iOS：当我尝试发送消息时，无法使用NSOutputStream连接将消息发送到套接字服务器

Question

I have used following code to connect to the server

- (void) initNetworkCommunication
{
  CFReadStreamRef readStream;
  CFWriteStreamRef writeStream;
  CFStreamCreatePairWithSocketToHost(NULL,(CFStringRef)URLBASE, 8080, &readStream, &writeStream);

  inputStream = (__bridge_transfer NSInputStream *)readStream;
  outputStream = (__bridge_transfer NSOutputStream *)writeStream;

  [inputStream setDelegate:self];
  [outputStream setDelegate:self];
  [inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
  [outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
  //    open input and output stream of socket to send and receive data
  [inputStream open];
  [outputStream open];
}

and following code to send message using output stream

-(IBAction)sendMessage{
   if (outputStream.hasSpaceAvailable) {
      [outputStream write:[data bytes] maxLength:[data length]];
   }
}

but when I try to send message the connection drops and gives connection reset by remote peer.

Answer 1

when I try to send message the connection drops and gives connection reset by remote peer.

The error text unequivocally states that the peer dropped the connection, so you have to look there for the reason rather than in the code above.
