I'm working on an OS X application in Cocoa and I would like to make this application multi-user aware. In other words, I want the preferences to be saved for each user in a location that only that particular user can access. Obviously, I assume this is under the home directory.

Is there a document by Apple that describes HOW this should be done - guidelines? I can't seem to find one on the developer site.

Any info would be great.

Thanks!

Check out the CFPreferences API. If you want a custom binary format for your preferences, use the Folder Manger to locate the User preference file.

Luckily for you that is the way that it works by default. Just use NSUserDefaults and that will write a file with your bundle identifier (ie com.address.program) in their ~/Library/Preferences/ directory. Of course you can also make any paths you manually define relative to the current user's home by using NSString's stringByExpandingTildeInPath.

Hope that is what you were looking for,
Jeff.
