Acces to viewController from a pickerView - ios

Question

On a sight I have a PickerView and a button. Depending on the choice in the pickerview (I have 4 lines) I would like clicking on a button to go on a specific view. Now, whatever my choice is, I'm always on the same view (saline). Below is my code of the controller. If anyone can help me understand my mistake?
import UIKit
class SommaireGeneralViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
#IBOutlet weak var picker: UIPickerView!
var PlacementAnswer = 0
var liste = ["Sommaire général", "Région Est", "Région Ouest", "Région Sud", "Région Nord"]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
self.picker.delegate = self
self.picker.dataSource = self
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return liste[row]
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return liste.count
}
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString? {
let titleData = liste[row]
let myTitle = NSAttributedString(string: titleData, attributes: [NSFontAttributeName:UIFont(name: "Georgia", size: 10.0)!,NSForegroundColorAttributeName:UIColor.whiteColor()])
return myTitle
}
#IBAction func Voir(sender: AnyObject) {
if (PlacementAnswer == 0) {
self.performSegueWithIdentifier("Saline", sender: self)
} else if (PlacementAnswer == 1){
self.performSegueWithIdentifier("1", sender: self)
return
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
PlacementAnswer = row
}
func prepareForSegue(id: UIStoryboardSegue, sender: AnyObject?) {
if "Saline" == id.identifier {
}
else if "1" == id.identifier {
}
}
}

Hello, finally it's working, I put the code that can be used for others.
Cheers and thank you again for the info
import UIKit
class SommaireGeneralViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
#IBOutlet weak var picker: UIPickerView!
enum ActionSheetTag: Int {
case ActionSheet0
case ActionSheet1
}
var PlacementAnswer = Int()
let liste = ["Sommaire général", "Région Est", "Région Ouest", "Région Sud", "Région Nord"]
override func viewDidLoad() {
super.viewDidLoad()
self.picker.delegate = self
self.picker.dataSource = self
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return liste[row]
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return liste.count
}
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString? {
let titleData = liste[row]
let myTitle = NSAttributedString(string: titleData, attributes: [NSFontAttributeName:UIFont(name: "Georgia", size: 10.0)!,NSForegroundColorAttributeName:UIColor.whiteColor()])
return myTitle
}
#IBAction func Voir(sender: AnyObject) {
if (PlacementAnswer == 0) {
self.performSegueWithIdentifier("Saline", sender: self)
} else if (PlacementAnswer == 1){
self.performSegueWithIdentifier("Autre", sender: self)
}
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if let tag = ActionSheetTag(rawValue: row) {
switch tag {
case .ActionSheet0:
PlacementAnswer = 0
case .ActionSheet1:
PlacementAnswer = 1
}
}
}
}

You tried tag and enum? If your answer is no, try this and return the output to me.
enum ActionSheetTag: Int {
case ActionSheet1
case ActionSheet2
}
.
.
.
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if let tag = ActionSheetTag(rawValue: pickerView.tag) {
switch tag {
case .ActionSheet1:
PlacementAnswer = 0
case .ActionSheet2:
PlacementAnswer = 1
}
}
}
Hope it helps.
