title: How to remove the bottom gap of UIPageViewController
body: <p>I am using UIPageViewController to show images full screen, the UIViewController which is added to UIPageController as a sub view / child has the images being showed using ImageView. 
  Problem is the images arent comming fullscreen, instead the pagecontrol view's donts are appearing at the bottom and that space is completely wasted. Please check the image attached.</p>
  
  <p><img src="https://i.stack.imgur.com/pihO2.png" alt="enter image description here"></p>
  
  <p>Here is the code </p>
  
  <pre><code>self.pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];
  
  self.pageController.dataSource = self;
  [[self.pageController view] setFrame:[[self view] bounds]];
  
  NewsItemViewController *initialViewController = [self viewControllerAtIndex:0];
  
  NSArray *viewControllers = [NSArray arrayWithObject:initialViewController];
  
  [self.pageController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
  
  [self addChildViewController:self.pageController];
  [[self view] addSubview:[self.pageController view]];
  [self.pageController didMoveToParentViewController:self];
  </code></pre>
  
  <p>Here NewsItemViewController is UIViewController showing images and some text and The MainViewController implements UIPageViewControllerDataSource protocol and necessary methods in MainViewController.</p>
  
  <p>I believe there has to be a way to do show the things in full screen.</p>
  
  <p>*** Also the MainViewController is a part of a storyboard if that matters.</p>
