使用：

1.直接使用

  WJViewGroup *group = [[WJViewGroup alloc]initWithFrame:CGRectMake(ScreenWidth*0.05, 20, ScreenWidth*0.9, 120)];
    group.isLine = YES;

    group.layer.borderColor = [UIColor colorWithHexString:@"d3d1d1"].CGColor;
    [group addItem:3 widthItem:3 num:@[@"美食",@"电影",@"KTV",@"龙虾",@"甜品",@"海鲜",@"火锅",@"自助餐",@"蔬菜"]];
    [group setItemBlock:^(NSInteger index) {
        NSLog(@"%ld",index);
        
    }];
    [self.view addSubview:group];

效果图：

2.cell中使用

自定义初始化cell

- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier cellHeight:(NSInteger)cellHeight; 

      _group = [[WJViewGroup alloc]initWithFrame:CGRectMake(ScreenWidth*0.05, CGRectGetHeight(viewBG.frame) +5, ScreenWidth*0.9, cellHeight)];
        _group.isLine = YES;
        if (cellHeight == 80) {
            _group.heightNum = 2;
        }
        _group.layer.borderColor = [UIColor colorWithHexString:@"d3d1d1"].CGColor;
        [_group addItem:3 widthItem:3 num:@[@"",@"",@"",@"",@"",@"",@"",@"",@""]];
        [self.contentView addSubview:_group];

懒加载：

- (NSArray *)arrayContext {
    if (!_arrayContext) {
        _arrayContext = [[NSArray alloc]initWithObjects:
  @[@"火锅",@"蛋糕甜点",@"西餐",@"自助餐",@"小吃快餐",@"香锅烤鱼",@"聚餐宴请",@"烧烤烤肉",@"日韩料理"],
  @[@"经济型酒店",@"豪华酒店",@"主题酒店",@"公寓型酒店",@"客栈",@"青年旅社"],
  @[@"美发",@"美甲",@"美容美体",@"瑜伽/舞蹈"],
  @[@"温泉",@"海洋馆",@"展览馆",@"动植物园",@"主题公园",@"水上乐园"],
  @[@"演出赛事",@"桌游/电玩",@"运动健身",@"足疗按摩",@"洗浴/汗蒸",@"4D/5D电影",],
                         nil];
    }
    return _arrayContext;
}

代理方法中：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 

    [cell.group item:self.arrayContext[indexPath.row]];
    [cell.group setItemBlock:^(NSInteger index) {
        NSLog(@"%ld",index);
        
    }];
