title: Strange UINavigationBar behavior on iPhone 6 Plus
body: <p>I am working on a personal project and in the process of feeling out a possible navigation flow of the app.</p>
  
  <p>I am using UIPageViewController to switch between multiple view controllers.</p>
  
  <p>The issue I am seeing only happens on iPhone 6 Plus. Here is a screenshot:</p>

  <p>As you can see, when I swipe from one view controller to the "next" one, the navigation bar of the "next" view controller appears to be 20 point shorter then what it should be (status bar present). When it fully loads, the height jumps to its correct size.</p>
  
  <p>This happens only on iPhone 6 Plus and only on the initial launch.</p>
  
  <p>Any insight / help would be appreciated.</p>
