You can also look at the scroll view's setContentOffset:animated: method.

Going to the top would mean,

[self.tableView setContentOffset:CGPointZero animated:YES];

and the bottom would be,

CGFloat height = self.tableView.contentSize.height - self.tableView.bounds.size.height;
[self.tableView setContentOffset:CGPointMake(0, height) animated:YES];

You won't have control over the animation duration.

The only problem with scrollToRowAtIndexPath:atScrollPosition:animated: is that it might not be helpful when section and table headers are set.
