Afficher l'alerte dans la vue actuelle, ainsi que Rediriger vers une autre vue

Question

Je souhaite afficher une alerte pour vérifier la nouvelle version de mon application depuis l'API. Et à partir de ce point de vue, si les données userDefault sont stockées, je veux rediriger vers une autre vue. Mon code de redirection fonctionne parfaitement, mais lorsque j'ajoute un code d'alerte, la redirection ne fonctionne pas. Je pense que l'alerte est présente dans "moi-même" et cette fois-ci, j'essaie aussi de rediriger à partir de ce point de vue, ce qui peut créer un problème. Voici mon code ..

override func viewWillAppear(_ animated: Bool) { 
      super.viewWillAppear(animated) 
      updateUserData() //base on userDefault redirection 
     } 
    override func viewDidAppear(_ animated: Bool) { 
      super.viewDidAppear(animated) 
      checkNewVersion() //Alert function for API calling 
     } 

func checkNewVersion() -> Void { 

    //TODO: For check App new version 
     WebRequester.shared.getAppNewVersion { (result, error) in 
     if result != nil { 
      if result?.value(forKey: "status") as! Bool { 
       let strVer = (result?.object(forKey: "data") as! NSDictionary).object(forKey: "platform_version") as! String 
       if UserData.getAppVersion() < strVer { 
        let alert = UIAlertController(title: "Alert", message: "New version of App available", preferredStyle: .alert) 
        let ok = UIAlertAction(title: "Ok", style: .default, handler: { (action) in 
        }) 
        let AppStore = UIAlertAction(title: "App Store", style: .default, handler: { (action) in 
         if let url = URL(string: "itms-apps://itunes.apple.com/app/id1024941703"), 
          UIApplication.shared.canOpenURL(url){ 
          UIApplication.shared.openURL(url) 
         } 
        }) 
        alert.addAction(ok) 
        alert.addAction(AppStore) 
        self.present(alert, animated: true, completion: nil) 
//     OperationQueue().addOperation { 
//      // Put queue to the main thread which will update the UI 
//      OperationQueue.main.addOperation({ 
//       self.present(alert, animated: true, completion: nil) 
//      }) 
//     } 

       } 
      } 
      else { 
       if (result?.object(forKey: "data") as! NSArray).object(at: 0) as? String ?? "" == "Unauthorised access." { 
        Model.shared.deleteAllCoreDataRecord(entity: "CartItem") 
        UIApplication.topViewController()?.navigationController?.popToRootViewController(animated: true) 
       } 
       let msg = result?.value(forKey: "data") as! [String] 
       Model.shared.showAlert(title: "Error", msg: msg[0], controller: self) 
      } 
     } 
     else { 
      Model.shared.showAlert(title: "Error", msg: error?.localizedDescription ?? "Something went wrong at add new address", controller: self) 
     } 
    } 
} 

func updateUserData() -> Void { 
    if UserData.getAppVersion() == "1.0" { 

     if UserData.getUserData() != nil { 

      //TODO: check for user Updated data 
      let params = ["mobile":UserData.getUserMobile()] as [String : Any] 
      let propic = UIImage(named: "temp") 
      weak var objWeek = self 

      Model.shared.showActivity(WithTouchEnable: false,controller: self) 
      WebRequester.shared.customerSignup(params: params as NSDictionary, proImg: propic!){ (result,error) -> Void in 
       Model.shared.HideActivity(controller: self) 
       if (error == nil) { 
        print("login result:",result ?? "") 
        //handle response of sign up 
        let statusstr = result?["status"] as! Bool 
        if (statusstr == false) { 
         //This condition for pepsi welcome offer is expire or not 
         let user = result!["user_info"] as! NSDictionary 
         self.storeUserData(user: user) 

         if UserData.getUserMobileNumVerify() == "No" { 
          let storyboard = UIStoryboard(name: "Main", bundle: nil) 
          let registerScreen = storyboard.instantiateViewController(withIdentifier: "UserRegisterPhoneVC") as! UserRegisterPhoneVC 

          objWeek?.navigationController?.pushViewController(registerScreen, animated: true) 
         } 
         else { 
          if UserData.getPepsiOfferRedim() == "1" || UserData.getPepsiOfferRedim() == "2" { 
           let storyboard = UIStoryboard(name: "Main", bundle: nil) 
           let offerScreen = storyboard.instantiateViewController(withIdentifier: "OfferViewController") as! OfferViewController 
           objWeek?.navigationController?.pushViewController(offerScreen, animated: true) 
          } 
          else { 
           let storyboard = UIStoryboard(name: "Main", bundle: nil) 
           let promoScreen = storyboard.instantiateViewController(withIdentifier: "PromotionViewController") as! PromotionViewController 
           objWeek?.navigationController?.pushViewController(promoScreen, animated: true) 
          } 
         } 
        } 
       } 
      } 
      else { 
       Model.shared.showAlert(title: "Error", msg: (error?.localizedDescription)!, controller: self) 
      } 
     } 

    } 

} 
}

Pour ce faire, vous devez cliquer sur le bouton OK alerte alors seulement il naviguera automatiquement un autre contrôleur, sans que cela impossible.

Voici le code:

aide Alerte bloc de contrôleur pour ce faire, vous:

//show an alert and navigate to previous controller 
      let alertController: UIAlertController = UIAlertController(title: "Password updatd", message: "your alert message", preferredStyle: .alert) 

      let okAction: UIAlertAction = UIAlertAction(title: "OK", style: .default) { action -> Void in 

      //Redirect to new viewcontroler 
      let newVC = self.storyboard.instantiateViewcontroller(identifier: "newvc") as? NewVC 
      self.navigationController?.pushViewController(newVC,animated: true) 
      } 

      alertController.addAction(okAction) 
      self.present(alertController, animated: true, completion: nil)
