// Let SomeModel adopts and conforms to the ModelType protocol
struct SomeModel: ModelType {
let someA: [A]
let someB: [B]
let someC: [C]
let someD: [D]
var data: [[Any]] {
return [someA, someB, someC, someD]
}
}
extension SomeModel {
static var tCells: [UITableViewCell.Type]? {
// All cell types created by pure code.
[ACell.self, BCell.self]
}
static var tNibs: [UITableViewCell.Type]? {
// All cell types created by nib.
[CCell.self, DCell.self]
}
static var tAll: [UITableViewCell.Type]? {
// All cell types, Sort by display order.
[ACell.self, BCell.self, CCell.self, DCell.self]
}
}In SomeCell.swift:
class SomeCell: UITableViewCell {
...
// Configure cell
override func configure(_ model: Any?) {
...
}
}In SomeViewController.swift:
import YLExtensions
// 1. Create a model object
let someModel = SomeModel(...)
// 2. Register cells
override func viewDidLoad() {
super.viewDidLoad()
...
tableView.registerCells(with: SomeModel.tCells!)
tableView.registerNibs(with: SomeModel.tNibs!)
}
// 3. Create and configure cells
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Note: Only applies when cells of the same type are all together and the different types of cells are in different section.
let cell = tableView.dequeueReusableCell(for: indexPath, with: SomeModel.tAll!)
cell.configure(someModel.data[indexPath.section][indexPath.row])
return cell
