title: Display more than one video from one button
body: <p>From the page where I can select which chapter that I want, after selecting the chapter, it will show the description page. At the navigation bar, there is a Back button and a Video button.</p>
  
  <p>For every different chapter that I select, the video that is being displayed need to be different. But how do i display out 10 different videos from the Video button?</p>
  
  <p>The TableView and the description of the chapter is retrieved from database and the videos are just stored in a folder in Xcode.</p>
  
  <p>Currently, from any chapter that i press the video, the video will just appear the same.
  The codes I'm using is this:</p>
  
  <pre><code>-(IBAction)playvideo {
  
  NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
                                       pathForResource:@"example" ofType:@"mp4"]];
  
  MPMoviePlayerViewController *playercontroller = [[MPMoviePlayerViewController alloc] 
                                                   initWithContentURL:url];
  
  [self presentMoviePlayerViewControllerAnimated:playercontroller];
  
  playercontroller.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
  
  [playercontroller.moviePlayer play];
  
  playercontroller = nil;
  
  } 
  </code></pre>
