How to check whether the email is in valid format or not?

I am using the following code to check the validation of my email which is entered in the uitextfield. But it is returning true when I enter [email protected] it is not returning false. 

NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
    return [emailTest evaluateWithObject:email];

Anyone can suggest me ?

Solution

  • Don't exclude the domain m.com.com, as it's a possible subdomain of com.com (wich maybe looks strange, but is a valid - and btw. real - domain).

    If you still want to exclude all subdomains (saying: only allow one . after @) you would exclude email addresses like:

    So, you maybe don't want to exclude them.
