TaoBaoDetail 代码
前段时间公司在研发一个电商项目，趁现在有时间把其中的知识点整理整理。
项目的商品详情页面当时是仿制淘宝的，用到的第三方库是MJRefresh，上拉操作和下拉操作的刷新效果是把MJRefresh刷新效果从新建个分类封装了一下，感谢杰哥！！！
基本思路：
1、设置一个 UIScrollView 作为视图底层，并且设置分页为两页
2、然后在第一个分页上添加一个 UITableView 并且设置表格能够上提加载（上拉操作即为让视图滚动到下一页）
3、 在第二个分页上添加一个 UIScrollView 并且设置能有下拉刷新操作（下拉操作即为让视图滚动到上一页）
4、第二个分页UIScrollView添加子UIView，一般式商品的图文详情、产品参数、店铺等
5、Demo只提供简单的思路，项目具体实现基本相同
/** 封装刷新 MJRefresh */
#import "QRG_MJRefreshAutoFooter.h"
#import "QRG_MJRefreshNormalHeader.h"
#import "CollectionViewCell.h"
#define WIDTH [UIScreen mainScreen].bounds.size.width
#define HEIGHT [UIScreen mainScreen].bounds.size.height
#define ARCCOLOR (arc4random() % 255/256.0)
#import "ViewController.h"
