从保存状态打开iOs应用程序

我的应用程序有两个主要功能：

预约功能

消息传递功能

在启动期间，应用程序下载数据的初始部分（将日历与服务器同步，从服务器获取新消息）。我使用一个启动屏幕来完成这个过程

当应用程序进入保存状态时，用户可以通过聊天室的推送消息打开应用程序

我已经超越了

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [[SKPaymentQueue defaultQueue] addTransactionObserver:[PurchaseHelper sharedInstance]];

    [Parse setApplicationId:kPLParseAppId clientKey:kPLParseClientId];
    [PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];

    [Crashlytics startWithAPIKey:@"mykey"];

    // social networks API        
    [PFFacebookUtils initializeFacebook];
    [[OkClient sharedInstance] initializeOdnoklassniki];
    [[VkClient sharedInstance] initializeVk];

    // load magical record support
    [MagicalRecord setupCoreDataStackWithStoreNamed:@"Model.sqlite"];

    // subscribe to notifications
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(userDidLogin) name:kPLUserDidLoginNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(userDidLogout) name:kPLUserDidLogoutNotification object:nil];

    // subscribe to pushes
    [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeSound];

    UIColor *greenColor = [UIColor colorWithRed:111 green:221 blue:215 andAlpha:255];
    if([[UINavigationBar appearance] respondsToSelector:@selector(barTintColor)]) {
        // iOS7
        [UINavigationBar appearance].barTintColor = greenColor;
    } else {
        // older
        [UINavigationBar appearance].tintColor = greenColor;
    }

    [[UINavigationBar appearance] setTitleTextAttributes:
     @{NSFontAttributeName : [UIFont fontWithName:@"Circe-Regular" size:16.],
       NSForegroundColorAttributeName: [UIColor blackColor]}];


    [[UIBarButtonItem appearance] setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"Circe-Regular" size:16.], NSForegroundColorAttributeName: [UIColor blackColor]} forState:UIControlStateNormal];

    // if app is started from push open chat
    if (launchOptions != nil) {
        NSDictionary *dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
        if (dictionary != nil) {
            ChatModel *chat = [self handlePushNotification:dictionary];
            [self launchChat:chat];
        }
    }

    // update purchase data if user is authenticated
    if ([[UserApiClient sharedInstance] isAuthenticated]) {
        [self updatePurchaseData];
    }

    // add styles
    [self addStyle];


    return YES;
}

而launchChat是：

- (void) launchChat:(ChatModel *) chat {
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    // reveal controller
    UIViewController *revealController = [storyboard instantiateViewControllerWithIdentifier:@"AuxController"];

    ChatViewController *chatController = [storyboard instantiateViewControllerWithIdentifier:@"chatVC"];
    chatController.chatModelId = chat.objectID;


    self.window.rootViewController = revealController;

    for (UIViewController *controller in [revealController childViewControllers]){
        if ([controller isKindOfClass:[UINavigationController class]]) {
            UINavigationController *navController = (UINavigationController *) controller;
            [navController pushViewController:chatController animated:YES];
            break;
        }
    }
}

但不幸的是，取而代之的是ChatViewController，我得到了常规的启动屏幕。我的错误在哪里？

我想您需要更换

窗口，而不仅仅是
rootViewController
。我不能说我已经用故事板做到了，所以这只是一个猜测

如果它不起作用，您需要删除故事板中的初始视图控制器指定，并在代码中为所有情况配置
rootViewController
。
在
didfishlaunchwithoptions
中的完整代码是什么？您所说的“替换窗口”是什么意思？通过创建一个新的
UIWindow
，将其设置为
rootViewController
，将其保存为
self.window
，然后在其上调用
makeKeyAndVisible
。
