Design Of On-line Test Application On Iphone OS Framework

With the rapid development of smart mobile phone, more and more people pay attention on mobile internet currently. A period of mobile communication is coming. iPhone OS pushed By Apple has already been main aspect of operation system in market. Applications used for iPhone OS display pluralism and meticulousness step by step. The on-line test application in this paper mainly uses on iPhone, which implements the function of test in GSDzone official website.This thesis discusses the basic theory and design cycle of this on-line test application, lists the specific design cycle and logical analysis of various modules, summarizes the common tools used in software development and standardizing modules. Due to on-line test application need to establish real-time network link, when the software in runtime, this process deals with plenty of data analysis and data translation which adopts HTTP protocol.This software has two test methods, one is challenging mode, the other is evaluating mode. The question divides into single selection and multiple selection. Question after analysis displays in a certain location, the word size of character is not big enough, due to the limitation of the screen. Gesture function used in this software, which support enlarge and lessen the interface and slide interface. Owing to networks disruption and jitter, the software prone to collapse specially during translating data. This problem has been solved through adding judge and limiting authority in this process. This software could load down from App store now. On the basis of test results, the property of this software is stable.
