IOS7 navigatinBar tintColor change in popover

Question

I developed iPad application. I\'m opening some screens in popover with navigation controller. But I did not change navigationcontroller tint color in IOS 7. How can I chang

Answer 1

Setting the NavigationBarStyle to UIBarStyleBlack also worked for me, but only via the Storyboard.

I tried

[[UINavigationBar appearance] setBarStyle:UIBarStyleBlack];

as well as

[[UINavigationBar appearanceWhenContainedIn:[UIPopoverController class], nil] setBarStyle:UIBarStyleBlack];

in the didFinishLaunchingWithOptions AppDelegate method. But nothing changed. Only changing the BarStyle of the NavigationControllers NavigationBar inside the Storyboard worked.
