摘　　要：随着移动互联网的兴起和智能终端平台的普及,人们对移动理财的需求越来越大,然而市场上并没有一款简单易用、功能广泛的在线理财App产品。对此,文中基于"产学研"的需要提出社区金融App项目,完成基本UI的设计与实现,功能模块API的开发、分析前后端数据交互、JSON解析等。实验重点研究和解决了多线程和缓存框架的选取和代码实现的问题。首先分析了并发操作可能存在的问题,以及多线程技术是如何予以解决的,具体讨论了GCD框架的优势和工作原理;然后分析了缓存对App的重要性以及不同缓存策略的适用场景和工作流程;最后在实际项目中组合使用不同的缓存策略完成所需要的功能。阐述了未来开发的重点在于统一两大移动平台,并指出了未来App开发的重点在于混合App的开发。With the rise of mobile Internet and the popularity of intelligent terminal platform,people’s demand for mobile finance is growing.However,there is not a simple and wide range of online financial App products on the market.Therefore,we put forward the community financial App project based on the requirement of“production,learning and research”,which completes the design and implementation of basic UI,development of functional module API,analysis of front and back data interaction,JSON analysis and so on.The experiment focuses on solving the selection and code realization of multi-thread and the cache framework.First we analyze the possible problems of concurrent operation and how to solve it,and then discuss the advantages and working principles of GCD framework.After that,the significance of caching to App,the application scenarios and workflow of different caching strategies are also analyzed.Finally,different caching strategies are combined to fulfill the functions needed in practical projects.In addition,we expound that the focus of future development is to unify the two big mobile platforms,and point out that the focus of future App development lies in the development of hybrid App.
