为什么我的MCSession对等端会随机断开连接？ [英] Why does my MCSession peer disconnect randomly?

问题描述

我使用MCNearbyServiceBrowser和MCNearbyServiceAdvertiser将两个对等方连接到MCSession。我可以使用MCSession的sendData方法在它们之间发送数据。所有似乎都按预期工作，直到我随机（并且不是由于我控制的任何事件）通过会话的MCSessionDelegate didChangeState处理程序接收MCSessionStateNotConnected。此外，MCSession的connectedPeers数组不再拥有我的同伴。

Im using MCNearbyServiceBrowser and MCNearbyServiceAdvertiser to join two peers to a MCSession. I am able to send data between them using MCSession's sendData method. All seems to be working as expected until I randomly (and not due to any event I control) receive a MCSessionStateNotConnected via the session's MCSessionDelegate didChangeState handler. Additionally, the MCSession's connectedPeers array no longer has my peers.

两个问题：为什么？以及如何防止MCSession断开连接？

Two questions: Why? and How do i keep the MCSession from disconnecting?

推荐答案

这是一个错误，我刚刚向Apple报告。文档声称 didReceiveCertificate 回调是可选的，但事实并非如此。将此方法添加到 MCSessionDelegate ：

This is a bug, which I just reported to Apple. The docs claim the didReceiveCertificate callback is optional, but it's not. Add this method to your MCSessionDelegate:

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

随机断开连接应该停止。

The random disconnects should cease.
