自定义UITableViewCell （通过代码实现：每个CELL格式不一样）

1，删除自动storyboard自动产生的UIViewController，而新拖尾哦UITableViewController，并且设置该VIEW属于自定义控制器类，由于UITableViewController已经实现UITableViewDatasource和UITableViewDelegate，且设定了当前控制器类作为UITableView的代理，所以不用再写一次

2，自定义CELL继承自UITableViewCell

3，计算CELL的frame和高度只计算一次

4，两个模型对象：数据模型和数据frame模型，让数据模型作为frame模型的一个属性，控制器中对frame模型进行关联

5，自定义CELL中创建CELL, 并重写自定义CELL的init方法（初始化一次性的控件、属性等）

6，今天看了视频后，较好完成了代码的重写：
