appLocale = [[NSLocale alloc] initWithLocaleIdentifier: @"en_US"];
identifier = [NSLocale localeIdentifierFromComponents: [NSDictionary
dictionaryWithObject: myCountryCode
forKey: NSLocaleCountryCode]];
myDictionary = [NSLocale componentsFromLocaleIdentifier: identifier];
myCountryName = [appLocale displayNameForKey:NSLocaleCountryCode
value:[myDictionaryobjectForKey:NSLocaleCountryCode]];
// Create the currency language combination and then make our locale
NSString *currencyLocaleLanguage= [NSLocale canonicalLanguageIdentifierFromString: myCountryCode];
NSString *countryLanguage= [NSString stringWithFormat: @"%@_%@", myCountryCode, currencyLocaleLanguage];
