Answer 1

You need to maintain count for contacts array and increment accordingly.
and while creating indexPath you need to set appropriate indexPathForRow: and section count(if required).

- (void)displayPerson:(ABRecordRef)person
{

  ..........

[contacts insertObject:firstName atIndex:0];

NSIndexPath * indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; // you cant do this increment appropriately

 .........
}
