UINavigationController：在相反方向弹出视图控制器

Question

我试图调用[[self navigationController] popViewControllerAnimated:YES]，但使动画从右向左滑动，而不是从左向右滑动。任何简单的方法来做到这一点？我想返回到前一个视图。任何帮助表示赞赏。谢谢！

这是可能的，看看我用了一段时间后面的代码，并尝试使它为自己工作。郁可唯需要改变setAnimationTransition

[UIView beginAnimations:nil context:NULL]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 
[UIView setAnimationDuration:0.75]; 
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO]; 
[UIView commitAnimations]; 

[UIView beginAnimations:nil context:NULL]; 
[UIView setAnimationDelay:0.375]; 
[self.navigationController popViewControllerAnimated:NO]; 
[UIView commitAnimations]; 

有几种不同类型的默认动画使用，苹果网站说，这种动画是可能的：

typedef enum { 
    UIViewAnimationTransitionNone, 
    UIViewAnimationTransitionFlipFromLeft, 
    UIViewAnimationTransitionFlipFromRight, 
    UIViewAnimationTransitionCurlUp, 
    UIViewAnimationTransitionCurlDown, 
} UIViewAnimationTransition; 

所以你的情况，你会想使用以下内容：

[UIView beginAnimations:nil context:nil]; 
    [UIView setAnimationCurve: UIViewAnimationCurveEaseInOut]; 
    [UIView setAnimationDuration:0.75]; 
    [self.navigationController popViewControllerAnimated:NO]; 
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO]; 
    [UIView commitAnimations];

这是如何在相反方向弹出视图控制器。它为我工作100％

CATransition *transition = [CATransition animation]; 
    transition.duration = 0.45; 
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]; 
    transition.type = kCATransitionFromRight; 
    [transition setType:kCATransitionPush]; 
    transition.subtype = kCATransitionFromRight; 
    [self.navigationController.view.layer addAnimation:transition forKey:nil]; 
    [self.navigationController popViewControllerAnimated:NO];
