标题: iphone - 如何更改 Root View Controller

我想在 authenticationViewController 之后更改 rootViewController

-(IBAction)LoginButtonPushedid)sender {
    if ([(VerifyId)isEqual"C"]){
        CondidatsViewController *condidatsViewController = [[[CondidatsViewController alloc]initWithNibName"CondidatsViewController" bundle:nil]autorelease];
        UINavigationController *navController = self.navigationController;

        NSMutableArray *controllers = [[self.navigationController.viewControllers mutableCopy] autorelease];
        [controllers removeLastObject];
        navController.viewControllers = controllers;
        [navController pushViewController:condidatsViewController animated: YES];

    } else {
        RecruteursViewController *recruteursViewController = [[[RecruteursViewController alloc]initWithNibName"RecruteursViewController" bundle:nil]autorelease];
        UINavigationController *navController = self.navigationController;

        NSMutableArray *controllers = [[self.navigationController.viewControllers mutableCopy] autorelease];
        [controllers removeLastObject];
        navController.viewControllers = controllers;
        [navController pushViewController:recruteursViewController animated: YES];
    }
}

这段代码是当我按下登录按钮时，我希望 CondidatsViewController 或 RecruteursViewController 将成为 rootView

- (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    AcceuilViewController *viewController =[[[AcceuilViewController alloc]
                                             initWithNibName"AcceuilViewController" bundle:nil]autorelease];
    self.navController = [[[UINavigationController alloc]initWithRootViewController:viewController]
                         autorelease];
   self.window.rootViewController = self.navController;
    [self.window makeKeyAndVisible];
    return YES;
}

Best Answer-推荐答案

您可以尝试 UINavigationController 的以下方法，其中包含一组新的所需 View Controller ，例如

    [self.navigationController setViewControllers[newRootViewControllerInstance, secondVCInstanceIfRequired, thirdVC-and-so-on....] animated:NO];

它会做的伎俩;)
