如何在TableView单元格中创建长按键进行分割

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    @IBOutlet weak var tableView: UITableView!
    var data = ["Cell 1", "Cell 2", "Cell 3", "Cell 4"]

    override func viewDidLoad() {
        super.viewDidLoad()
        
        let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress(_:)))
        tableView.addGestureRecognizer(longPressGesture)
    }

    @objc func handleLongPress(_ gestureRecognizer: UILongPressGestureRecognizer) {
        if gestureRecognizer.state == .began {
            let touchPoint = gestureRecognizer.location(in: tableView)
            if let indexPath = tableView.indexPathForRow(at: touchPoint) {
                showSplitOptions(for: indexPath)
            }
        }
    }

    func showSplitOptions(for indexPath: IndexPath) {
        let alertController = UIAlertController(title: "Split Options", message: nil, preferredStyle: .actionSheet)
        
        let splitAboveAction = UIAlertAction(title: "Split Above", style: .default) { _ in
            self.splitCell(at: indexPath, above: true)
        }
        alertController.addAction(splitAboveAction)
        
        let splitBelowAction = UIAlertAction(title: "Split Below", style: .default) { _ in
            self.splitCell(at: indexPath, above: false)
        }
        alertController.addAction(splitBelowAction)
        
        let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
        alertController.addAction(cancelAction)
        
        present(alertController, animated: true, completion: nil)
    }
    
    func splitCell(at indexPath: IndexPath, above: Bool) {
        let newData = "New Cell"
        if above {
            data.insert(newData, at: indexPath.row)
        } else {
            data.insert(newData, at: indexPath.row + 1)
        }
        tableView.reloadData()
    }

    // TableView DataSource and Delegate methods
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return data.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
        cell.textLabel?.text = data[indexPath.row]
        return cell
    }
}
