You can use the NSLocale API to get that information, but it isn't necessary to do what you want to do. OS X has support for localization built into the OS — all you need to do is supply the appropriate language files and the user can select which language he wants.

Answer 4

To be exact there is a change with iOS 9 and greater where [NSLocale preferredLanguages] now return - instead of only . So it's better to do:

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

if([[[UIDevice currentDevice] systemVersion] floatValue] >= 9.0) {
    languageOS = [[languageOS componentsSeparatedByString:@"-"] objectAtIndex:0];
}

NSString *language = [[NSLocale preferredLanguages] objectAtIndex:0];
NSLog(@"Language: %@", language);

output: Language: en
