Unsure what’s flawed, I really feel like I’ve accomplished this a thousand occasions through the years, however its not working this time.
I’ve a UIViewController (not UITableViewController) and I create a UITableView in loadView(). I set the delegate and the datasource. I implement the canMoveRowAt and the moveRowAt delegate strategies. I add a UIBarButtonItem to faucet to place the desk into edit mode however not one of the reorder controls present up.
class MyTableViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var tableview: UITableView!
override func loadView() {
// deliberately not calling tremendous
self.tableview = UITableView(body: .zero, model: .grouped)
self.tableview.delegate = self
self.tableview.dataSource = self
self.view = self.tableview
}
override func viewDidLoad() {
tremendous.viewDidLoad()
self.tableview.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
let reorderbutton = UIBarButtonItem(picture: UIImage(systemName: "mount"), model: .plain, goal: self, motion: #selector(tappedreorder(_:)))
self.navigationItem.rightBarButtonItems = [reorderbutton]
}
@objc func tappedreorder(_ sender:Any) {
self.tableview.setEditing(true, animated: true)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
var config = cell.defaultContentConfiguration()
config.textual content = ...
cell.contentConfiguration = config
return cell
}
func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {
print("moved row from (sourceIndexPath) to (destinationIndexPath)")
}
func tableView(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool {
print("can transfer row at (indexPath), true")
return true
}
}
Once I set the desk into modifying mode, I do not get any calls backs to canMoveRowAt and not one of the rows present the reorder controls.
I’ve additionally tried including cell.showsReorderControl = self.tableview.isEditing to the cellForRowAt implementation in order that it explicitly requests the transfer management, however that did not change something as a result of not one of the rows have been really being reloaded. Even once I set the desk into edit mode after which did a reloadData() to reload all of the rows and set cell.showsReorderControl, they nonetheless did not present up.
