仿面包旅行(ReactiveCocoa+MVVM)

此项目是将面包旅行跟面包猎人两个应用结合。用ReactiveCocoa+MVVM,最开始想用公司项目,但考虑到要脱敏,不方便。项目中的所有接口都是抓包,只是用来学习练手之用。

由于面包旅行APP已经与2021年8月关闭服务,所以此项目的所有API将无法访问。但不妨碍项目作为参考之用,之后可能会使用新的API的

注意:直接运行项目出现 xxx not found 的错误,请先cd到项目路径下执行:pod update 即可。


ReactiveCocoa

ReactiveCocoa(简称为RAC),是由Github开源的一个应用于iOS和OS开发的框架,RAC具有函数式编程和响应式编程的特性。由于项目是使用的OC,所以我使用的是ReactiveCocoa2.5。如果你的项目是纯OC,也可以使用ReactiveObjC

MVVM

MVVM是一个UI设计模式。它是MV模式集合中的一员。MV模式还包含MVC(Model View Controller)、MVP(Model View Presenter)等。这些模式的目的在于将UI逻辑与业务逻辑分离,以让程序更容易开发和测试。其中 ViewModel 的主要职责是处理业务逻辑并提供 View 所需的数据,这样 VC 就不用关心业务,自然也就瘦了下来。ViewModel 只关心业务数据不关心 View,所以不会与 View 产生耦合,也就更方便进行单元测试。

MVVM模式依赖于数据绑定,由于iOS没有数据绑定框架。但幸运的是ReactiveCocoa可以很方便的实现这个,所以ReactiveCocoa是实现MVVM的最佳方式。不通过ReactiveCocoa也可以实现MVVM一样可以实现,感兴趣的可以看这篇博客

更新

2021.6

  • 完全重写了此项目
  • 实现新的、更加完善、易用的路由系统
  • 基于新的路由系统,重构了架构
  • 将长时间积累的基础组件开源,包括网络请求、RAC等等组件
  • ……

To-Do list

  • [ ] 使用Texture重写页面
  • [ ] 实现主题切换
