I don't think that NSUserDefaults has that mechanism.
Using a "scheme of my own" is how the Google Chrome web browser supports
multiple user profiles. Preferences are in Application Support. Each profile
gets a subfolder in ~/Library/Application Support/Google/Chrome/, which
contains, among many other things, a JSON "Preferences" file.
I'd also consider layering my profiles into NSUserDefaults somehow. To do
this, you'll need to do lots of digging into and out of dictionaries with key
paths such as "foo.profileName.bar". I've added a category to NSUserDefaults
which creates and removes the required subdictionaries automatically, and also
understands key path "arrays" such as {"foo", profileName, "bar"}. If you're
interested,
