解决办法:查看xoxoxoxo的这个方法的文档,替换掉这个方法即可。
2,警告:Declaration of "struct sockaddr" willnot be visible outside of this function
解决办法:在你的开源.m文件中添加 #import
3,警告:Implicit conversion from enumerationtype 'UIInterfaceOrientation' to different enumeration type'UIDeviceOrientation'
解决办法:类型不匹配。跳到出错的那一行,UIInterfaceOrientation强制转换为UIDeviceOrientation就行了。
4,警告:incompatible pointer types assigning to'MyArrayList*'from 'NSMutableArray'
解决办法:加入强制转换(MyArrayList*)
5,警告:'&&'within '||'
问题出处:
6,警告:Warning:The Copy Bundle Resources build phasecontains this target's Info.plist file
解决办法:将Info.plist文件移到Resources目录下,而不要直接放在target下。
7,警告:在使用ASIHttp…第三方库的,运行报错。
解决办法:看你的项目中是否添加CFNetwork.framework、SystemConfiguration.framework,MobileCoreServices.framework,
CoreGraphics.framework和libz.1.2.3.dylib,如果是sdk5.0以上,改添加libz.1.2.5.dylib
解决办法:如果是错误信息的话:
要只是一个警告的话,真机调试可以过。具体解决方法待大神出现。
9,警告:
clang: error:
clang: error: no input files
Command/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clangFailed with exit code 1
解决办法: 在你的主工程文件 target搜素,pch ,找到PrefixHeader
10,警告:
“ARCforbids synthesizing a property of an Objective-C object withunspecified ownership or storageattribute
解决办法:如果定义了ARC有效,那么必须要有所有者属性的定义;所以代码改成下面这样
@property
11,警告:
io6一下的xib系统均没有自动选择UseAutolayout, Supporting iOS 5 and below with xib of iOS6
解决办法:Just un-select “Use Autolayout” in the file inspector of thexib’s view and we are back to the familiar autosizing in sizeinspector and boom,it supports iOS 5 and below.
12,警告:
Warning:
解决办法:找到项目里xxx.png重复,删除重复的资源。
//以下是升级到 xcode 5.0.1之后使用遇到的警告

解决办法:删除模拟器上当前要运行那个APP,重新运行项目。就ok
14,警告:
SpringBoard无法启动应用程序错误:-3
解决办法:退出模拟器,重新运行这个项目。

解决办法:
1、打开终端(实用工具 -->终端),在终端中输入如下命令:
svn ls
然后直接输入 “ p ”

This generally means that another instance of this process wasalready running or is hung in the debugger.Currentlanguage: auto; currentlyobjective-c
解决方法:@H_730_301@可能是电脑内存问题引起,重启电脑即可解决。如果重启解决不了问题,那就是你刚刚改动的代码引起的问题。
3 、错误信息:
@H_730_301@ios5是调试正常的,ios6真机调试的时候,出现如下错误: ld:file is universal (3 slices) but does not contain a(n) armv7sslice: /Users/mac4/Desktop/my desktop/My app/MyApp name 20:09:12/MyApp name/ZBarSDK/libzbar.a for architecturearmv7s
@H_730_301@error:linkercommand Failed with exit code 1 (use -v to seeinvocation)
解决方法:
在Xcode里,点击相应的Target,然后点BuildSettings,找到VALID_ARCHS,看里面的是不是arvm7s,如果不是改成arvm7s就可以了。
4、 错误信息:
error:receiver type 'ViewController' forinstance message does not declare a method with selector'hideSearchBar:'[4]
ViewController中没有声明一个方法选择'hideSearchBar:

解决方法:
就是,@H_730_301@把“@H_730_301@替换成@H_730_301@\"即可。
@H_730_301@NSString*ss=@"{
