I have two UIPickerviews that appear on one ViewController. I have tried to follow the following tutorial.
I have followed the suggestion in that I have tagged each of the UITextFields (I have 4 in total). See the the image.
Below is the code for the UIPickerViews.
extension DriverViewController: UIPickerViewDelegate, UIPickerViewDataSource {
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
if pickerView.tag == 0 {
return tracks.count
} else {
return drivers.count
}
}
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
if pickerView.tag == 0 {
return "\(tracks[row])"
} else {
return "\(drivers[row])"
}
}
The problem I am having is that the tracks array appear on all of the UITextfields.
Below is the code for each of the Arrays and the title of the UIPickerView.
override func viewDidLoad() {
super.viewDidLoad()
tracks = ["Melbourne", "Manama", "Shanghai", "Baku",
"Barcelona", "Monaco", "Montreal","Le Castellet","Spielberg",
"Silverstone","Hockenheim","Budapest","Francorchamps","Monza","Singapore","Sochi","Suzuka","Austin","Interlagos","Abu Dhabi"]
drivers = ["Lewis Hamilton","Antonio Giovinazzi","Kimi Raikkonen","Charles Leclerc","Sebastian Vettel","Romain Grosjean","Kevin Magnussen","Lando Norris",
"Carlos Sainz","Valtteri Bottas","Sergio Perez","Lance Stroll","Pierre Gasly","Max Verstappen","Nico Hulkenberg","Daniel Ricciardo","Alexander Albon","Daniil Kvyat","Robert Kubica","George Russell"]
createTrackPicker()
createDriverPicker()
createToolBar()
// Do any additional setup after loading the view.
}
func createTrackPicker() {
let trackPicker = UIPickerView()
trackPicker.delegate = self
TrackTextField.inputView = trackPicker
}
func createDriverPicker() {
let driverPicker = UIPickerView()
driverPicker.delegate = self
firstTextField.inputView = driverPicker
secondTextField.inputView = driverPicker
thirdTextField.inputView = driverPicker
}
func createToolBar() {
let toolBar = UIToolbar()
toolBar.sizeToFit()
let doneButton = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(ViewController.dismissKeyboard))
toolBar.setItems([doneButton], animated: false)
toolBar.isUserInteractionEnabled = true
TrackTextField.inputAccessoryView = toolBar
firstTextField.inputAccessoryView = toolBar
secondTextField.inputAccessoryView = toolBar
thirdTextField.inputAccessoryView = toolBar
}
@objc func dismissKeyboard() {
view.endEditing(true)
}
