runtime-dicttomodel's Introduction

runtime-dictToModel

runtime 字典转模型

将后台JSON数据中的字典转成本地的模型，我们一般选用部分优秀的第三方框架，如SBJSON、JSONKit、MJExtension、YYModel等。但是，一些简单的数据，我们也可以尝试自己来实现转换的过程。

快速使用

当我们的请求到的数据不是很复杂, 也不希望引入第三方框架的时候, 可以使用下这个分类, 来实现字典转模型.

1.根据请求数据, 创建对应的模型类, 并根据字典中的键值对定义对应的属性

  • 创建模型原则: 从外层到内存, 一个类型字典对应一个模型
  • 示例程序中, 根据plist, 创建了三个类: ShopItem , AttrModel , ListItemModel

runtime1

  • 注意: 定义的属性名和字典中的键名字一致.

2.在分类中导入最外层模型

runtime2

3.最外层类中导入 NSObject+EnumDict 分类

runtime3

4.遵守分类协议 ModelDelegate, 实现协议方法

runtime4

5.控制器中, 导入最外层模型 ShopItem.h , 解析数据遍历数组, 并字典转模型
