Question

想在导航栏的后退按钮项上使用自己的自定义字体，这过去对我有用：

    let barButtonAttributes = [NSAttributedString.Key.foregroundColor : UIColor.pink,
                               NSAttributedString.Key.font : UIFont(name: "My-Awesome-Font", size: 18)!]
    UIBarButtonItem.appearance().setTitleTextAttributes(barButtonAttributes, for: .normal)
    UIBarButtonItem.appearance().setTitleTextAttributes(barButtonAttributes, for: .highlighted)

在iOS 13上，这对我来说已停止工作。有解决方法吗？

Answer 1

您将要研究iOS 13中新的UINavigationBarAppearance类。

在您的情况下：

let style = UINavigationBarAppearance()
style.buttonAppearance.normal.titleTextAttributes = [.font: #YOURFONT#]
style.doneButtonAppearance.normal.titleTextAttributes = [.font: #YOURFONT#]

navigationController?.navigationBar.standardAppearance = style
// You may want these as well:
navigationController?.navigationBar.scrollEdgeAppearance = ...
navigationController?.navigationBar.compactAppearance = ...
