not working when text start with www  #16

Its not working when we simply post website name like www.github.com

There is code written for that but ,
NSTextCheckingResult *match = [regex firstMatchInString:word options:0 range:NSMakeRange(0, [word length])];

match will be nil when word start with www so its not going into below condition

if ([tappableWord length] > 0)
        {
}

It will be great if someone can post the solution of it.

Thanks
