navigation bar color not show after perform segue

I'm working on an app using Karbon Kit for paging and SWRevealViewController for sideMenu everything is working fine but I'm stuck from two hours on a strange issue. let me show you.

you can see in third image the navigationbar color is gone. i dont know where .

in my AppDelegate

[[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x339933)];
UINavigationBar.appearance.tintColor = UIColor.whiteColor;

its works for all but when i come from other ViewController to this home ViewController the bar tint is automatically changed to white. any help or any idea where i did wrong. Thanks. avoid english grammer mistakes , weekin english
