快速禁用表格视图单元格中的滑动操作

Question

I have implemented the swipe action for the table view cell and they are two actions: Accept and Reject .

When I swipe for the first time it must appear and for the second time if I swipe the cell it should not open.

The swipe action for the cell must be in the disabled mode.

Answer 1

First, you should keep track of the indexPath of cells you have interacted with.

private var disabledCellsIndexPath = [IndexPath]()

Then in the method to configure your swipe actions ( this is the new iOS 11 API ):

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {

    let action = UIContextualAction(style: .normal, title: "Action Title", handler: { _, _, completionHandler in

        // DO WHAT YOU WANT HERE
        // …

        // This is where you specify that this specific cell should be 'disabled'
        self?.disabledCellsIndexPath.append(indexPath)

        completionHandler(true)
    })

    return UISwipeActionsConfiguration(actions: [action])
}

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return !disabledCellsIndexPath.contains(indexPath)
}

Answer 2

If I understood your question correctly, Please follow following generalize idea,

You can manage the flag ?for that indexPath? in app end database. Whenever required open or disable ie manage it you can enable/disable the edit action for that indexPath.

Answer 3

Use allowEdit flag when you want swipe Enable . else make it false.

var allowEdit: Bool = true
    func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
        return allowEdit
    }



     func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]?
        {
           if allowEdit{
               /*to perform Accept and Reject action on row*/
           }
    }
