title: Adding a segmented control to the center of UINavigationBar
body: <p>I am trying to add a <code>UISegmentedControl</code> to the middle of a <code>UINavigationBar</code> of only one view (not the entire view controller). How can I go about doing this?</p>
  
  <p>Other answers I read only allow an entire view controller to contain a <code>UINavigationItem</code> as the title. I need it to show only on one view.</p>
