删除具有多个TableView的行

Question

If I have 2-3 TableView, how can I disable 'Delete' row only for the specific TableView? When I set breakpoint for if statement to check which tableView is used, it's not working

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if tableView == self.firstTableView {
        if editingStyle == .delete {
            array.remove(at: indexPath.row)
            firstTableView.deleteRows(at: [indexPath], with: .fade)
            firstTableView.reloadData()
        }
    }
}

I tried to set editing mode to false in viewDidLoad for secondTableView but it's not working also.

secondTableView.setEditing(false, animated: false)

I understand that by default it's set to false, so I thought if commit editingStyle enable it for all tableViews, so I can disable it for second.

Answer 1

Just give each TableView a tag and check it in an if or switch statement.

if tableView.tag == 0 {
    if editingStyle == .delete {
        array.remove(at: indexPath.row)
        tableView.deleteRows(at: [indexPath], with: .fade)
        tableView.reloadData()
    }
}

Answer 2

The correct answer is checking for tag in editingStyleForRowAt indexPath

 func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCellEditingStyle {
    if tableView.tag == 1 {
        return UITableViewCellEditingStyle.delete
    } else {
        return UITableViewCellEditingStyle.none
    }

}

You can use:

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {

        // Return false if you do not want the specified item  or table to be editable.
        if tableView == tableVw {
            return false
        } else {
            return true
        }
  }

Here tableVw is a tableview object which you want to not editable or you can also use tag instead of object compare. Then use:

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
        if editingStyle == .delete {

           //Write your delete cell logic here
           array.remove(at: indexPath.row)
           tableView.deleteRows(at: [indexPath], with: .fade)
           tableView.reloadData()
         }
}
