iOS 7更改pushviewcontroller动画方向

当我按下viewcontroller时，动画总是从右向左。我想将该动画更改为从左到右的反转。 我已经尝试过这个代码，但不起作用。动画仍然是从右向左。我怎样才能简单而正确地做到这一点？我需要帮助。提前谢谢

//NOT WORKING
myViewController *mController = [self.storyboard instantiateViewControllerWithIdentifier:@"myViewController"];

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;

[self.view.layer addAnimation:transition forKey:nil];

[self.navigationController pushViewController:mController animated:YES];

您实际上做得很对，但据我从您的代码中了解，您并没有重写该方法：

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated

因此，您需要从

UINavigationController

继承并重写上述方法

我是这样做的（按+弹出）：

因为这个问题提到了iOS 7，我很惊讶答案竟然没有提到iOS 7中引入的动画转换API

如果你想直接进入GitHub，objc.io的家伙们有一篇很好的帖子，里面有一个链接的项目

查看文档，您将看到以下内容：

@availability(iOS, introduced=7.0)
optional func navigationController(navigationController: UINavigationController, 
animationControllerForOperation operation: UINavigationControllerOperation, 
fromViewController fromVC: UIViewController,
 toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning?

或者在Objective-C中

- (id <UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController
                                   animationControllerForOperation:(UINavigationControllerOperation)operation
                                                fromViewController:(UIViewController *)fromVC
                                                  toViewController:(UIViewController *)toVC  NS_AVAILABLE_IOS(7_0);

我通常在App委托中创建它，这样它就可以在任何地方被引用。您还可以基于每个视图控制器设置委托，创建自定义的UINavigationController子类，或者在您认为合适的任何位置

2.创建自定义动画师 现在我们需要一个符合

UIViewControllerAnimatedTransitioning

协议的对象。每当需要动画过渡时，将调用此对象来应用动画。此示例是一个简单的动画，它在过渡中淡入并展开fromView，使其与推送相关

class CustomPushExpansionTransitioner: NSObject, UIViewControllerAnimatedTransitioning {
    func transitionDuration(transitionContext: UIViewControllerContextTransitioning) -> NSTimeInterval {
        return 1
    }

    func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
        let fromView: UIView = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)!
        let toView: UIView = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)!
        let container = transitionContext.containerView()
        container.addSubview(toView)
        container.bringSubviewToFront(fromView)

        toView.frame = container.convertRect(fromView.bounds, fromView: fromView)

        UIView.animateWithDuration(transitionDuration(transitionContext),
            animations: { () -> Void in
                fromView.alpha = 0
                fromView.transform = CGAffineTransformConcat(fromView.transform, CGAffineTransformMakeScale(1.3, 1.3))
        }) { (complete) -> Void in
            transitionContext.completeTransition(true)
        }
    }
}

3.如有必要，向动画师出售 现在我们需要实现UINavigationController委托，并在需要时提供自定义动画

extension NavigationCoordinationController: UINavigationControllerDelegate {
    func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation, fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        switch operation {
        case .Push:
            return LaunchToHomeTransitioner()
        case .Pop:
            break
        case .None:
            break
        }
        return nil
    }
}

现在，您可以完全控制UINavigationController转换了，您也可以试试这个

CATransition *transition = [CATransition animation];

transition.duration = 0.5;
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromLeft;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];

DrawingResultsViewController *dr = [DrawingResultsViewController createAndShowProfile:YES];

[self.navigationController pushViewController:dr animated:YES];

如果有人在Xamarin.iOS中寻找相同的答案（基于答案），请尝试上述代码：

假设

myViewController

是您的视图控制器，将自定义转换传递到导航控制器层

CATransition *transition = [CATransition animation];

transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;

[self.navigationController.view.layer addAnimation:transition forKey:@"pushViewController"]; 

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

对于Swift 4.0+

1-创建扩展名：

extension UINavigationController {
    func customPopView(_ viewController: UIViewController) {
        let transition: CATransition = CATransition()
        transition.duration = 0.3
        transition.type = CATransitionType.push
        transition.subtype = CATransitionSubtype.fromLeft
        view.layer.add(transition, forKey: nil)
        pushViewController(viewController, animated: false)
    }
}

self.navigationController?.customPopView(yourViewController)

2-呼叫：

extension UINavigationController {
    func customPopView(_ viewController: UIViewController) {
        let transition: CATransition = CATransition()
        transition.duration = 0.3
        transition.type = CATransitionType.push
        transition.subtype = CATransitionSubtype.fromLeft
        view.layer.add(transition, forKey: nil)
        pushViewController(viewController, animated: false)
    }
}

self.navigationController?.customPopView(yourViewController)

尝试这样做：

[self.view.window.layer addAnimation:transition-forKey:nil]而不是：
[self.view.layer addAnimation:transition-forKey:nil]谢谢你。我会试试。您可以在appDelegate中使用
required init
创建一个
UINavigationController
对象。但是AppDelegate本身没有
UINavigationController
对象。您是否只需声明实例，然后根据VC对其进行初始化，并设置单个视图控制器的
UINavigationController
对象？@cococoutch您使用根视图控制器在应用程序委托中创建导航控制器，然后实例化协调控制器。。。或者，您可以将导航控制器划分为子类，并成为其委托人。最后，我声明了变量，并在App委托中将
UIViewController
导航控制器对象按每个视图控制器传递给它。因为故事板。不管怎么说，它是有效的。。谢谢谢谢找到如何在pushViewController中使用动画转换需要一些时间。需要从左滑动，而不是Flip对于RTL语言，例如阿拉伯语，当iOS语言从iPhone/iPad设置更改时，iOS将自动执行此操作。这对我来说很有效，但与正常推送相比，它看起来有点古怪，我得到一些奇怪的黑色背景的过渡，是不存在的正常推动。
CATransition *transition = [CATransition animation];

transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;

[self.navigationController.view.layer addAnimation:transition forKey:@"pushViewController"]; 

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

extension UINavigationController {
    func customPopView(_ viewController: UIViewController) {
        let transition: CATransition = CATransition()
        transition.duration = 0.3
        transition.type = CATransitionType.push
        transition.subtype = CATransitionSubtype.fromLeft
        view.layer.add(transition, forKey: nil)
        pushViewController(viewController, animated: false)
    }
}

self.navigationController?.customPopView(yourViewController)
