Simple view controller that provides a way to configure a table view with multiple types of cells while keeping type safety. To learn what and whys I encourage you to read the associated blog post.
Let's say we want to present a table view controller with four rows: two with text and two with images. We start by creating view data structures that cells will be configurable with:
struct TextCellViewData { let title: String } struct ImageCellViewData { let image: UIImage }
and the cells themselves:
class TextTableViewCell: UITableViewCell { func updateWithViewData(viewData: TextCellViewData) { textLabel?.text = viewData.title } } class ImageTableViewCell: UITableViewCell { func updateWithViewData(viewData: ImageCellViewData) { imageView?.image = viewData.image } }
Now to present a table view controller with those cells, we simply configure it in the following way:
import ConfigurableTableViewController ... let viewController = ConfigurableTableViewController(items: [ CellConfigurator<TextTableViewCell>(viewData: TextCellViewData(title: "Foo")), CellConfigurator<ImageTableViewCell>(viewData: ImageCellViewData(image: apple)), CellConfigurator<ImageTableViewCell>(viewData: ImageCellViewData(image: google)), CellConfigurator<TextTableViewCell>(viewData: TextCellViewData(title: "Bar")), ]) presentViewController(viewController, animated: true, completion: nil)
And ta-da 🎈:
I encourage you to check both the implementation and an example app.
To run the example project; clone the repo, open the project and run ExampleApp target.
iOS 8 and above.
