问题描述
我有一个相当简单的问题.我将如何以编程方式添加/删除在任务控制中找到的工作区.我在此处看到了有关以编程方式更改为另一个空间的信息，我认为使用CGSPrivate.h可能与答案类似.我不需要担心私有框架，因为它不在应用商店中.
I have a fairly simple question. How would I programmatically add/remove the workspaces found in mission control. I have seen this post here about changing to another space programmatically, and I think that it could be something similar to the answer, using CGSPrivate.h. I don't need to worry about private frameworks, as it's not going on the app store.
我还看到了有关修改com.apple.spaces.plist并添加工作区的帖子，但是我不知道如何添加，因为该字典包含UUID和其他内容.
I also saw a post about modifying the com.apple.spaces.plist and adding workspaces, but I have no Idea how I would add that, as the dict has UUID and other things.
推荐答案
在任务控制中，这是Dock的可访问性层次结构(在我的Mac上为OS X 10.10):
While in Mission Control this is the Accessibility Hierarchy of Dock (on my Mac, OS X 10.10):
Role Position Title Value Description
AXList 632.000000, 1136.000000 (null) (null) (null)
AXDockItem 636.300049, 1138.000000 Finder (null) (null)
AXDockItem 688.300049, 1138.000000 Firefox (null) (null)
…
AXDockItem 1231.699951, 1138.000000 Trash (null) (null)
AXGroup 0.000000, 0.000000 (null) (null) (null)
AXGroup 20.000000, 227.000000 (null) (null) exposéd windows
AXList 0.000000, -2.000000 (null) (null) (null)
AXButton 592.000000, 20.000000 Desktop 1 (null) select Desktop 1
AXButton 864.000000, 20.000000 Desktop 2 (null) select Desktop 2
AXButton 1136.000000, 20.000000 Desktop 3 (null) select Desktop 3
AXButton 1824.000000, 20.000000 (null) (null) add desktop
工作区按钮的位置位于删除"按钮的中间.
The location of the workspace buttons is the middle of the remove button.
我的测试应用:
