AVPlayerViewController沒有「完成」按鈕目標C

Question

我似乎無法在我的視頻中創建「完成」按鈕。我已附上我的代碼如下：

- (IBAction)playVideoButton:(id)sender { 

    NSString *path = [[NSBundle mainBundle] pathForResource:@"Video1" ofType:@"mp4"]; 

    NSURL *url = [NSURL fileURLWithPath:path]; 

    AVPlayer *player = [AVPlayer playerWithURL:url]; 
    AVPlayerViewController *controller = [[AVPlayerViewController alloc]init]; 
    controller.player = player; 
    //to view on full UIScreen 

    self.mc = controller; 
    controller.view.frame = self.view.bounds; 
    [self.view addSubview:controller.view]; 
    [player play];  
}

您沒有正確使用AVPlayerViewController類。這裏是你應該如何使用它：

- (IBAction)playVideoButton:(id)sender { 

    NSString *path = [[NSBundle mainBundle] pathForResource:@"Video1" ofType:@"mp4"]; 

    NSURL *url = [NSURL fileURLWithPath:path]; 

    AVPlayer *player = [AVPlayer playerWithURL:url]; 
    AVPlayerViewController *controller = [[AVPlayerViewController alloc]init]; 
    controller.player = player; 
    [self presentViewController:controller animated:YES completion:nil]; 
} 

就這樣，你就會有「完成」按鈕帶有AVPlayerViewController與其他播放按鈕（如暫停/恢復等）一起。
