我正在开发一个由swift和objective c一起编写的套接字基础应用程序。在这个项目中，客户端（Mobile Platform）连接到由asp.net框架编程的服务器套接字。现在，我尝试通过iOS的默认套接字库连接和传输数据（通过输入流和输出流并将它们连接到服务器）;但是这个自定义库在特殊情况下无法正常工作。例如，当接收到的数据很大时，我的socket类通过将它们分成2或3部分来获取输入流中的数据，或者当我的应用程序强行退出并且用户在Web面板中执行某些操作，然后再次运行app时，应用程序什么都没有。
所以请给我一个合适的图书馆或指导我解决我的套接字类问题。
请快速帮助我。我有时间.... :(
我应该说它是我的socket类，由Objective c编写！
这是我的套接字类代码：
