UIday1002:UITableView 2 用UITableView实现通讯录cell简单的数据移动、删除、添加功能

用UITableView实现通讯录cell简单的数据移动、删除、添加功能

作业要求：

使用tableViewController写简单通讯录

dataArray用来存放数据

创建Person类 （name tel）

实现添加 删除 移动

一个分组就行了

左button是 编辑 点编辑可以实现删除和移动

右button是 添加 点添加弹出一个页面 页面上有姓名 电话 弹出的页面左button是取消 右button是完成

以下解决方法中没有创建peison类
