Question

I implemented the following code. It is accepting any type of mail id’s. Example: [e-mail]. But I want to accept the perfect mail id’s.Example :[e-mail],[e-mail]. Can any one guide how to do this.

- (BOOL) validateEmail: (NSString *) candidate {
    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:candidate];
}

Thanks in advance

Try out this code:

- (BOOL) validateEmail: (NSString *) candidate {
    NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}"; 
    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex]; 
    
    BOOL result = [emailTest evaluateWithObject:candidate];
    if(result)
    {
        NSSet *domains= [NSSet setWithObjects:@"yahoo.com",@"yahoo.co.in",@"yahoo.co.au",@"yahoo.co.nz",@"gmail.com",@"rediffmail.com",.........., nil];
        NSArray *arrayObjects = [domains allObjects];
        BOOL results = NO;
              for(int i = 0;i<[arrayObjects count];i++)
              {
                  if([emailTest rangeOfString:[arrayObjects objectAtIndex:i]].location != NSNotFound)
                  {
                      results = YES;
                      break;
                  }
              }
          return results;
    }
    else
    {
        return NO;
    } 
    return [emailTest evaluateWithObject:candidate];
}
