购物车（问题记录）

根据项目需求。理解成不需要全选按钮，选中，不需要记录。实时计算，重复商品+1

定制xib的cell。

block有二个方法，加和减。

为啥写这篇，原因这次把自己坑怕了。

一开始是找了二个demo，一个是有选择的购物车，一个是类似淘宝购物车的demo，当然肯定不够完善，需要自己修改，后来看了一眼需求，好吧，这二个都用不到。so自己写了下，代码比较杂，比较多。

主要碰到的问题

第一个，也是最坑自己的：tableview返回cell代理方法不执行，都返回个数了，就是不返回cell。搜索了很多，大致好像七个答案，一个个是过去。最后还是没有呢，我就想是不是数据没同步？加载延迟0.5秒，ok。问题在于写在block的回调里面，所以reloaddata也要放在里面。以前还真的没注意。

第二个是啥呢，cell上处理键盘，我记得有个第三方库的，忘了用，结果就比较坑了，一开始是在写在cell里，后面才改到vc。

第三个是处理键盘下去计算价格，cell上的textfiled通过一直改变字的那个代理方法，得到cell。在手势里再调用cell的方法。

其他一些小问题。还有一点问题还没处理好。先记录下，先贴下大概代码。
