1。新建一个基于Navigation－based Application的工程。

2。修改原来的RootViewController.h,RootViewController.m,RootViewController.xib为MyTableViewController.h,MyTableViewController.m,MyTableViewController.xib。

3。点击MainVindow.xib，将Rot View Controller的class设置为：MyTableViewController。

4。新建文件：DetailViewController.m文件并选择自动生成.h与.xib文件，然后在DetailViewController.xib拖入一个map view控件。

5。代码：（控件与属性连接就省略了）
