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

问题描述

我使用 MCNearbyServiceBrowser 和 MCNearbyServiceAdvertiser 将两个对等点加入一个 MCSession.我可以使用 MCSession 的 sendData 方法在它们之间发送数据.一切似乎都按预期工作，直到我随机(而不是由于我控制的任何事件)通过会话的 MCSessionDelegate didChangeState 处理程序接收到 MCSessionStateNotConnected.此外，MCSession 的 connectedPeers 数组不再有我的同行.

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，我刚刚报告给 Apple.文档声称 didReceiveCertificate 回调是可选的，但事实并非如此.将此方法添加到您的 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);
 }

应该停止随机断开连接.

The random disconnects should cease.
