IOS - ARC改为非ARC

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

2、修改main.m

1. @autoreleasepool {
2. return UIApplicationMain(argc, argv, nil,    NSStringFromClass([LTAppDelegate class]));
3. }

修改为：

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

3、修改AppDelegate

1. @property (retain, nonatomic) UIWindow *window;

将strong修改为retain。

1. -(void)dealloc
2. {
3. [_window release];
4. [super dealloc];
5. }
