iOS UITableView , UITableViewController ，UITableViewCell实现全国各省市遍历，选择相应的地区

我们先看一下效果





代码如下

首先是第一个页面

rootTableViewController.h

#import <UIKit/UIKit.h>
#import "cityTableViewController.h"
@interface rootTableViewController : UITableViewController
@property(nonatomic,strong)NSArray *arr;
@end

rootTableViewController.m

#import "rootTableViewController.h"

@interface rootTableViewController ()
@end

@implementation rootTableViewController

- (void)viewDidLoad {
[super viewDidLoad];

//读取文件

self.arr= [NSArray arrayWithContentsOfFile: [[NSBundle mainBundle]pathForResource:@"area.plist" ofType:nil]];
//设置标题
self.title=@"省";

//    NSLog(@"%@",self.arr);
//设置tableView 读取信息
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"reuseIdentifier"];

//

// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;

// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
//     self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}

#pragma mark - 每个分组的里面的个数

return self.arr.count;
}

#pragma mark - 设置显示信息

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

}

//    NSLog(@"%d",city.rows);

[self.navigationController pushViewController:city animated:YES];
}

#pragma mark - 行高

return 50;
}

}

*/

第二个页面 cityTableViewController.h

#import <UIKit/UIKit.h>
@interface cityTableViewController : UITableViewController
@property(nonatomic,assign)int rows;
@property(nonatomic,strong)NSArray *city;

@end

第二个页面 cityTableViewController.m

#import "cityTableViewController.h"

@interface cityTableViewController ()
@property(strong,nonatomic)NSMutableArray *array;
@end

@implementation cityTableViewController

- (void)viewDidLoad {
[super viewDidLoad];
self.array=[NSMutableArray array];
self.title=@"地级市";

//接收选择行的行数，及其数组
for (NSDictionary *city in self.city[self.rows][@"Cities"]) {
[self.array addObject:city[@"city"]];
}

//    NSLog(@"%@",self.city[self.rows][@"State"]);
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"reuseIdentifier"];

// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;

// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
//返回上一页
self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc]initWithTitle:@"back" style:2 target:self action:@selector(backpage)];
}

-(void)backpage{

[self.navigationController popToRootViewControllerAnimated:YES];
}

- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];

}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return self.array.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"reuseIdentifier" forIndexPath:indexPath];

cell.textLabel.text=self.array[indexPath.row];

return cell;
}

return 50;
}

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

}

指定根目录AppDelegate.h

#import <UIKit/UIKit.h>
#import "rootTableViewController.h"
@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@end

指定根目录AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

self.window.rootViewController=[[UINavigationController alloc]initWithRootViewController:[[rootTableViewController alloc]initWithStyle:UITableViewStylePlain]];
return YES;
}

这个页面的关键点就在于，在他选中的时候，要把选中的行数，和集合传到页面二中

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

cityTableViewController *city=[[cityTableViewController alloc]init];

//接收所在行的行数

city.rows=(int)indexPath.row;

//接收整个集合

city.city=self.arr;

// NSLog(@"%d",city.rows);

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

}

这个有点类似于页面跳转的属性传值，只要能传递要页面二中，后面的就好处理了

注：plist文件结构
