Design And Implementation Of Intracompany Instant Messaging Based On IOS Client

The fundamental purpose of the company internal instant messaging system is to promote the intracompany employee's work efficiency, to make benefit for the communication between employees, With the continuous development of modern corporation and Internet technology,more and more corporations have applied the company internal instant communication system to daily work, especially the system based on mobile terminal. Therefore, this topic has been proposed that the design and implementation of company instant messaging system based on iOS.According to the theory of functional division and the method of module design, the program has better performance on communication fluency and extensibility of the system.Through the analysis of the importance of instant messaging system for enterprise and the significance, the author first has carried on the study to the relevant technology of the instant messaging system research, which focus on the basic framework of iOS, the required modules and instant messaging system using instant messaging mechanism analysis and choice; Then, the author of enterprise instant messaging system based on the iOS system functional requirements and non-functional requirements analysis, divided the iOS enterprise instant messaging system main interface, contacts, groups, functions, session,set up five basic functions modules. The core work of this paper is on the iOS instant messaging system's overall function and server architecture design, by using MVC development idea, based on C/S architecture of iOS system framework for building, focusing on the main interface of the system module, contact module, group module, session module and process of setting function module design, and through the design classes and functions on the system module development,cooperate with the design of the server data port, completed the basic function of instant messaging system.Through the formulation of test cases and test environment to the main interface modules respectively, which include contact module,group module, real-time communication module and data storage module the function of the corresponding test. Test mainly starts from the angles of functional implementation, system compatibility and user experience, and the memory of the system were analyzed and optimized.
