Hi everyone, I’m trying to implement drawing on a large image where I can zoom, pan, and draw lines.
Currently, I have a UIScrollView with an UIImageView for the image and a separate UIView on top for drawing. The problem is that the drawing view doesn’t scale correctly when I zoom or pan the image it’s a mess.
Has anyone successfully implemented this? What’s the best approach to have zoomable/pannable images and scalable drawing at the same time?
