create instance of custom xib class make gesture recognizer don't work

Question

first I create a .xib file and named it RadioBtnView and connect it to a custom UIView class :

class CheckBtnView: UIView {
    @IBOutlet weak var mainView: UIView!
    @IBOutlet weak var CheckBtn: UIButton!
    @IBOutlet weak var checkDescription: UILabel!
    
    var status = false {
        didSet {
            if status {
                CheckBtn.backgroundColor = .orange
            } else {
                CheckBtn.backgroundColor = .clear
            }
        }
    }
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupViews()
    }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
        setupViews()
    }
    
    
    private func setupViews(){
        Bundle.main.loadNibNamed("CheckBtnView", owner: self, options: nil)
        addSubview(mainView)
        mainView.frame = self.bounds
        mainView.autoresizingMask = [.flexibleHeight,.flexibleWidth]

    }
}

then try to add an instance of RadioBtnView programmatically in viewController and add gesture recognizer to it :

let radio = RadioBtnView()
scrollContainerView.addSubview(radio)
radio.translatesAutoresizingMaskIntoConstraints = false
radio.topAnchor.constraint(equalTo: entry.bottomAnchor, constant: 15).isActive = true
radio.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 38).isActive = true
radio.isUserInteractionEnabled = true
let radioGesture = UITapGestureRecognizer(target: self, action: #selector(change(_:)))
radio.addGestureRecognizer(radioGesture)

but the change(_:) function doesn't respond seems like it didn't call

is this for creating the xib view programmatically or something else?

我终于知道原因了......我只是删除了radio.translatesAutoresizingMaskIntoConstraints = false并添加了radio.frame = CGRect(x:50,y:100,width:120,height:20)并且每一个思考工作似乎我们都可以不以编程方式添加 xib 视图
