GTTableViewController

GTTableViewController is a light weight subclass of UIViewController that integrates NSFetchedResultsController and UITableView to display data of CoreData.
It has a good scalability, and can be integrated to your project either by inheritance or as a child viewController using datasource methods.
To display the data in UITableView, all you need to do is to customize your own NSFetchRequest and UITableViewCell objects.

How to get started?

Download GTTableViewController and add files under the Class folder into your project.
Installation with CocoaPods. CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like AFNetworking in your projects. See the "Getting Started" guide for more information.
There are two ways to use: inheritance and GTTableViewControllerDataSource.

Inheritance

Write a GTTableViewController subclass and override its methods like this:

NSManagedObjectContext

Return NSManagedObjectContext object which CoreData context you want to use. Default returns from AppDelegate, If you do not override it.

- (NSManagedObjectContext *)managedObjectContext
{
    id appDelegate = [UIApplication sharedApplication].delegate;
    return [appDelegate managedObjectContext];
}

NSFetchRequest

Retrun NSFetchRequest object include the fetch rules and orders. This method must be overrided.

- (NSFetchRequest *)fetchRequest
{
    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
    NSEntityDescription *playerEntity = [NSEntityDescription entityForName:@"Player" inManagedObjectContext:[self managedObjectContext]];
    [fetchRequest setEntity:playerEntity];

    NSSortDescriptor *sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:@"age" ascending:YES];
    [fetchRequest setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]];

    return fetchRequest;
}

UITableViewCell Display

Config your own UITableViewCell. Cell is empty, if you do not override it.

- (void)configCell:(UITableViewCell *)cell cellForRowAtIndexPath:(NSIndexPath *)indexPath fetchedResultsController:(NSFetchedResultsController *)fetchedResultsController
{
    Player *player = [fetchedResultsController objectAtIndexPath:indexPath];
    cell.textLabel.text = player.name;
}

UITableViewCell

Return your own UITableViewCell. Cell is UITableViewCellStyleDefault, if you do not override it.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath fetchedResultsController:(NSFetchedResultsController *)fetchedResultsController
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (!cell) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    [self configCell:cell cellForRowAtIndexPath:indexPath fetchedResultsController:fetchedResultsController];

    return cell;
}
