ios - swift: 导航栏标题字体

Question

在 AppDelegate.swift 我有以下代码:

let nav1 = UINavigationController()
    let mainView = ViewController(nibName: nil, bundle: nil) //ViewController = Name of your controller
    nav1.viewControllers = [mainView]
nav1.navigationBar.topItem?.title = "JT"
    nav1.navigationController?.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "AvenirNext-UltraLight", size: 24)!,  NSForegroundColorAttributeName: UIColor.whiteColor()]

但是最后一行没有改变导航栏标题的字体我该怎么办？

Answer 1

您可以通过 Storyboard 更改导航栏标题属性或试试这个:

nav1.navigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "AvenirNext-UltraLight", size: 24)!,  NSForegroundColorAttributeName: UIColor.whiteColor()]
