今天学习了一个例子，参考地址：http://blog.csdn.net/chenyblog/article/details/50537866
直接上代码了：
// ”导入头文件“require("UIView, UILayer, UIButton, UILabel, UIColor, UITextField, UIFont,UIAlertView");defineClass('ViewController : ViewController <UIAlertViewDelegate>', {            viewDidLoad:function(){                self.ORIGviewDidLoad();                // 全局变量 index                index = (function () {                         var counter = 0;                         return function () {return counter += 1;}                         })();                // Objective-C 里的常量不能直接在 JS 上使用，可以直接在 JS 上用具体值代替，或者在 JS 上重新定义同名的全局变量                UITextBorderStyleNone = 0;                UITextBorderStyleLine = 1;                UITextBorderStyleBezel = 2;                UITextBorderStyleRoundedRect = 3;                // 全局变量                btn = null;                txfName = null;                lblDesc = null;                persent = 0.5;                screenWidth = self.view().bounds().width;  // 获取控制器中的属性                // 设置UI                setupUI();            },            touchesBegan_withEvent:function(touches, event) {                txfName.resignFirstResponder();                // var btn = btn1;//self.view().viewWithTag(1000);                var i = index();                btn.setTitle_forState('' + i, 0);                btn.setTag(i+1000);            },            // 自定义的方法命名不能加下划线！！！            btnClick:function(sender) {                var tag = sender.tag();                var alert = UIAlertView.alloc().initWithTitle_message_delegate_cancelButtonTitle_otherButtonTitles("提示", "按钮的tag为 " + (parseInt(tag)-1000), self, "确定", null);                alert.show();            },            alertView_clickedButtonAtIndex:function(alertView, buttonIndex) {                 console.log("buttonIndex=" + buttonIndex);            },            textChange:function(sender) {               //此处需将oc字符串转为js字符再进行赋值               var str = sender.text().toJS();               console.log('textChange = ' + str);               lblDesc.setText('  ' + str);            }})function setupUI() {    var i = index();    var cornerRadius = 5;    var margin = 8;    var x = 0;    var width = screenWidth - 2 * x;    var height = 100;    var margin16 = 16;    var y = (height + margin) * 1;   // 此处应该 * i    var view = UIView.alloc().initWithFrame({x:x, y:y, width:width, height:height});    view.setBackgroundColor(UIColor.greenColor());    self.view().addSubview(view);    // 创建文本框    txfName = UITextField.alloc().init();    txfName.setBorderStyle(UITextBorderStyleRoundedRect);    var txfX = margin;    var txfY = margin;    var txfW = screenWidth * persent;    var txfH = 35;    var txfF = {x:txfX, y:txfY, width:txfW, height:txfH};    txfName.setFrame(txfF);    console.log("frame=" + txfName.frame());    // 监听文本框值变化事件    txfName.addTarget_action_forControlEvents(self, 'textChange:', 1 << 17);    view.addSubview(txfName);    // 创建label    lblDesc = UILabel.alloc().init();    var lblX = txfX;    var lblW = txfW;    var lblH = txfH;    var lblY = height - lblH - margin;    var lblF = {x:lblX, y:lblY, width:lblW, height:lblH};    lblDesc.setFrame(lblF);    console.log("lbl frame=" + lblF);    lblDesc.layer().setCornerRadius(cornerRadius);    lblDesc.setClipsToBounds(1);    lblDesc.setBackgroundColor(UIColor.greenColor());    view.addSubview(lblDesc);    // 创建按钮    btn = UIButton.buttonWithType(6);    btn.setTitle_forState(''+ i, 0);    btn.titleLabel().setFont(UIFont.systemFontOfSize(50));    btn.setTag(1000);    btn.setBackgroundColor(UIColor.blueColor());    btn.addTarget_action_forControlEvents(self, 'btnClick:', 1 <<  6);    var btnX = txfF.x + txfW + margin16;    var btnY = margin;    var btnW = screenWidth - btnX - margin16;    var btnH = height - margin * 2;    btn.setFrame({x: btnX, y: btnY, width: btnW, height: btnH});    btn.layer().setCornerRadius(cornerRadius);    btn.layer().setMasksToBounds(1);    view.addSubview(btn);}
