CATransition是如何工作的？

Question

我有兩個觀點，一個是aView，另一個是bView，對aView一個按鈕，我按一下按鈕，我會跳轉到bView，請查看代碼

-(IBAction)jump2b:(id)sender{ 
CATransition *animation = [CATransition animation]; 
animation.delegate = self; 
animation.duration = 0.25f; 
animation.timingFunction = UIViewAnimationCurveEaseInOut; 
animation.fillMode = kCAFillModeForwards; 
animation.removedOnCompletion = NO; 
animation.type = kCATransitionPush; 
animation.subtype = kCATransitionFromTop; 
    [bView.view.layer addAnimation:animation forKey:@"animation"]; 
} 

它不能很好地工作，它可以跳，所以我可以做什麼？感謝

你忘了實際上是在結尾處添加視圖...

-(IBAction)jump2b:(id)sender{ 
    CATransition *animation = [CATransition animation]; 
    animation.delegate = self; 
    animation.duration = 0.25f; 
    animation.timingFunction = UIViewAnimationCurveEaseInOut; 
    animation.fillMode = kCAFillModeForwards; 
    animation.removedOnCompletion = NO; 
    animation.type = kCATransitionPush; 
    animation.subtype = kCATransitionFromTop; 
    [bView.view.layer addAnimation:animation forKey:@"animation"]; 

    //add bView to current view 
    [self.view addSubview:bView]; 
} 

有，爲什麼你不使用的UIView動畫塊原因是什麼？這是因爲對於iOS的4動畫使用的UIView的transitionFromView的推薦方法：toView：持續時間：選擇：完成：應該爲你工作...

[UIView transitionFromView:aView 
        toView:bView 
        duration:0.25 
        options: (UIViewAnimationCurveEaseInOut | UIViewAnimationOptionTransitionCurlUp) 
       completion:nil]; 

我用UIViewAnimationOptionTransitionCurlUp作爲過渡選項的例子，但你可以選擇任何UIViewAnimationOption。
