Ios 更改另一个UIPickerView后更改UIPickerView的内容

我有一个有很多PickerView的表单，一个表单的内容是在另一个PickerView上选择一个内容时给出的，所以当我们更改值时，行必须更改。我的UIPickerView工作如下：

import UIKit

@objc
protocol DemandeGratuiteViewControllerDelegate {
    optional func toggleLeftPanel()
    optional func collapseSidePanels()
}

class DemandeGratuiteViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource , UITextFieldDelegate {

    var delegate: DemandeGratuiteViewControllerDelegate?

    @IBOutlet var tfProjet: UITextField!
    @IBOutlet var tfLogement: UITextField!
    @IBOutlet var libelleValeurActuelleDuBien: UILabel!
    @IBOutlet var libelleLoyer: UILabel!
    @IBOutlet var tfValeurActuelleBien: UITextField!
    @IBOutlet var tfLoyer: UITextField!
    @IBOutlet var tfProfession: UITextField!
    @IBOutlet var tfContrat: UITextField!
    @IBOutlet var pickerView: UIPickerView!
    @IBOutlet weak var RevenusNetsConstraint: NSLayoutConstraint!
    @IBOutlet weak var libelleDeclare: UILabel!

    func handleTap(sender: UITapGestureRecognizer) {
        if sender.state == .Ended {
            view.endEditing(true)
        }
        sender.cancelsTouchesInView = false
    }


    @IBAction func menuTapped(sender: AnyObject) {
        print(delegate)
        delegate?.toggleLeftPanel?()
    }


    // returns the number of 'columns' to display.
    func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int{
        return 1
    }

    // returns the # of rows in each component..
    func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{
        if pickerView.tag == 0 {
            return pvProjetData.count
        }
        else if pickerView.tag == 1 {
            return pvLogement.count
        }
        else if pickerView.tag == 2 {
            return pvProfession.count
        }
        return 1
    }

    func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        if pickerView.tag == 0 {
            return pvProjetData[row]
        }
        else if pickerView.tag == 1 {
            return pvLogement[row]
        }
        else if pickerView.tag == 2 {
            return pvProfession[row]
        }
        return ""
    }

    func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int)
    {
        if pickerView.tag == 0 {
            tfProjet.text = pvProjetData[row]
            self.tfProjet.endEditing(true)
        }
        else if pickerView.tag == 1 {
            tfLogement.text = pvLogement[row]
            self.tfLogement.endEditing(true)
            tfLogementDidChange()
            print(tfLogement.text)
        }
        else if pickerView.tag == 2 {
            tfProfession.text = pvProfession[row]
            self.tfProfession.endEditing(true)
        }
    }

}

因此，我想通过在tfProfession中选择的内容更改tfContrat的UIPickService：

• 如果选择了第一项，我将显示pvContrat1
• 否则，如果选择第二项，我将显示PVCONTRT 2
• 等等

看起来您正在创建14个选择器视图。这似乎是一个非常糟糕的用户界面。你应该重新思考你的设计。@duncac你怎么想？我对你的应用程序和你试图解决的问题一无所知。
