I just posted JJPluralForm, an adaptation for Mozilla's PluralForm.

With that, you wouldn't have to worry about doing all the if-else, switch-case code to do localizing in your code, which becomes impossible to maintain as your number of localizations grow.

Something like the example you gave could be handled with:

[[JJPluralForm sharedManager] pluralStringForNumber:numberOfObjects
                                    withPluralForms:NSLocalizedString(@"N_OBJECTS_PLURAL_STRING", @"")
                                    localizeNumeral:YES];

Each Localizable.strings file then localize N_OBJECTS_PLURAL_STRING as a semicolon separated list of plural forms. For English, that would be "%@ object;%@ objects".
