UINavigationController：弹出视图控制器的方向相反

Question

我正在尝试调用[[self navigationController] popViewControllerAnimated:YES]但是让动画从右向左滑动而不是从左向右滑动。有什么简单的方法吗？我想回到上一个观点。任何帮助表示赞赏。谢谢！

Answer 1

这是一个可以在相反方向弹出视图控制器的方法。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];

Answer 2

有可能，请看一下我之前使用过的以下代码，并尝试让它适合自己。 Yu只需要更改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];

有一些不同类型的默认动画可供使用，苹果网站称这种动画是可能的：

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

因此，在您的情况下，您可能希望使用以下内容：

    [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];
