更改颜色TextField以响应按钮颜色

Question

伙计们，当我按下collectionView的颜色时，我必须更改TextField的颜色。我正在尝试使用此代码，但它不会改变任何内容。我在做什么错了？

sampleTextField插入视图“ labelV”

    let sampleTextField =  UITextField()

    sampleTextField.attributedPlaceholder = NSAttributedString(string: "text",
                                                               attributes: [NSAttributedString.Key.foregroundColor: UIColor.white])
    sampleTextField.textColor = UIColor.white
    sampleTextField.autocorrectionType = UITextAutocorrectionType.no
    sampleTextField.keyboardType = UIKeyboardType.default
    sampleTextField.returnKeyType = UIReturnKeyType.done
    sampleTextField.clearButtonMode = UITextField.ViewMode.whileEditing;
    sampleTextField.contentVerticalAlignment = UIControl.ContentVerticalAlignment.center
    sampleTextField.isUserInteractionEnabled = true



func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    debugPrint("sucaaaa")
    var cell = delegate2?.labelV.sampleTextField.textColor?.cgColor
    cell = datasource[indexPath.item].color as! CGColor

}



    var labelV: LabelView = LabelView(frame: .zero, name: "tipo")
