I have a UIScrollView which displays UIView with UIImageView a subview. Zooming works great, everything is nice an sharp. I need to do some action on zoomed content (show it in another view). How I can get zoomed content of UIView, meaning content which was processed by UIScrollView zoom routines ? Even when zoomed my UIView content is the same (not zoomed).

Michal - Welcome to StackOverflow.

This answer ( How to capture UIView to UIImage without loss of quality on retina display ) does a good job of showing how to create an image from a view.

If I understand your question correctly, you should be able to create an image from the UIScrollView, and that image would correctly reflect the zoom and clipping done by the UIScrollView.

  • Yes, in general this is correct approach. But for some reason when I check UIScrollView the zoomed content is not updated even if actual view shows it OK. – Michal Misiaszek Mar 21 '19 at 17:08
