iPhone Quartz CAAnimation 中的背景

每当我使用石英动画时，动画的背景都是白色的。我怎样才能将其更改为不同的颜色。这是我用来制作动画的代码

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];

[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:superview cache:YES];
[superview addSubview:backview];
[defaultview removeFromSuperview];
[UIView commitAnimations];

Whenever I am using a quartz animation the background of the animation is white. How can I change this to be a different color. This is the code I am using to produce the animation

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];

[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:superview cache:YES];
[superview addSubview:backview];
[defaultview removeFromSuperview];
[UIView commitAnimations];

我认为这些转换的背景颜色与应用程序的一个 UIWindow 对象（其主窗口）的背景颜色相同。

您可以使用界面生成器在 nib 文件（通常称为 MainWindow.xib）中设置此颜色。

您还可以通过编程方式设置此设置，例如在应用程序委托对象的 applicationDidFinishLaunching: 方法中，通过如下方式设置：

UIColor* myColor = [UIColor blackColor];  // Or any other color you want.
[window setBackgroundColor:myColor];

顺便说一句，您还可以使用以下方法将此“颜色”设置为图像：方法，例如 colorWithPatternImage:，UIColor 的便捷构造函数之一。

参考：之前关于翻转视图背景颜色的问题。

I think the background color for these transitions is the same as the background color of your app's one UIWindow object - its main window.

You can set this color in the nib file, usually called MainWindow.xib, using interface builder.

You can also set this programmatically, such as in the applicationDidFinishLaunching: method of your app delegate object, via something like this:

UIColor* myColor = [UIColor blackColor];  // Or any other color you want.
[window setBackgroundColor:myColor];

By the way, you can also set this "color" to be an image using a method such as colorWithPatternImage:, one of the convenience constructors of UIColor.

Reference: a previous question on the flipping views background color.
