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*有点方
3.ObjectMapper朋友推荐使用这个
4.swift4.0 Codable,个人也不太喜欢
