title: UIPageViewController turn-to-page example
body: <p>There are a couple of explanations on how <code>UIPageViewControllers</code> work, and I have read them.  I have built an app based on the approach in Neil Smyth's excellent 'iPhone iOS 6 Development Essentials" in chapter 28. It is elegant and simple.  </p>
  
  <p>It seems a relatively simple thing to add a method to this class, and a button to the main app view, to cause the <code>UIPageViewController</code> to turn to a specific page.  But I cannot quite see the beset way to do this.</p>
  
  <p>If someone could point me to the solution -- or tell me how to add a method that would I think use the provided "<code>viewControllerAtIndex:</code>" method cause the page turn i want.</p>
  
  <p>Seeing this done (exactly what code codes where) in that app would help me understand and point the way to a solution in my own app. </p>
  
  <p>thanks everyone sorry i know this should be obvious from the ansers to the likes of this question <a href="https://stackoverflow.com/questions/11334967/uipageviewcontroller-how-can-i-jump-to-a-particular-page-number">link</a> but i am not quite getting it.</p>
