Using induvidual NSFetchedResultsController for each type of fetch

I have a database with many different objects that I need to retrieve. I have settled to use NSFetchedResultsControllers to retrieve and store data. Is it the correct protocol for developers to use multiple NSFetchedResultsControllers? For example:

NSFetchedResultsController *loadDates = ...;
NSFetchedResultsController *loadMoreData = ...;
NSFetchedResultsController *loadMuchMoreData = ...;

Thanks.

In general you should use NSFetchRequest to retrieve data for one-time purposes.

What NSFetchedResultsController is really useful for however is creating a bridge between your data and your UITableViewController subclass. NSFetchedResultsController will monitor all changes to the managed object context that are in the bounds of its predicate and send delegate methods to your UITableViewController subclass so you can update your UI.
