Why does touchesBegan stop working when UIImageView in placed inside a UIScrollView?

Question

UIView -> UIImageView

I know I have things somewhat working ok since I can tap on my UIImageView and see an NSLog() statement in my touchesBegan method.

.

UIView -> UIScrollView -> UIImageView

I drag that same UIImageView into a UIScrollView and touchesBegan no longer gets called when I tap on my UIImageView. (I haven't changed anything else. All the same connections, methods, and code remains unchanged.)

Why does touchesBegan no longer work? And what can I do to get it working again?

Answer 1

Add uitapgesture to get event

Code is

  UITapGestureRecognizer *ges11=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(Handeltap:)];
  [imagename addGestureRecognizer:ges11];

Create one action name "Handeltap" U will get called there.

Answer 2

by default UIImageView don't handle user gestures. set UIImageView instance's userInteractionEnabled to YES
