title: iOS 7 keep buttons at bottom in 3.5inch and 4inch
body: <p>I haven't done iOS development in a while (since Xcode 4 and iOS 5). And I have a very noobish question:</p>
  
  <p>How can I keep buttons at the bottom of a storyboard viewcontroller on both 3.5inch and 4 inch devices? Previously I could use 'origin' or something similar in the right side panel.</p>
