Is it possible to call editActionsForRowAt of UITableview manually? - ios

Question

In my project, there is a requirement to call editActionsForRowAt of a UITableView on a button action. So that on clicking that button, tableview swipes left.
My editActionsForRowAt code:
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let editAction = UITableViewRowAction(style: .normal, title: "Edit".localized) {[weak self] (rowAction, indexPath) in
// Perform edit action here
}
let deleteAction = UITableViewRowAction(style: .normal, title: "Delete".localized) {[weak self] (rowAction, indexPath) in
// Perform delete action here
}
return [deleteAction,editAction]
}
I do not know whether it is possible or not? I have searched a lot but did not find any solution. Please suggest is it possible or not? If yes, then how to achieve this?

class YourViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, CustomCellDelegate {
#IBOutlet weak var tableView: UITableView?
override func viewDidLoad() {
super.viewDidLoad()
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 2
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "identifier") as? CustomCell else {
return UITableViewCell()
}
cell.indexPath = indexPath
cell.delegate = self
return cell
}
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
return nil
}
func delete(for cell: CustomCell) {
let indexPath = cell.indexPath
print("doing action for cell at: \(indexPath!.row)")
// your implementation for action
// maybe delete a cell or whatever?
cell.hideDeleteActions()
}
}
protocol CustomCellDelegate: class {
func delete(for cell: CustomCell)
}
class CustomCell: UITableViewCell {
weak var delegate: CustomCellDelegate?
var indexPath: IndexPath!
#IBOutlet weak var buttonAction: UIButton?
#IBOutlet weak var constBtnDeleteAction: NSLayoutConstraint?
override func awakeFromNib() {
self.constBtnDeleteAction?.constant = 0
}
override func touchesEnded(_ touches: Set<UITouch>,
with event: UIEvent?) {
guard let point = touches.first?.location(in: self) else {
return
}
if self.point(inside: point, with: event) {
self.showDeleteActions()
}
}
func showDeleteActions() {
self.constBtnDeleteAction?.constant = 100
// Set it according to the button width
UIView.animate(withDuration: 0.3) {
self.layoutIfNeeded()
}
}
func hideDeleteActions() {
self.constBtnDeleteAction?.constant = 0
UIView.animate(withDuration: 0.3) {
self.layoutIfNeeded()
}
}
#IBAction func cellButtonAction() {
delegate?.delete(for: self)
}
}
You need to do more with storyboard like setting constraints of button which will be at the rightmost in the cell and join the outlets.

I think it is possible by call your tableview's delegate method as below
#IBAction func editingstylecalled(_ sender:UIButton)
{
let tag = sender.tag
self.tableView(self.tableview, commit: .delete, forRowAt: IndexPath.init(row: tag, section: 0))
}
Please set your tableview in above code and check.
