If you don't want to use the whole three20 library, you can just use the EGORefreshTable Header View, which does exactly what you ask.

Facebook app use three20 library which handle the more button that you ask.

Try this library. It's very good and easy.

You can achieve such behavior by implementing scrollViewDidScroll: method of scroll view delegate. Check contentOffset.y property & if its value is less than, for instance, -30, start update.

tableWithInfo.delegate = myContoller;

...

- (void)scrollViewDidScroll:(UIScrollView *)aScrollView {
    if (aScrollView.contentOffset.y < -30) { [self startUpdate]; }
}
