次のコードを使用してMPMoviePlayerControllerを使用してビデオを再生していますが、ビデオが再生されません。誰か教えてもらえますか?
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"/one.mp4"];
NSString *mediaPath = [[[NSBundle mainBundle]resourcePath] stringByAppendingPathComponent:filePath];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:mediaPath]];
[[moviePlayer view] setFrame:[[self view] bounds]];
[[self view] addSubview: [moviePlayer view]];
moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
[moviePlayer play];
