如何从Objective c中的FCM通知中打开ViewController？

Question

我需要在单击通知时打开一个视图控制器。我可以推送到垂直的ViewController，但是我在api响应方面遇到了问题。

当我通过应用内或POSTMAN打开View Controller时，该api可以正常工作。

但是当我使用fcm willPresentNotification方法打开相同的视图时，它总是会使连接超时。

有什么建议吗？

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{

    //For notification Banner - when app in foreground

    completionHandler(UNNotificationPresentationOptionAlert);


    NSDictionary *userInfoDict = notification.request.content.userInfo;


     NSString *notificationFor = [userInfoDict valueForKey:@"gcm.notification.isWho"];


    NSString *doctorQuestionId = [userInfoDict valueForKey:@"gcm.notification.doctor_question_id"];
    NSLog(@"dcot ==%@",doctorQuestionId);


    UINavigationController *navController = (UINavigationController  *)self.window.rootViewController;
    UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
     QuizVC *vc = [mainStoryboard instantiateViewControllerWithIdentifier:@"QuizVC"];
    vc.fromNotification = @"Yes";
    vc.doctorQuestionID = doctorQuestionId;


    [navController pushViewController:vc animated:YES];

}
