This is class that helps you to aliviate the Core Data boilerplate. Now you can go to your AppDelegate remove all the Core Data related code and replace it with:

- (void)applicationWillTerminate:(UIApplication *)application
{
    [[ANDYDataManager sharedManager] persistContext];
}

Then in your NSFetchedResultsController backed app (attached to your main context). You can do this:

#pragma mark - Actions

- (void)createTask
{
    [ANDYDataManager performInBackgroundContext:^(NSManagedObjectContext *context) {
        Task *task = [Task insertInManagedObjectContext:context];
        task.title = @"Hello!";
        task.date = [NSDate date];
        [context save:nil];
    }];
}

BOOM, it just works.

(Hint: Maybe you haven't found the best way to use NSFetchedResultsController, well here it is.)
