Can I localize a UIDatePicker?

I'm trying to localize a UIDatePicker. Apple's docs say that it should autodetect the current locale, yet the language stays the same, no matter what language I select. What do I have to do?

• the UIDatePicker has a locale property; if you don't set it it should default to the user's preferred locale. When you say "no matter what language I select" what do you mean--are you trying to change the locale programmatically, or are you changing the device's default locale using the Settings page?

  David Maymudes : how are you initializing the date picker? are you leaving the locale and calendar properties set to nil, or are you setting them to something?

• The locale property (and all other country specific format properties for that matter) defaults to the value returned by currentLocale, which in turns depends on the iphone's country settings, not the language settings. You need to set the appropriate country in the iphone general settings.
