在AppDelegate CATransition - didFinishLaunchingWithOptions

Question

我已经在另一个应用程序中实现此代码，并且它工作得很好。现在，相同的代码是不是在这里工作（我am导入QuartzCore framewok）...日志消息IS调用。任何人都可以帮助我吗？提前致谢。这是我的代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  

    // Override point for customization after application launch. 
    [NSThread sleepForTimeInterval:1.5]; 

    CATransition *transition = [CATransition animation]; 
    transition.delegate = self; 
    transition.duration = 1.5; 
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; 
    transition.type = kCATransitionFade; 

    [[window layer] addAnimation:transition forKey:nil]; 

    [window addSubview:[navigationController view]]; 
    [window makeKeyAndVisible]; 

    return YES; 
} 

- (void)animationDidStop:(CAAnimation *)theAnimation finished: (BOOL)flag 
{ 
    NSLog(@"Animation did stop!"); 
} 

Answer 1

移动：

[[window layer] addAnimation:transition forKey:nil]; 

下面

：

[window makeKeyAndVisible]; 

你明确地创建动画，但是你申请的动画 “之前” 你想将子视图添加到窗口。通过将它放置在下面，您可以告诉窗口您想要为子视图的位置设置动画。
