NJOPasswordValidator *validator = [NJOPasswordValidator standardValidator];
NSArray *failingRules = nil;
BOOL isValid = [validator validatePassword:password
failingRules:&failingRules];
if (!isValid) {
for (id <NJOPasswordRule> rule in failingRules) {
NSLog(@"- %@", [rule localizedErrorDescription]);
}
}
