如何将navigationViewController添加到UIViewController

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

    loginViewController *vc1=[[loginViewController alloc]initWithNibName:@"login" bundle:[NSBundle mainBundle]];

    rootViewController* vc2 = [[[rootViewController alloc] init] autorelease];

    UINavigationController* navController = [[[UINavigationController alloc]

                                              initWithRootViewController:vc2] autorelease];
    NSArray* controllers = [NSArray arrayWithObjects:vc1,navController, nil];
    //loginViewController.viewControllers = controllers;



    [window addSubview:[self.loginController view]];
    // Override point for customization after application launch
    [window makeKeyAndVisible];
}

我被困在这里。需要一些帮助…

如果我理解正确，你应该使用

然后，您可以向self.navigationController发送推送/弹出消息，以管理navigationController堆栈的内容。

最简单的方法是在设置navController时更改init。此外，您还需要保留navController，可能作为应用程序委托的成员变量：

//in your header file:
....class definition
    UINavigationController    *_navigationController;
....

//in your implementation file:
_navigationController = [[UINavigationController alloc] initWithRootViewController: rootViewController];
//optional: if you want to start off 'one level in' to your navigation stack:
[_navigationController pushViewController: vc1 animated: NO];
[window addSubview _navigationController.view];

谢谢你，本，你的答案是完整的！

//in your header file:
....class definition
    UINavigationController    *_navigationController;
....

//in your implementation file:
_navigationController = [[UINavigationController alloc] initWithRootViewController: rootViewController];
//optional: if you want to start off 'one level in' to your navigation stack:
[_navigationController pushViewController: vc1 animated: NO];
[window addSubview _navigationController.view];
