Calling -[UIView layoutSubviews] during a custom animation like UIScrollView does

when UIScrollView is scrolling animated (e.g. with setContentOffset:animated:), it periodically calls its layoutSubviews, where subclasses can adjust the layout.

I now want to do something similar with a custom view and a custom animation (+[UIView begin/commitAnimations]). I know I can get the current bounds from the CAlayer's presentation layer, however I do not know how to hook into the animation to be able to periodically call layoutSubviews.

Any help is appreciated.

Thanks, Jochen

In your custom view, can you overide setFrame like this ?

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