基于iOS的电子菜单设计与实现--毕业论文

河北地质大学本科生毕业设计I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，控件河北地质大学本科生毕业设计IIAbstractThewidespreaduseofinformationtechnologyintheworld,notonlyhasaprofoundimpactontheeconomicstructureandeconomicefficiency,butalsoasarepresentativeoftheadvancedproductiveforces.Intoday'seconomicglobalization,informationtechnologyhasbecomeapowerfulweapontowininallfields,suchasinthefieldofmilitary,teaching,medicalfieldandsoon,ofcourse,itcanalsobeusedforfoodandbeverageindustry.ThedevelopmentofelectronicmenuitemsusingApple'sownresearchanddevelopmentofsoftwaredevelopmentXcode,ismainlycomposedofUIkitframeworkandFoundationframework.Projectdevelopmentofelectronicmenu,thedatashowthemainapplicationofslidingviewcontrollerUIScrollerViewandUITableViewcontrollercombinationlist,whenusingUITableViewcelltoreuseisadifficultyofthistechnology,mainlyinthecellmultiplexingistoavoidmemoryleakscausedbythestatusoftheprogramcrashes,obtainingandpreservationoftheapplicationoftheFMDBthirdpartylibrarydataandthedatainthedatabaseCRUDoperations,theunderlyingdatabaseisalsotheSQLitepackage,applicationdevelopersmoreeasily,improvetheefficiencyofthedatareceivedbythedatamodel,itcanreducethecoupling,maketheprogrammoresmooth,morerobustcode.Thebasicfunctionsofthesystemhavebeenrealized,tomeettheneedsofusers.Andthesystemcleverlytheinformationtechnologywiththefoodandbeverageindustryin,greatlysavesthecostoffoodandbeverageindustry,whilealsotakingintoaccounttheinterestsoftheusergroups,bringasimple,easytouse,convenient,beautifulorderingplatformfortheuser.Keywords:iOS,SQLite,notification,application,control河北地质大学本科生毕业设计III目录摘要..............................................................................................................................................I第1章前言................................................................................................................................11.1课题开发背景...................................................................................................................11.2电子菜单app框架设计开发的现实意义.......................................................................11.3论文内容和结构...............................................................................................................2第2章电子菜单应用开发技术简介.............................................................................................32.1Objective-C简介...........................................................................................................32.1.1iOS系统................................................................................................................32.1.2核心操作系统层和核心服务层...........................................................................42.1.3应用程序框架.......................................................................................................52.2SQLite数据库介绍.........................................................................................................52.3Xcode................................................................................................................................6第3章电子菜单app需求分析....................................................................................................83.1电子菜单app的可行性分析...........................................................................................83.2电子菜单app功能需求分析...........................................................................................9第4章电子菜单app设计..........................................................................................................124.1辅助功能设计.................................................................................................................124.1.1数据库操作功能.................................................................................................124.1.2跳转动画功能.....................................................................................................124.2模块功能设计.................................................................................................................124.2.1登陆和语言选择模块.........................................................................................124.2.2历史菜单模块.....................................................................................................134.2.3历史菜单详情模块.............................................................................................144.2.4菜品介绍模块.....................................................................................................154.2.5我的菜单模块.....................................................................................................164.2.6送单模块................
