title: How to create a UINavigationItem.TitleView based upon a nib file?
body: <p>I have a UINavigationController bassed sequence of screens. On one of the screens I want to replace the standard title with a custom TitleView. The custom view will be created with a nib file and will have an image and several labels.</p>
  
  <p>Do I create a UIViewController w/ associated nib file, load the nib, and assign the .view property to the TitleView? Basically, how do I use a nib where I can layout the necessary elements and then assign the resulting view to the TitleView property? </p>
