title: Transclucent navigation bar moving section header
body: <p>I am just a simple guy struggling to get a translucent navigation bar.
  I have tried to set it in appDelegate and in the spesific ViewController.
  What i end up with is this:
  Does anyone know why the section header in white is moved down? The navigation bar is not even translucent when i scroll and i can´t set a color to it. (i can set color when translucent = false)
  I have tried to set it to translucent and opaque and inferred in storyboard.(not working)</p>
  
  <p>Update:</p>
  
  <pre><code>let colorImage = imageFromColor(UIColor(red:0.22, green:0.23, blue:0.29, alpha:0.5), frame: CGRectMake(0, 0, 340, 64))
  self.navigationController!.navigationBar.setBackgroundImage(colorImage, forBarMetrics: UIBarMetrics.Default)
  self.navigationController!.navigationBar.shadowImage = colorImage
  self.navigationController!.navigationBar.translucent = true
  </code></pre>
  
  <p>The colorImage is a image i make with a rgb-uicolor. The outcome is this: <a href="http://i.stack.imgur.com/1NLiQ.png" rel="nofollow">navigation bar 2</a></p>
  
  <p>It is transclucent between the section header, but the top bar is not!</p>
