你有接触

NSArray *allPeople = ((__bridge_transfer NSArray *)ABAddressBookCopyArrayOfAllPeople(addresbook)); 

for (int i = 0; i < allPeople.count; i++) { 
    ABRecordRef *person = (ABAddressBookRef *)[allPeople objectAtIndex:i]; 

    NSDate *creationDate = ((__bridge_transfer NSDate*)ABRecordCopyValue(person, kABPersonCreationDateProperty)); 
    NSLog(@"Creation date: %@ of entry: %@", creationDate, person); 
}
