spinnerView не работает в appdelegate

Question

Здравствуйте, я использую appdeligate для определенного метода, например, входа в приложения и выхода из приложения. Вот у меня есть код , который в настоящее время делает работает большой, но проблема в том, когда запрос Войти отправить на сервер, то вид вертушка не работает

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
    // Override point for customization after application launch. 
    spinnerInitialization(); 
    email = NSUserDefaults.standardUserDefaults().stringForKey("email")\\Getting Email from local storage 
    password = NSUserDefaults.standardUserDefaults().stringForKey("password")\\\\Getting Password from local storage 
    if ((email == nil) && (password == nil)){ 

    } 
    else if ((email == "") && (password == "")) { 

    } 
    else { 
     loginRequest(email!, password: password!) 
    } 

    return true 

} 

Здесь Далее идет Логин Функция

func loginRequest(var email: String,password: String){ 

    let request = NSMutableURLRequest(URL: NSURL(string: "www.example.com/login")!) 
    request.HTTPMethod = "POST" 
    let postString = "email=\(email)&password=\(password)&token=\("ttttttt")" 

    dispatch_async(dispatch_get_main_queue()) { 
     self.startSpinner() 
    } 

    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding) 
    let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ 
     data, response, error in 
     if(error != nil){ 

      let nsError = error! as NSError 
      let dialog = UIAlertController(title: "Internal Server Error?", message: nsError.localizedDescription, preferredStyle: UIAlertControllerStyle.Alert); 

      let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default){(ACTION) in 

       print("Ok Button Action ") 
      } 

      dialog.addAction(okAction); 

      dispatch_async(dispatch_get_main_queue(), { 
       //Code that presents or dismisses a view controller here 
       self.window?.rootViewController?.presentViewController(dialog, animated: true, completion: nil) 
      }) 
     } 

     else{ 
     do { 
      let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) 

      let status = json["status"]as? Int 
      let message = json["message"]as? String 

      if(status == 0){ 


       let dialog = UIAlertController(title: "Login Unsuccessful?", message: message, preferredStyle: UIAlertControllerStyle.Alert); 

       let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default){(ACTION) in 

        print("Ok Button Action ") 
       } 

       dialog.addAction(okAction); 

       dispatch_async(dispatch_get_main_queue(), { 

        self.window?.rootViewController?.presentViewController(dialog, animated: true, completion: nil) 

       }) 


      } 
      else 
      { 
       let newModel = UserDetails() 
       let result = json["data"] 
       let userId = result!!["id"] as? String 
       let companyId = result!!["companyId"] as? String 
       let name = result!!["name"] as? String 
       let companyName = result!!["companyName"] as? String 
       email = (result!!["email"] as? String)! 
       let userType = result!!["userType"] as? String 

       NSUserDefaults.standardUserDefaults().setObject(email, forKey: "email") 
       NSUserDefaults.standardUserDefaults().setObject(userId, forKey: "userId") 
       NSUserDefaults.standardUserDefaults().setObject(companyId, forKey: "companyId") 
       NSUserDefaults.standardUserDefaults().setObject(name, forKey: "name") 
       NSUserDefaults.standardUserDefaults().setObject(companyName, forKey: "companyName") 
       NSUserDefaults.standardUserDefaults().setObject(userType, forKey: "userType") 
       NSUserDefaults.standardUserDefaults().setObject(password, forKey: "password") 
       NSUserDefaults.standardUserDefaults().setObject("afdg2015", forKey: "token") 

       newModel.userId = userId! 
       newModel.companyId = companyId! 
       newModel.userName = name! 
       newModel.companyName = companyName! 

       if userType == "0"{ 
        newModel.asEmployeer = true 
        NSUserDefaults.standardUserDefaults().setObject("true", forKey: "asEmployeer") 
        NSNotificationCenter.defaultCenter().postNotificationName("load", object: nil) 
       } 
       else { 
        newModel.asEmployeer = false 
        NSUserDefaults.standardUserDefaults().setObject("false", forKey: "asEmployeer") 
        NSNotificationCenter.defaultCenter().postNotificationName("load", object: nil) 
       } 

       self.userDetails.append(newModel) 

       dispatch_async(dispatch_get_main_queue()) { 

        let storyboard = UIStoryboard(name: "Main", bundle: nil) 
        var scheduleController = storyboard.instantiateViewControllerWithIdentifier("scheduleHome100") 
        if (newModel.asEmployeer == false){ 
        //EmployeeScheduleViewController 
         scheduleController = storyboard.instantiateViewControllerWithIdentifier("EmployeeScheduleViewController") 
        } 

        let drawerViewController = storyboard.instantiateViewControllerWithIdentifier("DrawerViewController") 

        let leftSideNav = UINavigationController(rootViewController: drawerViewController) 
        let centerNav = UINavigationController(rootViewController: scheduleController) 

        self.centerContainer = MMDrawerController(centerViewController: centerNav, leftDrawerViewController: leftSideNav) 
        self.centerContainer!.openDrawerGestureModeMask = MMOpenDrawerGestureMode.PanningCenterView; 
        self.centerContainer!.closeDrawerGestureModeMask = MMCloseDrawerGestureMode.PanningCenterView; 

        self.window!.rootViewController = self.centerContainer 
        self.window!.makeKeyAndVisible() 
       } 
      } 

