我有一个包含许多PickerView的表单，当在另一个PickerView上选择内容时会给出一个内容，因此当我们更改值时，必须更改该行。我的UIPickerView就是这样的：
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!

@IBAction func menuTapped(sender: AnyObject) {

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

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]

}
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)
}
}
}
所以我想用tfProfession中选择的内容更改tfContrat的UIPickerVie：
