游戏中心比赛总是无效

Question

我正在尝试学习如何构建基于游戏中心的应用程序。这是一款非常简单的回合制游戏，基本上只是记录您按下的按钮并将其发送给其他玩家。由于 Apple 的文档尚未针对 Swift 更新，因此我很难实现所有游戏中心功能。我一直在猜测所有事情并阅读 Objective-C 个示例并希望得到最好的结果（不知何故我设法让一些事情继续进行，尽管我不确定它们是否正确）无论如何，我同时为我的模拟器和运行我的 phone 和模拟器上的应用程序创建了一个新的 iCloud 帐户，试图让它们在游戏中匹配。但是我总是收到 "match request is invalid" 错误：

编辑我已经在 iTunesConnect 中注册了该应用程序，我已经实现了排行榜并对其进行了测试并且它们有效（所以我假设 iTunesConnect 正常工作和设置）

@IBAction func startTapped(_ sender: Any) {
    let request = GKMatchRequest()
    request.maxPlayers = 2
    request.minPlayers = 1

    let mmvc = GKMatchmakerViewController(matchRequest: request)
    mmvc?.matchmakerDelegate = self
    present(mmvc!, animated: true, completion: nil)
}

extension HomeVC: GKGameCenterControllerDelegate
{

    func authenticatePlayer()
    {
        //CALLED ON VIEWDIDAPPEAR
        let localPlayer = GKLocalPlayer.localPlayer()

        localPlayer.authenticateHandler = {
            (view, error) in
            if view != nil
            {
                self.present(view!, animated: true, completion: nil)
            } else {
                print("AUTHENTICATED!")
                print(GKLocalPlayer.localPlayer().isAuthenticated)
            }
        }
    }
func gameCenterViewControllerDidFinish(_ gameCenterViewController: GKGameCenterViewController) {
        gameCenterViewController.dismiss(animated: true, completion: nil)
    }
}

这是配对代码。请注意，我可以让 Game Center 屏幕出现并告诉我 "how many players" 它缺少一个玩家并提供邀请朋友的选择等等

extension HomeVC: GKMatchmakerViewControllerDelegate {
    func matchmakerViewControllerWasCancelled(_ viewController: GKMatchmakerViewController) {
       print("match was cancelled")
        viewController.dismiss(animated: true, completion: nil)
    }

    func matchmakerViewController(_ viewController: GKMatchmakerViewController, didFailWithError error: Error) {
        print("didFailwithError: \(error.localizedDescription)")
    }

    func matchmakerViewController(_ viewController: GKMatchmakerViewController, didFind match: GKMatch) {

        print("Match found, ID: \(match.description)")
        let gameScreenVC = self.storyboard?.instantiateViewController(withIdentifier: "mainGame") as! ViewController
        gameScreenVC.providesPresentationContextTransitionStyle = true
        gameScreenVC.definesPresentationContext = true
        gameScreenVC.modalPresentationStyle = UIModalPresentationStyle.fullScreen
        gameScreenVC.modalTransitionStyle = UIModalTransitionStyle.crossDissolve
        match.delegate = gameScreenVC

        self.present(gameScreenVC, animated: true, completion: nil)

    }
}

如果有人遇到这个问题，我通过用相同的数量替换 "minelayers and max-layers" 来修复它，所以代码现在看起来像这样：

@IBAction func startTapped(_ sender: Any) {
    let request = GKMatchRequest()
    request.maxPlayers = 2 //min and max should be the same
    request.minPlayers = 2 //apparently they need to be the same

    let mmvc = GKMatchmakerViewController(matchRequest: request)
    mmvc?.matchmakerDelegate = self
    present(mmvc!, animated: true, completion: nil)
}

显然 Game Center 不喜欢 min.player 计数为 1，它无效。但这就是我停止给我无效匹配请求警告的方式
