以编程方式唯一地标识iOS 7及更高版本上的设备

Question

In my Android app I am identifying a device and a SIM card reading the IMEI and IMSI respectively.

How can I do it programmatically on iOS 7 and later? I see that the UUID identifies the app + device, and it changes every time you reinstall it, so it doesn't work for me.

Any ideas?

Answer 1

There is no FIXED (publicly available) ID anymore. UUID is off limits and using the mac address isn't fixed

identifierForVendor changes on reinstall but thats all you have :)
