iOSのアプリケーション内で録画したビデオを再生する

Question

私はチャットアプリケーションを行っています。私はwhatsappのようにビデオを再生したい。私はそれのためにMPMoviePlayerを使用していますが、私は何をアプリとしてそれをすることができません。誰かがそれをする考えがあるなら、私を助けてください。

playerViewController =[[MPMoviePlayerCont‌​roller alloc] initWithContentURL:m‌​ovie_Url]; 
playerViewController‌​.shouldAutoplay = YES; 
playerViewController‌​.view.frame = CGRectMake(0,0,self.‌​view.frame.size.width‌​, self.view.frame.size‌​.height); 
[playerViewControlle‌​r prepareToPlay]; 
[playerViewControlle‌​r play]; 
[[playerViewControll‌​er view]setCenter:CGPoi‌​ntMake(self.view.fram‌​e.size.width/2.0f, self.view.frame.size‌​.height/2.0f)]; 
[self.view addSubview:playerVie‌​wController.view];

AVAsset *avAsset = [AVAsset assetWithURL:[NSURL fileURLWithPath:movie_Url]]; 
    AVPlayerItem *avPlayerItem =[[AVPlayerItem alloc]initWithAsset:avAsset]; 
    AVPlayer *avPlayer = [[AVPlayer alloc]initWithPlayerItem:avPlayerItem]; 
    avPlayerLayer =[AVPlayerLayer playerLayerWithPlayer:avPlayer]; 
     [avPlayer seekToTime:kCMTimeZero]; 
    [avPlayerLayer setFrame:CGRectMake(0, 64, CGRectGetWidth(self.view.frame), (CGRectGetHeight(self.view.frame)-64)/2)]; 
    [avPlayerLayer setVideoGravity:AVLayerVideoGravityResizeAspectFill]; 
    [self.view.layer addSublayer:avPlayerLayer]; 
    [avPlayer play]; 

    UIButton *expandButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [expandButton setImage:[UIImage imageNamed:@"expand"] forState:UIControlStateNormal]; 
    [expandButton addTarget:self action:@selector(videoPlayFull:) forControlEvents:UIControlEventTouchUpInside]; 
    [expandButton setFrame:CGRectMake(CGRectGetWidth(self.view.frame)-40,CGRectGetMaxY(avPlayerLayer.frame)-40, 21, 21)]; 
    [self.view addSubview:expandButton];
