я используюSWRevealViewController в моем проекте, и я хочу открыть определенный контроллер, когда приложение получает уведомление. Я пробовал так много решений, но ничего не работает.

Как я могу показать определенный ViewController из моего AppDelegate?

(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

    UIApplicationState appState = UIApplicationStateActive;
    if ([application respondsToSelector:@selector(applicationState)]) {
        appState = application.applicationState;
    }
    application.applicationIconBadgeNumber = 0;
    if (appState != UIApplicationStateActive) {

        SWRevealViewController *navigationController = (SWRevealViewController *)self.window.rootViewController;
        UINavigationController *nav = (UINavigationController *)navigationController;
        UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
        PushNotificationsVC *controller = (PushNotificationsVC*)[mainStoryboard instantiateViewControllerWithIdentifier: @"PushNotificationsVC"];
        [nav pushViewController:controller animated:YES];

    } else {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Notification"
                                                            message:[NSString stringWithFormat:@"%@",[[userInfo objectForKey:@"aps"] valueForKey:@"alert"]]
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles:nil];
        [alertView show];
    }
}
