Slide Out Bar with sub categories in swift - ios

Question

There are some rows in table view. Each row opens a new view. Now I want to show some sub categories on click of Particular row. each of this sub category opens different view. I am using only 1 section. Any ideas?

Answer 1

Simply do this.
class CategoriesListViewController: UIViewController {
#IBOutlet weak var tableView: UITableView!
var filterCategories = [CategoryViewModel]()
override func viewDidLoad() {
super.viewDidLoad()
tfSearch.placeholder = LocalizeKey.search.localized
getCategories()
// Do any additional setup after loading the view.
}
extension CategoriesListViewController : UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return filterCategories.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CategoryCellTableView
let category = filterCategories[indexPath.row]
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if let controller : SubCategoriesListViewController = ViewControllerManager.shared.find() {
controller.selectedCategory = self.filterCategories[indexPath.row]
self.pushViewController(controller : controller)
}
}
Sub-Categories will be subclassed from the main categories and override the table view selection methods and do whatever you want to do.
class SubCategoriesListViewController: CategoriesListViewController {
#IBOutlet weak var tableView: UITableView!
var filterCategories = [CategoryViewModel]()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let controller = DifferentViewController()
self.pushViewController(controller : controller)
}
