Objective C NSStream连接总是被拒绝

我想在可可和可可触摸中设置一些NSInput/Output流。我试图通过Wifi在我的Mac和iPod之间建立连接。不管怎样，虽然我总是得到连接拒绝错误。我有每个设备的地址硬编码（因为它只是一个测试）。我基本上遵循苹果的文档无济于事。我一直坚持这几天。任何帮助将不胜感激！Objective C NSStream连接总是被拒绝

Mac代码。

    CFStreamCreatePairWithSocketToHost(NULL, (__bridge CFStringRef)([theHost address]), 80, &tempRead, &tempWrite); 

    myInput = (__bridge NSInputStream *)(tempRead);

我使用该链接的代码https://gist.github.com/thefifthcircuit/446256。我可以建议你看看这个 – meth 2013-03-17 01:28:13

该代码适合你，我认为？我以前看过那个页面，但它看起来和我的完全一样，所以我没有多想。我会仔细看看它。顺便说一下，你的地址是什么？我使用的东西像10.0.1.5（本地连接）这是正确的吗？ – Sequence 2013-03-17 01:38:59

嗯，我没有太多有关地址的信息，但因为我知道一些地址不能被用户使用。他们属于系统。我用我的IP地址作为主机。 – meth 2013-03-17 01:42:11

好吧，显然我不认为你可以连接两个设备这种方式。其中之一必须是服务器。目前我使用SocketKit

https://github.com/unixpickle/SocketKit

但我相信更好的解决办法是可可ASyncSocket。（这是我将要尝试下一步）
