title: Add Hairline border to the bottom of UiToolbar in ios7
body: <p>I would like to remove the top 1px hairline display at the top, and add the 1px hairline to the bottom on a UiToolbar.</p>
  
  <pre><code>@property (strong, nonatomic) IBOutlet UIToolbar *uiToolbar;
  
  // This removes the top hairline
  uiToolbar.clipsToBounds = YES;
  
  // How do I add a bottom hairline? (Should also resize automatically from portrait and landscape.)
  </code></pre>
  
  <p>Thanks</p>
