title: Swift: Change UIAlertAction title on click
body: <p>How do I reference <code>self</code> from within a UIAlertAction?</p>
  
  <pre><code>refreshAlert.addAction(UIAlertAction(title: "Ok", style: .Default, handler: { (action: UIAlertAction!) in
          // self.title = String("HELLO")
          print("Handle Ok logic here")
      }))
  </code></pre>
  
  <p>I want the title of the UIAlertAction to change when it is clicked on (as well as other things). How do I reference myself in the command for what to do when clicked on?</p>
  
  <p>How do I make it where clicking on a UIAlertAction doesn't close the alert action</p>
