从sdk3.2.5升级到sdk 7.1中间废弃了很多的方法,还有一些逻辑关系更加严谨了。 1,警告:“xoxoxoxo” is deprecated 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" will not be visible outside of this function 解决办法:在你的开源.m文件中添加 #import <netinet/in.h>
3,警告:Implicit conversion from enumeration type ‘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: if (exists && !isDirectory || !exists)……… 解决办法: if ((exists && !isDirectory) || !exists)………
9,警告: clang: error: no such file or directory: ‘/demo2/控件代码/13/Recorder/Recorder_Prefix.pch‘ clang: error: no input files Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clang failed with exit code 1 解决办法: 在你的主工程文件 target搜素,pch ,找到Prefix Header 把它后面的值,都删除,再运行就解决了。
10,警告: “ARC forbids synthesizing a property of an Objective-C object with unspecified ownership or storage attribute 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 (nonatomic, strong, readonly) NSString *ss;
11,警告: io6一下的xib系统均没有自动选择Use Autolayout, Supporting iOS 5 and below with xib of iOS 6 解决办法: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,警告: Warning: Multiple build commands for output file xxx.png 解决办法:找到项目里xxx.png重复,删除重复的资源。
15,警告: The server certificate failed to verify. 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 https://192.100.1.11?0/svn/xxxxxx(注意下面的url更换成你自己的url地址) 然后直接输入 “ p ” 确认,就可以重新连接了。
16,警告: Bitmasking for introspection of Objective-C object pointers is strongly discouraged. 解决办法: 某数字& 0x1的时候是代表要取最低位是否为1,改成了 if(JK_EXPECT_F(((NSUInteger)object)%2))即可。
18,警告: error: failed to launch ‘/private/var/mobile/Applications/xxxxx‘ -- failed to get the task for process 11140. 解决办法: 重启你的开发手机即可,还有一种可能是你的开发者证书与发布证书搞错了,检查在xcode中证书是否一直 。
1, 错误信息: "_OBJC_CLASS_$ xxxxx ", referenced from: objc-class-ref in ViewController.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) 解决方法: 查看工程,看是不是没有导入相关的框架。或者工程里添加的有相同".m",".h" 文件
2, 错误信息: Couldn‘t register dy.CKRiLiText with the bootstrap server. Error: unknown error code. This generally means that another instance of this process was already running or is hung in the debugger.Current language: auto; currently objective-c 解决方法: 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: ios 5是调试正常的,ios 6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) armv7s slice: /Users/mac4/Desktop/my desktop/My app/MyApp name 20:09:12 /MyApp name/ZBarSDK/libzbar.a for architecture armv7serror:linker command failed with exit code 1 (use -v to see invocation) 解决方法:在Xcode里,点击相应的Target,然后点Build Settings,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‘ for instance 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: 在ViewController .h 中声明一下这个方法 “ hideSearchBar ” 即可。
6 、 错误信息: error: Existing instance variable ‘_datasource‘ for property ‘datasource‘ with assign attribute must be __unsafe_unretained 解决方法: id<ListViewDataSource> _datasource; 改为 __unsafe_unretained id<ListViewDataSource> _datasource:即可
7 、 错误信息: error: No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=i386). 解决方法: targets ->build setting 下的 Build Active Architecture Only 设置 NO 即可.
提示(null) error: could not read CFBundleIdentifier from Info.plist (null)
新建一个同名工程,拷贝其plist文件,将原工程中的plist文件替换掉即可。

31,警告: warning: Semantic Issue: Incompatible integer to pointer conversion assigning to ‘BOOL *‘ (aka ‘signed char *‘) from ‘BOOL‘ (aka ‘signed char‘)
解决办法: 检查 BOOL *换为BOOL就可以了,检查是不是多写一个 * 号。
32:Jsonkit中的警告
Direct access to objective-c‘s isa is deprecated in favor of object_setClass() and object_getClass() object->isa 替换为 object_getClass(object) keyObject->isa 替换为 object_getClass(keyObject) (id)keys[idx]->isa 替换为 object_getClass((id)keys[idx])
format specifies type ‘unsigned long‘ but the argument has type ‘nsuinteger‘ (aka ‘unsigned int‘) 给变量增加(unsigned long)进行类型转换
33:md5加密(iOS SDK中自带了CommonCrypto
Implicit declaration of function ‘CC_MD5‘ is invalid in C99
