title: Ambiguous Layout - "Height is ambiguous for 'Image View'"
body: <p>iOS7 has really been jerking me around. </p>
  
  <p>This is a project imported from iOS6 that ran smoothly on all devices I tested on. 
  Somehow the image view pictured gets set to something like 312x400 at runtime, ignoring the specification for height that I set in the storyboard. </p>
  
  <p>I'm aware I'm missing some detail about autolayout but what gives?
  Why does the height I provided not matter at all, and why is this any different from Xcode4.x/ios6?</p>
