自定义UITableViewCell （通过XIB：每个CELL形状一样适合用XIB来创建CELL）

1，自定义CELL创建

A) 新建XIB文件，继承自UITableViewCell ，CELL设置 identify标识，用于性能优化中，将移出手机屏幕的CELL放入缓存池中的标识，这里的值必须与取出缓存池中的值一致

B）新建管理XIB的CLASS文件，此文件也要继承自UITableViewCell，

C) 对XIB和CLASS进行连线，以便可以通过CLASS对XIB中控件属性进行访问

2，思路

A) 主控制器实现Datasource的相关方法，创建CELL不再直接通过UITableViewCell创建，而是通过XIB来实现的，（XIB被哪个CLASS管理，那么主控制器加载XIB返回值就是那个CLASS类型）

B） 谁创建产生CELL？？ 谁更清楚创建CELL，就在该CLASS中定义创建CELL的方法

C）主控制器viewDidLoad方法中加载其他，主TableView有TableHeaderView和TableFooterView属性来产生头部和尾部的View，这里头尾VIEW也可以自定义XIB来实现

D）管理XIB的CLASS继承自什么类型，那么在加载该XIB后返回类型就是该CLASS的类型

3，代码（还没实现tableHeaderView的滚动图片效果）
