Answer 1

This is a known Apple issue for iOS 8.1 simulator only - not reproducible on 8.1 devices. See below issue description from Xcode 6.1 release notes:

Localization and Keyboard settings (including 3rd party keyboards) are not correctly honored by Safari, Maps, and developer apps in the iOS 8.1 Simulator. [NSLocale currentLocale] returns en_US and only the English and Emoji keyboards are available. (18418630, 18512161).

See Xcode 6.1 Release Notes for more details.

Answer 2

Please try below code, it should work. I tried it on my device as well as simulator 8.1

- (NSString *)countryNameByCode:(NSString*)countryCode {
  return [[NSLocale systemLocale] displayNameForKey:NSLocaleCountryCode value:countryCode];
}

Answer 3

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

Answer 4

This works for me

NSLocale *currentLocale = [[NSLocale alloc] initWithLocaleIdentifier:[NSLocale currentLocale].localeIdentifier];

 for (AVSpeechSynthesisVoice *voice in [AVSpeechSynthesisVoice speechVoices]) {
            NSString *languageLocalised = [currentLocale displayNameForKey:NSLocaleIdentifier value:voice.language];
            NSLog(@"%@ displayNameForKey %@: %@", currentLocale.localeIdentifier, voice.language, languageLocalised);
 }

Answer 5

- (NSString *)countryNameByCode:(NSString*)countryCode 
{
    NSString *identifier = [[NSLocale preferredLanguages] firstObject];
    NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:identifier];
    NSString *countryName = [locale displayNameForKey:NSLocaleIdentifier value:countryCode];
    return countryName;
}

I don't understand why [[NSLocale currentLocale] displayNameForKey...] doesn't return country name in iOS 8 but the code above should resolve your problem.
