I am working on an app where i m storing DeviceIdentifier in keychain(thanks to deprecated method in ios6 to fetch unique identifier all the time)for later use to identify that it is a allowed device to use app.
i am storing it in keychain , what i want to achieve is if device is in recovery mode or if someone restoring a backup i want to send request to the server to deactivate this device identifier which is stored in keychain, before keychain get deleted.
is it achievable or any other suggestion?
whenever the server communicates with the device, check if the device identifier exists in the keychain, if not, then send a call back to server asking to deactivate the device identifier from the server.
