iOS 13 UIBarButtonItem 字体

Question

想要在导航栏后退按钮项上使用我自己的自定义字体，这在过去对我有用：

    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 中，这对我不起作用。有解决办法吗？

Answer 1

您会想要了解 iOS 13 中新的 UINavigationBarAppearance 类。

在你的情况下：

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 = ...
