在呈现后，视图被UITransitionView阻止 [英] View being blocked by UITransitionView after being presented

问题描述

我有一个侧导航控制器并通过UIButton显示它。当我通过 [self presentviewcontroller：NC animated：YES completion：nil] 直接将这个NC作为根视图控制器时，某些原因导致NC的菜单面被 UITransitionView 我无法消失。

I have a side navigation controller and present it via a UIButton. When I make this NC the root view controller directly by [self presentviewcontroller: NC animated: YES completion: nil], some reason the menu side of the NC is blocked by a UITransitionView that I cannot get to disappear.

我附上了是另一个。

我尝试了以下内容：

UIWindow *window = [(AppDelegate *)[[UIApplication sharedApplication] delegate] window];
    window.backgroundColor = kmain;


    CATransition* transition = [CATransition animation];
    transition.duration = .5;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype = kCATransitionFromTop;

    [nc.view.layer addAnimation:transition forKey:kCATransition];

    [UIView transitionWithView:window
                      duration:0.5
                       options:UIViewAnimationOptionTransitionNone
                    animations:^{ window.rootViewController = nc; }
                    completion:^(BOOL finished) {
                        for (UIView *subview in window.subviews) {
                            if ([subview isKindOfClass:NSClassFromString(@"UITransitionView")]) {
                                [subview removeFromSuperview];
                            }
                        }
                    }];

但它非常hacky，并且随着窗口的rootviewcontroller在转换过程中发生变化，它有点儿波涛汹涌的部分导航控制器和右上角变黑。它看起来非常糟糕。

But it is very hacky, and as the rootviewcontroller of the window changes during the transition, it's a little choppy and part of the navigationcontroller and the top right corner turn black. It looks very bad.

推荐答案

通过 UITransitionView 获取点击事件，将 containerView 的 userInteractionEnabled 设置为 false 。如果您使用 UIViewControllerAnimatedTransitioning 进行自定义过渡动画。

To get tap events through the UITransitionView, set the containerView's userInteractionEnabled to false. This is if you're doing a custom transition animation by using UIViewControllerAnimatedTransitioning.

示例，在<$ c中$ c> animateTransition（_：）：

func animateTransition(transitionContext: UIViewControllerContextTransitioning) {

    let containerView = transitionContext.containerView()        
    containerView.userInteractionEnabled = false

    ...
}
