I've a custom UITableViewCell, in that I've two UILabels & one UIButton. I'm able to load data...and display it as per requirement.

• Problem Statement-1: Now problem exist in my UIButton, which is in my UICustomTableViewCell. Due to this I'm unable to handle click event on that UIButton.




• Problem Statement-2: On button Click I have to identify the index of that Button click and pass data to next ViewController using segue.

Now have a look on...what did I've tried for this...

Yes, first-of-all I have thought that Binding IBOutlet action in my CustomCell will resolve my problem...but actually it doesn't solved my problem.

After that I've accessed button using .tag and initialised index path.row to it.

But it won't helped me.

So now I'm using Protocol oriented concept using delegate to handle click event on my UIButton which is available in CustomCell.

What did I tried:

SwiftyTableViewCellDelegate:

protocol SwiftyTableViewCellDelegate : class {

    func btnAuditTrailDidTapButton(_ sender: LeadCustomTableViewCell)

}

  CustomTableViewCell with delegate:

  
  
  

  class LeadCustomTableViewCell: UITableViewCell {
  
  
  
      @IBOutlet weak var lblMeetingPersonName: UILabel!
  
      @IBOutlet weak var lblPolicyNo: UILabel!
  
      @IBOutlet weak var btnLeadAuditTrail: UIButton!
  
  
  
  
  
      weak var delegate: SwiftyTableViewCellDelegate?
  
  
  
      override func setSelected(_ selected: Bool, animated: Bool) {
  
          super.setSelected(selected, animated: animated)
  
      }
  
  
  
      @IBAction func btnAuditTrailTapped(_ sender: UIButton) {
  
          delegate?.btnAuditTrailDidTapButton(self)
  
      }
  
  }

  ViewController implementing delegate:

  
  
  

  class LeadViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, SwiftyTableViewCellDelegate {
  
  
  
      //IBOutlet Connections - for UITableView
  
      @IBOutlet weak var tableView: UITableView!
  
  
  
      override func viewDidLoad() {
  
          super.viewDidLoad()
  
  
  
          //setting dataSource & delegates of UITableView with this ViewController
  
          self.tableView.dataSource = self
  
          self.tableView.delegate = self
  
  
  
          //Reloading tableview with updated data
  
          self.tableView.reloadData()
  
  
  
          //Removing extra empty cells from UITableView
  
          self.tableView.tableFooterView = UIView()
  
      }
  
  
  
      func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
  
  
  
          let cell:LeadCustomTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: "cell") as! LeadCustomTableViewCell
  
  
  
          //Assigning respective array to its associated label
  
          cell.lblMeetingPersonName.text = (meetingPersonNameArray[indexPath.section] )
  
          cell.lblPolicyNo.text = (String(policyNoArray[indexPath.section]))
  
  
  
          cell.btnLeadAuditTrail.tag = indexPath.section
  
          cell.delegate = self
  
  
  
          return cell
  
      }
  
  
  
      //This is delegate function to handle buttonClick event
  
  
  
      func btnAuditTrailDidTapButton(_ sender: LeadCustomTableViewCell) {
  
          guard let tappedIndexPath = tableView.indexPath(for: sender) else { return }
  
          print("AuditTrailButtonClick", sender, tappedIndexPath)
  
      } 
  
  

  
  
  

  Don't know why this is not working.

  
  

Link the touch up inside event in cellForRow by adding the following code:

cell.btnLeadAuditTrail.addTarget(self, action:#selector(btnAuditTrailDidTapButton(_:)), for: .touchUpInside)
