ios - Delegate doesn't seem to fire from RBQFetchedResultController -

-

i'm struggling delegates fire using rbqfetchedresultcontroller (https://github.com/roobiq/rbqfetchedresultscontroller). controller drop-in replacement nsfetchedresultcontroller when using realm database. wondering if has had troubles setting delegate? frc perform fetch, doesn't notify delegate when new information needs shown.

edit:

 - (rbqfetchedresultscontroller *)frc {      if (_frc != nil)      {          return _frc;      }      else      {          _frc = [[realmcontroller sharedinstance] createformtemplatefrc];          _frc.delegate = self;          return _frc;      } }

this code shows how created , set delegate frc.

the issue needed use rbqnotificationmanager class methods register changes.
