FinderSync检查是否选择了扩展名 [英] FinderSync check if extension is selected

问题描述

我正在开发FinderSync扩展名，在检查选择内容是选择还是选择/取消选择扩展名时遇到一些问题.

I am developing a FinderSync extension and I have some issues in checking if the selection is selecting, or selecting/deselecting the extension.

是否可以通过编程方式检查是否在System Preferences->Extensions中选择了FinderSync扩展名?

Is there a way to programmatically check if a FinderSync extension is selected in System Preferences->Extensions?

此选择更改时，是否有任何API会收到通知?

Are there any API's to get notified when this selection changes?

除了使用以下内容外，是否还有任何API可以选择/取消选择扩展?

Is there any API to select/deselect an extension, beside using the following?

system("pluginkit -e use -i com.mycompany.finderExt")

请注意，我已经访问了以下页面:

OSX Finder同步扩展

推荐答案

pluginkit -m -A -i com.mycompany.finderExt

如果启用了分机，呼叫将返回

If the extension is enabled, the call will return

"+ com.mycompany.finderExt(1)"

如果未启用该分机，则呼叫将返回

If the extension is not enabled, the call will return

-com.mycompany.finderExt(1)"

请注意加号和减号，只需解析返回值以确定扩展名是否已启用.

Notice the plus and minus signs, just parse the return to determine if the extension is enabled.
