Iphone 如何在基于视图的应用程序中创建NavigationController？

如何创建NavigationController以用于基于视图的应用程序？

将此代码
在delegate.h类中

      MyViewController *viewController;

在delegate.m类中

 - (void)applicationDidFinishLaunching:(UIApplication *)application {    

UINavigationController *nvcontrol =[[UINavigationController alloc] initWithRootViewController:viewController];

[window addSubview:nvcontrol.view];

[window makeKeyAndVisible];

}

此处“MyViewController”应替换为您的viewcontroller
祝您一切顺利。
请输入此代码

      MyViewController *viewController;

在delegate.m类中

 - (void)applicationDidFinishLaunching:(UIApplication *)application {    

UINavigationController *nvcontrol =[[UINavigationController alloc] initWithRootViewController:viewController];

[window addSubview:nvcontrol.view];

[window makeKeyAndVisible];

}

祝您一切顺利。
在delegate.h中

@class test24ViewController;

@interface test24AppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    test24ViewController *viewController;
    UINavigationController *nav;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet test24ViewController *viewController;
@property (nonatomic, retain) IBOutlet UINavigationController *nav;

在delegate.h中

@class test24ViewController;

@interface test24AppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    test24ViewController *viewController;
    UINavigationController *nav;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet test24ViewController *viewController;
@property (nonatomic, retain) IBOutlet UINavigationController *nav;
