我已经试着解决这个问题好几个星期了。苹果开发者论坛上没有回应。苹果开发者技术支持没有真正的帮助。考虑到这个问题在我的项目中发生的可能性很高，我不敢相信它没有得到任何人的解决。无论如何，这是我的GameKitManager类：
final class GameCenterManager : NSObject, GKLocalPlayerListener {
static let manager = GameCenterManager()
weak var delegate: GameCenterManagerDelegate?
var gameCenterViewController: UIViewController?
var match: GKMatch?
static var isAuthenticated: Bool {
return GKLocalPlayer.local.isAuthenticated
}
var matchmakerViewController: GKMatchmakerViewController?
var invite: GKInvite?
override init() {
super.init()
}
func authenticatePlayer() {
GKLocalPlayer.local.authenticateHandler = { gcAuthVC, error in
self.delegate?.didChangeAuthStatus(isAuthenticated: GKLocalPlayer.local.isAuthenticated)
if GKLocalPlayer.local.isAuthenticated {
GKLocalPlayer.local.register(self)
}
// If the User needs to sign to the Game Center
else if let vc = gcAuthVC {
self.delegate?.presentGameCenterAuth(viewController: vc)
}
else {
print(">>>>> Error authenticating the Player! (error?.localizedDescription ?? "none") <<<<<")
}
}
}
func presentMatchmaker() {
guard GKLocalPlayer.local.isAuthenticated else { return }
let request = GKMatchRequest()
request.minPlayers = 2
request.maxPlayers = 4
request.inviteMessage = "Would you like to play?"
matchmakerViewController = GKMatchmakerViewController(matchRequest: request)
matchmakerViewController!.matchmakerDelegate = self
delegate?.presentMatchmaking(viewController: matchmakerViewController)
}
func player(_ player: GKPlayer, didAccept invite: GKInvite) {
self.invite = invite
// Start match making 4 seconds after to let the invitation sliding menu to finish loading
let seconds = 4.0
DispatchQueue.main.asyncAfter(deadline: .now() + seconds) {
self.makeMatchmakerVC(from: invite)
}
}
func makeMatchmakerVC(from invite:GKInvite) {
// Accepting invitation from GKMatchmakerViewController (Friends are displayed)
if matchmakerViewController != nil {
matchmakerViewController!.dismiss(animated: true, completion: {
self.matchmakerViewController = GKMatchmakerViewController(invite: invite)
self.matchmakerViewController!.matchmakerDelegate = self
self.delegate?.presentMatchmaking(viewController: self.matchmakerViewController!)
})
}
// Accepting invitation when GKMatchmakerViewController is not yet presented
else {
guard let vc = GKMatchmakerViewController(invite: invite) else { return }
self.matchmakerViewController = vc
matchmakerViewController!.matchmakerDelegate = self
delegate?.presentMatchmaking(viewController: matchmakerViewController!)
}
}
}
extension GameCenterManager: GKMatchmakerViewControllerDelegate {
func matchmakerViewController(_ viewController: GKMatchmakerViewController, didFind match: GKMatch) {
print("-----matchmakerVC did find match-------")
viewController.dismiss(animated: true, completion: {
self.match = match
self.match!.delegate = self
self.delegate?.presentGame(match: self.match!)
})
}
func matchmakerViewControllerWasCancelled(_ viewController: GKMatchmakerViewController) {
viewController.dismiss(animated: true)
delegate?.matchmakingCancelled()
}
func matchmakerViewController(_ viewController: GKMatchmakerViewController,
didFailWithError error: Error)
{
viewController.dismiss(animated: true, completion: {
print("################# fail with error ##################n(error.localizedDescription)n")
self.matchmakerViewController!.matchmakerDelegate = nil
self.matchmakerViewController = nil
self.invite = nil
self.match = nil
})
}
}
这就是如何复制问题。
玩家启动应用程序。两者都会看到简介屏幕。
播放器1点击"；在GameCenter中玩"；。Matchmaker VC现在对玩家1开放。
玩家1将玩家2添加到游戏中，然后点击"邀请"one_answers"开始"按钮。
播放器2收到邀请(从顶部滑动消息)，并立即点击它以接受邀请(不要等待邀请来完成乐曲播放)。请注意，播放器2仍处于简介场景中。
玩家2收到连接错误，即使他/她接受了邀请，而玩家1被通知玩家2加入了游戏并进入游戏场景。
就代码流而言，播放器2调用方法"播放器(播放器：邀请：)"；根据邀请创建新的matterViewController并呈现；完成后，播放器2收到以下错误：
-----玩家--确实接受了邀请-------玩家2

#################失败，出现错误##############
操作无法完成。(ExtensionErrorDomain错误-5900。)
玩家2抛出方法"matherViewController(viewController:error:)"，但由于他/她已经接受了邀请，玩家1认为邀请已经被接受，并使用"self.delegate"继续游戏？。presentGame(match:self.match！)'.
这种情况并非每次都会发生，而是每2次或第3次当玩家2过早接受邀请时都会发生。
如果有人能帮忙的话，请提前感谢！
如果有人遇到同样的问题，以下方法会有帮助吗？
func player(_ player: GKPlayer, didAccept invite: GKInvite) {
if matchmakerViewController != nil {
matchmakerViewController!.dismiss(animated: false, completion: nil)
self.matchmakerViewController!.matchmakerDelegate = nil
self.matchmakerViewController = nil
}
let delayTime = DispatchTime.now() + .milliseconds(2000)
DispatchQueue.main.asyncAfter(deadline: delayTime) {
self.matchmakerViewController = GKMatchmakerViewController(invite: invite)
self.matchmakerViewController!.matchmakerDelegate = self
self.delegate?.presentMatchmaking(viewController: self.matchmakerViewController!)
}
}
Dispatch.asyncAfter正在给系统时间来进行完整的"；"清理"；的matterViewController。我现在正在测试它，但其他人的反馈将不胜感激。
编辑：经过更多的测试，这并不是解决方案；问题还在继续。然而，我注意到，当第二个玩家打开GKMatchmakerViewController的实例时，我没有问题。换句话说，如果我先打电话给presentMatchmaker()，然后接受邀请，它就会工作。因此，例如，当第二个玩家不在游戏中并收到游戏邀请时，就会出现问题。因此，我将代码更改为以下代码，到目前为止似乎有效：
public func player(_ player: GKPlayer, didAccept invite: GKInvite) {
if matchmakerViewController != nil {
matchmakerViewController!.dismiss(animated: false, completion: nil)
self.matchmakerViewController!.matchmakerDelegate = nil
self.matchmakerViewController = nil
}
// THIS HELPS AVOID CRASH.
presentMatchmaker()
let delayTime = DispatchTime.now() + .milliseconds(1000)
DispatchQueue.main.asyncAfter(deadline: delayTime) {
self.matchmakerViewController = GKMatchmakerViewController(invite: invite)
self.matchmakerViewController!.matchmakerDelegate = self
self.delegate?.presentMatchmaking(viewController: self.matchmakerViewController!)
}
}
不是一个非常优雅的解决方案。。。
