Question

I have seen examples of rotating a UIImageView on touch. I have a case where I’m supposed to rotate the UIImageView on scrolling the UIScrollView. The UIImageView is the content of UIScrollView. Any suggestions on this?

Answer 1

set the delegate to scroll view and call this method:

– scrollViewWillBeginDragging:

Inside of that rotate the imageview:

imgView.transform = CGAffineTransformMakeRotation(1.57079633); //90 degrees

then set it back when

– scrollViewDidEndDecelerating:

imgView.transform = CGAffineTransformMakeRotation(-1.57079633); //90 degrees
