### JVRCoreDataCollectionViewDataSource

JVRCoreDataCollectionViewDataSource aims to make your collection view controllers lighter by encapsulating logic from NSFetchedResultsControllerDelegate and UICollectionViewDataSource.

Using JVRCoreDataCollectionViewDataSource is really simple, you only need a few lines in your view collection controller class.

@interface MyViewController()
@property (nonatomic, strong) JVRCoreDataCollectionViewDataSource *dataSource;
@end

@implementation MyViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.dataSource = [JVRCoreDataCollectionViewDataSource dataSourceForCollectionView:self.collectionView 
                                                          withFetchedResultsController:self.fetchedResultsController
                                                                  withCellConfigurator:[[MyCellConfigurator alloc] init]];
    }
    
@end

As you might have noticed, you will also need a cell configurator class (MyCellConfigurator in this example), which has to implement the methods of the JVRCellConfiguratorDelegate protocol. See the project page for details about how to do this.

CocoaPods is a great way to add third party libraries to your project so I recommend using it for JVRCoreDataCollectionViewDataSource as well. Add the following line to your Podfile:

  pod 'JVRCoreDataCollectionViewDataSource'

This will also add the previously mentioned JVRCellConfiguratorDelegate as dependency.
