An objective-c class to validate Spanish NIF, DNI and CIF numbers.

This class is a port of the official NIF, DNI and CIF library in Java, called "valnif", with version 2.0.1 provided by AEAT.

SLValidador *validador = [[SLValidador alloc] init];
NSInteger result = [validador vNif:@"12345678Z"];

if(result == SLValidador_NIF_OK){
  NSLog(@"Woohoo!");
}

A test application is included with a unit test, that covers every method in the class.

Include the two SLValidador.* files, located in the Library folder into your project.

#import "SLValidador.h"
