Table cells in the second view are not displayed - ios

Question

The table cells contained in the first view are properly represented, but the table cells contained in the second view do not appear. I can’t understand why.
HelpController.swift
import UIKit
class HelpController: UIViewController, UITableViewDelegate, UITableViewDataSource {
// MARK: - Initialize
#IBOutlet weak var menuTable: UITableView!
let helpMenu = ["a","b","c"]
override func viewDidLoad() {
super.viewDidLoad()
//datasource link
menuTable.delegate = self
menuTable.dataSource = self
self.menuTable?.tableFooterView = UIView()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
// MARK: - Table View Data Source
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return helpMenu.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.subtitle, reuseIdentifier: "HelpMenuCell")
cell.textLabel?.text = helpMenu[indexPath.row]
return cell
}
}
When i check it with print (helpmenu.count), it return 3. It seems to work well until numberOfRowsInSection, but cellForRowAt does not work.
and this is my first view InfosController.swift
// MARK: - Table View Data Source
// get cell count
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if UserDefaults.standard.value(forKey: "userid") != nil {
// sign in state
return memberMenu.count
} else {
// sign out state
return nonMemberMenu.count
}
}
// change cell text
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.subtitle, reuseIdentifier: "InfosMenuCell")
if UserDefaults.standard.value(forKey: "userid") != nil {
// sign in state
cell.textLabel?.text = memberMenu[indexPath.row]
} else {
// sign out state
cell.textLabel?.text = nonMemberMenu[indexPath.row]
}
return cell
}
This is the code included in the first view that works properly. This works well, but I’m confused because it does not work well in the second view(HelpController).
ps.

Answer 1

The problem in HelpController, In controlle self.menuTable?.tableFooterView = UIView()
So if You are having footer view then You need to write the delegate function heightForFooterInSection and viewForFooterInSection
func tableView(tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
}
func tableView(tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
}

Answer 2

Make sure below things
Make sure you added Delegate & DataSource to tableView.
Check your helpMenu count is not equal to
Zero.
If numberOfRowsInSection returns Zero, then probably cellForRowAt
indexPath won't call.
Please check the method declaration once the correct syntax is
func tableView(_ tableView: UITableView, cellForRowAt indexPath:
IndexPath) -> UITableViewCell { }
