ScrollView gesture recognizer eating all touch events

Question

I have a UIScrollView to which I added a single tap gesture recognizer to show/hide some UI overlay using:

UITapGestureRecognizer *singleTap = [         


        

Answer 1

Swift 3.0

 let singleTap = UITapGestureRecognizer(target: self, action: #selector(handleTap(_:)))
 singleTap.cancelsTouchesInView = false
 singleTap.numberOfTapsRequired = 1
 scrollView.addGestureRecognizer(singleTap)

And the selector method be like.

@objc func handleTap(_ recognizer: UITapGestureRecognizer) {
  // Perform operation
}
