Question

I’ve made a program which contains pictures that can be dragged to move on the screen.
also I used UIScrollView since the space is larger than the window.
I subclassed UIView as a pictures view to display the picture and handle touches in this class.
picture views are added as subviews to the scrollView.
but now I have a problem:
when I drag the picture, the scrollView moves together with the picture.
I’m wondering if there is a way to consume the touches in the picture class to prevent them from passing to superview.

You should to put your code in “touchesMoved:withEvent:” method of your UIView. If your View will handle this event by yourself, then it should not bubble to superview
