how to subclass UITableView to use in other viewControllers - ios

Question

I'm looking to create a subclass for a tableview that I would like to use throughout out all my app. My problem is when I set the fields variable the tableview is still empty. I'm assuming that the fields variable is not setting right when it is set in the new ViewController. Thank you for the help in advance.
MySubClass
import UIKit
import LGButton
class RquestTableViewController: UITableViewController {
var fields:[UIView]
override func viewDidLoad() {
super.viewDidLoad()
viewSetup()
}
func viewSetup(){
tableView.register(CustomFormCell.self, forCellReuseIdentifier: labelReuseCellIdentifier)
self.tableView.tableFooterView = UIView.init(frame: CGRect.zero)
}
}
//MARK: Delegate
extension RquestTableViewController {
override func numberOfSections(in tableView: UITableView) -> Int {
return fields.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: self.labelReuseCellIdentifier, for: indexPath) as! CustomFormCell
let itemView = fields[indexPath.row]
cell.viewPassed = itemView
cell.backgroundColor = .clear
if let _ = itemView as? UILabel {
cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0)
return cell
}
if let _ = itemView as? UIButton {
cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0)
return cell
}
if let _ = itemView as? LGButton {
cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0)
return cell
}
return cell
}
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 40.0
}
}
MyNewViewController
class NewRquestViewController: RquestTableViewController {
lazy var password:JVFloatLabeledTextField = {
let v = JVFloatLabeledTextField()
v.placeholder = "Password"
return v
}()
override func viewDidLoad() {
super.viewDidLoad()
fields = [password]
}
}

Have you verified that fields really isn't being set properly? I see no reason why it wouldn't be. But I do see another problem: in addition to overriding numberOfSections(in:) and tableView(_,cellForRowAt:), you have to override tableView(_,numberOfRowsInSection:). What you have now is numberOfSections(in:) returning the number of fields, but tableView(_,cellForRowAt:) is expecting to populate the rows with the fields. That means that tableView(_,cellForRowAt:) will be called only when section is 0, so at most you'd see only one field. Instead, change numberOfSections(in:) to return 1, and implement tableView(_,numberOfRowsInSection:) to return fields.count.
