Design And Implementation Of Take-out Application Based On IOS

In recent years, China's mobile application industry continues the growth rate of 50% in recent years, the domestic smart mobile terminal devices continue to emerge. At the same time, China's online ordering market within the next two years will continue to maintain more than 40% of the growth, 2016 China's catering industry o2 o market size is expected to exceed 160 billion yuan. Data show that the online ordering market in a period of rapid growth, mobile terminal ordering methods will gradually become a trend of eating. IOS mobile operating system is stable and safe and has good user experience, iOS application rate of return is much higher than the Android and Windows Phone operating system. Therefore, the topic, design and implementation of take-out Application based on iOS has a strong practical significance.First of all, the iOS development platform related technologies, Native, Web, Hybrid three kinds of APP development model, based on the MVC iOS development model, GPS, E-OTD, A-GPS three kinds of mobile positioning technology are introduced and analyzed in this paper. Through the analysis and comparison of three kinds of APP development mode and mobile positioning technology, this paper finally uses MVC Native development model and A-GPS positioning technology.And then, it introduces the take-out client demand analysis from the business, functional and non functional three aspects, design system architecture and the overall process of the take-out client,it introduces commodity, shopping, order, positioning, users function module of the client, then from three aspects of animation, interactive network speed, memory management of the client has been optimized.Finally,it introduces and explains test method of system, this paper adopts the unit testing, integration testing, system testing and network testing method, system testing including interface and performance testing. The results show that the client can complete the functional requirements well.
