title: Autolayout stretched selected image for UIButton
body: <p>Creating a button in interface builder with an image for it's selected state but no image for it's default state causes said image to come out distorted when in the selected state. Turning off autolayout fixes this issue.</p>

  <p>Both buttons are the same size. The button ibAction simply toggles selected state. The grey box around the view is simply there so that I'd know where to touch to activate the button since the button has no image for it's default state.</p>

  1. Why is auto layout f'ing up how button content is displayed? 
  2. How do I get this to work in auto layout?</p>
