title: Reloading/changing displayed person with ABPersonViewController on iOS7
body: <p>I have a class which contains an <code>ABPersonViewController</code> child view controller. Until iOS7, I was able to pass the <code>setDisplayedPerson:</code> message several times, updating or replacing the displayed information. However, with iOS7, once the <code>viewDidLoad</code> fires for the <code>ABPersonViewController</code> child view controller, any subsequent calls to <code>setDisplayedPerson:</code> are seemingly ignored.</p>
  
  <p>I could replace the child view controller with another, and even animate the transition between them, but this is very inelegant.</p>
  
  <p>There is an open radar for this: rdar://14682982</p>
  
  <p>Anyone seen this?</p>
  
  <p><strong>Edit:</strong> The issue has been solved with iOS8 beta 1. </p>
