title: Subview appears underneath superviews layer.border?
body: <p>I have a <code>UIView</code> in which I define it's border in the following manner:</p>
  
  <pre><code>self.layer.borderColor = [UIColor blackColor].CGColor;
  self.layer.borderWidth = 3;
  </code></pre>
  
  <p>I attach a subview to this <code>UIView</code>, and when I move the subview over the border, it goes underneath it. Is this the intended behavior? Is there anyway to make the subview go on top of it?</p>
