ios - 使用 Xcode 在 iOS 上实现多点连接

Question

广告和浏览的设备。 尝试建立连接时出现问题。

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

尝试连接时正常工作，但几秒钟后，它再次调用 MCSessionState == .notConnected 。

尝试了 WiFi、BT 以及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>

没有太大帮助...仍然进入控制台(不过只是在 iOS 10.2 设备上...):

(广告商是应用程序的名称) 使用带有 10.2 的 iPhone 6S 和带有 9.2 的 iPhone 6。 从 Xcode 8.2.1 (Swift3) 使用 macOS Sierra v10.12.2 在 Macbook Pro 上运行代码。

Answer 1

您是否为广告客户和浏览器保留了对 MCSession 对象的引用？如果正在使用的 MCSession 对象被释放，就会出现那些 BINDING_REQUEST 失败消息。
