title: How to change navigation bar title in UIImagePicker?
body: <p>I'm writing in Swift, so there isn't enough info that I can find to address this.</p>
  
  <p>Anyway, I have everything working fine, i.e.: photo library selection view presented, editing works fine and cropped image gets exported to an image view.</p>
  
  <p>My problem is really when the view is presented modally, the title says "Photos". How do I change this to something else?</p>
  
  <pre><code>var imagePicker = UIImagePickerController()
  imagePicker.navigationItem.title = "MY TITLE"
  </code></pre>
  
  <p>Changing the title text attributes work, but not changing the title itself.</p>
