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

Question

我一直无法找到NSFont.TextStyleOptionKey.

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

XCode 中的自动完成功能显示了这些值：

        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

该jump to definition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
}
