Not able to select tableview's cell - ios

Question

I'm using Xcode 11.2 and I have a view containing 3 tableviews. They all have outlets to the code and their delegates and datasources are correctly set in the viewDidLoad method.
What happens is that the cell highlights when clicked but then it doesn't remain selected (didSelectRow never gets called).
If I click many times rapidly with the left and right mouse buttons the cell will eventually get selected and the didSelectRow gets called.
Also I noticed that the selection almost always works if I click the cell and at the same time scroll the table a little.
Here some of the code:
#IBOutlet weak var linesTableView: UITableView!
#IBOutlet weak var firstLvlTableView: UITableView!
#IBOutlet weak var secondLvlTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
self.linesTableView.dataSource = self
self.linesTableView.delegate = self
self.firstLvlTableView.delegate = self
self.firstLvlTableView.dataSource = self
self.secondLvlTableView.dataSource = self
self.secondLvlTableView.delegate = self
if (CLLocationManager.locationServicesEnabled()) {
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
self.secondLvlTableView.isHidden = true
self.firstLvlTableView.isHidden = false
self.linesTableView.isHidden = true
fetchData()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == linesTableView {
return 0
} else if tableView == firstLvlTableView {
return self.salesAssistantLocalized.count //viewModel.typesOfSale.lists.endIndex
} else if tableView == secondLvlTableView {
return 4 //viewModel.standardTableLevels.lists.endIndex
} else {
return 0
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if tableView == firstLvlTableView {
let cell = tableView.dequeueReusableCell(withIdentifier: "FirstLvlCell", for: indexPath)
cell.textLabel?.text = self.salesAssistantLocalized[indexPath.row]
return cell
} else if tableView == secondLvlTableView {
let cell = tableView.dequeueReusableCell(withIdentifier: "SecondLvlCell", for: indexPath)
cell.textLabel?.text = self.levels[indexPath.row]
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "SaleTypeCell", for: indexPath)
return cell
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
printDebug("Did Select Row \(indexPath.row) for table \(tableView)")
if tableView == firstLvlTableView {
if indexPath.row == 0 {
self.secondLvlTableView.isHidden = false
}
}
}

Answer 1

I've found out what is happening.
All the view controllers are extending from a "BaseViewController" that has a tap gesture recognizer for dismissing the keyboard.
That is causing the problem.
I've simply added a Bool to be able to choose if use it or not:
open var useTapGesture: Bool = true
and then wrapped the tap gesture code with this:
if useTapGesture {
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(BaseViewController.dismissKeyboard))
view.addGestureRecognizer(tap)
}
This way I can use
useTapGesture = false
in my viewDidLoad method.
