Kolor tekstu UINavigationBar w języku Swift

Jak mam zmienić kolor UINavigationBar W Swift?

Większość rzeczy w Internecie mówi, aby zrobić coś takiego: 

[self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];

Które przetłumaczyłem na 

let titleDict: NSDictionary = ["NSForegroundColorAttributeName": UIColor.whiteColor()]
self.navigationController.navigationBartitleTextAttributes = titleDict
//self is referring to a UIViewController
Ale to nie działa. Zmieniłem już kolory tła i przycisków, ale kolor tekstu się nie zmienia. Jakieś pomysły?

Użyj NSForegroundColorAttributeName jako klucza, a nie "NSForegroundColorAttributeName" string.

let titleDict: NSDictionary = [NSForegroundColorAttributeName: UIColor.whiteColor()]
self.navigationController.navigationBar.titleTextAttributes = titleDict

Możesz również zmienić wszystkie wygląd UINavigationController w aplikacji w pliku AppDelegate.swift. Po prostu umieść następujący kod w funkcji application:didFinishLaunchingWithOptions: 

var navigationBarAppearace = UINavigationBar.appearance()

navigationBarAppearace.tintColor = UIColor.YourNavigationButtonsColor()  // Back buttons and such
navigationBarAppearace.barTintColor = UIColor.YourBackgroundColor()  // Bar's background color

navigationBarAppearace.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.YourTitleColor()]  // Title's text color

Używam jak: 

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
      let navigationBarAppearace = UINavigationBar.appearance()
      navigationBarAppearace.titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]

     return true
   }
