Can NSUserDefaults be used to read/write system preference plists?

I'm writing a small preference pane that needs to load and write a preferences plist created by the system. I know this can be done by manually loading the plist as a dictionary and going from there, but I was curious if it might be possible to use NSUserDefaults to do the job instead. It would cut the needed code down and would be more convenient if possible.

Does anyone have experie开发者_如何学Cnce with this?

You can use NSUserDefaults only with preferences for the current application, though for any user. You can use CFPreferences to change the defaults for other applications, or NSDictionary if you want to read/write the plists directly.
