title: Positioning a UIView between two other views. Autolayout
body: <p>I'm using Autolayout to set up quite a lot of labels and buttons in a view. One button needs to be exactly betwwen 2 UILabels and I don't know how to accomplish that. I try to get the position on one label, the position of the other, do the math, etc. But since it's using autolayout, it turns out that the frame.origin.x property is always 0.</p>
  
  <p>So any clues on how to do that?</p>
  
  <p>thanks in advance,</p>
