Question

id满足如下条件：

ps：我知道有vendor id和advertising Id，问题是如何满足条件3
pps：之前把第一次生成的id存储在keychain中，不过恢复出厂后会丢失...

Answer 1

There is no solution to this problem now. Apple prohibits identification of devices
UUID is basically enough

Answer 2

i Apple doesn’t want you to get it and prohibits you from labeling your phone. You can only use OpenUDID or UUID+keychain, but neither is a perfect solution and you must make a choice

Answer 3

3 seems to be unable to satisfy

Answer 4

I studied this problem one day before
The final answer is that there is no solution
My final solution is
I work on smart hardware
I asked the hardware side to tell me the unique ID of the hardware

Answer 5

You can get the deviceId of the device, this is accurate

Answer 6

Someone has already answered it. If there is no solution, you can only use UUID

Answer 7

Apple is awesome, no solution

Answer 8

There is a UDID framework that can generate a unique identifier by yourself, but it is not a real UDID, just a simple unique identifier. Search it yourself.

Answer 9

OpenUUID
