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.
