Why does NSUserDefaults provide method stringForKey but not a method

This does not seem symmetric.
I'm using setObject:forKey when saving a NSString to the defaults
database. Is this correct?
Yes. setObject:forKey: is for values that are objects -- not just
NSString but NSNumber, NSDate, and the other classes mentioned in the
method's documentation. Notice the other setXXX:forKey: methods take
values that are not objects.
Going in the other direction, the reason there are stringForKey:,
dateForKey:, etc. methods is that you might want to use stringForKey:
(for example) even if you originally put an integer/date/float/etc.
into the user defaults, or vice versa.
