How to create multiple pickerviews programmatically - ios

Question

I am trying to create a separate pickerview for each textbox that is selected. so far the closest I have gotten is having the same pickerview for each of the text boxes that need their own separate list of items to choose from.
class MainViewController: UIViewController, UITextFieldDelegate, UIPickerViewDataSource, UIPickerViewDelegate {
var dogBreedPickerArray = ["German Shepherd", "Huskie", "cray cray"]
var catBreedPickerArray = ["savanna", "cheetoh", "bengal"]
var maleFemalePickerArray = ["Male", "Female"]
var dogBreedPicker = UIPickerView()
var dogBreedPicker = UIPickerView()
var catBreedPicker = UIPickerView()
var maleFemalePicker = UIPickerView()
#IBOutlet var dogBreedTextBox: UITextField!
#IBOutlet var catBreedTextBox: UITextField!
#IBOutlet var maleFemaleTextBox: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
dogBreedPicker.delegate = self
dogBreedPicker.dataSource = self
dogBreedTextBox.inputView = dogBreedPicker
dogBreedTextBox.delegate = self
}
// dog picker functions
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return dogBreedPickerArray.count
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
petBreedTextBox.text = dogBreedPickerArray[row]
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return dogBreedPickerArray[row]
}
}

Answer 1

its just a example may be it help to you
after selecting any text field asign textfield tag to picker and reload the component.
// variable
var heightInch:[Int] = [Int]()
var heightfeet:[Int] = [Int]()
var heightCms:[Int] = [Int]()
delegate methods
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
if picker.tag == 1{
return 2
}else{
return 1
}
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
if picker.tag == 1{
switch component {
case 0:
return heightfeet.count
default:
return heightInch.count
}
}else{
return heightCms.count
}
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
if picker.tag == 1{
switch component {
case 0:
return String(heightfeet[row])
default:
return String(heightInch[row])
}
}else{
return String(heightCms[row])
}
