全屏模式下的 MPMoviePlayer 叠加层 (iPad)

发布于 2024-09-29 09:54:24 字数 518 浏览 0 评论 0原文

我想在全屏播放时在视频播放器上添加一个按钮。我在我的视频播放器上创建了一个叠加层，它在 iPhone 上运行得很好。我在 iPad 上尝试了同样的操作，但按钮从未出现。

这是我的代码：

 NSArray *windows = [[UIApplication sharedApplication] windows];
 if ([windows count] > 1){
       UIWindow * moviePlayerWindow = [windows objectAtIndex:1];
       NSArray * subviews = [moviePlayerWindow subviews];
       UIView * videoView = [subviews objectAtIndex:0];
       [videoView addSubview:myButton];
}

看起来 ipad 没有为全屏模式创建 UIWindow。

有人知道我该怎么做吗？

谢谢！

I want to add a button on my video player when it is playing in fullscreen. I created an Overlay on my videoplayer and it's working very well on an iPhone. I tryed to same thing on a iPad, but the button never appear.

Here's my code :

 NSArray *windows = [[UIApplication sharedApplication] windows];
 if ([windows count] > 1){
       UIWindow * moviePlayerWindow = [windows objectAtIndex:1];
       NSArray * subviews = [moviePlayerWindow subviews];
       UIView * videoView = [subviews objectAtIndex:0];
       [videoView addSubview:myButton];
}

It seams like the ipad dosen't create a UIWindow for the fullscreen mode.

Anyone have any idea on how I could do this?

Thanks!

几周前我找到了这个问题的解决方案：

看来这个方法在 iPad 上不起作用（我还没有检查过 iPhone SDK 4>），所以为了解决这个问题，你可以执行以下操作。

添加视频并设置为全屏后，您可以将控件直接添加到 UIWindow（例如 [[[[UIApplication sharedApplication] windows] objectAtIndex:0] addSubView:myView]），然后它们将显示在视频视频的顶部。

我发现的唯一问题是它们不遵守视图的方向规则，并且我必须在视图的 willRotateToInterfaceOrientation 方法中手动编写旋转代码。

@tigermain 的解决方案有效。

[[[[UIApplication sharedApplication] windows] objectAtIndex:0] addSubView:myView]

但是添加到窗口的视图不遵循方向。

方向的解决方案是使用 NSNotificationCenter、UIApplicationDidChangeStatusBarOrientationNotification。

    // assign a notification
    id center = [NSNotificationCenter defaultCenter];
    [center addObserver:self
             selector:@selector(didRotate:)
                 name:UIApplicationDidChangeStatusBarOrientationNotification
               object:nil];

    // this method will get called when the orientation changes
    -(void) didRotate:(NSNotification*)notification {

        UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
        NSLog(@"%d", orientation);
        // ... transform view accordingly to the enum 'UIInterfaceOrientationXXX'
    }

The solution from @tigermain works.

[[[[UIApplication sharedApplication] windows] objectAtIndex:0] addSubView:myView]

But the views added to the window do not follow the orientation.

Solution for the orientation is to use NSNotificationCenter, UIApplicationDidChangeStatusBarOrientationNotification.

    // assign a notification
    id center = [NSNotificationCenter defaultCenter];
    [center addObserver:self
             selector:@selector(didRotate:)
                 name:UIApplicationDidChangeStatusBarOrientationNotification
               object:nil];

    // this method will get called when the orientation changes
    -(void) didRotate:(NSNotification*)notification {

        UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
        NSLog(@"%d", orientation);
        // ... transform view accordingly to the enum 'UIInterfaceOrientationXXX'
    }
