Multiple UIPickerView in one ViewController - ios

Question

I have two UiTextfield which are supposed to show different UiPickerView when clicked on a respective UiTextfield.......
so i used this
if(textField.isFirstResponder() == true)
to find which textfield has been clicked...this does not work
class ViewController: UIViewController, UIPickerViewDataSource , UIPickerViewDelegate {
var pickerData = ["11", "12", "13"]
var pickerDataOthr = ["ada","daad","ada","daad","ada","daad","ada","daad"]
#IBOutlet weak var textField: UITextField!
#IBOutlet weak var textFieldTwo: UITextField!
#IBOutlet weak var tftw: UITextField!
func pickerCode(){
let picker: UIPickerView
picker = UIPickerView(frame: CGRectMake(0, 200, view.frame.width, 300))
picker.backgroundColor = .whiteColor()
picker.showsSelectionIndicator = true
picker.delegate = self
picker.dataSource = self
let toolBar = UIToolbar()
toolBar.barStyle = UIBarStyle.Default
toolBar.translucent = true
toolBar.tintColor = UIColor(red: 76/255, green: 217/255, blue: 100/255, alpha: 1)
toolBar.sizeToFit()
let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Plain, target: self, action: "donePicker")
let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
let cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Plain, target: self, action: "donePicker")
toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.userInteractionEnabled = true
}
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int{
return 1
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{
var count: Int
if(textField.isFirstResponder() == true)
{
count = pickerData.count
}
else
{
count = pickerDataOthr.count
}
return count
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
var stro:String
if(textField.isFirstResponder() == true)
{
stro = pickerData[row]
}
else
{
stro = pickerDataOthr[row]
}
return stro
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if(textField.isFirstResponder() == true)
{
textField.text = pickerData[row]
}
else
{
textFieldTwo.text = pickerDataOthr[row]
}
}
func donePicker(){
if(textField.isFirstResponder() == true)
{
textField.resignFirstResponder()
}
else
{
textFieldTwo.resignFirstResponder()
}
}
func canclePicker(){
if(textField.isFirstResponder() == true)
{
textField.resignFirstResponder()
}
else
{
textFieldTwo.resignFirstResponder()
}
}
}

Answer 1

Adding a tag to every textfield
var tagMaster: Int!
func setUpTag(){
textField.tag = 1
textField.delegate = self
textFieldtwo.tag = 2
textFieldtwo.delegate = self
}
and in the picker helper methods idetify the clicked picker by the picker tags. In place of
textField.isFirstResponder()
i used
textField.tag
