My pickerview is not displaying for some reason even after reloading all components. I click start and it just does not load up the pickerview as I want this to load and then you can select an option and go to the next question?
import UIKit
class QuestionsViewController: UIViewController, UIPickerViewDelegate {
#IBOutlet weak var Next: UIButton!
#IBOutlet weak var pickerview: UIPickerView!
#IBOutlet weak var itemLabel: UILabel!
#IBOutlet weak var label1: UILabel!
#IBOutlet weak var Question: UILabel!
#IBAction func Next(_ sender: Any) {
cQuestion.currentQuestion = cQuestion.currentQuestion + 1
pickerview.reloadAllComponents()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//var LabelText: String = ""
//var arrayOfQuestions: [String] = ["&","&&","||","None of above"]
//var correctAns:String = ""
//var currentQuestion = 0
let cQuestion = Questions()
//init(arrayOfQuestions:String, correctAns:String, LabelText:String) {
//self.arrayOfQuestions = [arrayOfQuestions]
// self.correctAns = correctAns
// self.LabelText = LabelText
//}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
itemLabel.text = cQuestion.arrayOfQuestions[0]
}
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{
if(cQuestion.currentQuestion == 0) {
Question.text = "Q1. Which is a logical OR operator"
return cQuestion.arrayOfQuestions.count
} else if (cQuestion.currentQuestion == 1) {
Question.text = "Q2. Compiler generates_file"
return cQuestion.arrayOfQuestions.count
}
hide()
Question.text = "You have finished"
Next.isHidden = true
return cQuestion.arrayOfQuestions.count
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String?{
if(cQuestion.currentQuestion == 0) {
return cQuestion.arrayOfQuestions[row]
} else if (cQuestion.currentQuestion == 1) {
return cQuestion.arrayOfQuestions[row]
}
return cQuestion.arrayOfQuestions[row]
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int){
if (cQuestion.currentQuestion == 0) {
let itemSelected = cQuestion.arrayOfQuestions[row]
itemLabel.text = itemSelected
} else if (cQuestion.currentQuestion == 1) {
let itemSelected = cQuestion.arrayOfQuestions[row]
itemLabel.text = itemSelected
}
}
func hide() {
pickerview.isHidden = true
itemLabel.isHidden = true
}
}
My guess: it looks like as soon as numberOfRowsInComponent is called (which it does as soon as it prepares to be added to the view) you also call hide() which in turns seems to set your pickerView to isHidden = true. I don't see anywhere in your code where isHidden is subsequently set to false.
If that happens to not be the case, also check what the value of pickerview.dataSource is to make sure it's not nil.

You have forgotten to subscribe the delegate and data sources to the PickerView..

return true

}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
if hospNameField.isFirstResponder {
return hosp[row]
} else if teamNameField.isFirstResponder {
return team[row]
} else if mdNameField.isFirstResponder {
return mds[row]
}
return nil
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
/**

you have executed teamNameField.isFirstResponder twice
*/
if hospNameField.isFirstResponder {
let itemselected = hosp[row]
hospNameField.text = itemselected
} else if teamNameField.isFirstResponder {
let itemselected = team[row]
teamNameField.text = itemselected
} else if mdNameField.isFirstResponder {
let itemselected = mds[row]
mdNameField.text = itemselected
}
}
}
I think your code is wrong in didSelectRow. check the first and second if, both run the same condition.
if teamNameField.isFirstResponder {
let itemselected = hosp[row]
hospNameField.text = itemselected
} else if teamNameField.isFirstResponder {
let itemselected = team[row]
teamNameField.text = itemselected
} else if mdNameField.isFirstResponder {
let itemselected = mds[row]
mdNameField.text = itemselected
}
I think you should change the first if to if hospNameField.isFirstResponder {..}
I looked on here for an answer, but do not believe this question has been answered. I have multiple text boxes that use a couple different pickers. I would like for the first text box the user selects the material, and then based on the material selected they can only see the type of material that corresponds to it. Below in my code when I am naming my arrays you can see that it says typeBrassData or typeCopperData so if the user selects Brass or Copper above only the options for Brass show, does anyone know how to do this? Below is the code I was using when it was only 2 picker views. Thanks all in advance!

You can use the dictionary data structure to set the values of the pickerviews
var materialSelected = ""
var typeArr = [String]()
//I have done for only three materials obviously you can extend it...

}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {

return materialData.count
} else if pickerView == pickerType{
typeArr = dict[materialSelected] as! [String]
return typeArr.count
}
return 1
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
if pickerView == pickerMaterial {
return materialData[row]

Im trying to have two different pickerViews on the same viewController and let them represent different data. I have tried a different ways to do this, but both picker views showing same Data, but can't put it all together. Any help would be awesome!
here is my code:

let pickerView = UIPickerView()
var Eventstype = ["Birthday" , "Marriege" , "Get together", "Conference"]
#IBOutlet weak var datepickertxt: UITextField!
var datepicker = UIDatePicker()
#IBOutlet weak var Duration: UITextField!
let duration = UIPickerView()
var Durations = ["6-8","1-5","7-9","10-12"]
override func viewDidLoad() {
super.viewDidLoad()
createDatePicker()
pickerView.delegate = self
pickerView.dataSource = self

This is done by tag or else yo can check in delegate like
if pickerView == duration
Set the tags for pickerview in viewDidLoad as shown below,
pickerView.tag = 0
duration.tag = 1
class ViewController: UIViewController {
#IBOutlet var txtDuration: UITextField!
#IBOutlet var txtEventType: UITextField!
var pickerView = UIPickerView()
var arrEventType : [String] = []
var arrDuration : [String] = []
var currentTextField : UITextField?
override func viewDidLoad() {
super.viewDidLoad()
arrEventType = ["Birthday" , "Marriage" , "Get together", "Conference"]
arrDuration = ["6-8","1-5","7-9","10-12"]
}
}
extension ViewController : UIPickerViewDelegate , UIPickerViewDataSource {
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
if currentTextField == txtEventType {
return arrEventType.count
} else if currentTextField == txtDuration {
return arrDuration.count
} else {
return 0
}
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
if currentTextField == txtEventType {
return arrEventType[row]
} else if currentTextField == txtDuration {
return arrDuration[row]
} else {
return ""
}
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if currentTextField == txtEventType {
txtEventType.text = arrEventType[row]
} else if currentTextField == txtDuration {
txtDuration.text = arrDuration[row]
}
}
}
extension ViewController : UITextFieldDelegate {
func textFieldDidBeginEditing(_ textField: UITextField) {
self.pickerView.delegate = self
self.pickerView.dataSource = self
currentTextField = textField
if currentTextField == txtEventType {
currentTextField?.inputView = pickerView
} else if currentTextField == txtDuration {
currentTextField?.inputView = pickerView
}
}
}
Above lines of code may solve your issue with just one UIPickerView and without tags

I think you have IBOutlet of pickerview is not connected properly, Make sure you need to check in Storyboard or Xib pickerview is connected properly or not?
i hope it will work for you
I have multiple UIPickerViews in a single ViewController. I believe I've set datasources and delegates properly, but, when I run the code, the PickerViews are not populating. What I am getting is "()" displaying in all the PickerViews.
Anyone have ANY idea what the heck I'm doing wrong? Everyplace I've looked/googled intimates I have this set up correctly.
