How can I get indexPath.row in cell.swift

Question

I have 2 files.

• myTableViewController.swift
• myTableCell.swift

Can I get the indexPath.row in myTabelCell.swift function?

Here is myTableCell.swift

import UIKit import Parse import ActiveLabel  class myTableCell : UITableViewCell {      //Button     @IBOutlet weak var commentBtn: UIButton!     @IBOutlet weak var likeBtn: UIButton!     @IBOutlet weak var moreBtn: UIButton!       override func awakeFromNib() {         super.awakeFromNib()       }      @IBAction func likeBtnTapped(_ sender: AnyObject) {          //declare title of button         let title = sender.title(for: UIControlState())          //I want get indexPath.row in here!      } 

Here is myTableViewController.swift

class myTableViewController: UITableViewController {      //Default func     override func viewDidLoad() {         super.viewDidLoad()          //automatic row height         tableView.estimatedRowHeight = 450         tableView.rowHeight = UITableViewAutomaticDimension        }   // cell config     override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {           //define cell         let cell = tableView.dequeueReusableCell(withIdentifier: "myTableCell", for: indexPath) as! myTableCell     } 

As you can see... I'm trying to get indexPath.row in myTableCell, liktBtnTapped function.

Could you let me know how can I access or get IndexPath.row?

I have created a UIResponder extension with a recursive method that you can use in any UIView (which inherits from UIResponder) to find a parent view of a specific type.

import UIKit  extension UIResponder {     /**      * Returns the next responder in the responder chain cast to the given type, or      * if nil, recurses the chain until the next responder is nil or castable.      */     func next<U: UIResponder>(of type: U.Type = U.self) -> U? {         return self.next.flatMap({ $0 as? U ?? $0.next() })     } } 

Using this, we can extend UITableViewCell with some convenient read-only computed properties for the table view and index path of the cell.

extension UITableViewCell {     var tableView: UITableView? {         return self.next(of: UITableView.self)     }      var indexPath: IndexPath? {         return self.tableView?.indexPath(for: self)     } } 

Here is how you could use it in your example:

@IBAction func likeBtnTapped(_ sender: AnyObject) {     //declare title of button     let title = sender.title(for: UIControlState())      //I want get indexPath.row in here!     self.indexPath.flatMap { print($0) } }

Try this inside your cell.

func getIndexPath() -> IndexPath? {     guard let superView = self.superview as? UITableView else {         print("superview is not a UITableView - getIndexPath")         return nil     }     indexPath = superView.indexPath(for: self)     return indexPath }
