53:44,950
Na studio hii ni nini tunakwenda kwa
kutumia programmatically kubadilika

992
00:53:44,950 --> 00:53:49,250
Nakala, font yake, background yake
rangi, na kadhalika.

993
00:53:49,250 --> 00:53:52,430
>> Hivyo, kwa nini sio sisi kufanya
sawa kwa button?

994
00:53:52,430 --> 00:53:54,770
Na kama wewe utakuwa taarifa, kwa kifungo,
ni ngumu zaidi kidogo.

995
00:53:54,770 --> 00:53:59,060
Kwa sababu, I mean, uko walidhani
vyombo vya habari juu ya kifungo, hivyo got mengi

996
00:53:59,060 --> 00:54:02,950
ya chaguzi kwa jinsi ya watumiaji
unaweza vyombo vya habari juu ya kifungo.

997
00:54:02,950 --> 00:54:06,570
Na kisha, tutaweza kuona baadaye kwamba
tunaweza kuunganisha hii wetu

998
00:54:06,570 --> 00:54:09,140
maadili ya kufanya kazi yake.

999
00:54:09,140 --> 00:54:12,770
>> Hivyo, kwa sasa ingawa, tunataka kuungana
ni kifungo halisi

1000
00:54:12,770 --> 00:54:13,570
ndani ya kanuni zetu.

1001
00:54:13,570 --> 00:54:19,640
Kwa hiyo sisi kwenda mpya referencing outlet,
na kisha kufanya kifungo.

1002
00:54:19,640 --> 00:54:22,068
Sasa, hebu kukimbia hii tena.

1003
00:54:22,068 --> 00:54:23,040
Uh oh.

1004
00:54:23,040 --> 00:54:23,890
OK.

1005
00:54:23,890 --> 00:54:25,140
Sijui nini kinaendelea hapa sasa.

1006
00:54:25,140 --> 00:54:48,450

1007
00:54:48,450 --> 00:54:49,700
Ho.

1008
00:54:49,700 --> 00:54:57,380

1009
00:54:57,380 --> 00:54:58,960
Wakati mmoja tu, hapa.

1010
00:54:58,960 --> 00:55:02,490
>> Kweli, kwa nini sio sisi kuchukua
kuangalia mfano mwingine katika

1011
00:55:02,490 --> 00:55:05,800
maslahi ya wakati.

1012
00:55:05,800 --> 00:55:06,200
OK.

1013
00:55:06,200 --> 00:55:10,610
Kwa hiyo, hapa ni tayari kwa urahisi zaidi
mfano kwa ViewController.

1014
00:55:10,610 --> 00:55:13,230

1015
00:55:13,230 --> 00:55:17,110
Kama unaweza kuona hapa, nimekuwa ni pamoja na
mali kwa ajili ya

1016
00:55:17,110 --> 00:55:18,460
studio na kifungo.

1017
00:55:18,460 --> 00:55:20,370
Na kisha, kipande hii ya maadili ya hapa -

1018
00:55:20,370 --> 00:55:21,830
hii IBaction -

1019
00:55:21,830 --> 00:55:27,740
mara uhusiano na kifungo hii hapa.

1020
00:55:27,740 --> 00:55:33,940
Hivyo kama unaweza kuona hapa, Touch Up Inside
ni kushikamana na selector

1021
00:55:33,940 --> 00:55:37,390
aitwaye Button taabu.

1022
00:55:37,390 --> 00:55:41,700
>> Hivyo, tunaweza kweli kwenda kwa njia ya
mwendo tena, hapa, kwa kuchukua Touch Up

1023
00:55:41,700 --> 00:55:48,750
Ndani na akawatoa kwa
Picha ya Mmiliki, na kisha

1024
00:55:48,750 --> 00:55:51,570
bonyeza Button taabu.

1025
00:55:51,570 --> 00:55:52,820
Sasa, hebu kukimbia kanuni zetu.

1026
00:55:52,820 --> 00:55:55,710

1027
00:55:55,710 --> 00:56:02,020
Basi sasa, kifungo hii sasa anafanya kazi na
itachukua sisi kwa ukurasa wa pili.

1028
00:56:02,020 --> 00:56:08,430
>> Na, katika suala la mtazamo wetu mtawala,
hii ni kipande cha kificho kwamba alichukua

1029
00:56:08,430 --> 00:56:10,000
huduma ya Button taabu.

1030
00:56:10,000 --> 00:56:14,260
Na ni muhimu kutambua hapa, kwamba
Nimekuwa kuundwa aina nyingine ya maoni

1031
00:56:14,260 --> 00:56:16,330
mtawala aitwaye meza
maoni mtawala.

1032
00:56:16,330 --> 00:56:19,900
Kwa hiyo, hili ilikuwa sawa na kuunga mkono katika
storyboard, wakati mimi kuvutana moja ya

1033
00:56:19,900 --> 00:56:23,450
haya controllers meza maoni
ndani ya storyboard.

