=-= 命名有些错误，但功能实现，以后注意下命名规范

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:3widthItem:3num:@[@"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:3widthItem:3num:@[@"",@"",@"",@"",@"",@"",@"",@"",@""]];[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);
}];
