Answer 1

First you create tree cell class with .xib.
#IBAction func btnNewClick(_ sender:UIButton)
{
self.approvedButton.isSelected = false
self.rejectedButton.isSelected = false
self.Yourtbl.reloadData()
}
set action btnapprovedClick button
#IBAction func btnapprovedClick(_ sender:UIButton)
{
self.approvedButton.isSelected = true
self.rejectedButton.isSelected = false
self.newButton.isSelected = false
self.Yourtbl.reloadData()
}
set action btnrejectedClick button
#IBAction func btnrejectedClick(_ sender:UIButton)
{
self.approvedButton.isSelected = false
self.rejectedButton.isSelected = true
self.newButton.isSelected = false
self.Yourtbl.reloadData()
}

Answer 2

Why don't you use enum? See the code below for further reference.
import UIKit
enum ViewType {
case new, approved, rejected
}
class ViewController {
private var viewType: ViewType = .new
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
switch viewType {
case .new :
let cell = self.addNewTblview.dequeueReusableCell(withIdentifier: "AddInstructorNewCell", for: indexPath) as! AddInstructorNewCell
return cell
case .approved:
let cell = self.addNewTblview.dequeueReusableCell(withIdentifier: "ApprovedCell", for: indexPath) as! ApprovedCell
return cell
case .rejected:
let cell = self.addNewTblview.dequeueReusableCell(withIdentifier: "RejectedCell", for: indexPath) as! RejectedCell
return cell
}
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
switch viewType {
case .new:
return 170
case .approved:
return 165
case .rejected:
return 178
}
}
#IBAction func btnNewClick(_ sender:UIButton)
{
viewType = .new
tableView.reloadData()
}
#IBAction func btnapprovedClick(_ sender:UIButton)
{
viewType = .approved
tableView.reloadData()
}
#IBAction func btnrejectedClick(_ sender:UIButton)
{
viewType = .rejected
tableView.reloadData()
}
}
