View being blocked by UITransitionView after being presented

Question

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.

I've attached an image of the . is another.

I have tried the following:

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];                             }                         }                     }]; 

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.

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.

Example, in your animateTransition(_:):

func animateTransition(transitionContext: UIViewControllerContextTransitioning) {      let containerView = transitionContext.containerView     containerView.isUserInteractionEnabled = false      ... }
