title: Place uiview proportionally to the height, how?
body: <p>I´m trying to make an app that will look close to identical for every iPhone device? Let's say that I want to place a UIView with the distance from the top according to (view.bounds.height * (2/5)). Right now I´m edit the constraints through the code to make it work but it feels like i missing some great autolayout feature?</p>
  
  <p>Which is the best way to handle this?</p>
  
  <p>Thanks on forehand</p>
