一眼看去，我有一个 PickerView 和一个按钮。根据 pickerview 中的选择(我有 4 行)，我想单击一个按钮进入特定 View 。现在，无论我的选择是什么，我总是持相同观点(生理盐水)。下面是我的 Controller 代码。如果有人可以帮助我理解我的错误？
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 {
}
}
}
最佳答案
你好，终于可以用了，我放了可以给别人用的代码。 干杯，再次感谢您提供的信息
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
}
}
}
}
