To address Ben Packard's comment on the accepted answer, you can do this. Test if the tableView can scroll to the new position. If not, execute your method immediately. If it can scroll, wait until the scrolling is finished to execute your method.

- (void)someMethod
{
    CGFloat originalOffset = self.tableView.contentOffset.y;
    [self.tableView scrollToRowAtIndexPath:path atScrollPosition:UITableViewScrollPositionMiddle animated:NO];
    CGFloat offset = self.tableView.contentOffset.y;

    if (originalOffset == offset)
    {
        // scroll animation not required because it's already scrolled exactly there
        [self doThingAfterAnimation];
    }
    else
    {
        // We know it will scroll to a new position
        // Return to originalOffset. animated:NO is important
        [self.tableView setContentOffset:CGPointMake(0, originalOffset) animated:NO];
        // Do the scroll with animation so `scrollViewDidEndScrollingAnimation:` will execute
        [self.tableView scrollToRowAtIndexPath:path atScrollPosition:UITableViewScrollPositionMiddle animated:YES];
    }
}

- (void)scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView
{
    [self doThingAfterAnimation];
}
