问题描述
我尝试从iOS 5上的UIPopoverControler更改颜色。为此，我使用UIPopoverBackgroundView的子类，我将其分配给我的popover：
I try to change the color from a UIPopoverControler on iOS 5. To do so, I use a subclass of UIPopoverBackgroundView that I assign to my popover like this:
self.popover.popoverBackgroundViewClass = [KWPopoverBackgroundView class];
我在我的KWPopoverBackgroundView类中定义的popover现在是黑色但我的外观仍然有问题。我的popover中的navigationController的后退按钮（Medals）仍为蓝色。我希望所有的东西都是黑色的。如何摆脱这种蓝色？
My popover is now black as I defined in my KWPopoverBackgroundView class but I still have a problem with the appearance. The back button (Medals) of the navigationController inside my popover is still blue. I want everything unified in black. How do I get rid of this blue color?
我试图改变我的navigationController.navigationBar的tintColor，但当然popover不关心这个。
有没有办法在iOS 5.0中解决这个问题？ （我的应用程序在AppStore上，我不想要一个丑陋的黑客来解决这个问题）谢谢。
I tried to change the tintColor of my navigationController.navigationBar but of course the popover does'nt care about that.Is there a way to fix this in iOS 5.0 ? (My app is on the AppStore, I don't want a ugly hack to fix this) Thank you.
推荐答案
好的，我刚刚发现如何从UIPopoverController内的UINavigationController后退按钮（或其他UIBarButtonItems）更改色调颜色。
Ok, I just found how to change the tint color from the UINavigationController back button (or other UIBarButtonItems) inside the UIPopoverController.
使用UIPopoverBackgroundView，您只能更改背景和箭头图像。要更改其他项目外观，您必须使用UIAppearance，如下所示。
With UIPopoverBackgroundView you can only change background and arrow images. To change the other items appearance you have to use UIAppearance with something like the following.
// Set the UIBarButtonItem(s) inside UIPopoverController class to dark gray
[[UIBarButtonItem appearanceWhenContainedIn:[UIPopoverController class], nil]
setTintColor:[UIColor colorWithWhite:0.1f alpha:1.0f]];
