iPad中的MPMoviePlayerController全屏怪癖

我想在视图控制器中显示MPMoviePlayerController，并让用户使用默认控件切换全屏，比如YouTube应用程序。我在一个简单的示例中使用以下代码：

- (void)viewDidLoad {
    [super viewDidLoad];
    self.player = [[MPMoviePlayerController alloc] init];
    self.player.contentURL = theURL;
    self.player.view.frame = self.viewForMovie.bounds;
    self.player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    [self.viewForMovie addSubview:player.view];
    [self.player play];
}

在用户将视频设置为全屏、旋转设备并轻触屏幕之前，此功能一直运行良好。状态栏显示在错误的位置，如下面的屏幕截图所示

我正在使用iPad的模板选项卡栏应用程序。我只添加了上面的viewDidLoad、视图变量和XIB中的UIView来显示电影播放器

我做错了什么？

是shouldAutorotateToInterfaceOrientation:interfaceOrientation为所有支持的方向返回YES

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } -（布尔）应自动旋转指针面定向：（UIInterfaceOrientation）interfaceOrientation{ 返回YES； }

---

如果您提供了更多的代码，这会有所帮助。

您的UI是否使用interface builder？如果是这样，请确保在“视图属性检查器”中将视图的方向设置为“横向”。

也有同样的问题，只是花了半天时间进行整理。由于iPad是纵向的，每当我使用示例代码（或我在网上能找到的任何代码）开始一段视频时，视频和控制栏的格式都是纵向的，因此在屏幕上到处都是

不管怎么说，下面这些对我来说很有用

  /* Call the code like below:
        int iLandscape;
        if( newOrientation==UIInterfaceOrientationLandscapeLeft || newOrientation==UIInterfaceOrientationLandscapeRight )
             iLandscape=1;

        [self PlayVideo:iLandscape fullscreen:1]
    */

        if( iFullScreen==0 )
        {
            MPMoviePlayerController *player2 = 
                [[MPMoviePlayerController alloc]

            [self addSubview:player2.view];

            //play movie
            MPMoviePlayerController *player = [playerViewController moviePlayer];
            player.scalingMode=MPMovieScalingModeAspectFit;

你解决这个问题了吗

[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationPortrait animated:NO];

---

这段代码可能会帮助您。

是的，我也遇到了这个问题。这显然是MPMoviePlayerController本身的一个bug

我在应用程序中确定的解决方法是，在退出全屏模式时，自己更正状态栏：

- (void)playerDidExitFullscreen:(NSNotification *)notification {
    MPMoviePlayerController *moviePlayer = (MPMoviePlayerController *) notification.object;

    if (moviePlayer == self.player) {
        UIApplication *app = [UIApplication sharedApplication];
        if (app.statusBarOrientation != self.interfaceOrientation) {
            [app setStatusBarOrientation:self.interfaceOrientation animated:NO];
        }
    }
}

这并不能解决全屏模式下的问题，但会在之后解决

当然，请注意，该功能需要添加到通知中：

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerDidExitFullscreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];

找到了

我也有同样的问题——这就是我所做的。我建议将代码一个一个地添加到您的项目中，以了解它是如何工作的

首先，我把事情放在肖像模式上

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];

然后我把电影推到状态栏上。注意-这假设视频的纵横比为4x3

theVideo = [[MPMoviePlayerController alloc] initWithContentURL: [NSURL fileURLWithPath : path]];
float aspectRatio = (3.0f/4.0f);
float theMovieHeight = [self view].bounds.size.width * aspectRatio;
[[theVideo view] setFrame:(CGRectMake(0, [self view].bounds.size.height - theMovieHeight, [self view].bounds.size.width, theMovieHeight ))]; 

然后，在应用程序启动的地方（在我的项目中，它位于

didfinishlaunchwithoptions

函数中），无论如何，您只需要访问窗口对象

float aspectRatio = (3.0f/4.0f);
float theMovieHeight = self.window.bounds.size.width * aspectRatio;
float theSpaceAboveTheMovie = self.window.bounds.size.height - theMovieHeight;
float whereTheMovieShouldBeCentered = (self.window.bounds.size.height - theMovieHeight) / 2;

CGAffineTransform theTransform = CGAffineTransformMakeTranslation(0,0);

theTransform = CGAffineTransformScale(theTransform, 1.0f/aspectRatio, 1.0f/aspectRatio);
theTransform = CGAffineTransformTranslate(theTransform, -whereTheMovieShouldBeCentered, 0);
theTransform = CGAffineTransformRotate(theTransform, M_PI / 2);
theTransform = CGAffineTransformTranslate(theTransform, 0, -theSpaceAboveTheMovie);

[self.window setTransform:theTransform];

请记住，仿射变换是按相反的顺序进行的。因此，如果您想查看每个变换都在做什么（我建议您应该这样做），请注释掉前三个

在这里，您应该可以看到页面中央的电影和状态栏

//  theTransform = CGAffineTransformScale(theTransform, 1.0f/aspectRatio, 1.0f/aspectRatio);
//  theTransform = CGAffineTransformTranslate(theTransform, -whereTheMovieShouldBeCentered, 0);
//  theTransform = CGAffineTransformRotate(theTransform, M_PI / 2);
    theTransform = CGAffineTransformTranslate(theTransform, 0, -theSpaceAboveTheMovie);

然后是前两个

在这里，您应该看到电影和状态栏已旋转，不再居中

//  theTransform = CGAffineTransformScale(theTransform, 1.0f/aspectRatio, 1.0f/aspectRatio);
//  theTransform = CGAffineTransformTranslate(theTransform, -whereTheMovieShouldBeCentered, 0);
    theTransform = CGAffineTransformRotate(theTransform, M_PI / 2);
    theTransform = CGAffineTransformTranslate(theTransform, 0, -theSpaceAboveTheMovie);

在这里，您应该看到它旋转并居中

//  theTransform = CGAffineTransformScale(theTransform, 1.0f/aspectRatio, 1.0f/aspectRatio);
    theTransform = CGAffineTransformTranslate(theTransform, -whereTheMovieShouldBeCentered, 0);
    theTransform = CGAffineTransformRotate(theTransform, M_PI / 2);
    theTransform = CGAffineTransformTranslate(theTransform, 0, -theSpaceAboveTheMovie);

有了它们，它可以旋转并全屏显示

您可以下载我的示例代码。

试试这个

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

    [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO];
  }

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

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

    [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];


}

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

    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

对我添加到项目中的唯一代码是上面的viewDidLoad，当然还有XIB中的viewForMovie。这是iPad的默认标签栏应用程序。现在它在另一个方向上失败了。我也遇到了同样的问题。还是没有解决办法？我也是。有人知道了吗？你得到答案了吗？
