Question

¿Cómo cambio la fuente NavigationBar en Swift?

Esto es lo que he intentado hasta ahora, pero he recibido un error (he implementado CaviarDreams correctamente en el proyecto):

self.navigationController.navigationBar.titleTextAttributes = NSFontAttributeName[UIFont .fontWithName(CaviarDreams.ttf, size: 20)]

El error dice: Use of unresolved identifier ''CaviarDreams

Lo siento si la pregunta es extremadamente mala.

Answer 1

Ahora tiene que desenvolver (!) Primero, ¿no es de tipo UIFont? :

self.navigationController.navigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "<font-name>", size: <size>)!]

Answer 2

Para Swift 2.3

self.navigationController!.navigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Roboto-Bold", size: 20.0)!, NSForegroundColorAttributeName : UIColor.whiteColor()];

Answer 3

Prueba esto:

self.navigationController.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "CaviarDreams", size: 20)!]

Editar: Ahora, UIFont debe ser desenvuelto para poder ser utilizado aquí.

Answer 4

Swift 2.0:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        UINavigationBar.appearance().titleTextAttributes = [
            NSFontAttributeName: UIFont(name: "Arial-Regular", size: 30)!
        ]

        return true
    }

O

 override func viewDidLoad() {
  super.viewDidLoad()

  self.navigationController?.navigationBarHidden =  false
  self.title = "SAMPLE"

//Set Color
  let attributes: AnyObject = [ NSForegroundColorAttributeName: UIColor.redColor()]
  self.navigationController!.navigationBar.titleTextAttributes = attributes as? [String : AnyObject]


//Set Font Size
  self.navigationController!.navigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Arial", size: 37.0)!];

 }

Answer 5

Usando Swift, agregué esto a AppDelegate.swift en

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

        UINavigationBar.appearance().titleTextAttributes = [
            NSFontAttributeName: UIFont(name: "DINNextLTW04-Regular", size: 20)!
        ]

        return true
    }

¡Espero eso ayude!

Answer 6

Swift 4.2

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { // Override point for customization after application launch. let font = UIFont(name: "FontName", size: 16) ?? UIFont.systemFont(ofSize: 16) UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.font: font] }

Answer 7

Swift 4

if let font = UIFont(name: "FontName", size: 16) {

 self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.font: font]

}

O como la otra respuesta recomendada hacerlo en AppDelegate:

  if let font = UIFont(name: "FontName", size: 16) {

    UINavigationBar.appearance().titleTextAttributes = [
          NSAttributedStringKey.font: font]

}
