- （void）socket：（GCDAsyncSocket *）sock didReadData委托没有被调用？

Question

我在不使用Xmpp的情况下使用framework pods，但在发送数据包后委托didReadData未调用。

-(void)setupStream 
{
    xmppStream = [[XMPPStream alloc] init];

    [xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
    xmppStream.startTLSPolicy = XMPPStreamStartTLSPolicyRequired;

    [xmppStream setHostName:@"37.247.116.191"];

    [xmppStream setHostPort:5222];

}
