我在xcode客户端使用c＃socket编程时遇到某种连接问题

问题描述

我在使用c sharp服务器连接xcode客户端时遇到了一些问题。我在虚拟机中运行mac并获得此输出

014-03-19 10：30：12.468 FYPSeconf [761：c07] Tcp客户端初始化

2014-03 -19 10：30：12.487 FYPSeconf [761：c07] TCP客户端 - 无法连接到主机

2014-03-19 10：30：12.487 FYPSeconf [761：c07]数据已发送登录,,, 192.168.1.1

2014-03-19 10：30：12.488 FYPSeconf [761：c07]收到的数据（null）

2014-03-19 10： 30：12.679 FYPSeconf [761：c07] TCP客户端 - 无法连接到主机



以下是我正在使用的代码。



- （无效）TcpClientInitialise

{

NSLog（@Tcp客户端初始化）;



CFReadStreamRef readStream;

CFWriteStreamRef writeStream;





CFStreamCreatePairWithSocketToHost（NULL， （CFStringRef）@localhost，9050，& readStream，& writeStream）;



InputStream =（__ bridge NSInputStream *）readStream;

OutputStream =（__ bridge NSOutputStream *）writeStream;



[InputStream setDelegate：self];

[OutputStream setDelegate：self];



[InputStream scheduleInRunLoop：[NSRunLoop currentRunLoop] forMode：NSDefaultRunLoopMode];

[OutputStream scheduleInRunLoop：[NSRunLoop currentRunLoop] forMode：NSDefaultRunLoopMode];



[InputStream打开];

[OutputStream打开];

}

i am facing some problems with connecting xcode client with c sharp server. i am running mac in a virtual machine and getting this output
014-03-19 10:30:12.468 FYPSeconf[761:c07] Tcp Client Initialise
2014-03-19 10:30:12.487 FYPSeconf[761:c07] TCP Client - Can't connect to the host
2014-03-19 10:30:12.487 FYPSeconf[761:c07] Data Sent LOGIN,,,192.168.1.1

2014-03-19 10:30:12.679 FYPSeconf[761:c07] TCP Client - Can't connect to the host

following is the code that i am using.

- (void)TcpClientInitialise
{
NSLog(@"Tcp Client Initialise");

CFReadStreamRef readStream;
CFWriteStreamRef writeStream;


CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"localhost", 9050, &readStream, &writeStream);

InputStream = (__bridge NSInputStream *)readStream;
OutputStream = (__bridge NSOutputStream *)writeStream;

[InputStream setDelegate:self];
[OutputStream setDelegate:self];

[InputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[OutputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];

[InputStream open];
[OutputStream open];
}

and for receiving stream

- (void)stream:(NSStream *)theStream handleEvent:(NSStreamEvent)StreamEvent
{

    switch (StreamEvent)
    {
        case NSStreamEventOpenCompleted:
            NSLog(@"TCP Client - Stream opened");
            break;

        case NSStreamEventHasBytesAvailable:
            if (theStream == InputStream)
            {
                uint8_t buffer[1024];
                int len;

                while ([InputStream hasBytesAvailable])
                {
                    len = [InputStream read:buffer maxLength:sizeof(buffer)];
                    if (len > 0)
                    {
                        NSString *output = [[NSString alloc] initWithBytes:buffer length:len encoding:NSASCIIStringEncoding];

                        if (nil != output)
                        {
                            NSLog(@"TCP Client - Server sent: %@", output);
                        }



                        //Send some data (large block where the write may not actually send all we request it to send)
                        int ActualOutputBytes = [OutputStream write:[OutputData bytes] maxLength:[OutputData length]];

                        //if (ActualOutputBytes >= ChunkToSendLength)
                        //{

            [theStream close];
            [theStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
            break;
