PHP to iOS RegEx expression

Question

i found this cool PHP function to extract the URL name from a url string. Now i would like to recreate the same function in Objective-C code. I'm still trying but without success... Can someone help me recreate this function?

Here is the PHP code:

function __extractName($url)
{
  $domain = parse_url($url , PHP_URL_HOST);
  if (preg_match('/(?P<domain>[a-z0-9][a-z0-9\-]{1,63}\.[a-z\.]{2,6})$/i', $domain, $list)) {
    return substr($list['domain'], 0,strpos($list['domain'], "."));
  }
  return false;
}

It would help if you could describe what the function does in more detail. — Tom Harrington

Why would you even bother with this?

NSURL *exampleURL = [NSURL URLWithString:@"<.....>"];
NSString *host = [exampleURL host];
if (host) NSLog(@"host is %@", host);

That will return the hostname. If you need to do further processing, e.g. return "google" for both "google.com" and "google.co.uk", then that is just some more simple string processing.
