基于iOS平台的客户端应用之食安检的设计与实现 摘 要 在我们的生活中，存在着各种各样的食物。在提倡绿色食品、健康食品的今天，还是有一些食品存在严重安全隐患。接连不断发生的恶性食品安全事故却引发了人们对食品安全的高度关注，要重新审视这一已上升到国家公共安全高度的问题，更要加大对食品安全的监管力度。食品安全关系到广大人民群众的身体健康和生命安全，关系到经济健康发展和社会稳定，关系到政府和国家的形象。食品安全已成为衡量人民生活质量、社会管理水平和国家法制建设的一个重要方面。于是一款成熟的食品安全检测的APP的研究与设计开发已经成为了市场不可或缺的一部分，并且有着广阔的发展前景。 本次设计项目食安检，基于苹果iOS系统，利用智能手机实现食品安全检测的功能。毕业设计完成时，整个应用界面简单明了，操作简洁。用户不仅能够看到自己购买的食品是否安全、符合国家标准，还能够进行其他产品的搜索，让用户能够对于自己购买的食品吃得舒心，买的放心。 本设计所使用的开发环境是Xcode，使用的编程语言是Objective-C。项目主要功能包括产品的展示、搜索以及条形码扫描。 关键词：iOS系统; 食品安全; Objective-C语言; 条形码 Abstract In our lives , there is a wide variety of foods. In promoting green , healthy food today, there are still some serious food safety hazards . Malignant food safety incidents occurred one after another , but sparked great concern about food safety , to re -examine this had risen to the height of a national public safety issues , but also to increase the food safety supervision. Food safety is related to the health and safety of the masses , related to the healthy economic development and social stability , related to the image of the government and the country. Food safety has become an important aspect of a measure of the quality of peoples lives , social management and the national legal system. So APP research and design to develop a sophisticated food safety testing has become an integral part of the market , and there are broad prospects for development. The design project food security, based on Apples iOS system, using smart phones to achieve food safety testing functions. Upon graduation design is completed , the entire application interface is simple , simple operation. Users can not only see if it is safe to buy their own food , in line with national standards, but also be able to search for other products , allows users to buy their own food to eat for comfort, buy the rest assured . This design is used in the development environment Xcode, the programming language is Objective-C. Project features include dis
