Is it possible to run persistent tcp listening socket on iOS, even when my App is not the foreground app?

Question

The iOS APIs allow me to open listening sockets for example using the ServerSocket class, however if my App is not in the foreground I assume I won't receive any requests sent to the socket. Is there a way I can keep the listening socket open in the background? Thanks!

经过进一步的研究，我现在相信在大多数情况下，iOS上的监听套接字仅在您的应用程序为前台时才有用。

我发现的唯一允许后台持久监听套接字的方法会滥用API的其他部分，例如位置API，因此不适合对此功能进行学术演示。
