Call - [UIView layoutSubviews] during custom animations such as UIScrollView

Question

when a UIScrollView scrolls animated (e.g. with setContentOffset:animated: , it periodically calls its layoutSubviews , where subclasses can customize the layout.

Now I want to do something similar with custom view and custom animation ( +[UIView begin/commitAnimations] ). I know that I can get the current borders from the CAlayer view level, however I don’t know how to connect to the animation in order to be able to call layoutSubviews periodically.

Any help is appreciated.

Thanks Jochen

In your custom view, you can override setFrame as follows:

 - (void) setFrame:(CGRect)rect { [super setFrame:rect] [self layoutSubviews]; }
