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
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;
}
效果图:
// >!更新商店内每个商品编辑状态:
- (void)updateGoodsEditState:(CzyCellStyle)style
{
for (GoodsModel * model in self.czyGoodsList) {
model.goodEditStyle = style;
}
}
效果图:
