CATransition动画添加到UIViewControllers

Question

我想补充CATransition到UIViewControllers里面我是用NSTimer

-(void)playAction:(id)sender 
{ 
[audioPlayer play]; 
[self performSelector:@selector(displayviewsAction:) withObject:nil afterDelay:11.0]; 
} 

- (void)displayviewsAction:(id)sender 
{ 
First *firstController = [[First alloc] init]; 
firstController.view.frame = CGRectMake(0, 0, 320, 480); 
[self.view addSubview:firstController.view]; 
[self.view addSubview:toolbar]; 
[firstController release]; 
self.timer = [NSTimer scheduledTimerWithTimeInterval:23 target:self selector:@selector(Second) userInfo:nil repeats:NO];  
} 

-(void)Second 
{ 
Second *secondController = [[Second alloc] init]; 
secondController.view.frame = CGRectMake(0, 0, 320, 480); 
[self.view addSubview:secondController.view]; 
[self.view addSubview:toolbar]; 
[secondController release]; 
self.timer = [NSTimer scheduledTimerWithTimeInterval:27 target:self selector:@selector(Third) userInfo:nil repeats:NO]; 
} 

我如何添加CATransition这些UIViewControllers当他们从第一到第二等改变显示。

在此先感谢您的所有想法。

使用此 -

-(void)Second { 
    Second *secondController = [[Second alloc] init]; 
    secondController.view.frame = CGRectMake(0, 0, 320, 480); 

    CATransition *transitionAnimation = [CATransition animation]; 
    [transitionAnimation setDuration:1]; 
    [transitionAnimation setType:kCATransitionReveal]; 
    [transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]]; 

    [self.view.layer addAnimation:transitionAnimation forKey:kCATransitionReveal]; 

    [self.view addSubview:secondController.view]; 
    [self.view addSubview:toolbar]; 
    [secondController release]; 
    self.timer = [NSTimer scheduledTimerWithTimeInterval:27 target:self selector:@selector(Third) userInfo:nil repeats:NO]; 
} 

//你可以在此定义自己的CATransition动画类型。
