I am new to core data and iphone programming so dont mind my silly qn. I couldn't figure out how to mark a attribute as a primary key in the xcdatamodel file or may be outside. I looked around and found some people saying that it is not possible.
I am getting identifier for every object that i am getting, i would need to store that object through core data and i might need to use that identifier in my web service to retrieve additional data. How do i keep the primary key of an entity equal to that identifier, any help is greatly appreciated.
Thanks in advance,

In short you cannot mark an attribute as primary key automatically. You have maintain one by your own.
You can do anyone of the below:
Use [NSManagedObject objectID].
Your own primary key-like system that stores an integer in your model and increments it with the creation of each object
