title: UIPageViewController not showing dots
body: <p>I'm using a UIPageViewController to show two views, but I'm not getting dots at the bottom.</p>
  
  <p>Here's the code I'm using:</p>
  
  <pre><code>- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController
  { 
      if(viewController == oneViewController) {
          self.navigationController.navigationItem.title=@"Options";
          return twoViewController;
      }
      else
      {
          self.navigationController.navigationItem.title=@"All Schedule";
          return oneViewController;
      }
  } 
  
  - (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController
  {
      return 2;
  }
  </code></pre>
