推荐答案

Ben的答案在模拟器上效果很好，但在设备上不起作用，您无法在设备上的任何位置写东西.检查下面的代码

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];
