If you add the label to the class, you can do a hit-test on your view in the touch event with:

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
  UITouch *touch = [[event allTouches] anyObject];
  if (CGRectContainsPoint([self.site frame], [touch locationInView:self.view]))
  {
    NSURL *target = [[NSURL alloc] ...];
    ...
  }
}

Also, don't forget to release the URL you allocate (otherwise you are leaking).
