iOS上的多重連接與Xcode

這兩種設備都可以廣告和瀏覽。嘗試建立連接時發生問題。iOS上的多重連接與Xcode

func session(_ session: MCSession, peer peerID: MCPeerID, didChange state: MCSessionState) {}

是否嘗試連接，但幾秒鐘後，它被再次MCSessionState == .notConnected致電時工作。

具備WiFi，藍牙，以及兩者之間的每一個組合都嘗試...

只是說：

<key>NSAppTransportSecurity</key> 
<dict> 
    <key>NSAllowsArbitraryLoads</key> 
    <true/> 
    <key>NSTemporaryExceptionRequiresForwardSecrecy</key> 
    <false/> 
</dict>

沒幫多少...仍然在控制檯得到（只在iOS 10.2裝置，雖然...）：

（廣告商是應用程序的名稱）使用iPhone 6S 10.2 & iPhone 6 9.2。使用maccode Sierra v10.12.2從Xcode 8.2.1（Swift3）在Macbook Pro上運行代碼。

如果兩個設備在建立連接後繼續進行廣告和瀏覽，則當它們重新發現對方時它們可能會斷開連接。建立連接後，請通過以下方式關閉瀏覽：

MCNearbyServiceBrowser.stopBrowsingForPeers()

如果設備繼續播發，其他設備仍然可以連接到它們。

您是否保留對廣告客戶和瀏覽器的MCSession對象的引用？那些BINDING_REQUEST失敗的消息確實發生，如果正在使用的MCSession對象被取消分配。

我有同樣的問題，我找到了解決方案。它仍然顯示一些錯誤，但它適用於我。

嘗試初始化MCSession如下：

let mcSession = MCSession(peer: self.mcPeerId, securityIdentity: nil, encryptionPreference: .none)

然後實現MCSession的證書處理程序委託方法如下：

func session(_ session: MCSession, didReceiveCertificate certificate: [Any]?, fromPeer peerID: MCPeerID, certificateHandler: @escaping (Bool) -> Void) { 
    certificateHandler(true) 
}
