Touch in UIScrollview?

Question

I use ScrollviewDelegateProtocol in the viewcontroller, but I use Custom UIView(UIImageview)in this user view.

For some reason touchMovednot called. Anyone have any ideas why this is (not) happening?

Answer 1

If scrolling is enabled in UIScrollView, events touchMoveddo not apply to the contents of the scroll view. As a workaround that depends on what you want to achieve. In my application, I just needed to drag and drop the object inside UIScrollView, and I did the following in touchView handlers for the content:

• touchesBegan: , , , . - UIScrollView
• , , touchesMoved, "" .
• touchesEnded: .

- , UIScrollView (. hitTest:withEvent:)
