Facebook Graph API - how to get user country?

Question

I\'m developing a Facebook application using their Graph API. I have previously developed an app using the deprecated REST API.

I\'ve come across a problem in that

You should try like this:

/* make the API call */
[[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection,
                                                           NSDictionary *user,
                                                           NSError *error)
    {
        if (!error)
        {
            self.countryName    = [[[user objectForKey:@"location"] valueForKey:@"name"] componentsSeparatedByString:@", "][1];
            self.countryCode    = [self getCountryCodeForCountry:STUser.countryName];
        }
}];

-(NSString *)getCountryCodeForCountry:(NSString*)country
{
    NSMutableArray *countries = [self getCountries];
    NSArray *countryCodes = [NSLocale ISOCountryCodes];

    NSDictionary *codeForCountryDictionary = [[NSDictionary alloc] initWithObjects:countryCodes forKeys:countries];

    return [codeForCountryDictionary objectForKey:country];
}

+(NSMutableArray *)getCountries
{
    NSMutableArray *countries = [NSMutableArray array];

    NSArray *countryCodes = [NSLocale ISOCountryCodes];
    countries = [NSMutableArray arrayWithCapacity:[countryCodes count]];

    for (NSString *countryCode in countryCodes)
    {
        NSString *identifier = [NSLocale localeIdentifierFromComponents:[NSDictionary dictionaryWithObject: countryCode forKey: NSLocaleCountryCode]];
        NSString *country = [[NSLocale currentLocale] displayNameForKey: NSLocaleIdentifier value: identifier];
        [countries addObject: country];
    }

    return countries;
}
