在iOS 3.2(iPad)中正确显示和解除全屏mpmovieplayercontroller

以下是事件的工作方式->通知:

• 用户按“完成”按钮

  • MPMoviePlayerWillExitFullscreenNotification
  • MPMoviePlayerDidExitFullscreenNotification

• 用户在传输时按“离开全屏”按钮

  • mpmovieplayer将退出全屏通知
  • mpmovieplayerdiexitfullscreennotification(mpmovieplayerdiexitfullscreennotification)
  • 注意 播放不停止

• 电影结束了

  • MPMoviePlayerPlaybackDidFinishNotification 与 MPMoviePlayerPlaybackDidFinishReasonUserInfoKey 设置为 MPMovieFinishReasonPlaybackEnded
  • 如果你打电话 setFullscreen:NO animated:YES 在此通知中的movieplayercontroller实例上,您将获得 WillExit 和 DidExit 通知。
  • 注意,你没有得到 PlaybackDidFinish 当用户按下“完成”或“离开全屏”按钮时发出通知。

所以,通常,如果你想摆脱电影播放器的视角,你需要 [self.moviePlayerController.view removeFromSuperview] 在 DidExitFullscreen 通知处理程序。 WillExitFullscreen 太早了。

以下是我的代码:

- (void)willEnterFullscreen:(NSNotification*)notification {
    NSLog(@"willEnterFullscreen");
}

- (void)enteredFullscreen:(NSNotification*)notification {
    NSLog(@"enteredFullscreen");
}

- (void)willExitFullscreen:(NSNotification*)notification {
    NSLog(@"willExitFullscreen");
}

- (void)exitedFullscreen:(NSNotification*)notification {
    NSLog(@"exitedFullscreen");
    [self.movieController.view removeFromSuperview];
    self.movieController = nil;
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

- (void)playbackFinished:(NSNotification*)notification {
    NSNumber* reason = [[notification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
    switch ([reason intValue]) {
        case MPMovieFinishReasonPlaybackEnded:
            NSLog(@"playbackFinished. Reason: Playback Ended");         
                break;
        case MPMovieFinishReasonPlaybackError:
            NSLog(@"playbackFinished. Reason: Playback Error");
                break;
        case MPMovieFinishReasonUserExited:
            NSLog(@"playbackFinished. Reason: User Exited");
                break;
        default:
            break;
    }
    [self.movieController setFullscreen:NO animated:YES];
}

- (void)showMovie {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willEnterFullscreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willExitFullscreen:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(enteredFullscreen:) name:MPMoviePlayerDidEnterFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(exitedFullscreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playbackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

    NSURL* movieURL =  [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"tron" ofType:@"mov"]];
    self.movieController = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    self.movieController.view.frame = self.view.frame;
    [self.view addSubview:movieController.view];
    [self.movieController setFullscreen:YES animated:YES];
    [self.movieController play];
}

对。那太好了。上面确实提到了一些通知…

但是,没有mpmovieplayerplaybackwillfinishingnotification somewhy!!!! 这真是个问题。

当您将电影播放器作为模式调用时(无论以下哪种方法使用PresentViewController/PresentModalView Controller/PresentVideoController),如果您定义了它。全屏=是,则不希望调用 mpmovieplayer将退出全屏通知 通知 完全 (很明显,因为这不是一个舒适的过程,所以我们从全屏进入/退出,但只显示/关闭控制器)。

但实际上没有任何关于视频即将完成和关闭的通知。这是必要的(除了任何其他可能的情况),以抓住这个时刻,当解雇的过渡开始。(当然,转换是在 mpmovieplayerplaybackdidFinishNotification(mpmovieplayerplaybackdidFinishNotification) 叫)同时,application:supportedInterfaceOrientationsForWindow:对于之前显示的控制器,在通知之前调用,并且无法说AppDelegate必须以其他方向显示当前控制器。

所以,因为我的视频是全屏的,也没有显示任何控件(这是一种介绍,所以我只是直到它完成) 我的解决方案是用一个计时器来检查每一个短勾(0.1秒)的视频当前位置 …就快结束了,这是我自己通知的时刻。
