title: Curve Text In UILabel Programmatically Around UIButton
body: <p>I have created a circular UIButton by setting the cornerRadius property to half of the width and height values of the UIButton.</p>
  
  <pre><code>btn.layer.cornerRadius = 75.f;
  </code></pre>
  
  <p>That works fine but I would like to also create a label for the UIButton where the label text curves around the edge of the UIButton.</p>
  
  <p>If this is even possible could somebody post a snippet of code as to how this curved text around the button edge could be accomplished?</p>
