title: Change color of bottom border Navigation Bar iOS
body: <p>My navigation bar is clear and I need to keep the bottom bar of the border white, I tried to use this code:</p>
  
  <pre><code>[self.navigationController.navigationBar.layer setBorderWidth:2.0];
  [self.navigationController.navigationBar.layer setBorderColor:[[UIColor whiteColor] CGColor]];
  </code></pre>
  
  <p>But this makes the entire border white on all four edges white, how can I only change the bottom border?</p>
  
  <p>I thought about adding an image at the very bottom to replicate the bar but I was hoping there was an easier way to do this.</p>
