在UiView

Question

我正在尝试在UIView中添加标签。 UIView已通过故事板添加到viewcontroller中。

每当我尝试添加标签（使用文本框）时，它会将其添加到视图控制器而不是uiview中。这是代码，我哪里错了？

protocol AddContentUIViewDelegate: class {
    func meathodForAddingChip(name: String)
}

class AddContentUIView: UIView {

    weak var delegate:AddContentUIViewDelegate?

    func addLabelFunc(name: String) {
        delegate?.meathodForAddingChip( name: name)
    }

    func addSV(label: UILabel){
        self.addSubview(label)
    }
}

class TheVC: UIViewController, AddContentUIViewDelegate {

    @IBOutlet weak var searchTextField: SearchTextField!
    @IBOutlet weak var contentUIView: AddContentUIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        contentUIView.delegate = self

        //Test to add label
        contentUIView.addLabelFunc(name: item.title)
    }

    func meathodForAddingChip(name: String) {

        let label = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 21))        
        label.textColor = .black
        label.center = CGPoint(x: 160, y: 284)
        label.textAlignment = .center
        label.text = name
        contentUIView.addSV(label: label)
    }
}

问题出在这一行

  label.center = CGPoint(x: 160, y: 284)

将其评为超出帧边界
