Re: NSString and string contains

Or if your're on Leopard using the new enumerator:

NSString *searchFor = @"home";
NSRange range;
for (NSString *string in stringList)
{
    range = [word rangeOfString:searchFor];
    if (range.location != NSNotFound)
    {
      NSLog (@"Yay! '%@' found in '%@'.", searchFor, string);
    }
}

Correct me if I'm wrong.
