ScrollViewDidScroll: by UITableViewRowAnimation?

Question

When you use UITableViewRowAnimationwhen deleting a row or adding a row, sometimes if this row is at the extreme of the table, the table scrolls.

However, even though it scrolls, it does not seem to call scrollViewDidScroll:for the delegate.

For example, I have the following code in my delegate.

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
    NSLog(@"Scrolling %f", scrollView.contentOffset.y);
}

which is called if the user scrolls. But when I delete the line:

[self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];

The method scrollViewDidScroll:is not called at all.

Is there any way to make sure this is caused when the animation UITableView?

Thank!
