In my didFinishLaunchingWithOptions method, i set my navigation bar tint color like that;
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
and my all back buttons and other buttons color is white which are on navigationBar. However, on iPhone 5s device and 64-bit simulator, color become gray. Also it is gray when i launch Facebook or Twitter. Is that iOS 7.1 bug on 64-bit or am i set it wrong way?
