上代码.h文件：

@class HBSalesPriceTypeView;
    
    typedef NS_ENUM(NSInteger,HBButtonClickType){
        HBButtonClickTypeNormal = 0,
        HBButtonClickTypeUp = 1,
        HBButtonClickTypeDown = 2,
    };
    @protocol HBSalesPriceTypeViewDelegate <NSObject>
    @optional
    //选中最上方的按钮的点击事件
    - (void)selectTopButton:(HBSalesPriceTypeView *)selectView withIndex:(NSInteger)index withButtonType:(HBButtonClickType )type;
    @end
    @interface HBSalesPriceTypeView : UIView
    @property (nonatomic, weak) id<HBSalesPriceTypeViewDelegate>delegate;
    //默认选中，默认是第一个
    @property (nonatomic, assign) int defaultSelectIndex;
    @end

.m文件

#import <objc/runtime.h>

                objc_setAssociatedObject(button, btnKey, @"1", OBJC_ASSOCIATION_ASSIGN);
            }
        }
    }
    
    #pragma mark ==========点击按钮==========
    - (void)selectClick:(UIButton *)btn{

        }
        
    }
    @end

使用方法：

- (void)viewDidLoad {
        [super viewDidLoad];
        [self.view addSubview:self.selectTypeView];
        [self.selectTypeView mas_makeConstraints:^(MASConstraintMaker *make) {
            make.top.equalTo(self.view).offset(64);
            make.height.mas_equalTo(40);
            make.left.right.equalTo(self.view);
        }];
        
        [self.view addSubview:self.tableView];
        [self.tableView mas_makeConstraints:^(MASConstraintMaker *make) {
            make.top.equalTo(self.selectTypeView.mas_bottom);
            make.bottom.equalTo(self.view);
            make.left.right.equalTo(self.view);
        }];
    }
    
    #pragma mark ==========getter==========
    -(HBSalesPriceTypeView *)selectTypeView{
        if (!_selectTypeView) {
            _selectTypeView = [[HBSalesPriceTypeView alloc]initWithFrame:CGRectMake(0, 100, SCREEN_WIDTH, 40)];
            _selectTypeView.delegate = self;
        }
        return _selectTypeView;
    }
    #pragma mark ==========代理==========
    -(void)selectTopButton:(HBSalesPriceTypeView *)selectView withIndex:(NSInteger)index withButtonType:(HBButtonClickType)type{
        if (index==100) {
            //综合
     
        }else if (index==101){
            //销量
            
        }else if (index==102){
            //价格
            
        }else if (index==103){
            //佣金
        }
        
        //请求数据
    }
