Is it possible to use the NSLocalizedString infrastructure (based on localizable.strings) with a custom-defined "localization"?
The thing is, there are some languages that have different wordings for males and females. I want to ask the user's gender on first launch and then use the appropriate phrases. Of course, both are based on the same language. I can do it with my own code but I'd rather do it the easy way if possible.
NSLocalizedString is just a macro defined in NSBundle.h
Redefine it or create a new one, for example NSGenderAwareLocalizedString to fit your needs.
With the new macro, you are free to do whatever you want: two strings files per language, one for male and one for female. Or you can define a convention to derivate the key for a localized string for a female from the key of the male localized string.
