title: iOS - Arrange subviews in circular shape
body: <p>I have a  bunch of views in my app. I would like to arrange them in a circular shape and change their center depending on the number of views present.</p>
  
  <p>So, if there are 3 views they would look like a triangle, but would still form a circle. If there are 4 it would look like a square but still form a circle, and so on...</p>
  
  <p>In short, the centers of all views would sit on a imaginary circle.</p>
  
  <p>Any suggestions?</p>
