title: Highlight Event
body: <p>I'm using an UIImageView as a button with two different images on it, one normal, and another one when the image is clicked (highlighted). I've managed to create a Tap Gesture Recognizer and link it to the image so that when I click,  highlights it and change the image, but how can I change it back to the first image when stop clicking? Should I use Long Press Gesture Recognizer?</p>
  
  <p>Thanks</p>
