iPhone App Localization - English problems?
I am working on an App for iOS devices. I made it available for English (en) and German (de). That works fine with localization. Now I want to create a specified localization for German with region Luxemburg: German (Luxemburg) or de_LU. I added it into my Localizable.strings but nothing happened... I deleted the cache, I reinstall the app serval times: Nothing. He ignores that.
My iPhone is configured with the German language and Luxemburg as region.
Where is the problem? Or is it impossible to do that?
