Not work UITableView in cellForRowAt But numberOfRowsInsection Work in Swift - ios

Question

I wrote a function to add a Cell in a UITableView.
numberOfRowsInSection works but cellForRowAt does not work.
class ShopMenuViewCell: UITableViewCell {
#IBOutlet weak var menuTableView: UITableView!
var menuPrice: MenuPrice!
override func awakeFromNib()
{
super.awakeFromNib()
}
}
extension ShopMenuViewCell
{
func setView()
{
self.menuTableView.delegate = self
self.menuTableView.dataSource = self
self.menuTableView.regCells(cells: ["ShopMenuInformationCell"])
DispatchQueue.main.async
{
self.menuTableView.reloadData()
}
}
}
extension ShopMenuViewCell : UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "ShopMenuInformationCell", for: indexPath) as? ShopMenuInformationCell,
let menu = self.menuPrice,
let name = menu.name,
let price = menu.amt else { return ShopMenuInformationCell() }
return cell
}
}
In ShpMenuInformationCell.swift
class ShopMenuInformationCell: UITableViewCell
{
#IBOutlet weak var containerView: UIView!
#IBOutlet weak var shopNameLabel: UILabel!
#IBOutlet weak var menuNameLabel: UILabel!
#IBOutlet weak var priceLabel: UILabel!
override func awakeFromNib()
{
super.awakeFromNib()
}
}
I saw the answer to add a ViewController, but I do not know what to do because it is not a storyboard. (.xib)
I think it is because I add UITableViewCell in the UITableViewCell class.
Do you know why?

Answer 1

I had a problem for about 5 days and found a solution!
First Reference Site: Joel's Answer cellForRowAtIndexPath: not called
Second reference site: Paolo's answer
Swift: UITableViewCell rowheight
When I add another kind of TableCell, the vertical size of the cell in question is small.
So I increased the size of the Cell's RowHeight (frame.height) before reloading the data and it's fixed!
Currently, cellforrowat runs safely. Your answers were helpful to the results.

Please try below code:
class ShopMenuViewCell: UITableViewCell
{
#IBOutlet weak var menuTableView: UITableView!
var menuPrice: MenuPrice!
override func awakeFromNib()
{
super.awakeFromNib()
}
fun setUpTable() {
self.menuTableView.regCells(cells: ["ShopMenuInformationCell"])
self.menuTableView.delegate = self
self.menuTableView.dataSource = self
self.menuTableView.reloadData()
}
}
and call the function setUpTable() from ShopMenuViewCell as an cell.setUpTable()
