objective c - Predicate and distinct objects -


I have the unit unit and tags Relationship to many others

I am using NSFetchedResultsController to manage the data I need unit object by NSFetchedResultsController < / Code> condition is to return to Tag.show == YES . I'm not sure how to feed it all at NSFetchedResultsController Set the unit to unit or tag how to make it

example:

I have 6 Tags objects tag1 ... tag6 and 3 unit objects unit1, unit2, unit 3 . Tag 1, Tag 2 unit 1, tag 3, tag 4 are pointing at unit 2. Tag 1 ... Tags 4 found show == yes condition. So I should finally get the Uni1 and Unit 2 in the NSFetchedResultsController .

On a unit unit "any tag. Show = = Yes "to bring with a prediction.

This unit will return examples that show tags = in one or more related tags examples. Brings different objects back, so you do not have to do anything else

But I do not think the code is capable of changing the color of each variable declared....
