you need to call the appearance method on the UINavigationBar class and assign that to a variable.

UINavigationBar *appearance = [UINavigationBar appearance];

this is covered at 1:45 of this video

for more information on the UIAppearance protocol see the documentation

navigationBarAppearance.barTintColor = [UIColor colorWithWhite];

appearance.tintColor = [UIColor whiteColor];
