ios - 从不同的pickerView中获取值(value)

Question

目前我正在使用 Xcode 7 Swift 开发移动应用程序。我的应用程序使用 pickerView。我有 7 个 pickerView。

我想要做的是，按下按钮后获取每个 pickerView 的值。但我不知道怎么办。我还是 Xcode 和 Swift 的初学者。

这是我的编码

    @IBOutlet weak var vomit: UIPickerView!
    @IBOutlet weak var headache: UIPickerView!
    @IBOutlet weak var muscle: UIPickerView!
    @IBOutlet weak var abdominal: UIPickerView!
    @IBOutlet weak var skin: UIPickerView!
    @IBOutlet weak var bleeding: UIPickerView!
    @IBOutlet weak var fever: UIPickerView!

    var pickerVomit: [String] = [String]()
    var pickerHead: [String] = [String]()
    var pickerMuscle: [String] = [String]()
    var pickerAbdominal: [String] = [String]()
    var pickerSkin: [String] = [String]()
    var pickerBleeding: [String] = [String]()
    var pickerFever: [String] = [String]()


    var vomitData = []
    var headData = []
    var muscleData = []
    var abdominalData = []
    var skinData = []
    var BleedingData = []
    var feverData = []


    @IBAction func backMenu(sender: AnyObject) {
        self.dismissViewControllerAnimated(true , completion: nil)
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        //Looks for single or multiple taps.
        //let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "dismissKeyboard")
        //view.addGestureRecognizer(tap)

        vomitData = ["No","Yes"]
        headData = ["No","Yes"]
        muscleData = ["No","Yes"]
        abdominalData = ["No","Yes"]
        skinData = ["No","Yes"]
        BleedingData = ["No","Yes"]
        feverData = ["No","Yes"]

    }

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

    func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        if (pickerView.tag == 1){
            return vomitData.count
        }
        else if (pickerView.tag == 2){
            return headData.count
        }
        else if (pickerView.tag == 3){
            return muscleData.count
        }
        else if (pickerView.tag == 4){
            return abdominalData.count
        }
        else if (pickerView.tag == 5){
            return skinData.count
        }
        else if (pickerView.tag == 6){
            return BleedingData.count
        }
        else {
            return feverData.count
        }
    }

    func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        if (pickerView.tag == 1){
            return "\(vomitData[row])"
        }
        else if (pickerView.tag == 2){
            return "\(headData[row])"
        }
        else if (pickerView.tag == 3){
            return "\(muscleData[row])"
        }
        else if (pickerView.tag == 4){
            return "\(abdominalData[row])"
        }
        else if (pickerView.tag == 5){
            return "\(skinData[row])"
        }
        else if (pickerView.tag == 6){
            return "\(BleedingData[row])"
        }
        else {
            return "\(feverData[row])"
        }

    }

我真的希望有人能帮助我度过这个难关。谢谢。

首先你有 7 个 pickerview。

@IBOutlet weak var vomit: UIPickerView!
@IBOutlet weak var headache: UIPickerView!
@IBOutlet weak var muscle: UIPickerView!
@IBOutlet weak var abdominal: UIPickerView!
@IBOutlet weak var skin: UIPickerView!
@IBOutlet weak var bleeding: UIPickerView!
@IBOutlet weak var fever: UIPickerView!

7 个数组包含根据 pickerview 的值。

var vomitData = []
var headData = []
var muscleData = []
var abdominalData = []
var skinData = []
var BleedingData = []
var feverData = []

现在，您希望在单击按钮时从所选行的每个选择器中获得值!因此，在按钮操作方法中添加以下代码，

let int_Vomit = self.vomit.selectedRowInComponent(0)
print("\(vomitData[row])")

对其他 pickerView 继续进行相同的操作。
