title: How do I change UIView Size?
body: <p>I have trouble with modifying my UIView height at launch.</p>
  
  <p>I have to UIView and I want one to be screen size * 70 and the other to fill the gap.</p>
  
  <p>here is what I have</p>
  
  <pre><code> @IBOutlet weak var questionFrame: UIView!
   @IBOutlet weak var answerFrame: UIView!
   let screenSize:CGRect = UIScreen.mainScreen().bounds
  </code></pre>
  
  <p>and</p>
  
  <pre><code> questionFrame.frame.size.height = screenSize.height * 0.70
   answerFrame.frame.size.height = screenSize.height * 0.30
  </code></pre>
  
  <p>It has no effect on the app during run time.
  I use autolayout but I only have margins constraints...</p>
  
  <p>Am I doing it all wrong?</p>
