我在Mac（Objective-C）应用程序中使用GCDAsyncSocket类时遇到问题。这是我得到的错误：

Apple Mach-O Linker (Id) Error

基本上我写了一个 NSData 对象：

[asyncSocket writeData:JSONRequestData withTimeout:-1 tag:1];

当运行时，调用委托

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

但由于某种原因，当写入到缓冲区时......它没有写出到服务器。

当我停止构建时，我猜套接字决定写入所有内容，并且服务器最终会看到它。

我该如何解决这个问题？没有办法刷新 CocoaAsyncSocket，因为它没有必要...我尝试添加行结尾，例如“/n”等，但这也没有任何作用。

我能够通过 IP 和端口连接到所需的套接字。

- (void)socket:(GCDAsyncSocket *)sender didConnectToHost:(NSString *)host port:(UInt16)port {\n\n    [sender startTLS:nil];\n\n    if(self.createTCPSocketHelperDelegate && @selector(returnConnectedTCPSocket:forNASWithMacAddress:))\n    {\n        [self.createTCPSocketHelperDelegate returnConnectedTCPSocket:sender forNASWithMacAddress:_macAddress];\n    }\n}\n

我正在发送 TLS 设置字典 nil，因为它使用默认设置。\n它给了我如下错误

Error Domain=kCFStreamErrorDomainSSL Code=-9806 "The operation couldn\xe2\x80\x99t be completed. (kCFStreamErrorDomainSSL error -9806.)" UserInfo=0x17d92420 {NSLocalizedRecoverySuggestion=Error code definition can be found in Apple\'s SecureTransport.h}\n

我不明白那里出了什么问题。请帮我提供一些连接到 SSL 服务器并使用 TCP/TLS 协议的示例代码。

如有帮助，将不胜感激。先感谢您。:)

我正在尝试将GCDAsyncSocket实现到 mac os x (Mojave 10.14.3) 应用程序以侦听来自 localhost:port 的数据。

问题是无论我选择哪个端口我总是会收到此错误：

Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"
UserInfo={NSLocalizedDescription=Operation not permitted, 
NSLocalizedFailureReason=Error in bind() function}

我已经尝试过这个，但没有成功。

这是我在AppDelegate.mm中的实现：

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    listenSocket = [[GCDAsyncSocket alloc] initWithDelegate:(id<GCDAsyncSocketDelegate>) self delegateQueue:dispatch_get_main_queue()];
    connectedSockets = [[NSMutableArray alloc] initWithCapacity:1];
    isRunning = NO;
    NSError *err = nil;
    if (![listenSocket connectToHost:@"localhost" onPort:12345 error:&err]){
        NSLog(@"I goofed: %@", err);
    }
}

-(void)getData{
    if(!isRunning)
    {
        int port = 12345;
        if(port < 0 || port > 65535)
        {
            port …
