面向iOS的师生即时交流通信系统设计

Design of instant communication system for teachers and students in iOS

师生之间的沟通是教学工作的重要环节,即时通信是师生沟通交流的重要工具。针对目前流行IM工具安全性问题,本文面向i OS设计自主软件。研究内容包括四个方面:一是,设计由客户层、连接层、逻辑层、数据层和安全层构成的多层逻辑结构;二是,研究由XMPP、SMS和SMTP构成的XMPP协议架构;三是,设计由客户端和服务端组成的系统功能;四是,基于Xcode进行程序设计。本文充分吸收了各种技术的优点,为开发安全可靠的师生即时通信系统奠定了基础。

Communication between teachers and students is an important part of teaching work, instant messaging is an important tool for teachers and students to communicate in. Aiming at the security problem of the popular IM tools, this paper is based on the i OS design independent software. The study includes four aspects: First, the logical design of a multi-layer structure consisting of client layer, the connection layer, logic layer, data layer and the security layer; second, the study XMPP protocol architecture consists of XMPP, SMS and SMTP; Third, system function is designed by the client and server component; Fourth, based on Xcode to conduct programming design. This article has fully absorbed all the advantages of technology for teachers and students to develop secure and reliable instant messaging system laid the foundation.
