Why does UITableView show the same view for each cell? - swift

Question

I have been trying to implement a UISegmentedControl in the first cell of a UITableView and it has worked however it shows for each cell following the first one. How do I fix this
import UIKit
class InfoTableViewController: UITableViewController {
convenience init() {
self.init(style: UITableView.Style.grouped)
}
var image: UIImage?
override func viewDidLoad() {
super.viewDidLoad()
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 5
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 1
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// let cell = tableView.dequeueReusableCell(withIdentifier: "myCell", for: indexPath)
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath as IndexPath)
if indexPath.row == 0 {
let genderItems = ["Male", "Female"]
let genderControl = UISegmentedControl(items: genderItems)
genderControl.addTarget(self, action: #selector(genderChanged), for: .valueChanged)
cell.contentView.addSubview(genderControl)
genderControl.translatesAutoresizingMaskIntoConstraints = false
genderControl.centerXAnchor.constraint(equalTo: cell.centerXAnchor).isActive = true
genderControl.centerYAnchor.constraint(equalTo: cell.centerYAnchor).isActive = true
}
return cell
}
override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
if section == 0{
return view.frame.height/3
}
return UITableView.automaticDimension
}
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
if section == 0 {
let imageView: UIImageView = UIImageView()
imageView.clipsToBounds = true
imageView.contentMode = .scaleAspectFit
imageView.image = self.image
return imageView
}
return nil
}
#objc func genderChanged(){
}
}

Answer 1

Solution #1
Remove this
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 5
}
and return 5 here
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 5
}
Solution #2
Replace
if indexPath.row == 0 {
to
if indexPath.section == 0 {
in both options you should implement else for that if to return the other needed cell
also move this line to viewDidLoad
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")
