NSFetchRequest setFetchOffset in NSFetchedResultsController

Question

I would like to know if setFetchOffset should be expected to work in NSFetchedResultsController.

Given a UITableView that displays such rows from NSFRC:
1
2
3
4
5

I expected adding this line:

[fetchRequest setFetchOffset:1];

eg. line 207 here: http://github.com/mandersen/FetchOffsetCase/blob/master/Classes/RootViewController.m

As a result, UITableView strings appear, for example:
2
3
4
5

But this does not change the values ​​displayed in the table.

Answer 1

setFetchOffset .

, NSFetchRequest setReturnsDistinctResults :

NSDictionaryResultType

Answer 2

, 2, 3, 4, 5, ? , , . , 2- 6- , NSFetchRequest.
