title: Dismiss UIAlertControllerStyleAlert UIAlertController by tapping outside
body: <p>As everyone's aware, <code>UIAlertView</code> is deprecated now and Apple wants us to use the new <code>UIAlertController</code> with the style <code>UIAlertControllerStyleAlert</code>. However, using the <code>UIAlertControllerStyleAlert</code> you cannot trigger the <code>UIAlertAction</code> with style <code>UIAlertActionStyleCancel</code> by tapping outside the alert view.</p>
  
  <p>Does anyone know of a way to dismiss the alert view by tapping outside of it?</p>
  
  <p>Cheers</p>
