can't receive message - Githubissues

我的部分iOS手机用户链接状态正常接受不到订阅消息，服务端用的emq，大部分用户都能正常接收。客户端链接代码如下： self.sessionManage = [[MQTTSessionManager alloc] init]; self.sessionManage.delegate = self; [self.sessionManage addObserver:self forKeyPath:@"state" options:NSKeyValueObservingOptionInitial | NSKeyValueObservingOptionNew context:nil]; self.sessionManage.subscriptions = [NSDictionary dictionaryWithObject:[NSNumber numberWithInt:MQTTQosLevelExactlyOnce] forKey:mqClientInfo[@"pushChannelId"]]; [self.sessionManage connectTo:kYXMQTTUrl port:kYXMQTTPORT tls:NO keepalive:60 clean:false auth:true user:@"admin" pass:@"public" will:NO willTopic:nil willMsg:nil willQos:MQTTQosLevelExactlyOnce willRetainFlag:false withClientId:mqClientInfo[@"pushClientId"] securityPolicy:nil certificates:nil protocolLevel:4 connectHandler:^(NSError *error) { }]; 从服务端观察，接收不了消息的用户，inflight window size 已经满了，并且该队列的消息在和客户端链接成功后也不会消耗。

请问这个问题最终怎么解决的？我们也有遇到

这个问题我们也没有解决，暂时出的临时方案出现收不到消息时候clean设置yes链接一下清空飞行队列然后断开，clean设置FALSE正常链接。目前已经在测试环境调飞行队列最大值为2很容易复现，准备更最新版的emq调试下。有进展了再沟通。

我们决定放弃这个库了，没人维护用emq 的CocoaMQTT 测试过这种情况正常，这是swift的只是要做桥接麻烦点
