I have uiviewcontroller with uitextfields, when users tap on the textfields uipickerview appears as shown in the attachment.
How can I make multiple uipickerview? For example, when the user tap on the countries textfields a pickerview shows up with countries array data and when users tap on the gender textfields uipickerview shows the genders array data and so on. I tried but only able to do it for one array which is countries as shown in my code. would appreciate if you could show me how to do it for the rest of my uitextfields.
import UIKit
class testVC: UIViewController,UITextViewDelegate,UINavigationControllerDelegate,UIImagePickerControllerDelegate,UIPickerViewDelegate,UIPickerViewDataSource {
var countries = ["USA","UK","Spain" ]
var gender = ["Male","Female","Both"]
var language = ["English","French","Spanish","Other"]
override func viewDidLoad() {
super.viewDidLoad()
var pickerView = UIPickerView(frame: CGRectMake(0, 200, view.frame.width, 100))
pickerView.backgroundColor = .whiteColor()
pickerView.showsSelectionIndicator = true
var 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()
pickerView.delegate = self
pickerView.dataSource = self

You don't need multiple UIPickerView. Instead you need to set picker view data source based on first responder text view. Also you should implement textFieldShouldBeginEditing delegate method to reload content of picker view by calling its reloadAllComponents method
var pickerView : UIPickerView!
override func viewDidLoad() {
self.pickerView = UIPickerView(frame: CGRectMake(0, 200, view.frame.width, 100))
NSNotificationCenter.defaultCenter().addObserver(self, selector: ("updatePicker"), name: UITextFieldTextDidBeginEditingNotification, object: nil)
}
func updatePicker(){
self.pickerView.reloadAllComponents()
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
if countriesTxt.isFirstResponder(){
return countries.count
}else if genderTxt.isFirstResponder(){
return gender.count
}
// continue this way and implement all cases
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String! {
if countriesTxt.isFirstResponder(){
return countries[row]
}else if genderTxt.isFirstResponder(){
return gender[row]
}
// continue this way and implement all cases
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if countriesTxt.isFirstResponder(){
var itemselected = countries[row]
countriesTxt.text = itemselected
}else if genderTxt.isFirstResponder(){
var itemselected = gender[row]
genderTxt.text = itemselected
}
// ...
}
