change navigation bar title font - swift
提问by Hos Ap
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.
我的导航栏中有一个标题，我想将其更改为自定义字体。我找到了这行代码，但它适用于您有导航控制器的情况。
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.
但我没有任何导航控制器。我手动将导航栏添加到我的视图中。

To Change the Navigation bar title font for both Normal & Large Title above iOS 11.x
更改iOS 11.x 以上的普通标题和大标题的导航栏标题字体
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.
必须在导航栏中将大标题设置为 true。

I will show you how we do it in our company projects.
我将向您展示我们如何在公司项目中做到这一点。
- We create a
UINavigationControllersubclass. - Write our customization code in
viewDidLoad. - Make every navigation controller in our storyboard files inherit from it.
- 我们创建一个
UINavigationController子类。 - 在
viewDidLoad. - 使故事板文件中的每个导航控制器都继承自它。
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.
这很好，原因不止一个。原因之一是中心点的变化。一旦我们更改了类中的某些内容，所有导航控制器都会监听它。
That's how our UINavigationControllersubclass looks.
这就是我们的UINavigationController子类的样子。
COPY PASTE from work project.
从工作项目复制粘贴。
import UIKit
class NavigationController: UINavigationController
{
// MARK: View 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)
}
} // end of class
Good luck.
祝你好运。
