animateKeyframesWithDuration make screen Not responding after animation

ios, uiview, uiviewanimation

Solution

I added this line in the completion block:

[transitionContext completeTransition:NO];

That fix my problem.

Problem

I use `animateKeyframesWithDuration` to simple animate my view: ``` [UIView animateKeyframesWithDuration:1.0 delay:0.0 options:0 animations:^{ [UIView addKeyframeWithRelativeStartTime:0.0 relativeDuration:0.5 animations:^{ containerView.center = CGPointMake(containerView.center.x, 150); }]; [UIView addKeyframeWithRelativeStartTime:0.5 relativeDuration:0.5 animations:^{ containerView.center = oldCenter; }]; }completion:^(BOOL finished) { }]; ``` After the animation finished (completion block called with `finished = YES`), the `UIViewController` isn't responsive, e.g. I can't press any `UIButton` on top the `UIViewController`. Why that?
