swift 4.0時代的到來,說明了swift已經趨於穩定了,已經徹底能夠入坑了.git

下面就拿最簡單的數據轉模型來講說,實戰一下.github

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

分別演示下:  1.SwiftyJSON 2.HandyJSON 3.ObjectMapper 4.swift4.0 Codableswift

說明:對上面幾種方案使用事後1.SwiftyJSON直接對返回數據進行操做,不包含模型轉換.我的不太喜歡api

　　　　　　　　　　　　　 2.HandyJSON阿里封裝的數據轉模型,朋友說這個輪子有點方app

　　　　　　　　　　　　　 3.ObjectMapper朋友推薦使用這個ide

　　　　　　　　　　　　　 4.swift4.0 Codable,我的也不太喜歡ui

1.SwiftyJSON　　spa
