title: Make UIButton disappear after clicking it?
body: <p>I want after I click on a button it should disappear, but I want it that it also will be back in a few seconds. </p>
  
  <p>After I click on the button, the time should be random (something like 2 or 5 seconds) before the button will come back. </p>
  
  <p>The buttons action is <code>@IBAction func increaseCount(sender: AnyObject)</code>.</p>
