黑屏.gif
出现这个黑屏的三个点：
-
FromVC设置了transitioningDelegate (UIViewControllerTransitioningDelegate) FromVC.modalPresentationStyle = UIModalPresentationCustom-
Dismiss的
-(void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext{
...
[containerView addSubview:toVC.view];
...
}
Fix：
-(void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext{
...
if (fromVC.modalPresentationStyle == UIModalPresentationFullScreen) {
[containerView addSubview:toVC.view];
}
...
}
