iphone - 我如何在弹出 View Controller 上做一个翻转动画？

Question

我有一个翻转动画，它是这样的:

Picker *picker = [[Picker alloc] init];

            [self.navigationController pushViewController:picker animated:NO];

            [UIView animateWithDuration:0.5
                             animations:^{ 
                                 [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
                                 } 
                             completion:^(BOOL finished){
                             }];
            [picker release];

这非常有效。但是当我想做 popViewController 回来时，像这样:

[self.navigationController popViewControllerAnimated:NO];

    [UIView animateWithDuration:0.5
                     animations:^{ 

                         [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
                     } 
                     completion:^(BOOL finished){
                     }];

但这行不通，只是返回到 View 而没有动画。

您是否尝试过调用popViewControllerAnimated在动画结束后？
