Answer 1

For that you would do:

id specialNavBarAppearance = [UINavigationBar appearanceWhenContainedIn:[SpecialViewController class], nil];

[specialNavBarAppearance setBarStyle:UIBarStyleBlack];
[specialNavBarAppearance setTranslucent:YES];

Answer 2

Move your changes to viewWillAppear: instead of viewDidLoad: and it should work.

Answer 3

The way you are doing it is supposed to work, but it doesn't. This does work though:

Swift 4

UINavigationBar.appearance(whenContainedInInstancesOf: [YourOtherVC.self]).tintColor = .black

Objective-C

[[UINavigationBar appearanceWhenContainedIn:[YourOtherVC class], nil] setTintColor:[UIColor blackColor]];
