更改 UIViewAnimationTransition 背后的背景
当动画转换到另一个视图时，我使用以下代码：
[UIView beginAnimations:@"transition" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
forView:self.navigationController.view cache:NO];
[self.navigationController pushViewController:newView animated:NO];
[UIView commitAnimations];
这工作正常，但在翻转动画期间，动画后面有纯白色背景。我想知道是否有人知道更改动画背后背景颜色的简单方法。谢谢！
When animating a transition to another view I am using the following code:
[UIView beginAnimations:@"transition" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
forView:self.navigationController.view cache:NO];
[self.navigationController pushViewController:newView animated:NO];
[UIView commitAnimations];
This works fine but during the flip animation there is a solid white background behind the animation. I was wondering if anyone knows a simple way to change the color of this background behind the animation. Thanks!

它应该是
UIWindow或keyWindow.rootViewController.view的backgroundColor。将动画视图下方每个视图的
backgroundColor设置为[UIColor blackColor]应该可以解决您的问题（也不要忘记 UIWindow 的背景颜色）。It's should be the
backgroundColorof yourUIWindoworkeyWindow.rootViewController.view.Set the
backgroundColorof every view below your animated view to[UIColor blackColor]should solve your problem (don't forget the UIWindow's backgroundColor too).我认为您在动画后面看到的纯白色背景只是下面任何视图的背景颜色。只需更改该视图的背景颜色（
view.backgroundColor = [UIColor blackColor]或类似的颜色）就可以改变您在下面看到的内容。I think the solid white background you see behind the animation is just the background color of whatever view is underneath. Simply changing the background color of that view (
view.backgroundColor = [UIColor blackColor]or something like that) should change what you see underneath.
