iphone - 如何在基于 View 的应用程序中添加导航 Controller

Question

我想向基于 View 的应用程序添加导航 Controller 。我们如何以编程方式和使用 xib 文件来完成此操作..

Answer 1

如果您需要在 uiviewcontroller 中合并导航 Controller ，您需要按如下方式初始化它

UIViewController *yourViewController = ...

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:yourViewController];

[self presentModalViewController:navController animated:YES];

//you need to release the controller
[navController release];

如果你在UIApplicationDelegate方法中

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

你不能做一个presentModalViewController:navController动画...那么你需要将navController.view添加到窗口

    UIViewController *yourViewController = ...

    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:yourViewController];
    [self.window addSubview:navController.view];
    //don't do a release of navController because is not retained by addSubview
