ios - 将ViewController添加到堆栈并在需要时弹出

Question

我想在单击通知栏中的“通知”时导航到特定的 class ，然后在该特定的 class 中单击“后退”按钮，然后根据需要导航到上一个 class 。

谁能帮忙。

我已经添加了ViewController以这种方式堆叠

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];

    SplashViewController *splashViewCon = (SplashViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"SplashId"];
    AgreeViewController *agreeViewCon = (AgreeViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"agreeView"];
    ViewController *loginViewCon = (ViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"loginView"];
    LanguageViewController *languageViewCon = (LanguageViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"languageView"];
    LandingScreenViewController *landingViewCon = (LandingScreenViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"landingScreenId"];
    HomeScreenViewController *homeViewCon = (HomeScreenViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"homeScreen"];
    OrderConfirmationViewController *orderconfirmViewCon = (OrderConfirmationViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"orderConfirmationVC"];
    ThankYouViewController *thankViewCon = (ThankYouViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"ThankyouId"];
    UploadQueueScreenViewController *uploadViewCon = (UploadQueueScreenViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"uploadQueue"];
    NewOrderViewController *newOrderViewCon = (NewOrderViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"neworderView"];
    MessageViewController *msgViewCon = (MessageViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"MessageInboxscreen"];
    MessageDetailsViewController *msgdetailsViewCon = (MessageDetailsViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"msgDetailsView"];

    NSArray *stack = [NSArray arrayWithObjects:splashViewCon,agreeViewCon,loginViewCon,languageViewCon,landingViewCon,homeViewCon,orderconfirmViewCon,thankViewCon,uploadViewCon,newOrderViewCon,msgViewCon,msgdetailsViewCon, nil];
    navController.viewControllers = stack;

    UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

    if (notification)
    {
        MessageDetailsViewController *msgdetailsViewCon = (MessageDetailsViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"msgDetailsView"];
        self.window.rootViewController = msgdetailsViewCon;
    }
}

所以，我想弹出回到特定的viewController

据我所知，没有通用的类可用。尝试使用NSMutableArray，通过addObject添加，并通过objectAtIndex和removeObjectAtIndex获取第一个/最后一个。

您可能想要实现自己的代码以将其用作堆栈。
干杯:)
