仿淘宝购物订单逻辑

设计模式MVC 控制器450行代码 cell 280行代码 实现类似淘宝购物车的选择，编辑，删除等功能
    
### 选择：

关键逻辑代码：
    
    1， 点击全选按钮，更新其他按钮状态：
    
    // >!更新商里每个商品选择状态
    
    - (void)updateGoodsSelectedState
    {
        for (GoodsModel * model in self.czyGoodsList) {

model.isGoodsSelected = self.isShopSelected;
        }
    }
    
    2，点击商店更新商品状态:
    
    - (void)updateTotalBtnSelectedState:(BOOL)state
    {
        self.isShopSelected = state;

for (GoodsModel * model in self.czyGoodsList) {

model.isGoodsSelected = state;
        }
    }
    
    3, 点击商品更改商店和全选按钮状态:
    
    - (void)updateShopSeletedState
    {
        // 数量为0
        
        if (self.czyGoodsList.count == 0) {
            self.isShopSelected = NO;
            return;
        }

for (GoodsModel * model in self.czyGoodsList) {

// 一个未选中 则为未选中
            
            if (model.isGoodsSelected == NO) {
                self.isShopSelected = NO;
                return;
            }
        }

self.isShopSelected = YES;
    }

    {
        for (GoodsModel * model in self.czyGoodsList) {

model.goodEditStyle = style;
        }
