Unique identifier in ios 7

Question

Until giving up uniqueIdentifier, it was good to use the same identifier, even by uninstalling the application and even erasing the iPhone. After that, I use the MAC address, which also worked before iOS 7, but with iOS 7 it gives 2c: 00: 00: 00: 00: 00. Therefore, I don't get any way to get a unique identifier. If IdentifierForVender is used: it gives a different identifier if I uninstall the entire application of the same provider.

MAC Address: It works fine, but not on iOS 7.

Unique identifier: deprecated.

Please tell me how to get a unique value, even uninstalling the application and even erasing the iPhone (for example, restoring the factory)
