Question

I want to create an array of ABRecordRef(s) to store contacts which have a valid birthday field.

   NSMutableArray* bContacts = [[NSMutableArray alloc] init];
   ABAddressBookRef addressBook = ABAddressBookCreate();
   CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
   CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

   for( int i = 0 ; i < nPeople ; i++ )
   {
       ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i );
       NSDate* birthdayDate = (NSDate*) ABRecordCopyValue(ref, kABPersonBirthdayProperty);
       if (birthdayDate != nil){
           [bContacts addObject:ref];
       }
   }

The compiler shows this warning:
warning: passing argument 1 of ‘addObject:’ discards qualifiers from pointer target type
I searched the web and found I have to cast ABRecordRef to a ABRecord* to be able to store in a NSMutableArray.

[bContacts addObject:(ABRecord*) ref];

But it seems ABRecord is not part of iOS frameworks. Now how I store ABRecordRef to NSMutableArray?

Answer 1

[bContacts addObject:(id) ref];
