title: How to rotate UIAlertController in Swift
body: <p>I have a working <code>UIAlertController</code>, but I want to rotate the <code>alert.view</code> by 90 degrees left.</p>
  
  <p>How can I do it? My code is here below:</p>
  
  <pre><code>let alert = UIAlertController(title: "", message: "Message Sample", preferredStyle: .Alert)
  alert.addAction(UIAlertAction(title: "Okay", style: .Default){(action)-&gt;() in })
  presentViewController(alert, animated: true) {}
  </code></pre>
  
  <p>I tried to add:</p>
  
  <pre><code> alert.view.transform = CGAffineTransformMakeRotation(CGFloat(M_PI_2))
  </code></pre>
  
  <p>but it doesn't work.</p>
  
  <p>Thank you !</p>
