本文介绍如何定义省数组属性、模块化读取省市区字典数组、初始化数组并设置代理，实现TableView的展示及点击事件处理。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

一.

1.定义一个省数组的属性

@property(nonatomic,retain)NSMutableArray *proArr;

2.对数组初始化

-(instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

self=[super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

if (self) {

[self creatData];

}

return self;

}

3.//模块化

-(void)creatData

{

NSString *path=@"/Users/dlios/Desktop/UI08_tableView省市区字典数组/UI08_tableView省市区字典数组/area.txt";

NSString *str=[NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];

NSArray *strArr=[str componentsSeparatedByString:@"\n"];

self.proArr=[NSMutableArray array];

for (NSString *temp in strArr) {

if (![temp hasPrefix:@" "]) {

NSMutableDictionary *proDic= [NSMutableDictionary dictionary];

[proDic setObject:temp forKey:@"proName"];

NSMutableArray *cityArr=[NSMutableArray array];

[proDic setObject:cityArr forKey:@"cityArr"];

[self.proArr addObject:proDic];

}else if([temp hasPrefix:@" "] && ![temp hasPrefix:@" "]){

NSMutableDictionary *cityDic=[NSMutableDictionary dictionary];

[cityDic setObject:temp forKey:@"cityName"];

NSMutableArray *zoneArr=[NSMutableArray array];

[cityDic setObject:zoneArr forKey:@"zoneArr"];

NSMutableDictionary *proDic=[self.proArr lastObject];

NSMutableArray *cityArr=proDic[@"cityArr"];

[cityArr addObject:cityDic];

}else{

NSMutableDictionary *proDic=[self.proArr lastObject];

NSMutableArray *cityArr=proDic[@"cityArr"];

NSMutableDictionary *cityDic=[cityArr lastObject];

NSMutableArray *zoneArr=cityDic[@"zoneArr"];

[zoneArr addObject:temp];

}

for (NSMutableDictionary *prodic in self.proArr) {

NSLog(@"%@",prodic[@"proName"]);

NSMutableArray *cityArr=prodic[@"cityArr"];

for (NSMutableDictionary *citydic in cityArr) {

NSLog(@"%@",citydic[@"cityName"]);

NSMutableArray *zoneArr=citydic[@"zoneArr"];

for (NSString *name in zoneArr) {

NSLog(@"%@",name);

}

4.在ViewDidLoad里写

self.navigationController.navigationBar.translucent=NO;

UITableView *tableView=[[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height-64) style:UITableViewStylePlain];

tableView.delegate=self;

tableView.dataSource=self;

[self.view addSubview:tableView];

[tableView release];

5.签2个协议,设置代理人

<UITableViewDataSource,UITableViewDelegate>

6.UITableViewDataSource有2个必须执行的协议方法

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

return self.proArr.count;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

static NSString *reuse=@"reuse";

UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:reuse];

if (!cell) {

cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuse];

}

NSMutableDictionary *proDic=self.proArr[indexPath.row];

cell.textLabel.text=proDic[@"proName"];

return cell;

}

7.UITableViewDelegate

//tableView的点击方法

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

{

(引头文件)

LiaoNingViewController *liao=[[LiaoNingViewController alloc] init];

[self.navigationController pushViewController:liao animated:YES];

[liao release];

NSMutableDictionary *proDic=self.proArr[indexPath.row];

//省对应的市数组

NSMutableArray *cityArr=proDic[@"cityArr"];

//传市数组

liao.arr=cityArr;

}

二.创建一个市的UIViewController

1.在.h里写一条属性,用来接收传过来的市数组

@property(nonatomic,retain)NSMutableArray *arr;

2.viewDidLoad里内容同上

UITableView *tableView=[[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height-64) style:UITableViewStylePlain];
