基于iOS电子菜单设计与实现--毕业论文.docxVIP

摘 要 信息技术在全球的广泛使用，不仅深刻地影响着经济结构与经济效率，而且还被作为先进生产力的代表。在经济全球化的今天，信息技术已经成为一种在各个领域取胜的强大武器，例如在军事领域,教学领域,医疗领域等等，当然它也可以被用于餐饮行业。 电子菜单项目的开发使用了苹果自己研发的开发软件Xcode，主要有UIkit框架和Foundation框架组成。电子菜单的项目开发，对数据进行展示主要应用滑动视图控制器UIScrollerView和列表控制器UITableView相结合，在使用UITableView时对cell的复用是此技术的难点，主要避免在cell复用是出现内存泄露状况而导致的程序崩溃，数据的获取和保存应用了FMDB第三方库，对数据库中的数据进行增删改查等操作，此数据库的底层也是对SQLite的封装，开发者应用起来更顺手简介，提高效率，把获取的数据用数据模型接收，这样有利于降低耦合性，使程序更顺畅，代码更健壮。 系统中的基本功能都已经实现，满足用户需求。而且本系统巧妙地将信息技术结合到餐饮业中，大大的节约了餐饮业的成本，同时也兼顾了用户群体的利益，为用户带来一个简洁、易用、方便、美观的点餐平台。 关键词：iOS，SQLite，通知，应用，控件 Abstract The widespread use of information technology in the world, not only has a profound impact on the economic structure and economic efficiency, but also as a representative of the advanced productive forces. In todays economic globalization, information technology has become a powerful weapon to win in all fields, such as in the field of military, teaching, medical field and so on, of course, it can also be used for food and beverage industry. The development of electronic menu items using Apples own research and development of software development Xcode, is mainly composed of UIkit framework and Foundation framework. Project development of electronic menu, the data show the main application of sliding view controller UIScrollerView and UITableView controller combination list, when using UITableView cell to reuse is a difficulty of this technology, mainly in the cell multiplexing is to avoid memory leaks caused by the status of the program crashes, obtaining and preservation of the application of the FMDB third party library data and the data in the database CRUD operations, the underlying database is also the SQLite package, application developers more easily, improve the efficiency of the data received by the data model, it can reduce the coupling, make the program more smooth, more robust code. The basic functions of the system have been realized, to meet the needs of users. And the system cleverly the information technology with the fo
