Cocoa-如何使用ARC制作TCP套接字

Question

你知道一些很好的教程吗，教你如何建立一个简单的TCP套接字连接到ip，并向其发送JSON？

我很沮丧，因为我找不到容易实现的东西（我还是个新手）。

谢谢大家！

我刚刚学习了raywenderlich教程：

并对流的启动进行了一点调整：

- (void) initNetworkCommunication {
    CFReadStreamRef readStream;
    CFWriteStreamRef writeStream;
    CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"xx.xxx.xxx.xxx", 1256, &readStream, &writeStream);
    inputStream = objc_unretainedObject(readStream);
    outputStream = objc_unretainedObject(writeStream);
    [inputStream setDelegate:self];
    [outputStream setDelegate:self];
    [inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [inputStream open];
    [outputStream open];
}
