Design And Implementation Of Fund Transaction Subsystem In Fund Management System Based On IOS

In recent years, the rapid development of the Internet, and with the function ofthe mobile phone is more and more strong, the mobile phone network speed fasterand faster, people gradually began to use the mobile phone to connect to thenetwork, to obtain information on the network. The IPhone intelligent mobile phonebased on IOS is very popular because of its unique design, excellent performanceand good experience.My internship units is a financial information service providerin Hangzhou. Combined with the company’s resources and the IPhone environmentmobile phone application hot, it is necessary to build up a mobile phone applicationcan help users manage funds, the mobile phone application can not only help usersaccess to different kinds of fund informations, can also help the user do some fundtransaction operations through the mobile phone at any time.This paper mainly from the domestic related research situation of the system, adetailed description of the system in different sub module needs analysis, outlinedesign, business process and the concrete realization method and framework.Themobile phone application design pattern framework of Model View Controller, thedata structure and the page display layer to separate, to ensure the overall structureclear, avoid confusion code.At the same time, the system is running on the mobileplatform, so it is very important that we must ensure good network request speedand great user experience.The result of this paper is I has designed and realized a fund transactionsubsystem.The fund transaction subsystem relates to the user fund purchase,redemption, conversion, dividends, view records, value position gain integraloperation and function. The application available to users of these functionsinformations, at the same time,to ensure the safe is also important.Finally,for the different modules in the system, designed the different test casesto test, in order to ensure the correctness of the system, at the same time as themobile phone application, also need to use Instruments in Xocode and capture toolsfor code detection, memory management, network request, performance testing,performance ensure good. The test results show that the system satisfies the definedrequirements. The work of this paper is a part of a fund management system project, theproject has passed the test and detection, and now release in AppStore.There areabout5000active users every day.
