title: How to fix titleView being masked to navigation bar during transition?
body: <p>In my view controller I am setting the <code>titleView</code> to a <code>UIView</code> which contains a <code>UIImageView</code> which is made into a circle using setCornerRadius on its layer. </p>
  
  <p>The top half of the circle is positioned over the navbar, and the bottom half over the view, like this: </p>

  <p>Now when I push this view controller, as it animates in, the bottom half of the circle is cut off until the animation completes. Only the part that's <em>in</em> the navbar is shown, something like this: </p>
  
  <p><img src="https://i.stack.imgur.com/klqVy.png" alt="B"></p>
  
  <p>As soon as the push animation ends, the full circle is shown. Is there any way I can stop the navigation bar from masking/cutting off the <code>titleView</code> while the animation takes place, so that the full circle is shown during the animation?</p>
