由于网络原因看不到效果，我的是左边是一个大分类的cell，右边是一个小分类的cell，小分类的支持多选然后传给上一个界面，这里传值可以用block

其实说到底就是cell增加一个手势，用这个手势判断是不是选中状态，当点击cell的时候，判断cell上面的数据（这里我是定义了一个可变数组selectArray，一进入这个页面开始加载数据时这个数组就初始化，并用数组初始化，初始化的个数为父类tableview的数组个数，在定义一个int行数据，只要点击了父类tableview就记录这个cell，如果不记录其他子类tableview相同位置也会出现选中状态）当点击的时候，如果selectArray里面没有当前cell上的数据，就追加，如果有就删除，indexPath是cell里面记录哪段哪行的，如（0-0）

我都是在.m文件中操作的

 int           lastSelectBigTableViewRow;

@property(nonatomic,strong)NSMutableArray * bigDataArray;
@property(nonatomic,strong)NSMutableArray * smallDataArray;
@property(nonatomic,strong)NSMutableArray * selectArray;

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"ID"];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"ID"];
    }
    cell.selectionStyle = UITableViewCellSelectionStyleNone;
            cell.textLabel.text = [self.smallDataArray[indexPath.row] objectForKey:@"category_name"];
            cell.textLabel.textAlignment = NSTextAlignmentLeft;
            cell.textLabel.textColor = [UIColor grayColor];
                if ([[self.selectArray objectAtIndex:lastSelectBigTableViewRow] containsObject:indexPath]) {
                    
                    cell.imageView.image = [UIImage imageNamed:@"cur-photo-blue.png"];
                }
                
                else
                {
                    cell.imageView.image = [UIImage imageNamed:@"cur.png"];
                }
                
                
                UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleChecking:)];
                [cell.imageView addGestureRecognizer:tap];
                cell.imageView.userInteractionEnabled = YES;
            return cell;
        }
    }
    return nil;
}
- (void) handleChecking:(UITapGestureRecognizer *)tapRecognizer {
    CGPoint tapLocation = [tapRecognizer locationInView:_subTableView];
    NSIndexPath *tappedIndexPath = [_subTableView indexPathForRowAtPoint:tapLocation];

    if ([[self.selectArray objectAtIndex:lastSelectBigTableViewRow] containsObject:tappedIndexPath]) {
        [[self.selectArray objectAtIndex:lastSelectBigTableViewRow]  removeObject:tappedIndexPath];
    }
    else {
        [[self.selectArray objectAtIndex:lastSelectBigTableViewRow]  addObject:tappedIndexPath];
    }
    [_subTableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:tappedIndexPath] withRowAnimation: UITableViewRowAnimationFade];
}

//这个是一个保存按钮，是我要取subView上的值传给上一个界面

- (void)saveClick{
    //self.selectArray
    NSMutableString * str = [[NSMutableString alloc] init];
    for (int i = 0; i < [self.selectArray count]; i++) {
        if ([[self.selectArray objectAtIndex:i] count] > 0) {
            //[str appendString:[[self.bigDataArray objectAtIndex:i] objectForKey:@"category_name"]];
            for (int j = 0; j < [[self.selectArray objectAtIndex:i] count]; j++) {
                NSIndexPath * path = [[self.selectArray objectAtIndex:i] objectAtIndex:j];
                NSMutableArray * tempArray = [self.bigDataArray[i] objectForKey:@"items"];
                NSDictionary * dic = [tempArray objectAtIndex:[path row]];
                [str appendString:[dic objectForKey:@"category_name"]];
                [str appendString:@","];
            }
        }
    }
    if (self.myBlock) {
        self.myBlock(str);
    }
    [self.navigationController popViewControllerAnimated:YES];
}
