Usage:
1. directly use
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: @ [@ "food", @ "movie", @ "KTV", @ "Lobster", @ "dessert ", @ "seafood", @ "hot pot", @ "buffet", @ "Vegetables"]; [group setItemBlock: ^ (NSInteger index) {NSLog (@ "% ld ", index) ;}]; [self. view addSubview: group];

2. Use in cell
Custom cell Initialization
- (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];
Lazy loading:
-(NSArray *) arrayContext {if (! _ ArrayContext) {_ arrayContext = [[NSArray alloc] initWithObjects: @ [@ "hot pot", @ "cake dessert", @ "Western food", @ "buffet ", @ "snacks and fast food", @ "Toy cooked fish", @ "dinner banquet", @ "barbecue", @ "Japanese and Korean cuisine"], @ [@ "budget hotel ", @ "luxury hotel", @ "theme hotel", @ "apartment hotel", @ "Inn", @ "youth hostel"], @ [@ "Hairdressing ", @ "manicure", @ "Beauty and body", @ "yoga/dance"], @ [@ "", @ "Aquarium", @ "Exhibition Hall ", @ "dynamic Botanical Garden", @ "theme park", @ "Water Park"], @ [@ "performance events", @ "table games/video games", @ "sports and fitness ", @ "Pedicure massage", @ "bath/steam", @ "4D/5D movie",], nil];} return _ arrayContext ;}
Proxy method:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
    [cell.group item:self.arrayContext[indexPath.row]];    [cell.group setItemBlock:^(NSInteger index) {        NSLog(@"%ld",index);            }];
