change navigation bar title font - swift

I have a title in my navigation bar and a i want to change it to custom font. I've found this line of code, but it's for when you have a navigation controller.

self.navigationController?.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "LeagueGothic-Regular", size: 16.0)!, 
                                                             NSForegroundColorAttributeName: UIColor.whiteColor()]

But i don't have any navigation controller. I added navigation bar manually to my view.

how can i change comment font?

Try this:

Objective-C

[[UINavigationBar appearance] setTitleTextAttributes:attrsDictionary];

Swift 3

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

Swift 4

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

Proper way how to set the font for every view controller in Swift (using Appearance proxy):

Swift 5 (and 4.2)

let attributes = [NSAttributedString.Key.font: UIFont(name: "HelveticaNeue-Light", size: 17)!]
UINavigationBar.appearance().titleTextAttributes = attributes

Swift 4

let attributes = [NSAttributedStringKey.font: UIFont(name: "HelveticaNeue-Light", size: 17)!]
UINavigationBar.appearance().titleTextAttributes = attributes

Swift 3

let attributes = [NSFontAttributeName: UIFont(name: "HelveticaNeue-Light", size: 17)!]
UINavigationBar.appearance().titleTextAttributes = attributes

You can do this in Storyboard as well, there is a bug in Xcode 10.1 of doing this here is a trick to overcome this as well.

Step 1 - Choose System from Font

Step 2 - Then again choose Custom and it will show all the fonts.

SWIFT 4.x

To Change the Navigation bar title font for both Normal & Large Title above iOS 11.x

let navigation = UINavigationBar.appearance()

let navigationFont = UIFont(name: "Custom_Font_Name", size: 20)
let navigationLargeFont = UIFont(name: "Custom_Font_Name", size: 34) //34 is Large Title size by default

navigation.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white, NSAttributedStringKey.font: navigationFont!]

if #available(iOS 11, *){
    navigation.largeTitleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white, NSAttributedStringKey.font: navigationLargeFont!]
}

Large Title has to be set true in Navigation bar.

Swift 5 Easy way

//Programatically
self.navigationController!.navigationBar.titleTextAttributes = [NSAttributedString.Key.font: UIFont(name: "Helvetica Neue", size: 40)!]

Physically

Swift 5

I will show you how we do it in our company projects.

1. We create a UINavigationController subclass.
2. Write our customization code in viewDidLoad.
3. Make every navigation controller in our storyboard files inherit from it.

That is very good for more than one reason. one of the reasons is the center point of change. Once we change something in the class, all navigation controllers listen to it.

That's how our UINavigationController subclass looks.

COPY PASTE from work project.

import UIKit

class NavigationController: UINavigationController
{
    // MARK: Navigation Controller Life Cycle

    override func viewDidLoad()
    {
       super.viewDidLoad()
       setFont()
    }

    // MARK: Methods

    func setFont()
    {
       // set font for title
       self.navigationBar.titleTextAttributes = [NSAttributedString.Key.font: UIFont(name: "Al-Jazeera-Arabic", size: 20)!]
    
       // set font for navigation bar buttons
       UIBarButtonItem.appearance().setTitleTextAttributes([NSAttributedString.Key.font: UIFont(name: "Al-Jazeera-Arabic", size: 15)!], for: UIControl.State.normal)
    }
}

Swift 5

navigationController?.navigationBar.titleTextAttributes = [NSAttributedString.Key.font: UIFont(descriptor: UIFontDescriptor(name: "American Typewriter Bold", size: 36), size: 36)]

To call titleTextAttributes on the reference to the navigation bar use:

let attributes = [NSAttributedStringKey.font: UIFont(name: "Helvetica", size: 17)!]
self.navigationController?.navigationBar.titleTextAttributes = attributes

 self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.font: UIFont(name: "Lato-Semibold", size: 17)!,NSAttributedStringKey.foregroundColor : UIColor.white]

Swift 4.2 Xcode 10

self.navigationController!.navigationBar.titleTextAttributes = [NSAttributedStringKey.font: UIFont(name: "Sacramento-Regular", size: 19)!]

Be carefull, if you use custom font don't write

UIBarButtonItem.appearance().setTitleTextAttributes([NSAttributedString.Key.font: UIFont(name: "SF-Pro-Display-Medium", size: 18)!], for: UIControl.State.normal)

use font name without sumbol "-"

like this:

UIBarButtonItem.appearance().setTitleTextAttributes([NSAttributedString.Key.font: UIFont(name: "SF Pro Display Medium", size: 18)!], for: UIControl.State.normal)
