Design And Implementation Of Tibetan-Cninese Dictionary System Based On IOS Platform

Most of the dictionary software on the market is mainly based on Chinese language services.Currently,dictionary translation software based on minority languages of mobile terminals is still not very popular.This paper is based on the research and development of the Tibetan-Chinese dictionary APP developed by Apple's mobile operating system iOS,providing users with the service of translating Tibetan into Chinese.Firstly,this paper describes the current status of the Tibetan-Chinese electronic dictionary,and combines the advantages of the current mainstream electronic dictionary to design and analyze the system's functional structure and technical route.Secondly,it introduces the theory and technology used in the development of the system.Including the iOS operating system used in the development of the system,the Xcode integrated development environment,the Objective-C language used in programming,the MVC architecture mode adopted in the engineering structure,and the corresponding logical structure and function of the software.Dictionary tree algorithm and Coredata database for local and persistent storage of Tibetan and Chinese to ensure data matching speed and accuracy;again,through feasibility analysis,functional requirements analysis,client use case analysis and non-functional requirements Analysis and other aspects of the system requirements analysis,analysis of the overall function of the system to the detailed design and implementation of the entire system,including the technical route,overall architecture,overall functions,collection,deletion operations.The client obtains data through connection and binding with the Coredata database.Finally,the black box test and the white box test are designed according to the characteristics of the function modules of each module.In the integration test,the client successfully passed all the test cases.The Tibetan-Chinese electronic dictionary system of this paper realizes the function of searching words in the demand analysis.My words,collection and deletion functions and other functions have been tested,indicating that the software has fulfilled the expected requirements and can run stably on the mobile terminal.
