I'm struggling with this issues since two days now and I couldn't find a solution yet. My setup is pretty basic: I've got a UIScrollView, a UIView inside it, return the latter at viewForZoomingInScrollView and there's really nothing more than that. Actually, it works as expected. The issue comes when I add this line at viewDidLoad of my view controller:
viewForZooming.transform = CGAffineTransformMakeRotation(M_PI/2);
Then the scroll view doesn't zoom anymore. Is this related to the frame getting invalidated after transforming the view? Is there any workaround?
Thanks.
