Add/remove 工作区以编程方式更改为 mac
Add/remove workspace to mac programmatically
我有一个相当简单的问题。我将如何以编程方式add/remove 在任务控制中找到工作space。我已经看到这个 post here 关于以编程方式更改为另一个 space，我认为它可能与使用 CGSPrivate.h 的答案类似。我不需要担心私有框架，因为它不会出现在应用商店中。
编辑：我还看到了关于修改 com.apple.spaces.plist 和添加工作 space 的 post，但我不知道如何添加它，因为字典有 UUID和其他东西。
我能为您找到的最接近的解决方案是通过 apple 脚本实现此目的 - 请参阅 Ѻşeallү 在下面的回答 link:

现在让我们一步步看代码
对于删除工作区，第一种方法 removeAllWorkspaces 是起点。
此代码从 com.apple.spaces.plist 文件中获取打开的工作区数量，然后设置变量 workspacesToRemove。这个变量对于循环很重要，因为当有方法链（我这样称呼它们）时很难执行 for-loop 。
接下来，我通过执行 CGEvents 来调用打开任务控制的方法。然后我将鼠标移到屏幕的上角以确保工作区图标正确居中。
接下来，代码使用rectForWorkspaces方法确定最右侧工作区的关闭按钮的位置。
这是一个非常简单的方法，但它是所发生事情的主要部分。
它计算了任务控制中工作区所在的矩形。这是代表它计算的内容的图像：
然后我将这个矩形减去 145（工作区图标宽度），然后在弹出的关闭按钮中单击它。
这部分循环直到关闭所有工作区（1 除外）。
FWI：它被分成许多方法的原因是我可以循环回到特定的方法并在延迟后执行这些方法而不会阻塞线程。
好复杂的结束！
添加工作区更容易。
只有一种方法（openWorkspaces:(NSInteger)numberToOpen），打开任务控制，移动鼠标到位置，点击次数，直到添加完所有工作区。很简单的。
我有一个相当简单的问题。我将如何以编程方式add/remove 在任务控制中找到工作space。我已经看到这个 post here 关于以编程方式更改为另一个 space，我认为它可能与使用 CGSPrivate.h 的答案类似。我不需要担心私有框架，因为它不会出现在应用商店中。
编辑：我还看到了关于修改 com.apple.spaces.plist 和添加工作 space 的 post，但我不知道如何添加它，因为字典有 UUID和其他东西。

现在让我们一步步看代码
对于删除工作区，第一种方法 removeAllWorkspaces 是起点。
此代码从 com.apple.spaces.plist 文件中获取打开的工作区数量，然后设置变量 workspacesToRemove。这个变量对于循环很重要，因为当有方法链（我这样称呼它们）时很难执行 for-loop 。
接下来，我通过执行 CGEvents 来调用打开任务控制的方法。然后我将鼠标移到屏幕的上角以确保工作区图标正确居中。
接下来，代码使用rectForWorkspaces方法确定最右侧工作区的关闭按钮的位置。
这是一个非常简单的方法，但它是所发生事情的主要部分。
它计算了任务控制中工作区所在的矩形。这是代表它计算的内容的图像：
然后我将这个矩形减去 145（工作区图标宽度），然后在弹出的关闭按钮中单击它。
这部分循环直到关闭所有工作区（1 除外）。
FWI：它被分成许多方法的原因是我可以循环回到特定的方法并在延迟后执行这些方法而不会阻塞线程。
好复杂的结束！
添加工作区更容易。
只有一种方法（openWorkspaces:(NSInteger)numberToOpen），打开任务控制，移动鼠标到位置，点击次数，直到添加完所有工作区。很简单的。
