title: Playing a Downloaded Video from the Documents Directory with Cocoa-Touch
body: <p>I'm trying to get my app to play a video file that's been downloaded to the documents directory. I know the file is getting downloaded, but I can't seem to get the file to play, here is my code:</p>
  
  <pre><code>-(IBAction)play{
  
  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString *documentsDirectory = [paths objectAtIndex:0];
  NSString *path = [documentsDirectory stringByAppendingPathComponent:@"%@/piggy.m4v"];
  
  NSURL *movieURL = [NSURL fileURLWithPath:path];
  
  
  _player = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
  [self.view addSubview:_player.view];
  
  _player.controlStyle = MPMovieControlStyleDefault;
  _player.shouldAutoplay = YES;
  
  
  [_player setFullscreen:YES animated:YES];
  
  
  [_player play];
  
  }
  </code></pre>
