ccs.UIScrollView.extend is not a Function?

cocos2d-x JavaScript
1

With Javascript/Web project this code will work:

var ui_sprites_ScrollView = ccs.UIScrollView.extend({

…………

});

ui_sprites_ScrollView.create = function () {
var uiScrollView = new ui_sprites_ScrollView();
if (uiScrollView && uiScrollView.init()) {
return uiScrollView;
}
return null;
};

How can one extends the action interval class for Cocos2d-x ios/JS project?
Because in ios Debug error gives:

2013-12-31 15:41:22.331 JS ListView.js:2:TypeError: ccs.UIScrollView.extend is not a function

You can try：

var ui_sprites_ScrollView = cc.Layer.extend({
    uiScrollView:null,
    init:function(){
        uiScrollView = ccs.UIScrollView.create(); 
    }
});
