UIScrollView breaks gesture recognizers in subviews

Question

What is the correct way to allow scrollview to pass gestures to the subviews?

Answer 1

You should add gesture recognizer to ScrollView like this:

        let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: "handleTap:")
        scrollView.addGestureRecognizer(tapGestureRecognizer)

Then handle the tap like this:

func handleTap(tap: UITapGestureRecognizer)  {

        let location = tap.locationInView(tap.view)

        for i in 0..<scrollView.subviews.count{
            let subViewTapped = scrollView.subviews[i]
            if CGRectContainsPoint(subViewTapped.frame, location) {

        print("tapped subview at index\(i)")
                // do your stuff here

            }
        }

    }
