iOS--頁面跳轉(UITableView)，ios--uitableview

iOS--頁面跳轉(UITableView)，ios--uitableview

本文只要實現運用（UITableView）表格實現頁面的傳值，同時運用了代理（委託）傳值。

目錄檔案清單如下:

AddressBookViewController.h

#import <UIKit/UIKit.h>#import "ContentViewController.h"@interface AddressBookViewController : UIViewController<UITableViewDelegate,UITableViewDataSource,postValueDelegate>@end

AppDelegate.h

#import <UIKit/UIKit.h>#import "AddressBookViewController.h"@interface AppDelegate : UIResponder <UIApplicationDelegate>@property (strong, nonatomic) UIWindow *window;@end

 

AppDelegate.m

#import "AppDelegate.h"@interface AppDelegate ()@end@implementation AppDelegate- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    AddressBookViewController *AddressBook=[[AddressBookViewController alloc] init];        UINavigationController *na=[[UINavigationController alloc] initWithRootViewController:AddressBook];    self.window.rootViewController=na;    return YES;}.........@end

注意：

1、在第一頁只需要點擊UITableView對應的值；

2、在第二頁需要按鍵盤上的 return 健才能傳值到第一頁。

運行結果:
