objective-c - MPMoviePlayerController 控件在 UIModalPresentationFormSheet 样式模式中打开并且用户使视频全屏时

Question

在我的 iPad 应用程序中，我有一个 UIButton，它调用 IBAction 来调用 View Controller 作为模态来显示视频。我希望模态显示为 720x405，这部分看起来没问题。这是按钮正在执行的 IBAction 代码:

    -(IBAction)videoPlayerTest:(id)sender {
        VideoModalViewController *vc = [[VideoModalViewController alloc] initWithNibName: @"VideoModalViewController" bundle: nil];
        vc.fileName = @"testvideo.m4v";
        vc.modalPresentationStyle = UIModalPresentationFormSheet;
        [self presentModalViewController:vc animated: YES];
        vc.view.superview.frame = CGRectMake(0, 0, 720, 405); 
        vc.view.superview.center = self.view.center;
        [vc release];
    }

模式出现在我想要的地方，控件在 MPMoviePlayerController 上响应；慢跑栏、暂停、播放等，但如果用户点击全屏按钮，视频确实可以全屏显示，但之后 MPMoviePlayerController 将不会响应播放器控件上的任何后续点击。如果我删除 modalPresentationStyle 行它会工作，但模式出现在全屏 View 而不是我想要的 720x405 模式。我已经添加了 Observers 来尝试调整框架大小并在用户使电影 Controller 全屏并返回窗口时重新居中，但它似乎根本没有帮助。这是代码。

    - (void)willEnterFullscreen:(NSNotification*)notification {
        NSLog(@"willEnterFullscreen");
        [self setModalPresentationStyle:UIModalPresentationFullScreen];
        self.view.frame = CGRectMake(0, 0, 1024, 768);
        self.view.center = self.view.center;
    }

    - (void)willExitFullscreen:(NSNotification*)notification {
        NSLog(@"willExitFullscreen");
        [self setModalPresentationStyle:UIModalPresentationFormSheet];
        self.view.frame = CGRectMake(0, 0, 720, 405);
        self.view.center = self.view.center;
    }

    - (void)playMovie {
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willEnterFullscreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willExitFullscreen:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];

        NSString *videoString = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:fileName];
        NSURL *videoURL = [NSURL fileURLWithPath:videoString];
        moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
        [self.view addSubview:moviePlayer.view];
        moviePlayer.view.frame = CGRectMake(0, 0, 720, 405);
        moviePlayer.view.backgroundColor = [UIColor grayColor];
        [moviePlayer prepareToPlay];
        [moviePlayer play];
    }

这是我的第一篇文章——希望我做对了，并提供了有关我遇到的问题的足够信息。

我已经解决了我的问题。我不知道 MPMoviePlayerViewController，我创建了它并将其用作我的模态。效果很好。

    -(void)playVideo:(NSString *)fileName {
        NSString *videoString = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:fileName];
        NSURL *videoURL = [NSURL fileURLWithPath:videoString];
        mpViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:videoURL];
        [self presentModalViewController:mpViewController animated:NO];
        [[mpViewController moviePlayer] play];
    }

    -(IBAction)videoPlayerTest:(id)sender {
        [self playVideo:@"testvideo.m4v"];
    }

我想我会发布我的想法，以防其他人遇到同样的情况
