Create UITableView with multiple Custom Cells in Swift - json

Question

What is the best current way to create an UITableView with multiples Custom Cell with the storyboard and the tableView methods?
For now, I get correctly my JSON response split into 3 arrays then I want to use it to update my tableView with 3 different custom cells.
class MainViewController: UIViewController {
// MARK: - Properties
var starters = [Starter]()
var dishes = [Dish]()
var deserts = [Desert]()
// MARK: - Outlets
#IBOutlet weak var foodTableView: UITableView!
// MARK: - Functions
func updatDisplay() {
ApiHelper.getFoods { starters, dishes, deserts in
self.starters = starters
self.dishes = dishes
self.deserts = deserts
self.foodTableView.reloadData()
}
}
// MARK: - View Lifecycle
override func viewDidLoad() {
super.viewDidLoad()
updatDisplay()
}
}
extension MainViewController: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "StarterCell", for: indexPath)
return cell
}
}

Answer 1

Assuming that you have the three sections "starters", "dishes" and "deserts" you can display the cells like this:
override func numberOfSections(in tableView: UITableView) -> Int {
return 3
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0 {
return starters.count
}
else if section == 1 {
return dishes.count
}
else {
return deserts.count
}
}
override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
if section == 0 {
return "Starters"
}
else if section == 1 {
return "Dishes"
}
else {
return "Deserts"
}
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
return tableView.dequeueReusableCell(withIdentifier: "StarterCell", for: indexPath)
}
else if indexPath.section == 1 {
return tableView.dequeueReusableCell(withIdentifier: "DishesCell", for: indexPath)
}
else {
return tableView.dequeueReusableCell(withIdentifier: "DesertsCell", for: indexPath)
}
}
