A wrapper for UI elements that dequeue cells. Cells are dequeued by their corresponding type.

Usage

This is a full implementation that assumes you are not using interface building.

import UIKit
import Dequeue

final class TableViewCell: UITableViewCell, DequeableComponentIdentifiable {}

final class TableView: UITableView, DequeableTableView {}

final class ViewController: UIViewController, UITableViewDataSource {
    
    private let tableView = TableView()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        view.addSubview(tableView)
        tableView.register(cellType: TableViewCell.self, hasXib: false)
        tableView.dataSource = self
    }
    
    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        tableView.frame = view.bounds
    }
    
    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 10
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        guard let tableView = tableView as? DequeableTableView else { 
            fatalError("Ooops. Missed a step.")
        }
        return cell(in: tableView, at: indexPath)
    }
    
    private func cell(in tableView: DequeableTableView, at indexPath: IndexPath) -> UITableViewCell {
        let cell: TableViewCell = tableView.dequeueCell(at: indexPath)
        cell.textLabel?.text = "Row \(indexPath.row + 1)"
        return cell
    }
}

Interface Builder

If you are using interface builder, then these addtiional implementation steps are required.

• Make sure your source files and your interface builder files are in the same bundle and have matching names.
• You will need to specify reuse identifiers in your interface builder files, for each cell you build. This should be the classname of the cell subclass, plus ID. For example MyTableViewCellID.
• If you have prepared a cell using a .xib then you will need to pass true here.

tableView.register(cellType: TableViewCell.self, hasXib: true)

N.B. You do not need to register if you are using a storyboard.
