QuickBlox聊天未登录

我正在研究swift和quickblox，并且试图在用户之间进行聊天。用户身份验证和登录正在正常运行，只是由于某种原因聊天未登录。有问题的代码：

                QBRequest.createSessionWithExtendedParameters(parameters, successBlock: { (response : QBResponse! ,session : QBASession!) -> Void in

                var currentUser = QBUUser()
                currentUser.ID = session.userID
                currentUser.password = userPassword as String
                QBChat().addDelegate(self)
                QBChat().loginWithUser(currentUser)



                let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
                appDelegate.initiateLocationServicesUpdates()

                self.boxView.removeFromSuperview()

                self.performSegueWithIdentifier("alreadySignedInSegue", sender: self)


                }, errorBlock: { (response : QBResponse!) -> Void in
                    self.boxView.removeFromSuperview()
                    NSLog("error: %@", response.error);
                    self.view.userInteractionEnabled = true
                    var alert : UIAlertController = UIAlertController()
                    let action : UIAlertAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)
                    if let error = response.error.reasons{
                        if  response.error.reasons.description.rangeOfString("Unauthorized") != nil{
                            alert = UIAlertController(title: "Oops", message: "Wrong Username/Password Combination", preferredStyle: UIAlertControllerStyle.Alert)
                            alert.addAction(action)
                            self.presentViewController(alert, animated: true, completion: nil)
                        }
                    }
                    else{
                        alert = UIAlertController(title: "Oops", message: "Something Went Wrong, Its Our Fault!", preferredStyle: UIAlertControllerStyle.Alert)
                        alert.addAction(action)
                        self.presentViewController(alert, animated: true, completion: nil)
                    }
            })

成功块中找到的segue起作用，但是QBChat（）。isLoggedIn（）的值始终为false，如果我尝试通过

QBChat().sendMessage(message: QBChatMessage!)

功能我最终收到“必须登录才能聊天”消息。这一定是一个小问题，原因是我忽略了某些东西。

edit: 只是为了让您知道这是我第一次与quickblox合作，所以请准确了解我做错了什么
