Question

I am really confused about this.

I see situations where [[NSFetchedResultsController sections] count] is used.
Then there are these situations, [[self.fetchedResultsController fetchedObjects] count].

Now i understand what the latter one is doing. that just makes sense to me.
But i don’t understand the first one regarding the sections.

The document doesn’t define sections. It actually defines it by using the term “sections” with its definition.

thanks.

If you set a sectionNameKeyPath: in the initWithFetchRequest:... call, then the fetched results controller will group the results into sections, corresponding to the sections of a table view.

So [[NSFetchedResultsController sections] count]is the number of sections and [[self.fetchedResultsController fetchedObjects] count]is the total number of all fetched objects.
