Usage

CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(48.296054999999996, 31.223209000000058);
APReverseGeocoding *reverseGeocoding = [APReverseGeocoding defaultGeocoding];
APCountry *country = [reverseGeocoding geocodeCountryWithCoordinate:coordinate];

NSLog(@"%@", country.code);
NSLog(@"%@", country.shortCode);
NSLog(@"%@", country.name);
NSLog(@"%@", country.localizedName);
NSLog(@"%@", country.currencyCode);
NSLog(@"%@", country.currencySymbol);
NSLog(@"%@", country.calendar);

Output:
