iOS/oc取消arc[转]

1、project -> Build settings -> Apple LLVM complier 3.0 - Language -> objective-C Automatic Reference Counting设置为NO;

 

2、修改main.m

@autoreleasepool {  
        return UIApplicationMain(argc, argv, nil,    NSStringFromClass([LTAppDelegate class]));  
 }  

　　

 

修改为：

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];  
    int retVal = UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));  
    [pool release];  
    return retVal;  

　　

 

3、修改AppDelegate

 

@property (retain, nonatomic) UIWindow *window;  

　　

 将strong修改为retain。

-(void)dealloc  
{  
    [_window release];  
    [super dealloc];  
}
