可可 - 如何使用ARC制作TCP套接字？

Question

你知道一些很好的教程，教你如何建立一个简单的TCP套接字连接到ip，并只是发送JSON到它？

我感到很沮丧，因为我找不到容易实现的东西（我还是新手）。

非常感谢你们！

我刚刚关注了raywenderlich教程：

并对流的启动做了一点调整：

- (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];
}
