UISearchController cancel button dismisses UITabBarController when tapped multiple times in a row - ios

Question

I use a custom search controller that has a tableView for showing the results,
the problem is when tapping the cancel button multiple times it dismisses the tabBarController.
But if i press it normally it acts as it should be.
class UICustomSearchController: UISearchController {
private var suggestedTableView: UITableView!
weak var suggestionDelegate: SearchSuggestionsDelegate?
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
suggestedTableView = UITableView(frame: CGRect(x: 0, y: searchBar.frame.maxY,
width: view.frame.width,
height: view.frame.height - 70))
suggestedTableView.backgroundColor = UIColor.clear
suggestedTableView.tableFooterView = UIView()
view.subviews.forEach {
if $0.isKind(of: UITableView.self) {
$0.removeFromSuperview()
}
}
view.addSubview(suggestedTableView)
suggestedTableView.dataSource = self
suggestedTableView.delegate = self
suggestedTableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")
let tap = UITapGestureRecognizer(target: self, action: #selector(tableTapped))
suggestedTableView.addGestureRecognizer(tap)
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
suggestedTableView.removeFromSuperview()
suggestedTableView = nil
dismiss(animated: false, completion: nil)
}
func reloadSuggestions() {
suggestedTableView.reloadData()
}
private func dismissView() {
searchBar.text = ""
suggestedTableView.removeFromSuperview()
dismiss(animated: false, completion: nil)
suggestionDelegate?.didDismissed()
}
// MARK: - Actions
#objc func tableTapped(tap:UITapGestureRecognizer) {
suggestedTableView.removeGestureRecognizer(tap)
let location = tap.location(in: suggestedTableView)
let path = suggestedTableView.indexPathForRow(at: location)
if let indexPathForRow = path {
tableView(suggestedTableView, didSelectRowAt: indexPathForRow)
} else {
dismissView()
}
}
}
extension UICustomSearchController: UITableViewDataSource, UITableViewDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return suggestionDelegate?.suggestions().count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let list = suggestionDelegate?.suggestions() ?? []
cell.textLabel?.text = list[indexPath.row]
cell.textLabel?.textColor = UIColor.color(from: .blueTabBar)
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let list = suggestionDelegate?.suggestions() ?? []
searchBar.text = list[indexPath.row]
searchBar.becomeFirstResponder()
suggestionDelegate?.didSelect(suggestion: list[indexPath.row])
}
}
And in the viewController that has search:
func initSearchViews() {
// Create the search controller and specify that it should present its results in this same view
searchController = UICustomSearchController(searchResultsController: nil)
searchController.hidesNavigationBarDuringPresentation = false
searchController.searchBar.barTintColor = UIColor.white
searchController.searchBar.tintColor = UIColor.color(from: .blueTabBar)
searchController.searchBar.setValue(Strings.cancel.localized, forKey:"_cancelButtonText")
searchController.suggestionDelegate = self
if let searchTextField = searchController!.searchBar.value(forKey: "searchField") as? UITextField {
searchTextField.placeholder = Strings.search.localized
}
// Make this class the delegate and present the search
searchController.searchBar.delegate = self
}
I tried putting this line in viewController but nothing happened:
definesPresentationContext = true
