infinite loop when selected programmatically a cell - swift

Question

I have a tableview with a textfield in every row.
I need to reload the tableview and programmatically select the row the user had selected.
The user can write what he wants. The data will be deleted when the textfield's editing has ended and added when the textfield has begun editing.
But I get a infinite loop. Please cloud you help me?
My code :
import UIKit
class OptionsItemViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, UITextFieldDelegate {
let context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext
var textFiedlDelegate: UITextField? = nil
var categorySelected: Category?
var options: [String] = []
var nameOptions: [String] = []
var cellSelected: Int = 0
var viewHeight: CGFloat = 0
var selectedRow: IndexPath? = nil
var tableviewNeedToReload: Bool = false
#IBOutlet weak var tableView: UITableView!
#IBOutlet weak var keyboardAlwaysShow: UITextField!
#IBOutlet weak var newFeatureButton: UIBarButtonItem!
private let db = DataBase()
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.dataSource = self
self.textFiedlDelegate?.delegate = self
self.title = categorySelected!.name
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
db.getItemOptions(predicateFormat: "id == \(self.categorySelected!.id)", completion: { results in
self.categorySelected = results.first!
self.options = self.categorySelected!.options as! [String]
DispatchQueue.main.async {
self.tableView.reloadData()
}
})
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(false)
self.viewHeight = self.view.frame.size.height
}
override func viewDidDisappear(_ animated: Bool) {
super.viewDidDisappear(false)
var index = 0
while index < self.options.count {
if self.options[index] != "" {
index += 1
} else {
self.options.remove(at: index)
}
db.setCategoryOptions(category: self.categorySelected!, options: self.options, index: cellSelected)
}
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
self.view.endEditing(true)
}
#IBAction func newFeature(_ sender: Any) {
if self.options.last != "" {
let indexPath: IndexPath = IndexPath(row: self.options.count, section: 0)
self.options.append("")
self.tableView.reloadData()
let cell = tableView(self.tableView, cellForRowAt: indexPath) as! CellItemOptions
cell.nameOptionsItem.becomeFirstResponder()
}
}
// MARK: - TableView Functions
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return options.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let option = options[indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: CellItemOptions.identifier, for: indexPath) as! CellItemOptions
cell.nameOptionsItem.delegate = self
cell.configureCell(with: option)
return cell
}
func textFieldDidBeginEditing(_ textField: UITextField) {
self.cellSelected = options.index(of: textField.text!)!
let indexPath: IndexPath = IndexPath(row: self.cellSelected, section: 0)
self.tableView.reloadData()
let cell = self.tableView.cellForRow(at: indexPath) as! CellItemOptions
cell.nameOptionsItem.becomeFirstResponder()
}
func textFieldDidEndEditing(_ textField: UITextField) {
if textField.text! == "" {
if self.options[cellSelected] != "" {
db.setRemoveDetailsItem(category: self.categorySelected!, index: cellSelected)
}
self.options.remove(at: cellSelected)
} else {
self.options[cellSelected] = "\(textField.text!)"
db.setAddDetailsItem(category: self.categorySelected!, index: cellSelected)
}
db.setCategoryOptions(category: self.categorySelected!, options: self.options, index: cellSelected)
}
// MARK: - Keyboard
func keyboardWillShow(_ notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if self.view.frame.size.height == self.viewHeight {
self.view.frame.size.height -= keyboardSize.height
}
}
}
func keyboardWillHide(_ notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
if self.view.frame.origin.y != self.viewHeight {
self.view.frame.size.height += keyboardSize.height
}
}
}
}
class CellItemOptions: UITableViewCell {
static let identifier = "OptionsItemCell"
#IBOutlet weak var nameOptionsItem: UITextField!
private let tableView = OptionsItemViewController()
func configureCell(with cell: String) {
nameOptionsItem.text = cell
}
}
EDIT :
The loop is due to the reload data...
Like I reload data in textFieldDidBeginEditing(), the view is reloaded more and more ... And I need to textFieldDidBeginEditing() to know the row selected by the user.
