Comment créer un UIPickerView avec un bouton Terminé?

J'ai des difficultés à créer un UIPickerView avec un bouton Terminé à apparaître lorsque les utilisateurs appuient sur un UITextField. Ceci est mon code jusqu'à présent. Tout se passe bien, mais lorsque je tape sur le champ de texte, le clavier apparaît, pas le sélecteur.

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {


@IBOutlet var textField1: UITextField!

let pickerData = ["11", "12", "13"]





@IBAction func textButton(sender: AnyObject) {

    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

    textField1.inputView = picker
    textField1.inputAccessoryView = toolBar




}



override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
    return 1
}

func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return pickerData.count
}

func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return pickerData[row]
}

func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    textField1.text = pickerData[row]
}

func donePicker() {

    textField1.resignFirstResponder()

}

Ajoutez ce code à votre viewDidLoad() au lieu de la méthode

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

textField1.inputView = picker
textField1.inputAccessoryView = toolBar

IPickerView avec un bouton Done? Swift4

Étape 1: Ajouter un fichier texte nommé txt_pickUpData dans ViewController et établir une connexion et un délégué IBOutlet. prenez également une variable UIDatePicker. et prenez un tableau avec une valeur de chaîne qui est affichée sur la roue de sélecteur.

@IBOutlet weak var txt_pickUpData: UITextField!
var myPickerView : UIPickerView!
var pickerData = ["Hitesh Modi" , "Kirit Modi" , "Ganesh Modi" , "Paresh Modi"]

Étape 2: Ajoutez également le délégué de UIPickerView et UITextFiled.

class ViewController: UIViewController , UIPickerViewDelegate, UIPickerViewDataSource, UITextFieldDelegate{

Étape 3: La fonction pickUp pour créer UIPickerView avec ToolBar.

func pickUp(_ textField : UITextField){

// UIPickerView
self.myPickerView = UIPickerView(frame:CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 216))
self.myPickerView.delegate = self
self.myPickerView.dataSource = self
self.myPickerView.backgroundColor = UIColor.white
textField.inputView = self.myPickerView

// ToolBar
let toolBar = UIToolbar()
toolBar.barStyle = .default
toolBar.isTranslucent = true
toolBar.tintColor = UIColor(red: 92/255, green: 216/255, blue: 255/255, alpha: 1)
toolBar.sizeToFit()

// Adding Button ToolBar
let doneButton = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(ViewController.doneClick))
let spaceButton = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
let cancelButton = UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(ViewController.cancelClick))
toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.isUserInteractionEnabled = true
textField.inputAccessoryView = toolBar

 }

Étape 4: Ajout des méthodes de délégué et de source de données de UIPickerView pour afficher les données sur la roue UIPickerView.

//MARK:- PickerView Delegate & DataSource
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
 }
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return pickerData.count
 }
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return pickerData[row]
  }
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
self.txt_pickUpData.text = pickerData[row]
 }
 //MARK:- TextFiled Delegate

 func textFieldDidBeginEditing(_ textField: UITextField) {
self.pickUp(txt_pickUpData)
 }

Étape 5: Ajout de la méthode des deux boutons qui se trouve dans la barre d’outils. L'un est terminé, l'autre est cancelClick. Ce qui est rejeter le UIPickerView.

func doneClick() {
  txt_pickUpData.resignFirstResponder()
 }
func cancelClick() {
  txt_pickUpData.resignFirstResponder()
}

Étape 6: Appel de la fonction de collecte dans la méthode de délégué UITextField.

func textFieldDidBeginEditing(_ textField: UITextField) {
self.pickUp(txt_pickUpData)
}

Il suffit de copier et coller dans votre code.

Je pense qu'il est préférable de créer une classe personnalisée pour supprimer le code du contrôleur.

exemple de Swift 4/5:

import Foundation
import UIKit

protocol ToolbarPickerViewDelegate: class {
    func didTapDone()
    func didTapCancel()
}

class ToolbarPickerView: UIPickerView {

    public private(set) var toolbar: UIToolbar?
    public weak var toolbarDelegate: ToolbarPickerViewDelegate?

    override init(frame: CGRect) {
        super.init(frame: frame)
        self.commonInit()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        self.commonInit()
    }

    private func commonInit() {
        let toolBar = UIToolbar()
        toolBar.barStyle = UIBarStyle.default
        toolBar.isTranslucent = true
        toolBar.tintColor = .black
        toolBar.sizeToFit()

        let doneButton = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(self.doneTapped))
        let spaceButton = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
        let cancelButton = UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(self.cancelTapped))

        toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
        toolBar.isUserInteractionEnabled = true

        self.toolbar = toolBar
    }

    @objc func doneTapped() {
        self.toolbarDelegate?.didTapDone()
    }

    @objc func cancelTapped() {
        self.toolbarDelegate?.didTapCancel()
    }
}

Exemple d'utilisation:

class MyViewController: UIViewController {

    @IBOutlet weak var textField: UITextField!
    fileprivate let pickerView = ToolbarPickerView()
    fileprivate let titles = ["0", "1", "2", "3"]

    override func viewDidLoad() {
        super.viewDidLoad()

        self.textField.inputView = self.pickerView
        self.textField.inputAccessoryView = self.pickerView.toolbar

        self.pickerView.dataSource = self
        self.pickerView.delegate = self
        self.pickerView.toolbarDelegate = self

        self.pickerView.reloadAllComponents()
    }
}

extension MyViewController: UIPickerViewDataSource, UIPickerViewDelegate {

    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        return self.titles.count
    }

    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1
    }

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        return self.titles[row]
    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        self.textField.text = self.titles[row]
    }
}

extension MyViewController: ToolbarPickerViewDelegate {

    func didTapDone() {
        let row = self.pickerView.selectedRow(inComponent: 0)
        self.pickerView.selectRow(row, inComponent: 0, animated: false)
        self.textView.text = self.titles[row]
        self.textField.resignFirstResponder()
    }

    func didTapCancel() {
        self.textField.text = nil
        self.textField.resignFirstResponder()
    }
}

Les gens semblent utiliser le code ici à d'autres questions pour poser la même chose que VBaarathi demandée

Dans Swift3

let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.plain, target: self, action: #selector(donePicker))
let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace, target: nil, action: nil)
let cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.plain, target: self, action: #selector(donePicker))

Ensuite, vous pouvez mettre ce qui suit dans le même fichier Swift

func donePicker (sender:UIBarButtonItem)
{
     // Put something here
}

Swift 3x:

La réponse géniale est déjà donnée, mais voici l'approche différente, créez simplement un pickerView et donnez le inputView et inputAccessoryView comme ceci:

YOUR_TEXTFIELD_NAME.inputView = picker


func addKeyboardToolBar() {

  var nextButton: UIBarButtonItem?
  var keyboardToolBar = UIToolbar(frame: CGRect(x: CGFloat(0), y: 
  CGFloat(0), width: CGFloat(pickerView.frame.size.width), height: CGFloat(25)))
  keyboardToolBar.sizeToFit()
  keyboardToolBar.barStyle = .default
  daysHourTextField.inputAccessoryView = keyboardToolBar
  nextButton = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(self.textFieldShouldReturn))
  keyboardToolBar.items = [UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil), nextButton]

}
