ios – 如何以编程方式创建自定义视图,具有控件文本字段,按钮等

var view = MyCustomView(frame: CGRectZero)

..在viewDidLoad方法中。问题是在模拟器中没有初始化视图。

我已经在当前ViewController的storyboard中设置了类。

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(50,120,100)
        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)
    }
