目标C-以编程方式在MacOS中获取DisplayProductID和DisplayVendorID

关于屏幕(Display)的DisplayProductID和DisplayVendorID,我可以从系统信息和终端中的几个命令中获取信息,如下所示;

显示产品名称与显示产品ID不同,它只是字符串。

$ defaults read /Library/Preferences/com.apple.windowserver.plist

            }
        )
    );
    ForceOldStyleMemoryManagement = 0;
}

但我想在MacOS应用程序中以编程方式获取这个DisplayProductID和DisplayVendorID(目标C)。

如何在Objective-C中读取此plist文件?

此文件已加密,无法获取数据。请告诉我以编程方式获取DisplayProductID和VendorID的方法。
