xcode 6.1 iOS 8.1 NSLocale displayNameForKey NSLocaleIdentifier return nil

Question

- (NSString *)countryNameByCode:(NSString*)countryCode
{
    NSString *identifier = [NSLocale localeIdentifierFromComponents:@{NSLocaleCountryCode: countryCode}];
    NSStrin         


        

Answer 1

- (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.
