touchesBegan: withEvent: No execution solution

touchesBegan: withEvent: / touchesMoved: withEvent: / touchesEnded: withEvent: etc. can only be captured by UIView (if you have any questions, please point it out, please do not spray the passing big bulls). When we create

UIScrollView orUIImageViewWhen clickedUIScrollViewor UIImageView The touch event will be intercepted, causing the touchesBegan: withEvent:/touchesMoved: withEvent:/touchesEnded: withEvent: and other methods not to be executed. Solution: After UIScrollView or UIImageView intercepts the touch event, let it pass it (that is, pass it to its parent view UIView)

You can do this by writing UIScrollView or UIImageView's category override touchesBegan: withEvent: / touchesMoved: withEvent: / touchesEnded: withEvent: etc.
