单击完成后，MPMoviePlayerController不会删除视图 [英] MPMoviePlayerController does not remove view when clicking done

问题描述

我正在创建一个MPMoviePlayerController对象，并以全屏模式流式传输视频.

I am creating a MPMoviePlayerController object and streaming a video in full screen mode.

我正在使用UIViewController来显示电影视图.

I am using a UIViewController to display the movie view.

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    //http://www.youtube.com/watch?feature=player_detailpage&v=ebeQaznNcmE
    NSURL *url = [NSURL URLWithString:@"http://a1408.g.akamai.net/5/1408/1388/2005110405/1a1a1ad948be278cff2d96046ad90768d848b41947aa1986/sample_mpeg4.mp4"];
    MPMoviePlayerController *mPlayer = [[MPMoviePlayerController alloc]initWithContentURL:url]; 
    mPlayer.view.frame = gMainView.frame;

    [[NSNotificationCenter defaultCenter] addObserver:self
                                            selector:@selector(moviePlayBackDidFinish:)
                                            name:MPMoviePlayerPlaybackDidFinishNotification
                                            object:mPlayer];
    mPlayer.shouldAutoplay = YES;
    mPlayer.controlStyle = MPMovieControlStyleFullscreen;
    [gMainView addSubview:mPlayer.view];
    [mPlayer prepareToPlay];
    [mPlayer setFullscreen:YES animated:YES];
    [mPlayer play];
}


- (void)moviePlayBackDidFinish:(NSNotification*)notification {
    int reason = [[[notification userInfo] valueForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] intValue];
    if (reason == MPMovieFinishReasonPlaybackEnded) {
        //movie finished playing
    }
    else if (reason == MPMovieFinishReasonUserExited) {
        //user hit the done button
        MPMoviePlayerController *moviePlayer = [notification object];

        [[NSNotificationCenter defaultCenter] removeObserver:self      
                                                      name:MPMoviePlayerPlaybackDidFinishNotification
                                                      object:moviePlayer];

        if ([moviePlayer respondsToSelector:@selector(setFullscreen:animated:)]) {
            [moviePlayer.view removeFromSuperview];
        }
        [moviePlayer release];
    }
    else if (reason == MPMovieFinishReasonPlaybackError) {
        //error
    }
}

单击完成后，视频画面从屏幕上移开，但控件从屏幕上移开，视图也没有从屏幕上移出.

When clicking done, the video visual is removed from the screen, but the controls are not removed from the screen and the view is not removed from the screen.

控件确实出现"//用户点击完成按钮".它确实执行了从超级视图中删除视图的代码，我通过添加日志进行了检查，但未从屏幕中删除控件，也未从屏幕中删除视图. 我在做什么错了?

The control does come to "//user hit the done button". It does execute the code to remove the view from superview, I checked by adding logs, but the controls are not removed from the screen and the view is not removed from the screen. What am I doing wrong?

如果我使用MPMoviePlayerViewController，那么它甚至都不会等我按完成".视频播放完毕后，它将自动删除视图.但是我不要.

If I use MPMoviePlayerViewController then it doesn't even wait for me to press Done. Once the video is complete it automatically removes the view. But I don' want that.

如果我删除"[mPlayer setFullscreen:是动画:是]"，那么在单击完成"时，视图将被完全删除.但是视频无法全屏显示，并且状态栏变为灰色，这也是我不想要的.

If I remove "[mPlayer setFullscreen:YES animated:YES]" then when clicking on Done, the view is removed completely. But the video is not displayed in full screen and the status bar goes gray which is again what I don't want.

推荐答案

下面的代码对我有用，希望它对您也有帮助.

The below code worked for me, Hope it helps you too.

-(IBAction)playVedio:(id)sender{
mp = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

    [[mp moviePlayer] prepareToPlay];
    [[mp moviePlayer] setUseApplicationAudioSession:NO];
    [[mp moviePlayer] setShouldAutoplay:YES];
    [[mp moviePlayer] setControlStyle:2];
    [[mp moviePlayer] setRepeatMode:MPMovieRepeatModeOne];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
    [self presentMoviePlayerViewControllerAnimated:mp];

}

-(void)videoPlayBackDidFinish:(NSNotification*)notification  {

    [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

    [mp.moviePlayer stop];
    mp = nil;
    [mp release];
    [self dismissMoviePlayerViewControllerAnimated];  
}
