How to play video from NSData

Question

I would like to know if it's possible to play a video from an NSData object... with the MPMoviePlayerController.

Solution

Ben's answer works perfectly on simulator but wont work on the device, You cannot write anywhere on the device. Check code below

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:@"myMove.mp4"];

    [videoData writeToFile:path atomically:YES];
    NSURL *moveUrl = [NSURL fileURLWithPath:path];
    player = [[MPMoviePlayerController alloc]init];
    [player setContentURL:moveUrl];
    player.view.frame = viewPlayer.bounds;
    [viewPlayer addSubview:player.view];
    [player play];

I'm wondering if there's any way to do this without writing to a file?

[[NSFileManager defaultManager] createFileAtPath:videoPath contents:videoData attributes:nil];

What are the advantages using createFileAtPath vs writeToFile?
