The methods have different signatures, so why do I get this warning?

To overcome some rare compiler idiocy, +sharedUserDefaultsController returns a result of type (id), which means that the compiler cannot choose what -save: method you are actually calling. The solution is casting the return value of + sharedUserDefaultsController or the IMHO more readable:

NSUserDefaultsController* uc = [NSUserDefaultsController sharedUserDefaultsController]; [uc save:self]; // uc has the correct type information (NSUserDefaultsController*) and therefore works.
