title: Adding a subview to UINavigationController then back to the first subview?
body: <p>I have a Navigation-Based app in which i added ABPeoplePickerNavigationController as a subview to my Navigation Contorller like this:
  I have saved the view before adding subview into <code>navView</code>.</p>
  
  <pre><code>ABPeoplePickerNavigationController *peoplePicker = [[ABPeoplePickerNavigationController alloc] init];
  peoplePicker.peoplePickerDelegate = self;
  
  navView = [[UIView alloc] init];
  navView = [[self.view superview] superview];
  
  [[[self.view superview] superview] addSubview:[peoplePicker view]];
  </code></pre>
  
  <p>It works fine, but when I'm done with the PeoplePicker and I want to get back to the previous view. I used this code but it doesn't work.</p>
  
  <pre><code>[[[self.view superview] superview] addSubview:navView];
  </code></pre>
  
  <p>I don't get it, I have saved the navView from the subview, now I can't bring it back?</p>
