import JSQDataSourcesKit

Design

This library has four primary components:

1. Section — represents a section of data
2. DataSource — represents a collection of Section types
3. ReusableViewConfig — responsible for dequeuing and configuring cells (for UITableView or UICollectionView)
4. DataSourceProvider — owns a data source and view config, and provides a UICollectionViewDataSource or UITableViewDataSource object.

Example

The following illustrates a simple example of how these components interact for a collection view.

// Given a view controller with a collection view

// 1. create Sections and a DataSource with your model objects
let section0 = Section(items: ...)
let section1 = Section(items: ...)
let section2 = Section(items: ...)
let dataSource = DataSource(sections: section0, section1, section2)

// 2. create cell config
let cellConfig = ReusableViewConfig(reuseIdentifier: "CellId") { (cell, model?, type, collectionView, indexPath) -> MyCellClass in
    // configure the cell with the model
    return cell
}

// 3. create supplementary view config
let type = ReusableViewType.supplementaryView(kind: UICollectionElementKindSectionHeader)
let headerConfig = ReusableViewConfig(reuseIdentifier: "HeaderId", type: type) { (view, model?, type, collectionView, indexPath) -> MyHeaderView in
    // configure header view
    return view
}

// 4. create data source provider
let dataSourceProvider =  DataSourceProvider(dataSource: dataSource,
                                             cellConfig: cellConfig,
                                             supplementaryConfig: headerConfig)

// 5. set the collection view's data source
collectionView.dataSource = dataSourceProvider.collectionViewDataSource
