title: Custom UIView to display video
body: <p>Hey All,
  Im working on an app for the iPad and Ive run across an issue that I need some guidance on. I have an app that uses the TabBarController. The TabBarController contains 4 UIViewController...one for each screen in the app. On each of these 4 screens, there are 4 tiles that need to act as buttons and play a video when clicked. I would like to play the video in a view that hovers over the rest of the screen and is dismissed if the user touches anywhere outside the playing video.</p>
  
  <p>My question is: How do I go about implementing the custom view to play the video? It seems to me that it should be just another view with a viewController...but I dont know if that is the correct way to go about this. Also, how do I get it to play the right video depending on what button was clicked? 
  Any advice is greatly appreciated.
  Thanks 
  Alex</p>
