UIDevice uniqueIdentifier deprecated - What to do now?
(32 answers)
Closed 5 years ago.
In my app, I am trying to get all information of the device and to be displayed in app screen.
I got some of the informations, but not getting code to obtain UDID, Serial number and model identifier of a device, what we can able to see in iTunes.
I can able to get UUID, but my request is to get UDID of the device. I got some apps in which they are getting device info like this.
I will be very helpful if I get any solution in this.
Thanks in advance.
You can't as of iOS 6.

Money quote:
As reported by 9to5Mac (and confirmed by Macworld), Apple alerted
developers of a cut-off date for new apps or app updates that access
an iOS device’s UDID (Universal Device ID), an area of security and
privacy concern.

Extended money quote:
With iOS 6 Apple has also completely eliminated its controversial
Universal Device IDs (UDID) and replaced it with a more
privacy-friendly way for application vendors and advertisers to
identify specific devices, Hall said,
Apple’s UDIDs are basically a set of alphanumeric characters that are
used to uniquely identify an iPhone or iPad. The numbers are designed
to let application developers track how many users have downloaded
their application and to gather other information for data analytics.
From the same article, the way to go now is:
With the new iOS 6 the company has gone one step further by
eliminating UDIDs completely and replace with a set of three new devie
identifiers. One is a vendor specific identifier that can be used by
application vendors to recognize specific devices, another is designed
for use by online advertisers and the third is an application-specific
ID. Unlike UDID’s, the new identifiers are not persistent and can be
cleared, though the device has to be completely reset to get rid of
the advertiser identities, Hall said.
In conclusion, the correct way is to either (a) use UUID or (b) ask your user for the device's UDID.
You can use this (Swift 3):
UIDevice.current.identifierForVendor!.uuidString

Unique Identification of iOS device for iOS 7.0 and above
(6 answers)
Closed 6 years ago.
In my iOS app, I have to restrict the user to use iOS app per device. To do this I found a solution that we can use the UUID (Universally Unique Identifier) or UDID (Unique Device Identifier). But according to this answer I can't use UUID, because if app gets deleted or reinstalled UUID has been getting changed and I don't want this. Also Apple rejects apps if app uses UDID.
Is there any way to identify iOS device uniquely.
Apple has done away with the approach of UDIDs and will reject apps that use the same for unique device identification.

What you are looking for is Vendor ID
I'm using this library for my projects, and it's working like a charm, please try :
https://github.com/blackpixel/BPXLUUIDHandler
easy to use :
Import BPXLUUIDHandler.h
Retrieve the UUID with
[BPXLUUIDHandler UUID]
Thats all...
Here is some info from project's github page :
As of iOS 5, Apple has deprecated the device unique identifier api and
hasn’t provided a friendly Obj-C replacement, instead recommending
CFUUIDCreate and NSUserDefaults.
CFUUIDCreate isn’t very complicated and neither is NSUserDefaults, but
this solution fails in a few different ways:
It’s not a quick one-shot call to get the UUID; you have to write your own wrapper to make it friendly
It doesn’t persist; deleting the app blows away the UUID (can be persisted if stored in the keychain though)
There’s no way to share it between apps
I am developing an App using UIDevices IdentifierForValue to track users behavior. In the present we know that under the scenarion shown below, value of IdentifierForVendor will change:
App uninstall and install again
As we know that for mobile device, there`re some scenario that we need to take into consideration. So how about the value of IdentifierForVendor in the following circumstances:
If subscriber change one`s SIM but still using the same phone
If subscriber use the same SIM but change to another phone. For example, one stop using iphone 6 and use iphone 6S instead with data restored from iTune`s backup data.
If subscriber use another Apple ID in the same phone.
Any ideas? Any help is greatly appreciated.
identifierForVendor doesn't take into account the SIM card or Apple ID. It is alternative to UDID that doesn't allow tracking specific device and it is constant for device until every app of the vendor on that device is uninstalled. I used this identifier and switched SIM and Apple ID in the past and I didn't notice the identifier changing.

