Objective C NSStream連接總是被拒絕

我想在可可和可可觸摸中設置一些NSInput/Output流。我試圖通過Wifi在我的Mac和iPod之間建立連接。不管怎樣，雖然我總是得到連接拒絕錯誤。我有每個設備的地址硬編碼（因爲它只是一個測試）。我基本上遵循蘋果的文檔無濟於事。我一直堅持這幾天。任何幫助將不勝感激！Objective C NSStream連接總是被拒絕

我使用該鏈接的代碼https://gist.github.com/thefifthcircuit/446256。我可以建議你看看這個 – meth 2013-03-17 01:28:13

該代碼適合你，我認爲？我以前看過那個頁面，但它看起來和我的完全一樣，所以我沒有多想。我會仔細看看它。順便說一下，你的地址是什麼？我使用的東西像10.0.1.5（本地連接）這是正確的嗎？ – Sequence 2013-03-17 01:38:59

嗯，我沒有太多有關地址的信息，但因爲我知道一些地址不能被用戶使用。他們屬於系統。我用我的IP地址作爲主機。 – meth 2013-03-17 01:42:11

好吧，顯然我不認爲你可以連接兩個設備這種方式。其中之一必須是服務器。目前我使用SocketKit

https://github.com/unixpickle/SocketKit

但我相信更好的解決辦法是可可ASyncSocket。（這是我將要嘗試下一步）
