title: How to make scrollView 'bounce' on tap
body: <p>For example, on the iOS 7/8 lock screen, if you tap rather than drag it to the right, it will have a slight bounce effect. How can I detect the tap gesture (and not have it be confused with the dragging) and recreate a similarly subtle 'bounce' effect? Can anybody share a code example (swift/obj-c) ?</p>
  
  <p>I think this is a great way to show the user that something should be dragged rather than tapped and it doesn't require reading any small indicators.</p>
