title: -setCornerRadius not found in custom view
body: <p>I am making a custom uitableviewcell class and inside this cell I have a square label.  I would like to round the corners of the label(dateBox) using this:</p>
  
  <pre><code>[dateBox.layer setCornerRadius:4.0f];
  [dateBox.layer setMasksToBounds:YES];
  </code></pre>
  
  <p>I do this is other classes and it works fine, but for some reason in the uitableviewcell subclass, I get the warning "setCornerRadius method not found".  Does anyone know why this might be?</p>