     } catch { 
      print("error serializing JSON: \(error)") 
     } 
      dispatch_async(dispatch_get_main_queue(), { 
       self.stopSpinner() 
      }) 
     } 
    } 

    task.resume(); 
} 

Рядом с этим здесь блесны функционируют

func startSpinner(){ 
    print("In startSpinner Function") 
    view.addSubview(spinnerView) 
} 

func stopSpinner(){ 
    print("In stopSpinner Function") 
    let subViews = view.subviews 
    for subView in subViews{ 
     if subView.tag == 1000{ 
      subView.removeFromSuperview() 
     } 

    } 
} 

func spinnerInitialization(){ 
    print("In spinnerInitialization Function") 
    spinnerView = UIView(frame: CGRect(x:0, y:0,width: 250,height: 50)) 
    spinnerView.backgroundColor = UIColor.blackColor() 
    spinnerView.layer.cornerRadius = 10 
    let wait = UIActivityIndicatorView(frame: CGRect(x:0,y: 0,width: 50,height: 50)) 
    wait.color = UIColor.whiteColor() 
    wait.hidesWhenStopped = false 
    wait.startAnimating() 
    let text = UILabel(frame: CGRect(x:60,y:0,width:200,height: 50)) 
    text.textColor = UIColor.whiteColor() 
    text.text = "Please wait..." 
    spinnerView.addSubview(wait) 
    spinnerView.addSubview(text) 
    spinnerView.center = view.center 
    spinnerView.tag = 1000 
} 

UPDATE когда я посылаю запрос от ViewController вроде как

@IBAction func loginAction(sender: AnyObject) { 
    let email = textEmail.text 
    let password = textPassword.text 
    spinnerInitialization() 
    startSpinner() 
    let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate 
    appDelegate.loginRequest(email!, password: password!) 
} 

func spinnerInitialization(){ 
    spinnerView = UIView(frame: CGRect(x:0, y:0,width: 250,height: 50)) 
    spinnerView.backgroundColor = UIColor.blackColor() 
    spinnerView.layer.cornerRadius = 10 
    let wait = UIActivityIndicatorView(frame: CGRect(x:0,y: 0,width: 50,height: 50)) 
    wait.color = UIColor.whiteColor() 
    wait.hidesWhenStopped = false 
    wait.startAnimating() 
    let text = UILabel(frame: CGRect(x:60,y:0,width:200,height: 50)) 
    text.textColor = UIColor.whiteColor() 
    text.text = "Please wait..." 
    spinnerView.addSubview(wait) 
    spinnerView.addSubview(text) 
    spinnerView.center = self.view.center 
    spinnerView.tag = 1000 
} 

func startSpinner(){ 
    view.addSubview(spinnerView) 
} 

func stopSpinner(){ 
    let subViews = view.subviews 
    for subView in subViews{ 
     if subView.tag == 1000{ 
      subView.removeFromSuperview() 
     } 

    } 
} 

Затем счетчик показывает

Пожалуйста, помогите мне решить эту проблему Благодаря

Вы делаете dataTaskWithRequest который является Асинхронный обработать. Вы должны добавить обработчик завершения для того, чтобы ваша функция, чтобы ждать, пока процесс завершится примерно так:

func loginRequest(var email: String,password: String ,complete: (evalSuccess: Bool) ->()){ 

///Your code: 

    if(status == 0){ 


        let dialog = UIAlertController(title: "Login Unsuccessful?", message: message, preferredStyle: UIAlertControllerStyle.Alert); 

        let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default){(ACTION) in 

         print("Ok Button Action ") 
        } 

        dialog.addAction(okAction); 

        dispatch_async(dispatch_get_main_queue(), { 

         self.window?.rootViewController?.presentViewController(dialog, animated: true, completion: nil) 

        }) 


       } 
       else 
       { 
        complete(evalSuccess: True) 
        let newModel.. 
       ///your code 

      } 

И затем вызвать его в appDelegate как:

loginRequest(youremail, yourpassword){success in 
if success{ 
//Do something 
} 

}
