[[NSLocale currentLocale] localeIdentifier]will give you a string that is closer to what you are looking for. For my device here in the USA, I get "en_US".

If you want a more standard looking "en-US", you can use instead [[[NSLocale currentLocale] localeIdentifier] stringByReplacingOccurrencesOfString:@"_" withString:@"-"].

, [[NSLocale currentLocale] localeIdentifier] [NSLocale componentsFromLocaleIdentifier:], NSDictionary. NSLocaleLanguageCode, NSString .

NSString *isoCode = [[NSLocale preferredLanguages] objectAtIndex:0];

This will return a 2-digit iso code for the selected language on the device. "en" for English, "de" for German, etc. Hope this helps!
