Change color of Back button in navigation bar

Question

I am trying to change the color of the Settings button to white, but can\'t get it to change.

I\'ve tried both of these:

navigationItem.leftBarButton         


        

Answer 1

Swift 4.2

Change complete app theme

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.

        UINavigationBar.appearance().tintColor = .white

        return true
    }

Change specific controller

let navController = UINavigationController.init(rootViewController: yourViewController) 
navController.navigationBar.tintColor = .red

present(navController, animated: true, completion: nil)
