using indexPath from table row in outside function swift - ios

Question

New to swift and for a uni project but i have a table view which holds a record of friends details
The user can have the option to edit a friend or delete a friend.
to do this i created a long tap gesture for delete a friend but i am unsure how to pass the indexPath to the function
this is my current layout:
import UIKit
class view_19342665: UIViewController,UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
var friends: [Friends] = []
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return friends.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "friends", for: indexPath)
cell.textLabel?.adjustsFontSizeToFitWidth = true;
cell.textLabel?.font = UIFont.systemFont(ofSize: 13.0)
cell.textLabel?.text = friends[indexPath.row].displayInfo
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let id = friends[indexPath.row].studentID
let appDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.removeRecord(id: Int(id))
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
tableView.delegate = self
tableView.dataSource = self
let appDelegate = UIApplication.shared.delegate as! AppDelegate
friends = appDelegate.getFriendInfo()
let longPress = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress(sender:)))
tableView.addGestureRecognizer(longPress)
self.tableView.rowHeight = 33.0
}
override var canBecomeFirstResponder: Bool{
return true
}
#objc func handleLongPress(sender:UILongPressGestureRecognizer ){
if sender.state == .began{
// delete user
}
else{
//edit user
}
}
}
right now i can delete the row in the table function.
this is what i am trying to achieve:
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let id = friends[indexPath.row].studentID
handleLongPress(id)
}
func handleLongPress(id : Int){
let appDelegate = UIApplication.shared.delegate as! AppDelegate
if sender.state == .began{
appDelegate.removeRecord(id: Int(id))
}
else{
appDelegate.editRecord(id: Int(id))
}
can someone please help me delete a row using the ID on a long tap gesture

Answer 1

The gesture should be added to the table cells inside cellForRowAt not to the table itself
let longPress = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress(_:)))
cell.contentView.addGestureRecognizer(longPress)
cell.contentView.tag = indexPath.row
Then
#objc func handleLongPress(_ tap:UILongPressGestureRecognizer) {
guard tap.state == .ended && let index = tap.view?.tag else { return }
// use index
}
