Reloading Particular Row of PickerView in swift

I have a pickerView consisting of a label and image. i'm updating that image when pickerview is tapped on that particular. but to show the change of image i have to reload pickerView. and when i reload it goes back to the first row. is there any way to reload only that particular row of pickerView?

Code:

if selectedRows.contains(contactPerson.text!) {
                      FilteredQuestion_Images[row] = UIImage(named: "Unchecked Checkbox-26")!
                    let image = FilteredQuestion_Images[row]
                    imageView = UIImageView(image: image)

                    if let itemToRemoveIndex = selectedRows.index(of: contactPerson.text!) {
                        selectedRows.remove(at: itemToRemoveIndex)
                        ContactPersons_Multiple.remove(at: itemToRemoveIndex)
                    }

                    self.dropdownPicker.reloadAllComponents()

                }else {


                    selectedRows.append(contactPerson.text!)
                    self.imageName = "Checked Checkbox-26"

                    FilteredQuestion_Images[row] = UIImage(named: "Checked Checkbox-26")!

                    let image = FilteredQuestion_Images[row]
                    imageView = UIImageView(image: image)

                    self.dropdownPicker.reloadAllComponents()

                    }
                }

Code of ViewForRow:

     func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
  let customeView = UIView(frame: CGRect(x: 0, y: 0, width: self.dropdownPicker.rowSize(forComponent: 0).width, height: 30))

            // for label
            let label = UILabel(frame: CGRect(x: 0, y: 0, width: customeView.frame.width - 35, height: 30))
            label.textAlignment = .left

            label.text = self.ContactPers[row]

            if FilteredContactsSelected == true {
                label.text = FilteredContactsNames[row]
            }


            let image = FilteredQuestion_Images[row]//UIImage(named: imageName)
            imageView = UIImageView(image: image)



            imageView?.frame = CGRect(x: self.dropdownPicker.rowSize(forComponent: 0).width - 36 , y: 0, width: 26, height: 26)

            customeView.addSubview(imageView!)
            customeView.addSubview(label)//pickerLabel)

            return customeView//pickerLabel
}

No such system method. However, if you are using custom view, you can try something like this:

(pickerView.view(forRow: <#T##Int#>, forComponent: <#T##Int#>) as? MyCustomView).image = newImage

Edit:

First you need you need to add view tags to your custom view elements(you can define two constants for this):

label.tag = 10
imageView.tag = 20

And after a selection occurs, you need to refresh your view's state. You can do that by:

if let myView = pickerView.view(forRow: row, forComponent: 0) as? UIView,
        let label = myView.viewWithTag(10) as? UILabel,
        let imageView = myView.viewWithTag(20) as? UIImageView{

        label.text = FilteredContactsNames[row]
        imageView.image = ilteredQuestion_Images[row]
}
