swift - NSFont.TextStyleOptionKey 中可以使用哪些值

Question

我无法找到 NSFont.TextStyleOptionKey 的有效值.

更具体地说，我想使用 NSFont.preferredFont(forTextStyle:options:)具有动态(动态点大小)类型，但我想更改字体的粗细。

这些值由 XCode 中的自动完成显示:

        NSFont.Weight.black
        NSFont.Weight.heavy
        NSFont.Weight.bold
        NSFont.Weight.semibold
        NSFont.Weight.medium
        NSFont.Weight.regular
        NSFont.Weight.light
        NSFont.Weight.thin
        NSFont.Weight.ultraLight

跳转到定义命令显示:

extension NSFont.Weight {
    @available(macOS 10.11, *)
    public static let ultraLight: NSFont.Weight

    @available(macOS 10.11, *)
    public static let thin: NSFont.Weight

    @available(macOS 10.11, *)
    public static let light: NSFont.Weight

    @available(macOS 10.11, *)
    public static let regular: NSFont.Weight

    @available(macOS 10.11, *)
    public static let medium: NSFont.Weight

    @available(macOS 10.11, *)
    public static let semibold: NSFont.Weight

    @available(macOS 10.11, *)
    public static let bold: NSFont.Weight

    @available(macOS 10.11, *)
    public static let heavy: NSFont.Weight

    @available(macOS 10.11, *)
    public static let black: NSFont.Weight
}