1034
00:56:23,450 --> 00:56:24,470
Mimi nina kujenga mwingine

1035
00:56:24,470 --> 00:56:30,000
>> Pointer kwa meza maoni mtawala,
alloc na init-ing, na kisha kufanya

1036
00:56:30,000 --> 00:56:34,490
binafsi dot urambazaji mtawala,
kushinikiza ViewController, hii mpya

1037
00:56:34,490 --> 00:56:35,350
viewController.

1038
00:56:35,350 --> 00:56:39,750
Na nimekuwa kuweka uhuishaji ndiyo,
kwa sababu sasa ndani ya programu yangu, na mimi

1039
00:56:39,750 --> 00:56:45,670
unataka kweli kuona uhuishaji kwenda
kutoka ukurasa wa nyumbani kwa meza

1040
00:56:45,670 --> 00:56:46,920
maoni mtawala.

1041
00:56:46,920 --> 00:56:48,830

1042
00:56:48,830 --> 00:56:51,110
>> Watazamaji: Je, bado wasiwasi
kuhusu ukusanyaji takataka?

1043
00:56:51,110 --> 00:56:51,840
>> RHED SHI: Ni nini hiyo?

1044
00:56:51,840 --> 00:56:54,740
Hapana

1045
00:56:54,740 --> 00:56:58,970
Hivyo, swali, je, una
kufanya kazi na ukusanyaji takataka?

1046
00:56:58,970 --> 00:57:03,470
Hivyo, Xcode cha 4 kilikuwa na kama ARC, ambayo ni
moja kwa moja kumbukumbu kuhesabu kura.

1047
00:57:03,470 --> 00:57:06,120
Na hivyo, kwa kawaida wakati wa kuanza mpya
mradi, bila kuangalia kwamba, kwa sababu

1048
00:57:06,120 --> 00:57:09,440
hakuna mtu kweli anataka kukabiliana na
kumkomboa kumbukumbu na mambo ya ajabu.

1049
00:57:09,440 --> 00:57:13,720
Lakini nadhani katika Xcode 5, hakuna hata
kwamba chaguo juu ya mradi mpya.

1050
00:57:13,720 --> 00:57:16,750
Hivyo, ni moja kwa moja
gani kwa ajili yenu.

1051
00:57:16,750 --> 00:57:16,920
Ndiyo?

1052
00:57:16,920 --> 00:57:20,970
>> Watazamaji: Je, unaweza kuuza nje
PDF katika storyboard yako?

1053
00:57:20,970 --> 00:57:22,020
>> RHED SHI: Yeah, dhahiri.

1054
00:57:22,020 --> 00:57:28,180
Kwa hiyo, yote haya itakuwa ni pamoja na katika
chanzo code, hivyo guys unaweza kuangalia nje

1055
00:57:28,180 --> 00:57:30,730
halisi Xcode mradi kwa ajili yake.

1056
00:57:30,730 --> 00:57:31,105
Yeah?

1057
00:57:31,105 --> 00:57:35,944
>> Watazamaji: Lakini, I mean, kama, ninaweza
magazeti PDF kwa storyboard yangu?

1058
00:57:35,944 --> 00:57:38,920
Kama mimi nataka tu nje
picha ya kuonyesha mtu.

1059
00:57:38,920 --> 00:57:39,160
>> RHED SHI: Oh yeah.

1060
00:57:39,160 --> 00:57:41,980
Nadhani, labda, unaweza tu
kuchukua screen risasi.

1061
00:57:41,980 --> 00:57:44,350
Yeah, na kuwatuma screen
risasi au kitu.

1062
00:57:44,350 --> 00:57:45,600
Yeah.

1063
00:57:45,600 --> 00:57:49,170

1064
00:57:49,170 --> 00:57:50,570
>> Kwa hiyo, hebu angalia.

1065
00:57:50,570 --> 00:57:56,470
Kwa maslahi ya wakati, nadhani
kwamba wote l inaweza kufunika leo.

1066
00:57:56,470 --> 00:57:59,600
Lakini, najua kwamba, kwa kweli, tu
vigumu kugusa uso wa iOS

1067
00:57:59,600 --> 00:58:00,370
maendeleo.

1068
00:58:00,370 --> 00:58:05,630
Kwa hiyo, tafadhali jisikie huru kuwasiliana nami kama
una maswali yoyote kuhusu iOS

1069
00:58:05,630 --> 00:58:07,000
maendeleo.

1070
00:58:07,000 --> 00:58:12,840
Na, hopefully, mimi utakuwa na uwezo wa safi
juu ya baadhi ya kanuni kwa ajili ya chanzo

1071
00:58:12,840 --> 00:58:16,830
files code, ili itabidi baadhi
mifano nzuri kwa kweli kazi.

1072
00:58:16,830 --> 00:58:21,020
>> Nyingine zaidi ya kwamba, kama wewe guys ni kwenda
kwa CS50 hackathon, mimi au anaweza

1073
00:58:21,020 --> 00:58:25,730
si kuwa huko, na mimi inaweza kusaidia nje
na baadhi ya maendeleo iOS, pia.

1074
00:58:25,730 --> 00:58:26,980
Hivyo, shukrani mengi, guys.

1075
00:58:26,980 --> 00:58:31,168
