ios獲取裝置id總結
udid
獲取：[[uidevice currentdevice] uniqueidentifier]
廢棄：ios6
idfv
獲取：[[[uidevice currentdevice] identifierforvendor] uuidstring]
適用：ios6.0+
例子：95955f33-bfbd-48ba-a630-866d2dae482d
idfa
獲取：[[[asidentifiermanager sharedmanager] advertisingidentifier] uuidstring];
適用：ios6.0+
例子：9c287922-ee26-4501-94b5-dde6f83e1475
mac位址
簡介：mac位址在網路上用來區分裝置的唯一性，接入網路的裝置都有乙個mac位址，他們肯定都是不同的，是唯一的。一部iphone上可能有多個mac位址，包括wifi的、sim的等，但是itouch和ipad上就有乙個wifi的，因此只需獲取wifi的mac位址就好了，也就是en0的位址。mac位址就如同我們身份證上的身份證號碼，具有全球唯一性。但在ios7之後，如果請求mac位址都會返回乙個固定值。
廢棄：ios7.0+
