UINavigationController：相反方向弹出视图控制器

Question

我正在尝试调用

[[self navigationController] popViewControllerAnimated:YES]

但使动画从右向左滑动而不是从左向右滑动。有什么简单的方法可以做到这一点吗？我想回到之前的观点。任何帮助表示赞赏。谢谢！

Answer 1

这就是如何在相反方向弹出视图控制器。它对我来说 100% 有效

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];

这是可能的，看看我不久前使用的以下代码，并尝试让它为自己工作。你只需要改变

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可供使用，苹果网站说这种动画是可能的：

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

因此，在您的情况下，您需要使用以下内容：

    [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];

快速版本：

    let animation = CATransition()
    animation.duration = 0.3
    animation.type = .push
    animation.subtype = .fromRight
    animation.timingFunction = CAMediaTimingFunction(name: .easeInEaseOut)
    navigationController?.view.layer.add(animation, forKey: nil)
    navigationController?.popViewController(animated: false)
