Given the localization directories returned by -[NSBundle localizations]
(en, es, it, nl)
and the language preferences set by the user as returned by -[NSLocale preferredLanguages]
( en, es, nl, ja, fr, de, it, pt-PT, sv, nb, fi, zh-Hans, zh-Hant, ko )
I expect all four available localizations to be returned in the preferred language order by -[NSBundle preferredLocalizationsFromArray:] (or -preferredLocalizations or -preferredLocalizationsFromArray:forPreferences:).
Instead, -preferredLocalizationsFromArray: returns only "en" as a viable source of localized resources.
Why?
The documentation for preferredLocalizationsFromArray:
says
Returns one or more localizations from the specified list that a bundle object would use to locate resources for the current user.
I guess it's one and not or more.
You should probably file a bug about it.
