uiviewanimation

I animated the appearance of my subview with: CATransition *transition = [CATransition animation]; transition.duration = 0.3; transition.type = kCATransitionReveal; [webView.layer addAnimation:transition forKey:nil]; [self.view addSubview:webView]; But now I want to remove my subView. How can I add animation to do this? Like other CATransition? When to add this? Before or after addSubview? Krishnabhadra Well you could do the animation first and on the animationEndListener call removeFromSuperView [UIView animateWithDuration:0.5 delay:1.0 options: UIViewAnimationOptionCurveEaseOut animations:^{

I have some pretty standard flipping action going on: [UIView beginAnimations:@"swapScreens" context:nil]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; [UIView setAnimationDuration:1.0]; [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; To Apple's credit, this style of animation is amazingly easy to work with. Very cool, and I've been able to animate transitions, flips, fades etc. throughout the app very easily. Question : During the flip transition, the background visible 'behind' the two views during

Since upgrading my project to swift 3 my autolayout constraint animations aren't working; to be more specific, they're snapping to the new position rather than animating. UIView.animate(withDuration: 0.1, delay: 0.1, options: UIViewAnimationOptions.curveEaseIn, animations: { () -> Void in constraint.constant = ButtonAnimationValues.YPosition.DefaultOut() self.layoutIfNeeded() }, completion: { (finished) -> Void in // .... }) I know they added the UIViewPropertyAnimator class but am yet to try it. I had this problem too with the newest update to swift 3. To be exact, whenever you want to

I have a view controller that has the following hierarchy: UIViewController | |-view |-presentView (UIView) |-stagedView (UIView) |-UIToolbar I am using the transitionFromView:toView:duration:options:completion: method to animate a page curl up to swap between the presentView and the stagedView . The present and staged view only cover most of the screen and there is a UIToolbar at the bottom. When I use the UIViewAnimationOptionTransitionCurlUp transition, it is animating the whole root view (toolbar included), not just the two views involved. [UIView transitionFromView:self.presentView toView

I have a UIView with a number of subviews and a Tap gesture recognized associated and I want to mimic it having a 'touch' effect. That is, when the tap happens, I want to show the container view to have a different background color and the text of any subview UILabels to also look highlighted. When I receive the tap event from UITapGestureRecognizer, I can change the background color just fine and even set the UILabel to [label setHighlighted:YES]; For various reasons, I cannot change the UIView to UIControl. But if I add some UIViewAnimation to revert the highlighting, nothing happens. Any

I am working on one iPhone application in which I implemented one animation UIViewAnimationTransitionFlipFromLeft. Here my application works fine in the Portrait mode. It is doing the same animation as specified means Flip from Left to Right. But when I am doing this UIViewAnimationTransitionFlipFromLeft in landscape mode then it is not rotating from left to right. Instead of it is rotating from top to bottom. This is really critical issue. Can you help me out to solve this. The code I am using for iPhone application to rotate the view is as follows: CGContextRef context =
