title: UICollectionView vs UIPageViewController
body: <p>I need to have different full screen views in my app. Very similar to how snapchat works. The views should be able to communicate between each other.</p>
  
  <p>My question is: <strong>Should I use a UICollectionView with cells same size as the screen or should I use UIPageViewController?</strong></p>
  
  <p>Please provide some background info to support your opinion!</p>
