로컬 비디오는 전에 웹 비디오를 재생할 때만 재생됩니다 - AVFoundation

Question

AVFoundation을 사용하여 로컬 비디오를 재생하려고합니다. 나는 웹에서 비디오를 재생 한 다음 작동하는 로컬 비디오를 재생할 때만 여기서 무슨 일이 일어나는지 알지 못합니다. 방금 로컬 비디오를 재생하면 오류가납니다.

항목을 재생할 수 없습니다. 자산 트랙이로드되었지만 재생할 수 없었습니다.

임 여기에 파일 : /// VAR/모바일/용기/데이터/응용 프로그램/E806EC2A-2C5D-

// MPMoviePlayerController를 사용하여 비디오를 재생할 수 있습니다.

MPMoviePlayerController *movieController = [[MPMoviePlayerController alloc] init]; 
movieController.controlStyle = MPMovieControlStyleDefault;//MPMovieControlStyleNone; 
[movieController setContentURL:@"Your local Url Path"]; 
[movieController.view setFrame:CGRectMake (0,0,214,186)]; 

[self.view addSubview:movieController.view]; 
[movieController.view bringSubviewToFront:self.view]; 
[movieController prepareToPlay]; 
[movieController play];
