title: How do you color/customize the UIImagePickerController's Navigation Bar?
body: <p>What is the correct way to color the UIImagePickerController's nav bar?
  <br/>
  I merely tried to see the background color but I'm getting a faded color as seen in the image below; as if some view is obstructing it.</p>
  
  <pre><code>let picker = UIImagePickerController()
  picker.sourceType = type
  picker.mediaTypes = [kUTTypeImage]
  picker.delegate = self
  picker.navigationBar.backgroundColor = UIColor.redColor()
  </code></pre>
  
  <p><img src="https://i.stack.imgur.com/iMgHJ.png" alt="enter image description here"></p>
  
  <p><p>
  It appears to have some view obscuring the redColor():</p>
  
  <pre><code>(lldb) po picker.navigationBar.subviews
  2 values
   {
    [0] = 0x00007fe7bb52a890
    [1] = 0x00007fe7bb52b670
  }
  </code></pre>

  What is the correct way to create a solid color for the Navigation Bar?</p>
