如何在iOS Swift2中使用解析获取Google+登录的会话令牌

我在一个应用程序的工作中使用谷歌加登录
它工作正常，但我想与解析集成还
我指例如

func finishedWithAuth(auth: GTMOAuth2Authentication!, error: NSError!) {
    let token = auth.accessToken            
    PFUser.becomeInBackground(token, block: { (user : PFUser?, error : NSError?) -> Void in
       if error != nil {
           print("Error in become user : \(error)")
       } else {
           print("user : \(user)")
       }
    })
}

但这给了我类似的错误

Error in become user : Optional(Error Domain=Parse Code=209 "invalid session token" UserInfo={code=209, temporary=0, error=invalid session token, NSLocalizedDescription=invalid session token})

我也尝试过这个示例，在parse.com上的ios中使用google plus登录google，
但它在目标c中，尝试转换为swift2但也给出错误

请给我正确的解决方案

最终解决的问题
将答案转换为快速代码，并且工作正常

func finishedWithAuth(auth: GTMOAuth2Authentication!, error: NSError!) {
     if error == nil && auth.expirationDate.compare(NSDate(timeIntervalSinceNow: 0)) == NSComparisonResult.OrderedDescending {

         let user = GPPSignIn.sharedInstance().googlePlusUser
         let userName = user.name.JSONValueForKey("givenName") as! String
         let userEmail = GPPSignIn.sharedInstance().userEmail

         let pfUser = PFUser()
         pfUser.username = userName
         pfUser.email = userEmail

         let userPassword = "\(userName)@123"
         pfUser.password = userPassword

         pfUser.signUpInBackgroundWithBlock({ (success, error : NSError?) -> Void in

          if error == nil {

             let plusService = GTLServicePlus()
             plusService.retryEnabled = true
             plusService.authorizer = GPPSignIn.sharedInstance().authentication

             let query : GTLQueryPlus! = GTLQueryPlus.queryForPeopleGetWithUserId("me") as! GTLQueryPlus

             plusService.executeQuery(query, completionHandler: { (ticket, person, error) -> Void in
                 if error != nil {
                    print("Error in execute query : \(error!)")
                 } else {
                    let aPerson : GTLPlusPerson! = person as! GTLPlusPerson
                    let imgUrl = aPerson.image.url

                    if let imgData = NSData(contentsOfURL: NSURL(string: imgUrl)!) {
                        self.userProfilePic.image = UIImage(data: imgData)
                    }

                    let currentUser = PFUser.currentUser()
                    currentUser?.username = aPerson.displayName
                    currentUser?.saveInBackground()
                 }
              })

          } else {

              print("Error in signup : \(error!.localizedDescription)")

              PFUser.logInWithUsernameInBackground(self.userName, password: userPassword, block: { (user : PFUser?, error : NSError?) -> Void in
                if error == nil {
                            print("Login Sccessfully")
                } else {
                            print("Error in login : \(error!.localizedDescription)")
                       }
              })
          }
       })
        } else {
            print("Error in authentication : \(error.localizedDescription)")
        }
    }

希望对某人有所帮助！！！
