title: How to do a semi-transparent modal segue like "Whatsapp" - "Take Photo/ Choose Existing Photo"
body: <p>My idea is to create a semi-transparent view like whatsapp does.</p>
  
  <p>1) I have a tap gesture on image view.</p>
  
  <p>2) When I tap on the image view, one layer of transparent view like whatsapp will appear</p>
  
  <p>3) I then have three button - take new, choose existing or cancel.

  <p>How do I continue from here? When I press cancel it should pop away the semi-transparent ui view..</p>
