问题描述
我使用此代码。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
view = [[UIView alloc] init];
[_window addSubview:view];
[view release];
NSLog(@"count - %d", [view retainCount]);
[self.window makeKeyAndVisible];
return YES;
}
- (IBAction)click{
NSLog(@"count - %d", [view retainCount]);
}
当我点击uibutton时 - 我的视图保留count = 2 。
为什么会发生这种情况？
When i click to uibutton - my view retain count = 2. Why is this happening?
