如何在具有控件文本字段、按钮等的 swift 中以编程方式创建自定义视图

我试图使用ViewController中的以下代码从另一个类访问MyCustomView.敏捷的

var view = MyCustomView(frame: CGRectZero)

用viewDidLoad法.问题是该视图没有在模拟器中初始化.

我已经在故事板中为当前的ViewController设置了类.

class MyCustomView: UIView {
    var label: UILabel = UILabel()
    var myNames = ["dipen","laxu","anis","aakash","santosh","raaa","ggdds","house"]

    override init(){
        super.init()
    }

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

    required init(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    func addCustomView() {
        label.frame = CGRectMake(50, 10, 200, 100)
        label.backgroundColor=UIColor.whiteColor()
        label.textAlignment = NSTextAlignment.Center
        label.text = "test label"
        label.hidden=true
        self.addSubview(label)

        var btn: UIButton = UIButton()
        btn.frame=CGRectMake(50, 120, 200, 100)
        btn.backgroundColor=UIColor.redColor()
        btn.setTitle("button", forState: UIControlState.Normal)
        btn.addTarget(self, action: "changeLabel", forControlEvents: UIControlEvents.TouchUpInside)
        self.addSubview(btn)

        var txtField : UITextField = UITextField()
        txtField.frame = CGRectMake(50, 250, 100,50)
        txtField.backgroundColor = UIColor.grayColor()
        self.addSubview(txtField)
    }