i am doing iOS app having a concept of sending verification code to the mobile no from the same mobile so that it will get verified and give sms back to me. But i need some unique id for that process.Same this kind of process is using by the whats app and other chatting apps.
1)my problem is i am able to send the message to the same mobile no and receiving message from it but i need some unique identification number to the particular mobile. so that if we place sim card in the other mobile the unique identification in may not collide .
As apple has stopped accessing device UDID's programmatically. You can use vendor id as unique identifier. Vendor id is different for same app on different device.
If I am correct you are looking for an unique identification for a specific mobile number not for the device. UDID will be different for different devices and vendor id will get changed when the vendor apps are deleted. The only way is to use the mobile number as the identification number.
you can use OpenUDID.
OpenUDID is a drop-in replacement for the deprecated uniqueIdentifier property of the UIDevice class on iOS (a.k.a. UDID) and otherwise is an industry-friendly equivalent for iOS and Android, and most recently Windows C# and Silverlight (see links above).
Here is the link:
https://github.com/xaviermichel/OpenUDID
You app will not be rejected because of OpenUDID. OpenUDID supports from version 5
I have done a lot of research on this so please read the question before marking this as similar to some other question.
Our app needs to uniquely determine an iPhone such that even when user completely wipes a phone, when he runs our app we can be sure that it is the same device. The most important thing is we also need to determine devices over multiple Apple ID users so suggestions containing Keychain access and uniqueVendorID might not work as those change when another user starts using that phone. And as I have read using MAC addresses and old UDID for devices is not longer available as of iOS 6.0. I went through [UIDevice identifierForVendor] but this NSUUID changes when all the app by the same vendor has been uninstalled Reference.
I have looked through these resources:
UIDevice uniqueIdentifier Deprecated - What To Do Now?
and
What is a long-term method I can use to uniquely identify an iOS device?
I can not disclose the nature of work that my app performs due to non-disclosure, but to clarify what I require:
Multiple users might use our app on same phones, I need a way to know that the device user A used before and has reported to have handed over to user B is the same device on which our app was run. Is there any way to achieve this?
There's no way to achieve this.
If it's really the case that different users might use your app on the same device after a factory reset of the device, then what you want is not possible. Apple deprecated UIDevice uniqueIdentifier which would have been the way to do this.
as long as they dont restore/wipe the device identifierForVendor is ok

How to get IMEI on iPhone?
(7 answers)
Closed 2 years ago.
I need to find a way to get the IMEI number of an iPhone device. This question is not a duplicate.
I have gone through several forums including SO, and had no luck finding an answer.
Some say Apple doesn't allow developers to see the IMEI number (SO post), and some say to use UDID instead (SO post). Some say that UDID is deprecated (in iOS 7).
I need to know the following:
1.) Does Apple permit developers to retrieve the IMEI number of the device?
2.) How can i programatically do it?
3.) In case if Apple doesn't allow developers to gather the IMEI number, do they provide any other unique number for the device?
4.) Some suggest to use Telephony framework. If i do so, will apple reject my application?
Apple does not allow you to identify a device any more.
UDID, MAC address and all other device identifiers are no longer accessible or allowed by Apple.
Apple suggest that you use either UUID (which you will need to store your self or), identifierForVendor or advertisingIdentifier.
Apple is now also rejecting app that use the advertisingIdentifier and not showing any advertisements apps.
Any means to get the IMEI number are using private methods, which is also not allowed by Apple anymore. And your mobile app might/will get rejected because of this.
Unfortunately, there is no way to get a unique identifier for a device which will always remain the same. Apple no longer allows you to access the UDID. And in iOS 7, all devices' MAC addresses return the same value, so that is no longer useful either.
However, iOS does now give access to two types of identifiers which can be used to identify a device. They are:
Vendor ID - [UIDevice identifierForVendor]. This is a unique identifier which is the same for all apps from the same vendor or company. It will remain the same, so long as the user has at least one app from the vendor installed on their device. So if you have 3 apps, the vendor ID will remain the same unless the user uninstalls all three apps, and then reinstalls. This is not so useful if you only have one app - if the user deletes it and then reinstalls it, it will change.
Advertiser ID - [UIDevice advertisingIdentifier]. This is a unique identifier meant for advertising purposes. But if you use it for non-advertising purposes they, for the most part, won't care. Under most circumstances, the advertising identifier will not change, even if the user deletes and reinstalls the app. However, there is an option in the iOS settings to reset the advertising identifier, which will change it. This is meant to that users can choose to disassociate themselves from any advertising information which has been collected about them. But this is a very advanced setting and I doubt that many users would do this frequently enough that it would be a problem for you.
You can obtain IMEI using private frameworks -See this Question but probably your app will be rejected from app store then.
If you want to obtain some device identifier to use in your application you must use uniqueIdentifier property defined in UIDevice class
(Available in iOS 6.0 and later):
NSString *UDID = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
You can save UUID in keychain and user it as unique number. It won't change until user will reset iOS.
If you want to obtain the IMEI there is no way (on a non-jailbroken device). If you wish to identify the user take a look at this answer. Please pay attention to all documentation/answers written before iOS7 since things have changed.
