如何编写 iPhone 应用程序来控制公开 telnet api 的设备
我必须编写一个控制设备的 iPhone 应用程序。该设备公开了基于 telnet 的接口。理想情况下，应用程序应该为每个用户提供用户访问控制和可定制性。
我正在考虑编写 C++ 类来使用套接字与设备进行通信。然后可以通过 iPhone 应用程序调用的 Web 服务公开此功能。
然而，当我深入研究时，API 允许您使用 telnet 注册事件，然后您可以在这些事件发生时收到通知。这对我来说有点麻烦。我不知道“推送”方案可以与网络服务一起使用。
首先，到目前为止我还没有为 iPhone 编程过。所以我不太确定可以做什么。所以我在想，为什么不让应用程序在 iPhone 上独立运行，使用套接字直接与设备通信，而不是通过网络服务器。但问题是，这是否可能，其次我认为这会引起安全方面的问题。首先，我们可以控制安全性，因为一切都通过我们的中央服务器进行。有没有一种方法可以在没有中央服务器的情况下处理安全性（即谁有权访问设备）。
很抱歉，这看起来像是一篇杂乱无章的帖子，但我想在这里集思广益。
期待听到您的意见。
I have to write an iphone application that controls a device. This device exposes a telnet based interface. The application should ideally have user access control and customizability for each user.
I was thinking of writing C++ classes that would communicate with the device using sockets. This functionality can then be exposed through web-services that can be called by the iphone application.
However as i looked into it deeper, the api allows you to register for events using telnet and then you can receive notification when those events occur. That kinda put a spanner in the works for me. I for one dont know a "push" scenario can work with webservices.
First off i have never programmed for the iphone so far. So i am not really sure what can be done. So i was thinking if instead of having a webserver to go through, why not have the application independently running on the iphone, directly communicating with the device using sockets. The question though is, is that possible and second i am thinking it would raise a security aspect. First we could control security as everything was going through our central server. Is there a way to handle security (in the sense who has access to the device) without having a central server.
I am sorry that this seems like an unorganized post, but iam trying to brainstorm here.
Looking forward to hear your opinions.

NSPort和NSStream类。Look up the
NSPortandNSStreamclasses.我想做同样的事情。有一个程序在一台计算机上运行，并且想要从 iOS 发送/接收 telnet 命令。使用 Commons 库为 Android 构建了一个 - 它有一个 telnet 客户端 API，但不知道在 Objective-C 中执行此操作的最佳方法（无需编写 telnet 客户端库）。
不过，首先，我在 Google 代码上找到了 OFC 库。看起来有点像 Commons 的感觉，而且似乎有一个 telnet 客户端。你可能会看一下。
I'm looking to do this same thing. Have a program running on one computer and want to send/receive telnet commands from iOS. Built one for Android using the Commons library- which has a telnet client API, but don't know the best way to do it in Objective-C (without writing a telnet client library).
As a start, however, I found the OFC library on Google Code. Looks like something of a Commons-like feel, and there seems to be a telnet client. You might take a look at that.
