问题 I have problems with transitionWithView and animateWithDuration . One of my animateWithDuration blocks doesn't transition, it is a sudden change, and transitionWithView does not temporarily disable user interaction.

How to use the default iOS7 UIAnimation curve

由 ぐ巨炮叔叔 提交于 2019-11-28 06:25:53
iOS7 animations don't behave the same way as in iOS6. They appear to use a different bezier curve. Where iOS6 uses a kind of "easeInOutSine" curve, iOS7 is more of the "easeInOutExpo" kind. ( http://matthewlein.com/ceaser/ ) Is there a way to use that curve? I want to sync my animations when the keyboard opens/closes. Here's how I do it (at least when the keyboard is about to be shown) - (void)keyboardWillShow:(NSNotification *)notification { NSDictionary *keyboardAnimationDetail = [notification userInfo]; UIViewAnimationCurve animationCurve = [keyboardAnimationDetail

I have a UIScrollView here where I'm adding displaying a label in the middle of the screen when the user has scrolled to a page, the problem is that while the animation is going the user can't scroll to the next page (all user interaction seem to be disabled) until the animation is over. Here's my code for displaying the label. if(!scrollView.dragging) [UIView animateWithDuration:0.3 delay:0.3 options:UIViewAnimationOptionCurveEaseOut animations:^(void){ [vesselNameLabel setFrame:frame]; } completion:^(BOOL finished){}]; So how would I get out of this canceling user interaction on the
