UITableview Cell animation

If I am inserting one by one row then this animation is working from bottom to top animation. and make a condition when you scroll top to bottom at that time not animation, but I want to also stop animation after one time animation from bottom to top.

in willDisplayCell of tableview method :

if (tempIndex == nil)
{
    CGRect myRect = [tableView rectForRowAtIndexPath:indexPath];

    //instead of 568, choose the origin of your animation
    cell.frame = CGRectMake(cell.frame.origin.x,
                            cell.frame.origin.y + 568,
                            cell.frame.size.width,
                            cell.frame.size.height);

    [UIView animateWithDuration:0.3 delay:0 options:UIViewAnimationOptionCurveEaseInOut animations:^{
        //instead of -30, choose how much you want the cell to get "under" the cell above
        cell.frame = CGRectMake(myRect.origin.x,
                                myRect.origin.y ,
                                myRect.size.width,
                                myRect.size.height);

    } completion:^(BOOL finished){
        [UIView animateWithDuration:0.3 animations:^{
            cell.frame = myRect;
        }];

    }];
    tempIndex = indexPath;
}
else if (tempIndex.row < indexPath.row)
{
    CGRect myRect = [tableView rectForRowAtIndexPath:indexPath];

    //instead of 568, choose the origin of your animation
    cell.frame = CGRectMake(cell.frame.origin.x,
                            cell.frame.origin.y + 568,
                            cell.frame.size.width,
                            cell.frame.size.height);

    [UIView animateWithDuration:0.3 delay:0 options:UIViewAnimationOptionCurveEaseInOut animations:^{
        //instead of -30, choose how much you want the cell to get "under" the cell above
        cell.frame = CGRectMake(myRect.origin.x,
                                myRect.origin.y,
                                myRect.size.width,
                                myRect.size.height);

    } completion:^(BOOL finished){
        [UIView animateWithDuration:0.3 animations:^{
            cell.frame = myRect;
        }];

    }];
    tempIndex = indexPath;
}
else
{
    tempIndex = indexPath;
}
