Customizing the UIPopoverController view background and border color
提问by Mustafa
Is it possible to change the border color, navigation bar style/color, and arrow style/color of a pop over view? If so, how? If some sample code is available, then that'll be great!
是否可以更改弹出视图的边框颜色、导航栏样式/颜色和箭头样式/颜色？如果是这样，如何？如果有一些示例代码可用，那就太好了！

iOS 7 onwards, you can change backgroundColorof UIPopoverControllerwhich affects the navigation background color as well as arrows of popover.
iOS的7起，你可以改变backgroundColor的UIPopoverController影响导航的背景颜色以及酥料饼的箭头。
@property (nonatomic, copy) UIColor *backgroundColor NS_AVAILABLE_IOS(7_0);
Usage example:
用法示例：
if ([self.popoverVC respondsToSelector:@selector(setBackgroundColor:)]) { // Check to avoid app crash prior to iOS 7
self.popoverVC.backgroundColor = [UIColor greenColor];
}
Note- As of now (iOS 7.0.3), in some cases (like set color using colorWithPatternImage:), the simulator doesn't honor the color but on device it works fine.
注意- 截至目前（iOS 7.0.3），在某些情况下（例如使用 colorWithPatternImage: 设置颜色），模拟器不支持颜色，但在设备上它工作正常。

The navigation bar and tool bar inside a popover are just a standard UINavigationBar and UIToolBar, I've had success in changing their appearance just as you would with a normal nav bar or tool bar. The border however is not easily customizable.
弹出框内的导航栏和工具栏只是一个标准的 UINavigationBar 和 UIToolBar，我已经成功地改变了它们的外观，就像使用普通导航栏或工具栏一样。然而，边框不容易定制。

I try to trick it by customizing the viewcontroller inside the popover and then hiding the popover border using this code
我尝试通过自定义弹出框内的视图控制器然后使用此代码隐藏弹出框边框来欺骗它
UIView * border = [[insideViewController.view.superview.superview.superview subviews] objectAtIndex:0];
border.hidden = YES;
The app is actually still in development so I'm hoping other people will comment on this solution.
该应用程序实际上仍在开发中，所以我希望其他人对此解决方案发表评论。
