  • swift4.0 数据转模型

    swift 4.0时代的到来,说明了swift已经趋于稳定了,已经完全可以入坑了.

    下面就拿最简单的数据转模型来说说,实战一下.

    接口使用:  http://116.211.167.106/api/live/aggregation?uid=133825214&interest=1  

    分别演示下:  1.SwiftyJSON 2.HandyJSON 3.ObjectMapper 4.swift4.0 Codable

    说明:对上面几种方案使用过后1.SwiftyJSON直接对返回数据进行操作,不包含模型转换.个人不太喜欢

    　　　　　　　　　　　　　 2.HandyJSON阿里封装的数据转模型,朋友说这个轮子有点方

    　　　　　　　　　　　　　 3.ObjectMapper朋友推荐使用这个

    　　　　　　　　　　　　　 4.swift4.0 Codable,个人也不太喜欢

    1.SwiftyJSON
