ios獲取設備其它信息這里就不說了,網上一大堆,也都很簡單,一般信息獲取都有提供方法,今天樓主主要介紹下ipAddress 和 macAddress的獲取方法(WIFI和蜂窩網絡狀態下).
二話不說直接代碼:
首先,咱們要在libraries里加入libresolv.9.tbd
然后,然后就往下看↓....

飛行模式下(也就是獲取失敗默認返回值)

物理地址在非WiFi網絡下獲取不到,沒有解決,有能獲取到的小伙伴分享一下.
另外,其實樓主還想獲取SIM卡手機號以及IMEI,網上看了好多,ios11上都不能實現,有能獲取到的小伙伴分享一下.
說明:上面代碼非樓主本人編寫,最近做這個,在網上搜了一些,測試后整理了一下.
