iphone UITableView及UIWebView的使用

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）

第一个页面的代码：

MyTableViewController.h

#import <UIKit/UIKit.h>

@interface MyTableViewController : UITableViewController {

NSMutableArray *listData;//表格第一部分的数据
NSMutableArray * twolistData;//表格第二部分的数据
}

@property(nonatomic,retain) NSMutableArray *listData;
@property(nonatomic,retain) NSMutableArray *twolistData;

@end

MyTableViewController.m

#import "MyTableViewController.h"

#import "DetailViewController.h"

@implementation MyTableViewController

@synthesize twolistData;

#pragma mark View lifecycle

//设置标题和初始化表格数据

self.title = @"第一个页面";

}
#pragma mark -
#pragma mark Table view data source

// 设置表格为两个部分

}
//设置每个部分的标题
