问如何通过indexPath获取uitableViewCell？

EN

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex == 0)
    {
        NSInteger section =  [nowIndex section];
        NSInteger row = [nowIndex row];
        NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];
        formatter.dateFormat = @"yyyy-MM-dd";

        if (section == 0)
        {
            if (row == 0)
            {

            }
            else if (row == 1)
            {
                UILabel *content = (UILabel *)[[(UITableView *)[actionSheet ] cellForRowAtIndexPath:nowIndex] viewWithTag:contentTag];
                content.text = [formatter stringFromDate:checkInDate.date];
            }
            else if (row == 2)
            {

            }
        }
    }
}
