Unique identifier for an iPhone app
Our server database recognize user based on Device UDID, but now UDID is depreciated in IOS 5.. i m not able to use it... Can anyone please help me to find out "How can we Identify the device?". Thanks in advance.
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).
The agenda for this community driven project is to:
Provide a reliable proxy and replacement for a universal unique device identifier. That is, persistent and sufficiently unique, on a per device basis. NOT use an obvious other sensitive unique identifier (like the MAC address) to avoid further deprecation and to protect device-level privacy concerns Enable the same OpenUDID to be accessed by any app on the same device Supply open-source code to generate and access the OpenUDID, for iOS and Android Incorporate, from the beginning, a system that will enable user opt-out to match Apple’s initial intent
I personally use `Unique Device Identifier'
Works fine, and Apps got approved from Apple as well. =)
U can use BPXLUUIDHandler as an option to UDID which is depreciated in IOS 5
Use This....the easiest and most appropriate way to obtain a unique identifier is to use the mechanisms Apple explicitly provides for obtaining one[[UIDevice currentDevice] uniqueIdentifier].
