I want to ask a question about the Contacts on objective C. I am writing a program which will add the people to the iPhone build-in Contacts by ABPerson. However, I don’t know I can add how many users to the iPhone. Are there some limitations of adding the contacts to the address book? I mean the number of user, adding field or the memory using/management. Thank you.
No. I’ve read user reports 10,000 contacts or more. As long as your code doesn’t leak, you should be just fine. Return with a more specific question if you encounter any problems.
