what are minimal requirements for iphone application to be considered localized

I need my application to be considered localized in order for MFMailComposer to present its fields in localized language. I don't need to localize any strings or xibs. W开发者_高级运维hat is the minimum I need to do in order for my application to be considered localized?

TIA

First of all localization is the process of making your app work in a specific locale or language. i.e. this usually means translating user strings and XIBs. Internationalization is making your app work properly in any locale, i.e. using NSDateFormatter etc. to format dates and times according to the user's settings.

I think MFMailComposer should use the user's currently selected locale/language to display its fields so you shouldn't have to do anything.
