Question

我正在开发一款非常简单的游戏来测试游戏中心的所有功能，并且更习惯Apple的GameKit以及所有这些功能。这个非常简单的游戏给了我很多问题，而且我已经慢慢地，但肯定地经历了。我遇到了一个新问题，我希望有人可以帮助我到目前为止，我可以做到以下几点：
- 连接到游戏中心＆amp;验证播放器
-Scoreboards＆amp;排行榜＆amp;提交分数
- 开始匹配过程（但不开始匹配）无论如何，这是我的“开始比赛”的代码。这是在比赛请求结束后，找到了2名球员：

func matchmakerViewController(_ viewController: GKMatchmakerViewController, didFind match: GKMatch) {
        print("Match found")
        if match.expectedPlayerCount == 0 {
            viewController.dismiss(animated: true, completion: {self.goToGame(match: match)})
        }

func goToGame(match: GKMatch) {
        let gameScreenVC = self.storyboard?.instantiateViewController(withIdentifier: "mainGame") as! ViewController
        gameScreenVC.providesPresentationContextTransitionStyle = true
        gameScreenVC.definesPresentationContext = true
        gameScreenVC.modalPresentationStyle = UIModalPresentationStyle.fullScreen
        gameScreenVC.modalTransitionStyle = UIModalTransitionStyle.crossDissolve
        gameScreenVC.match = match
        self.present(gameScreenVC, animated: true, completion: nil)
    }

现在，在那里调用的ViewController的代码有以下启动代码：

override func viewDidLoad() {
        super.viewDidLoad()
        yourTurnLabel.isHidden = true
        // Do any additional setup after loading the view, typically from a nib.
        matchStart()
    }

    func matchStart() {
        let localPlayerID = GKLocalPlayer.localPlayer().playerID
        let initialTurn = "initRand,\(localPlayerID ?? "ERROR: NO ID"),\(aTaps),0,0"
        let turnData = initialTurn.data(using: .utf8)
        print("Sending String: \(initialTurn)")
        sendData(turnLog: turnData!)
    }
func sendData(turnLog: Data) {
            do {
                try match?.sendData(toAllPlayers: turnLog, with: GKMatchSendDataMode.reliable)
                print("DATA SENT!")
            } catch {
            print("ERROR: \(error.localizedDescription)")
            }
    }

来自MatchMakingDelegate的以下扩展名：

extension ViewController: GKMatchDelegate {

    // The match received data sent from the player.
    @available(iOS 8.0, *)
    public func match(_ match: GKMatch, didReceive data: Data, fromRemotePlayer player: GKPlayer) {
        print ("RECEIVED DATA 8.0")
        print ("Received \(data) from \(player)")
        receiveData(turnLog: data)
    }

    @available(iOS 9.0, *)
    public func match(_ match: GKMatch, didReceive data: Data, forRecipient recipient: GKPlayer, fromRemotePlayer player: GKPlayer) {
        print("RECEIVED DATA 9.0")
        print ("Received \(data) for \(recipient) from \(player)")
    }

    // The player state changed (eg. connected or disconnected)
    @available(iOS 4.1, *)
    public func match(_ match: GKMatch, player: GKPlayer, didChange state: GKPlayerConnectionState) {
        print("CHANGED STATE")
    }


    // The match was unable to be established with any players due to an error.
    @available(iOS 4.1, *)
    public func match(_ match: GKMatch, didFailWithError error: Error?) {
        print("FAILED")
    }


    // This method is called when the match is interrupted; if it returns YES, a new invite will be sent to attempt reconnection. This is supported only for 1v1 games
    @available(iOS 8.0, *)
    public func match(_ match: GKMatch, shouldReinviteDisconnectedPlayer player: GKPlayer) -> Bool {
        return true
    }

}

现在，到目前为止，它似乎运行良好，直到我开始游戏，我在x-Code控制台中得到以下输出，我从未看到“receiveData”触发器

我希望你能帮我弄清楚code2是什么以及如何阻止它。谢谢！

您永远不会设置匹配委托。
