Usage

View / ViewController usage concept

Instantiation

Views and ViewControllers should be instantiated using the instantiate(bundle:, withOwner:, options:) extension on UIView and UIViewController, it will lookup for a nib file with the same name as the custom view class in the bundle and instantiate it or if there is no nib available the default initializer will be used for instantiation.

Specializations

Every view with dynamic content should subclass from StatefulView with a specific ViewModel.

Example:

final class ExampleView: StatefulView<ExampleViewModel> {
    override func viewDidLoad() {
        super.viewDidLoad()

        // Load custom child views here or run initial setup code ...
    }

    override func didChangeModel() {
        super.didChangeModel()

        // Update view content using model here ...
        print(model.title)
    }
}

struct ExampleViewModel: ViewModelProtocol {
    let title: String

    init(
        title: String = ExampleViewModel.default.title
    ) {
        self.title = title
    }
}

extension ExampleViewModel {
    static let `default`: ExampleViewModel = .init(
        title: ""
    )
}

TableView / CollectionView usage

Every StatefulView can also be used inside a UITableView or in a UICollectionView as cell by creating a cell specialization.

Example:

final class ExampleTableViewCell: ContainerTableViewCell<ExampleView> {}

final class ExampleCollectionViewCell: ContainerCollectionViewCell<ExampleView> {}

final class MyTableViewController: UITableViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        tableView.register(cellOfType: ExampleTableViewCell.self)
    }
    
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeue(cellOfType: ExampleTableViewCell.self, for: indexPath)
        cell.model = ExampleViewModel(title: "Hello World")
        return cell
    }
}
