A protocol for classes responsible for the creation and configuration of UICollectionViewCell or UITableViewCell objects. This class is a meant to be used with my JVRCollectionViewDataSource and JVRBaseTableViewDataSource projects

Configuring Cells

Cell configurator classes aim to encapsulate the logic that previously belonged in the tableView:cellForRowAtIndexPath:/collectionView:cellForItemAtIndexPath: method found in the UITableViewDataSource/UICollectionViewDataSource protocol. They can be used to return the reuse identifier for a cell according to the object it is supposed to show, and to customize its appearance or behavior. The example below shows a possible implementation for table view cells, but the same process can also be used for collection view.

// MyCellConfigurator.h
#import "JVRCellConfiguratorDelegate.h"

@interface MyCellConfigurator : NSObject<JVRCellConfiguratorDelegate>
@end

// MyCellConfigurator.m
@implementation MyCellConfigurator

- (NSString *)fetchCellIdentifierForObject:(id)anObject
{
    if ([anObject isKindOfClass:[MyClass class]])
    {
        return @"myCell";
    }

    return @"regularCell";
}

- (UITableViewCell *)configureCell:(MyCell *)cell usingObject:(MyClass *)object
{
    cell.titleLabel.text = object.stringProperty;
    return cell;
}

@end

Installation

If you are using JVRCollectionViewDataSource or JVRBaseTableViewDataSource with CocoaPods, JVRCellConfiguratorDelegate is also downloaded as a dependency. You can include it separately by adding the source files to your project or adding the project to your Podfile:

pod 'JVRCellConfiguratorDelegate'
