UITapGestureRecognizer on UIScrollView

Question

I setup a UITapGestureRecognizer on a UIScrollView in the storyboard. The Scroll View contains other contents (two UIView, one UIWebView).

The Gesture Recognizer properties are as follows:

• Action: dismissPopover
• delegate: postViewController
• gestureRecognizers: Scroll View
• state: enabled
• numberOfTapsRequired: 1
• numberOfTouchesRequired: 1
• cancelTouchesInView: YES
• delayTouchesBegan: NO
• delayTouchesEnded: YES

The Scroll View (relevant) properties are as follows:

• userInteractionEnabled: YES
• canCancelContentTouches: YES

However, when I tap anywhere on the Scroll View, the gesture does not work.

Answer 1

The delegate class (conforming to UIGestureRecognizerDelegate) must implement

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

This way, the tap gesture will work.
