Customizing the UIPopoverController view background and border color
iOS 7 onwards, you can change backgroundColor of UIPopoverController which affects the navigation background color as well as arrows of popover.
@property (nonatomic, copy) UIColor *backgroundColor NS_AVAILABLE_IOS(7_0);Usage example:
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.
Unfortunately, UIPopoverController is not customizable like that. You can't change the border color, navigation bar style/color, or arrow style/color: How to customize / style a UIPopoverController.
