类似于qq联系人的tablview能够展开和收缩

在.h文件中定义三个数组和一个tablview

UITableView *listTable;
    NSMutableArray *listArray;
    NSMutableArray *proviceArray;
    NSMutableArray *statusArray;

//定义一个点击方法

-(void)ClickTheSection:(int)section;

在.m文件中使用

//先声明数组和tablview并给数组赋初值

- (void)viewDidLoad
{
    [super viewDidLoad];

listTable=[[[UITableView alloc]initWithFrame:CGRectMake(0, 70, 320, 390) style:UITableViewStylePlain]autorelease];
    listTable.showsVerticalScrollIndicator=NO;
    listTable.backgroundColor=[UIColor whiteColor];
    listTable.dataSource=self;
    listTable.delegate=self;
    [self.view addSubview:listTable];

listArray=[[NSMutableArray alloc]initWithObjects:@"河南",@"郑州",@"安阳",@"许昌",@"周口",@"南阳",@"信阳", nil];

    statusArray=[[NSMutableArray alloc]initWithObjects:@"0",@"0",@"0",@"0",@"0",@"0",@"0", nil];
