帶導覽列的最簡單多視圖，帶導覽列簡單視圖

首先你要建立2個繼承自UIViewController的類 。

命名為FirstViewController和secondViewController。

首先在AppDelegate.h檔案中引入標頭檔

 

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

 

 然後在AppDelegate.m中寫下

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

 

這個方法裡面實現 ， 放心它就在第一個，你不用擔心找不到。 * 。*

 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {        FirstViewController *firstVc=[[FirstViewController alloc] init];        UINavigationController *navc=[[UINavigationController alloc] initWithRootViewController:firstVc];    self.window.rootViewController=navc;        return YES;}

 

在FirstViewController.h檔案中引入標頭檔

#import <UIKit/UIKit.h>#import "SecondViewController.h"@interface FirstViewController : UIViewController@end

 

然後在FirstViewController.m檔案中寫下

 

#import "FirstViewController.h"@interface FirstViewController ()@end@implementation FirstViewController- (void)viewDidLoad {    [super viewDidLoad];        self.view.backgroundColor=[UIColor redColor];        self.title=@"First";        UIBarButtonItem *nextItem=[[UIBarButtonItem alloc] initWithTitle:@"next" style:UIBarButtonItemStylePlain target:self action:@selector(nextPage)];        self.navigationItem.rightBarButtonItem=nextItem;        }-(void)nextPage{        SecondViewController *secondVc=[[SecondViewController alloc] init];    [self.navigationController pushViewController:secondVc animated:YES];     }- (void)didReceiveMemoryWarning {    [super didReceiveMemoryWarning];

 最後就在SecondViewController.m檔案中

 

#import "SecondViewController.h"@interface SecondViewController ()@end@implementation SecondViewController- (void)viewDidLoad {    [super viewDidLoad];    self.view.backgroundColor=[UIColor greenColor];//    隱藏返回按鈕    self.navigationItem.hidesBackButton=YES;    // Do any additional setup after loading the view.        self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc] initWithTitle:@"back" style:2 target:self action:@selector(backPage)];    }-(void)backPage{    [self.navigationController popToRootViewControllerAnimated:YES];}- (void)didReceiveMemoryWarning {    [super didReceiveMemoryWarning];

 

  效果如下
