如何在基于视图的应用程序中创建NavigationController？

Question

我应该如何创建一个在基于视图的应用程序中使用的NavigationController？

Answer 1

把这段代码

代表.h班

      MyViewController *viewController;

在委托.m班

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

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

[window addSubview:nvcontrol.view];

[window makeKeyAndVisible];

}

此处“MyViewController”应由viewcontroller替换。

所有最好的。

Answer 3

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.m

@synthesize nav;

#pragma mark -
#pragma mark Application lifecycle

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    nav=[[UINavigationController alloc]init];
        [nav pushViewController:viewController animated:YES];
    // Override point for customization after application launch.


    [self.window addSubview:nav.view];

    [self.window makeKeyAndVisible];

    return YES;
}
