ios - tcp ip crash

Question

我有一个tcp流连接，可以将一个巨大的NSDictionary联系人一个接一个地从手机发送到服务器。如果NSDictionary有50个条目，它就可以了，但是在发送大约150个155个联系人后，大约有200个应用程序崩溃。我认为这可能是一个内存问题，或者流连接有一些限制？如果存在内存问题，例如我使用ARC，我该如何解决？

响应处理（我认为这可能是问题，特别是因为流已经关闭了很多次）：

我使用了robbiehanson的CocoaAsyncSocket库，它更快更稳定：

如果你必须建立套接字连接我强烈建议使用它，它会更快更简单（至少对我而言）。
