Memory leak problem has been resolved but application is crash when I access the contact and pop to navigation controller again push and accessing the contact, repeating this process 3-4 time and app will crash.

thanks in advance :)
回答1:
You are using the wrong array count value. Try:
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBook, source, kABPersonSortByFirstName);
CFIndex nPeople = CFArrayGetCount(allPeople);
BTW I've seen this code before with the same error. Where did you get it?
