Set table view to edit mode

Question

I have UITableViewin UIViewControllerand added an edit button from the code, not IB. This happens to UITableViewControllers, but not to, the UIVC. How can I get this button to quickly put the table view into edit mode? Thanks in advance for any help.

class WordsViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, UITextFieldDelegate  {
  override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.rightBarButtonItem = self.editButtonItem()
  }

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

Answer 1

Create rightBarButtonItem, as shown below, with the action.

In viewDidLoad():

let rightButton = UIBarButtonItem(title: "Edit", style: UIBarButtonItemStyle.Plain, target: self, action: Selector("showEditing:"))
    self.navigationItem.rightBarButtonItem = rightButton

and then make a function like,

 func showEditing(sender: UIBarButtonItem)
 {
    if(self.tableView.isEditing == true)
    {
        self.tableView.isEditing = false
        self.navigationItem.rightBarButtonItem?.title = "Done"   
    }
    else
    {
        self.tableView.isEditing = true
        self.navigationItem.rightBarButtonItem?.title = "Edit" 
    }
}

Be sure :to add to the function name in the Selectoractions in viewDidLoad
Hope this helps!

Swift 3 4 , IMHO , :

override func viewDidLoad() {
    super.viewDidLoad()

    let editButton = UIBarButtonItem(title: "Edit", style: .plain, target: self, action: #selector(toggleEditing)) // create a bat button
    navigationItem.rightBarButtonItem = editButton // assign button
}

@objc private func toggleEditing() {
    listTableView.setEditing(!listTableView.isEditing, animated: true) // Set opposite value of current editing status
    navigationItem.rightBarButtonItem?.title = listTableView.isEditing ? "Done" : "Edit" // Set title depending on the editing status
}

• "Bar" , , .

Swift 4.2:

override func viewDidLoad() {
  super.viewDidLoad()

  // Use the edit button provided by the view controller.
  navigationItem.rightBarButtonItem = editButtonItem
}

override func setEditing(_ editing: Bool, animated: Bool) {
    // Takes care of toggling the button title.
    super.setEditing(!isEditing, animated: true)

    // Toggle table view editing.
    tableView.setEditing(!tableView.isEditing, animated: true)
}

setEditing editButtonItem. "" "", super.setEditing , tableView setEditing ..
