Question

我需要动态创建带有多个视图的堆栈视图，因为视图数量仅在运行时才知道。

每个视图都包含一个UITextField

class AccountParameterView: UIView {

    public var inputField = UITextField()

        private struct InputFieldParam {
        static let x: CGFloat = 0
        static let y: CGFloat = 50
        static let height: CGFloat = 20
    }

    override init(frame: CGRect){
        super.init(frame: frame)
    }

    convenience init(frame: CGRect, with field: Field){

        self.init(frame: frame)
        self.field = field
        loadElements()
    }


    required init?(coder aDecoder: NSCoder){
        super.init(coder: aDecoder)
        loadElements()
    }

    // Programmatically put the different element in the view
    func loadElements() {

        // shows the input field
        inputField.frame =  CGRect(x: InputFieldParam.x,
                                   y: InputFieldParam.y,
                                   width: frame.width,
                                   height: InputFieldParam.height)

      }

在我的视图控制器中，我创建了一个stackView并添加了几个AccountParameterView：

    func addStackView(){

        for field in MyList!.fields{
            if field.type != FieldType.list{
                // position of the views
                let viewFrame = CGRect(x: ViewConst.x,
                                       y: view.frame.height - ViewConst.vertOffset,
                                       width: view.frame.width,
                                       height: ViewConst.height)
                let myView = AccountParameterView(frame: viewFrame, with: field)

                ParamViews.append(myView)
            }
        }

        let stackView = getStackView()
        for view in ParamViews {
            stackView.addArrangedSubview(view)
        }
        self.view.addSubview(stackView)
    }

我在viewDidLoad中调用此函数。一切都正确显示在屏幕上，但是无法将焦点放在任何UITextField上。我试图使视图控制器成为每个UITextField的委托，但没有任何变化，UITextField仍然无法访问

UIStackView中的UITextFiled没有响应
