Play downloaded video MPMovieController - ios

Question

So I'm using ASIHTTPRequest to download a video file from my FTP. It downloads and I get this as the directory path to the file:
/Users/Matt_Sich/Library/Application Support/iPhone Simulator/5.0/Applications/B7366FF2-7592-4ED0-ABC2-46BA111D0FF4/Documents/INWD.mp4
Ok now I want to play that video.... I would image that doing this would be easy but for some reason I can't manage to get it to work. All I get is a black view and that's it.
//NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"Park_iPod" ofType:#"mp4"]];
NSURL *url = [NSURL URLWithString:self.PathString];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];
(NOTE: self.PathString is the path to the downloaded file that I mentioned above)
It plays the video from the main bundle just fine so I'm sure that there's something wrong with the file path.

Answer 1

Once you've downloaded your file you need to use fileURLWithPath to access the file, not URLWithString
NSURL *url = [NSURL fileURLWithPath.PathString];

Answer 2

This would get you the documents directory...
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

Answer 3

moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:([NSURL fileURLWithPath : self.PathString])];
[moviePlayer setShouldAutoplay:NO];
[moviePlayer setFullscreen:YES animated:YES];
[moviePlayer setScalingMode:MPMovieScalingModeAspectFit];
// Register for the playback finished notification
[[NSNotificationCenter defaultCenter]
addObserver: self
selector: #selector(movieFinishedCallback:)
name: MPMoviePlayerPlaybackDidFinishNotification
object: moviePlayer];
// Register that the load state changed (movie is ready)
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(moviePlayerLoadStateChanged:)
name:MPMoviePlayerLoadStateDidChangeNotification
object: moviePlayer];
[self.view addSubview: moviePlayer.view];
[moviePlayer.view setFrame: self.view.bounds];
[moviePlayer prepareToPlay];
