IOS - TCP IP崩潰

我有一個TCP流連接由一個發送聯繫人的巨大的NSDictionary，一個，從手機到服務器。如果NSDictionary有50個條目，它就可以，但發送大約150個155個聯繫人後，大約有200個應用程序崩潰。我認爲這可能是一個內存問題，或者流連接有一些限制？如果存在內存問題，就像我在ARC上一樣，我該如何解決它？IOS - TCP IP崩潰

響應處理（其中我認爲這可能是問題，特別是因爲流越來越關閉了很多次）：

（無效）流：（NSStream *）theStream的handleEvent：（NSStreamEvent ）streamEvent {

你必須讓一些傳輸數據的代碼。我們無法猜測你可能寫錯了什麼。 –

我使用代碼處理服務器的響應來更新問題。我認爲問題在於流何時關閉。我試圖在這一點上重新啓動流。 –
