从sdk3.2.5升级到sdk 5.1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
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)………
6,警告:Warning:The Copy Bundle Resources build phase contains 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 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
8,警告:xxxooo,missing required architecture i386 in file
解决办法:如果是错误信息的话:Target->Build Settings->Search Paths, 删除FrameworkSearch Paths 里面内容就可以了。
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: 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。
11, 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
12, 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。
13 、 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。
14 、 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。
15、 错误信息:当json从服务端请求时得到的字符串,如果这样写的话,会 错,‘;’ after top level declarator
NSString *ss= @”{“recommend”:”世界末日”,”dogname“:”机器人”}”;
解决方法:
就是,把 “ 替换成 ” 即可。NSString *ss= @”{ ”recommend ”:”世界末日 ”, ”dogname ”: ”机器人 ”}”;
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,多写一个 * 。
Xcode升级到4.4后,出现了一堆的Warning. 上搜了一些办法,总结一下。
32:Jsonkit中的
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
view plaincopy
#define CC_MD5_DIGEST_LENGTH 16
+(NSString *)MD5HashForString:(NSString *)input {
const char *cStr = [input UTF8String];
unsigned char result[CC_MD5_DIGEST_LENGTH];
CC_MD5(cStr, strlen(cStr), result);
return [NSString stringWithFormat: @”%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x”,
result[0], result[1], result[2], result[3],
result[4], result[5], result[6], result[7],
result[8], result[9], result[10], result[11],
result[12], result[13], result[14], result[15]];
}
引入函数定义的头文件
#import
34:ASIDataDecompressor中的警告
format specifies type ‘short’ but the argument has type ‘int’
在+ (NSError *)deflateErrorWithCode:(int)code 和 +(NSError *)inflateErrorWithCode:(int)code中
[NSString stringWithFormat:@”Compression of data failed with code %hi”,code] 中
将code改为 (short)code,类型转换
35:Reachability中警告
Using ‘stringWithString:’ with a literal is redundant
statusString = [NSString stringWithString: @”Not Reachable”];
改为:statusString = @”Not Reachable”;
36.format specifies type ‘id’ but the argument has type ‘const char *’
NSCAssert(NO, @”Unhandled error encountered during SAX parse. msg is %@”, msg);
改为:NSCAssert(NO, @”Unhandled error encountered during SAX parse. msg is %@”, [NSString stringWithUTF8String:msg]);
37 118:65: Using ‘stringWithString:’ with a literal is redundant
改为:self.locationInput.text = @”captured change”;
38 在项目中设置控件的layer属性时,会发生错误,”Property ‘c’ cannot be found in forward class object ‘CALayer *”,
这时需要引入 #import
41,错误
Error launching remote program: failed to get the task for process
解决方法:
把真机上的软件,删除,然后,clean 一下,重新运行就可以了。
42,真机调试的时候,出现
解决方法:
把 ,
43,真机调试的时候,出现 ios Broken pipe
解决方法:
:推出xcode
:断开机器(iphone,ipad,ipod)链接
:重启iPhone在联接xcode,就可以了。
在用xcode4开发的时候,删除不用的文件后, 编译的时候会有missing file的警告,原因是由于SVN或git造成的。
