#pragma mark 增加按钮的block回调
- (void)plusBtnClicked:(UIButton *)btn

#pragma mark 减少按钮的block回调

不要在 - (void)layoutSubviews 这个方法里面, 对控件进行masonry设置

- (void)layoutSubviews
{
    [super layoutSubviews];
    // 商品图标
    [_imgIcon mas_makeConstraints:^(MASConstraintMaker *make) {
        make.top.equalTo(self.contentView.mas_top).offset(10);
        make.left.equalTo(self.contentView.mas_left).offset(15);
        make.width.mas_equalTo(@66);
        make.height.mas_equalTo(@66);
    }];
}

以下是优雅的示范: .m 文件里面, 自定义一个方法 - (void)configCell:(模型*)model

#import <UIKit/UIKit.h>

@class ProductItemModel;

@interface ProductTableViewCell : UITableViewCell

- (void)configCell:(ProductItemModel *)model;
