以编程方式将工作区添加/删除到mac

Question

我有一个相当简单的问题.我将如何以编程方式添加/删除任务控制中找到的工作空间.我在这里看过这篇关于以编程方式更改到另一个空间的帖子,我认为它可能类似于答案,使用CGSPrivate.h.我不需要担心私有框架,因为它不会在应用商店中出现.

编辑:我也看到一篇关于修改com.apple.spaces.plist和添加工作区的帖子,但我不知道如何添加它,因为dict有UUID和其他东西.

在 Mission Control 中，这是 Dock 的辅助功能层次结构（在我的 Mac，OS X 10.10 上）：

工作区按钮的位置是删除按钮的中间。
