使用Xcode在iOS上实现多重连接

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

在尝试连接时工作但几秒钟后,它再次使用MCSessionState == .notConnected调用.

尝试使用WiFi,BT和两者之间的所有组合……

刚刚添加：

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

没有多少帮助…仍然进入控制台(仅在iOS 10.2设备上,但是……)：
