override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {

您可以从菜单中删除特定的子元素，而不是删除整个菜单。

override func buildMenu(with builder: UIMenuBuilder) {
    if #available(iOS 16.0, *) {
        builder.replaceChildren(ofMenu: .lookup) { elements in
            return elements.filter { item in
                switch (item as? UICommand)?.action.description {
                case "_define:", "_translate:":
                    return false
                default:
                    return true
                }
            }
        }
    }
    super.buildMenu(with: builder)
}

_define:操作同时包含元素 * 查找 * 和 * 搜索web*。
