CocoaAsyncSocket的读写代理不会触发和代码组织

Question

我正在尝试使用cocoaasyncsocket库附带的echo服务器示例的修改版本执行以下操作:

1)打开与作为服务器的python脚本的连接
2)发送数据//工作,但委托不激活
3)接收数据//委托不激活
4)断开//不断开,显然还在我的帖子里

目前,我在didFinishLaunchingWithOptions委托中打开一个连接,然后尝试在didConnectToHost委托中发送数据.然后,我尝试读取从客户端返回的数据,然后断开连接.

我能够打开一个连接并发送数据(服务器验证为收到),但didWriteDataWithTag委托永远不会触发.但是,服务器接收数据.然后服务器会激活一些数据,但didReadData也不会触发.

除了读/写代理没有触发的事实,似乎我组织我的代码的方式不对,但我不确定这在事件驱动的系统中看起来如何与运行循环相反(我'在事件驱动的东西+网络新手.如果我的一系列行动的各自的完成是由他们的代表触发的,那么代表们是否应该分享某种消息 - 即我们收到了"xxx"消息,请回写"yyy"？我更喜欢有一个功能来管理所有这些.这样做有规范的方法吗？

IPhoneConnectTestAppDelegate.m(片段)

- (void)localConnect {
    NSError *error = nil;
    if (![asyncSocket connectToHost:@"localhost" onPort:5000 error:&error]) {
        DDLogError(@"Error connecting: %@", error);
    }
}

- (void)disconnect {
    [asyncSocket setDelegate:nil];
    [asyncSocket disconnect];
    [asyncSocket release];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Setup our socket (GCDAsyncSocket).
    dispatch_queue_t mainQueue = dispatch_get_main_queue();
    asyncSocket = [[GCDAsyncSocket alloc] initWithDelegate:self delegateQueue:mainQueue];

    [self localConnect];

    // Add the view controller's view to the window and display.
    [window addSubview:viewController.view];
    [window makeKeyAndVisible];
}


- (void)onSocket:(GCDAsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag {
    NSString *output = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
    NSLog(@"didReadData: %@", output);

}

- (void)onSocket:(GCDAsyncSocket *)sock didWriteDataWithTag:(long)tag {
    NSLog(@"didWriteDataWithTag");
}

- (void)socket:(GCDAsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port {
    NSLog(@"socket:%p didConnectToHost:%@ port:%hu", sock, host, port);
    if(port == 5000)
    {
        NSString *msg = @"q";
        NSData *dataOut = [msg dataUsingEncoding:NSASCIIStringEncoding];
        [asyncSocket writeData:dataOut withTimeout:-1 tag:0];
        [asyncSocket readDataWithTimeout:-1 tag:0];
        [self disconnect];
    }
}

tcpserver.py

# TCP server example
import socket, time
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(("", 5000))
server_socket.listen(5)

print "TCPServer Waiting for client on port 5000"

while 1:
    client_socket, address = server_socket.accept()
    print "I got a connection from ", address
    while 1:
        data = client_socket.recv(512)
        print "Data from client",data

        time.sleep(2)
        data = "xxx"
        print "Sending data to client",data
        client_socket.send (data)
        break;

我知道这是一个已经被接受的答案的旧问题,但为了澄清那些发现这个线程寻找某事的人,委托方法没有被调用的原因是因为GCDAsynchSocket以socket:而不是onsocket:ie 开头:

- (void)onSocket:(AsyncSocket *)sock didWriteDataWithTag:(long)tag

变为:

- (void) socket:(GCDAsyncSocket *)sock didWriteDataWithTag:(long)tag
