Question

I’m trying to animate a UIView so that it can grow larger when tapping a button and shrinks down to its original size by tapping the button again.

I do this by adjusting frame to its new size and origin and running the code below.

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
self.theView.frame = frame;
[UIView commitAnimations];

When animating to a bigger size the animation is how it should be. But when animating to its original size (smaller) the view is re-sized instantly and then animated to its designated location.

What I need is that the resizing to the smaller frame is animated as well.

I’ve tried adjusting the autoresizingMask as well, but that didn’t change anything.

Hope someone can help.

thanks.

Answer 1

I worked around this problem when releasing my app by just removing the animation.
It kept bugging me in the back of my mind, so just this week I thought that maybe by using the center property and the size instead of the origin it would make a difference.

So I decided to test this out. Guess what. The problem doesn’t occur when using sdk 4.x

Thanks all for trying to help me out.
