如何在标签中打印uiview（swift3）

Question

I am trying to print a uiview in a label. I don't know if I should put accessibilityIdentifier or not. When I did put accessiblitiyIdentifier in my whole app loaded but was all black.

@IBOutlet var pink: UIView!
@IBOutlet var label: UILabel!
override func viewDidLoad() {
    super.viewDidLoad()

    label.text = pink
}

Answer 1

label.text is of type String and pink is of type UIView! , that shouldn't even compile?

Answer 2

AccessibilityIdentifier可以用于UI自动化脚本，label.text = pink不会被编译，可以使用label.addSubview（pink）
