MPMoviePlayerController does not remove view when

2019-04-26 15:19发布

问题:

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

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
    }
}

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.

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?

EDIT:

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.

EDIT:

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.

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];  
}

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    id presentedViewController = [window.rootViewController presentedViewController];
    NSString *className = presentedViewController ? NSStringFromClass([presentedViewController class]) : nil;

    if (window && [className isEqualToString:@"AVFullScreenViewController"]) {

        return UIInterfaceOrientationMaskAll;

    } else {

        UIInterfaceOrientation interfaceOrientation = [UIApplication sharedApplication].statusBarOrientation;

        if(UIInterfaceOrientationIsPortrait(interfaceOrientation))

        {

        }

        else if(UIInterfaceOrientationIsLandscape(interfaceOrientation))

        {


        }

        return UIInterfaceOrientationMaskPortrait;

        CGRect frame = [UIScreen mainScreen].applicationFrame;
        CGSize size = frame.size;
        NSLog(@"%@", [NSString stringWithFormat:@"Rotation: %s [w=%f, h=%f]",
                      UIInterfaceOrientationIsPortrait(interfaceOrientation) ? "Portrait" : "Landscape",
                      size.width, size.height]);
    }
}
