Question

我正在开发一款使用MPC的游戏。我得到了它的工作，但我发现连接（特别是超过2个对等体）经常失败。对等体开始连接（MCSessionState.Connecting），然后它们就没有（MCSessionState.NotConnected）。其他时候，它就像一个魅力。

这只是框架的问题，还是我可能做错了？

我跟着this tutorial。在我的实现中，其中一个播放器是浏览器，其余的是广告商。我提出的唯一解决方法是尝试再次连接，如果它获得.NotConnected标志，但有时它会尝试在成功之前重新连接3到4次（花费太长时间）。

以下是相关代码：

MPCManager（此类为MCSessionDelegate，MCNearbyServiceBrowserDelegate，MCNearbyServiceAdvertiserDelegate）

func advertiser(advertiser: MCNearbyServiceAdvertiser, didReceiveInvitationFromPeer peerID: MCPeerID, withContext context: NSData?, invitationHandler: (Bool, MCSession) -> Void) {
    self.invitationHandler = invitationHandler

    delegate?.invitationWasReceived(peerID.displayName)
}

// MARK: MCSessionDelegate method implementation


func session(session: MCSession, peer peerID: MCPeerID, didChangeState state: MCSessionState) {
    switch state{
    case MCSessionState.Connected:
        print("Connected to session: \(session)")
        connectedPeers.append(peerID)
        delegate?.connectedWithPeer(peerID)

    case MCSessionState.Connecting:
        print("Connecting to session: \(session)")

    default:
        delegate?.disconnectedFromPeer(peerID)
        print("Did not connect to session: \(session)")
    }
}

委托类：

func invitationWasReceived(fromPeer: String) {
    NSOperationQueue.mainQueue().addOperationWithBlock({ () -> Void in
        self.appDelegate.cManager!.invitationHandler(true, self.appDelegate.cManager!.session)
        self.connectingLabel.text = "Connecting"                
    })
}


func connectedWithPeer(peerID: MCPeerID) {
    NSOperationQueue.mainQueue().addOperationWithBlock({ () -> Void in
        self.connectingLabel.text = "Connected to \(peerID.displayName)"
        if self.appDelegate.cManager!.connectedPeers.count == self.appDelegate.cManager!.foundPeers.count {

        //game setup if all peers are connected
        //stop browsing and advertising
       }
    })
}

func disconnectedFromPeer(peerID: MCPeerID) {
    print("disconnected setup")
    NSOperationQueue.mainQueue().addOperationWithBlock({ () -> Void in
        self.connectingLabel.text = "Couldn't connect to \(peerID.displayName)\n\nRetrying"
        if self.isBrowser {
            self.appDelegate.cManager!.browser.invitePeer(peerID, toSession: self.appDelegate.cManager!.session, withContext: nil, timeout: 20)
        } 
    })


}

实施此委托方法

- (void)session:(MCSession *)session didReceiveCertificate:(NSArray *)certificate fromPeer:(MCPeerID *)peerID certificateHandler:(void (^)(BOOL accept))certificateHandler
{
     if (certificateHandler != nil)
     {
         certificateHandler(YES);
     }
}
