Storing data to NSUserDefaults

Question

Answer 1

Well, Apple's recommendation is to store the record identifier, the first name, and the last name. You can then try retrieving the contact from the address book by the identifier and, if the record isn't found or if it's not the right person, try retrieving by first and last name (since record identifiers may change depending on the source of your address book data).

This may or may not be what you want, depending on why you're storing the data. But, you could pretty easily put those three values into an NSDictionary and write the dictionary to NSUserDefaults.
