ios - 如何定义一个类获取JSON数据

json

需要处理的JSON数据中一个数组元素如下，请问如何定义一个类获取它的数据（目的是把获取的数据展示在一个tableview的cell中），我需要获取text，user里的screen name和profile_image_url所指向的图像数据。我遇到的问题是在定义一个这样的类时，user是不是要再定义一个类？在类里不能镶嵌一个类吧？如何定义它才能在后续处理中成功地将数据加载在tableview中？

- User是需要再定义一下类的.
- 一个 swift 文件是可以有多个类的；
```
class Results: NSObject {
    var created_at: String? 
    var user: User?
}
class User: NSObject {
    var idstr: String?
}
```
