Xcode 升級(jí)后匠题,常常遇到的遇到的警告边涕、錯(cuò)誤缔赠,解決方法從sdk3.2.5升級(jí)到sdk 7.1中間廢棄了很多的方法衍锚,還有一些邏輯關(guān)系更加嚴(yán)謹(jǐn)了。1嗤堰,警告:“xoxoxoxo”? is deprecated解決辦法:查看xoxoxoxo的這個(gè)方法的文檔戴质,替換掉這個(gè)方法即可。2踢匣,警告:Declaration of "struct sockaddr" will not be visible outside of this function解決辦法:在你的開源.m文件中添加 #import3告匠,警告:Implicit conversion from enumeration type 'UIInterfaceOrientation' to different enumeration type 'UIDeviceOrientation'
解決辦法:類型不匹配。跳到出錯(cuò)的那一行离唬,UIInterfaceOrientation強(qiáng)制轉(zhuǎn)換為UIDeviceOrientation就行了后专。
4,警告:incompatible pointer types assigning to 'MyArrayList*'from 'NSMutableArray'
解決辦法:加入強(qiáng)制轉(zhuǎn)換(MyArrayList*)
5男娄,警告:'&&' within '||'
問題出處:
if (exists && !isDirectory || !exists)………
解決辦法: if ((exists && !isDirectory) || !exists)………
6行贪,警告:Warning:The Copy Bundle Resources build phase contains this target's Info.plist file
解決辦法:將Info.plist文件移到Resources目錄下,而不要直接放在target下模闲。
7建瘫,警告:在使用ASIHttp…第三方庫(kù)的,運(yùn)行報(bào)錯(cuò)尸折。
解決辦法:看你的項(xiàng)目中是否添加CFNetwork.framework啰脚、SystemConfiguration.framework, MobileCoreServices.framework,
CoreGraphics.framework和libz.1.2.3.dylib,如果是sdk5.0以上实夹,改添加libz.1.2.5.dylib
8橄浓,警告:xxxooo,missing required architecture i386 in file
解決辦法:如果是錯(cuò)誤信息的話:Target->Build Settings->Search Paths, 刪除FrameworkSearch Paths 里面內(nèi)容就可以了亮航。
要只是一個(gè)警告的話荸实,真機(jī)調(diào)試可以過。具體解決方法待大神出現(xiàn)缴淋。
9准给,警告:
clang: error: no such file or directory: '/demo2/控件代碼/13/Recorder/Recorder_Prefix.pch'
clang: error: no input files
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clang failed with exit code 1
解決辦法: 在你的主工程文件 target搜素,pch 重抖,找到Prefix Header? ? 把它后面的值露氮,都刪除,再運(yùn)行就解決了钟沛。
10畔规,警告:
“ARC forbids synthesizing a property of an Objective-C object with unspecified ownership or storage attribute
解決辦法:如果定義了ARC有效,那么必須要有所有者屬性的定義;所以代碼改成下面這樣
@property (nonatomic, strong, readonly) NSString *ss;
11恨统,警告:
io6一下的xib系統(tǒng)均沒有自動(dòng)選擇Use Autolayout叁扫, Supporting iOS 5 and below with xib of iOS 6
解決辦法:Just un-select “Use Autolayout” in the file inspector of the xib’s view and we are back to the familiar autosizing in size inspector and boom, it supports iOS 5 and below.
12三妈,警告:
Warning: Multiple build commands for output file xxx.png
解決辦法:找到項(xiàng)目里xxx.png重復(fù),刪除重復(fù)的資源陌兑。
//以下是升級(jí)到 xcode 5.0.1 之后使用遇到的警告
13沈跨,警告:
“iOS 模擬器”未能安裝此應(yīng)用程序。
解決辦法:刪除模擬器上當(dāng)前要運(yùn)行那個(gè)APP兔综,重新運(yùn)行項(xiàng)目饿凛。就ok
14,警告:
SpringBoard無(wú)法啟動(dòng)應(yīng)用程序 錯(cuò)誤:-3
解決辦法:退出模擬器软驰,重新運(yùn)行這個(gè)項(xiàng)目涧窒。
15,警告:
The server certificate failed to verify.
解決辦法:
1锭亏、打開終端(實(shí)用工具 -->終端)纠吴,在終端中輸入如下命令:
svn ls https://192.100.1.11?0/svn/xxxxxx(注意下面的url更換成你自己的url地址)
然后直接輸入 “ p ”? 確認(rèn),就可以重新連接了慧瘤。
16戴已,警告:
Bitmasking for introspection of Objective-C object pointers is strongly discouraged.
解決辦法:
某數(shù)字& 0x1的時(shí)候是代表要取最低位是否為1,改成了? if(JK_EXPECT_F(((NSUInteger)object)%2))即可锅减。
17糖儡,警告:
Implicit conversion loses integer precision: 'unsigned long' to 'CC_LONG' (aka 'unsigned int').
解決辦法:
CC_MD5(str,strlen(str), r);,改成了? ? CC_MD5(str, (CC_LONG)strlen(str), r);即可怔匣。
18握联,警告:
error: failed to launch '/private/var/mobile/Applications/xxxxx' -- failed to get the task for process 11140.
解決辦法:
重啟你的開發(fā)手機(jī)即可,還有一種可能是你的開發(fā)者證書與發(fā)布證書搞錯(cuò)了每瞒,檢查在xcode中證書是否一直 金闽。
19,警告:
error: ignoring filxxxxxx/libBaiduMobStat.a, missing required architecture x86_64 in filexxxx/libBaiduMobStat.a
解決辦法:
targets ->build setting 下的? architectures 設(shè)置為 standard architetures(armv7,armv7s)? vaild architectures 設(shè)置為armv7,armv7s剿骨。
20代芜,警告:
error: Directory not found for option '-L/Users/joryoubonxx/BaiduStatistic
解決辦法:
刪除? targets ->build setting 下的? library search path不正確的地址,如果還不行,重新添加第三庫(kù)浓利、clean ,重啟Xcode.即可挤庇。

Error launching remote program: failed to get the task for process
解決方法:
把真機(jī)上的軟件灸眼,刪除,然后墓懂,clean 一下焰宣,重新運(yùn)行就可以了。
42,真機(jī)調(diào)試的時(shí)候捕仔,出現(xiàn)? [attachment=49364]? 這正常匕积,但是不識(shí)別機(jī)器的。
解決方法:
把 榜跌, [attachment=49365] 設(shè)置為以上相對(duì)應(yīng)的版本就可以了闪唆。
43,真機(jī)調(diào)試的時(shí)候,出現(xiàn)? ios Broken pipe
解決方法:
:推出xcode
:斷開機(jī)器(iphone,ipad,ipod)鏈接
:重啟iPhone在聯(lián)接xcode钓葫,就可以了悄蕾。
