Can't disable editing on table after deleting a row - swift

Question

In my table view, after I delete a record, I want it to disable editing if the last record was deleted, but even after calling setEditing the state doesn't change. Here's a simplified example that still shows the behavior:
class TestViewController: UITableViewController {
var items = [String]()
override func viewDidLoad() {
super.viewDidLoad()
self.navigationItem.rightBarButtonItems = [
UIBarButtonItem(title: "Add", style: .plain, target: self, action: #selector(add)),
UIBarButtonItem(title: "Remove", style: .plain, target: self, action: #selector(remove))
]
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.items.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell()
cell.textLabel?.text = self.items[indexPath.row]
return cell
}
override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
self.items.remove(at: indexPath.row)
if self.items.count == 0 {
// This is getting executed, but not changing the table's state
self.tableView.setEditing(false, animated: false)
}
self.tableView.reloadData()
}
#objc func add () {
self.items.append("foo")
self.tableView.reloadData()
}
#objc func remove () {
self.tableView.setEditing(!self.tableView.isEditing, animated: true)
}
}
Clicking the "Remove" button toggles editing on and off without any problems, but if I delete the last one and then add a new one, it still shows up in editing mode. I tried stepping through the code, and it's definitely hitting the correct line, but even after executing it tableView.isEditing is still true. What am I doing wrong here?

Answer 1

I have checked your code, as per Hikaru Watanabe's comment , it is not working.
So i have made change in commit editingstyle method and it is working fine,
please check below code
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
self.items.remove(at: indexPath.row)
self.tableView.deleteRows(at: [indexPath], with: .left)
if self.items.count == 0 {
// This is getting executed, but not changing the table's state
self.tableView.setEditing(false, animated: false)
}
//self.tableView.reloadData()
}
Updated After John's Comment -
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
self.items.remove(at: indexPath.row)
if self.items.count == 0 {
// This is getting executed, but not changing the table's state
self.tableView.deleteRows(at: [indexPath], with: .none)
self.tableView.setEditing(false, animated: false)
}else{
self.tableView.reloadData()
}
}

You should use this method:
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return editingEnable
}
Just set true or false this variable "editingEnable" on your condition.
