接受邀请

Question

我正在使用GameKit作为新程序员来制作实时Game Center游戏，但是遇到了一些障碍。

我能够正确初始化本地播放器，显示配对控制器，并接收和接受邀请，但是，即使在我接受邀请之后， matchmakerViewController:didFindMatch也不会被调用，也不会返回任何匹配项。我极有可能没有正确接受邀请，但据我所拥有的苹果开发人员论坛称。如果有人可以查看这段代码并让我知道如何调用该方法，那就太好了！

let request = GKMatchRequest()

class SecondScreenViewController : UIViewController, UINavigationControllerDelegate, GKMatchmakerViewControllerDelegate, GKLocalPlayerListener {

    let button = UIButton()
    let softRed = UIColor(red: 1, green: 61 / 255, blue: 61 / 255, alpha: 1)
    let softblue = UIColor(red: 38 / 255, green: 149 / 255, blue: 1, alpha: 1)
    
    let TestMatchMaker = GKMatchmaker()
    let TestMatch = GKMatch()
    var TestViewController = GKMatchmakerViewController(matchRequest: request)
    
    var player = GKLocalPlayer.local

    override func viewDidLoad() {
        super.viewDidLoad()
        
        player.register(self)
        setupButton()
        SetupRequest()
        view.backgroundColor = softblue
        
       
    }

    func matchmakerViewControllerWasCancelled(_ viewController: GKMatchmakerViewController) {
       dismiss(animated: true, completion: nil)
        print("cancelled")
    }
    
    func matchmakerViewController(_ viewController: GKMatchmakerViewController, didFailWithError error: Error) {
        print(error.localizedDescription + "THIS IS AN ERROR FROM THE VIEWCONTROLLER")
    }
    
    func matchmakerViewController(_ viewController: GKMatchmakerViewController, didFind match: GKMatch) {
        print("Found Match Successfully")
        let TestMatch = match
        print(TestMatch)
    }
    
    
    func player(_ player: GKPlayer, didAccept invite: GKInvite) {
        print(invite)
        print("Aceppted Invite")
        
        TestViewController?.setHostedPlayer(player, didConnect: true)
        
        
        
    }
    
    func player(_ player: GKPlayer, didRequestMatchWithRecipients recipientPlayers: [GKPlayer]) {
        print("Requested Match")
    }
    
    func SetupRequest() {
        request.minPlayers = 2
        request.maxPlayers = 2
        request.inviteMessage = "test Invite"
    }

    
    func setupButton() {
         button.backgroundColor = UIColor.white
         button.setTitleColor(softblue, for: .normal)
         button.setTitle("MatchMake", for: .normal)
         button.addTarget(self, action: #selector(ButtonTapped), for: .touchUpInside)
         
         view.addSubview(button)
         setupButtonConstraints()
     }
     
     func setupButtonConstraints() {
         button.translatesAutoresizingMaskIntoConstraints = false
         button.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 30).isActive = true
         button.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -30).isActive = true
         button.heightAnchor.constraint(equalToConstant: 100).isActive = true
         button.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: 0).isActive = true
         
     }
     
     @objc func ButtonTapped() {
        
        present(TestViewController!, animated: true, completion: {
            self.TestViewController!.delegate = self})
        TestViewController?.matchmakerDelegate = self
        
        
     }
}

我看到的唯一可能是当您设置媒人代理时。这是我用来邀请玩家的代码，它工作正常：

func invitePlayers(){
    let request = GKMatchRequest()
    request.minPlayers = 2
    request.maxPlayers = 4
    request.defaultNumberOfPlayers = 2
    let vc = GKMatchmakerViewController(matchRequest: request)
    vc?.matchmakerDelegate = self
    self.present(vc!, animated: true)
}

请注意，在显示ViewController之前已设置matchmakerDelegate。
