title: UINavigationBar custom image for iPhone 6/6+
body: <p>I have a custom image made by designer for UINavigationBar. I got 640x128 &amp; 640x88 size slices for iPhone. My questions :</p>
  
  <ol>
  <li><p>If I hide the status bar, do I use the 640x88 size or I still need to use 640x128,</p></li>
  <li><p>For iPhone 6/6+ and also iPad, I don't know how do I reuse these images as the size &amp; aspect ratio of Navigation bar is different. </p></li>
  </ol>
  
  <p>FYI, image is made using gradient of colours from top to bottom (in the Y-axis). Even if I use stretchable UIImage, how do I solve the problem of navigation bar of different heights on each device ? I need to target iOS 7 &amp; above. </p>
