UIModalPresentationFullScreen - TransitionAnimation 背后的背景颜色
我目前正在构建一个通用应用程序。
用户点击按钮后，我通过以下方式在模态视图中呈现一些设置：
viewCtrl.modalPresentationStyle = UIModalPresentationFullScreen;
viewCtrl.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:viewCtrl animated:YES];
在 iPhone 和 iPad 上，两种 Transitionsstyle 看起来相同。现在的问题是，在 iPad 上，倾斜视图后面的背景是白色的。这个白色的背景看起来很丑。 在 iPhone 上它是黑色的，正如它应该的那样。
我还尝试向我的 [UIApplication window] 添加黑色背景视图，
UIView *bgView = [[UIView alloc] init];
[bgView setBackgroundColor:[UIColor blackColor]];
[window addSubview:bgView];
但这没有什么区别。
I'm currently building a universal app.
After the user taps a button, I present some settings in a modal View in the following way:
viewCtrl.modalPresentationStyle = UIModalPresentationFullScreen;
viewCtrl.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:viewCtrl animated:YES];
On the iPhone and iPad both Transitionsstyles look the same. Now the problem is, on the iPad the background, behing the tilting view, is white. This white background just looks ugly.
On the iPhone it is black, as it is supposed to be.
I also tried adding a black backgroundview to my [UIApplication window]
UIView *bgView = [[UIView alloc] init];
[bgView setBackgroundColor:[UIColor blackColor]];
[window addSubview:bgView];
but it doesn't make a difference.

我认为这就像将 UIWindow 背景颜色设置为黑色一样简单。例如，如果您在 IB 中打开 MainWindow.xib，您应该能够在那里设置背景 - 或者在 AppDelegate 中您应该能够设置 UIWindow 的背景。
I think it is as simple as setting the UIWindow background color to black. For example, if you open the MainWindow.xib in IB, you should be able to set the background there - or in your AppDelegate you should be able to set the background of the UIWindow.
