table view inside table view in swift4 - ios

Question

I tried tableview inside tableview, sub tableview contains drop down of 4 fields and if click on sub table view row then it will hide and shown in the dropdown button. pls check my below code.
import UIKit
var empname = ["Alex","Henry","Smith","Carey","Stephen"]
var insideArr = ["Retired", "Newly Joined", "Resigned", "Closed" ]
class EmpViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView.tag == 100{
return empname.count
}
else{
return insideArr.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if tableView.tag == 100{
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! DataCell
cell.emp.text = empname[indexPath.item] as? String
cell.btndropdown.tag = indexPath.row
cell.btndropdown.addTarget(self, action: #selector(self.btndrop(sender:)), for: UIControl.Event.touchUpInside)
cell.btndropdown.setTitle("Open", for: .normal)
return cell
}
else{
let cell = tableView.dequeueReusableCell(withIdentifier: "InnerDataCell", for: indexPath) as! InnerDataCell
cell.role.text = insideArr[indexPath.item] as? String
return cell
}
}
#objc func btndrop(sender: UIButton!){
if(sender.isSelected == true){
sender.isSelected = false
}
else{
sender.isSelected = true
}
}
}
class InnerDataCell: UITableViewCell {
#IBOutlet weak var lblInsideName: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
class DataCell: UITableViewCell {
#IBOutlet weak var tblInsideTableView: UITableView!
#IBOutlet weak var sitename: UILabel!
#IBOutlet weak var btndropdown: UIButton!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
extension DataCell{
func setTableViewDataSourceDelegate
<D:UITableViewDelegate & UITableViewDataSource>
(_ dataSourceDelegate: D, forRow row: Int){
tblInsideTableView.delegate = dataSourceDelegate
tblInsideTableView.dataSource = dataSourceDelegate
tblInsideTableView.reloadData()
}
}
Required output:
Emp1 select V
Emp2 select V
if click on Select button in 1st index, then
Emp1 Select V
Emp2 Select V
Retired
Newly Joined
Resigned
Closed
if click on closed option then it will be
Emp1 Select V
Emp2 Closed V
