//新手求助，X3.4怎么获取cocos2.15的按钮组件？好实现Touch,卡一天了。。能帮个忙或找个DEMO不，TESTS里都是手写的Btn，论坛里有回调的那种方法也不行，找老源码都是.ExportJson的老版，cocos2.15是.CSB文件，求助
auto UI1 = CSLoader::createNode("LittleRunnerUI.csb");
addChild(UI1);
auto jumpBtn = (Button*)Helper::seekWidgetByName( UI1, "JumpBtn");//ui1不是widget不能获取
//jumpBtn->setPosition(Vec2(11, 11));
jumpBtn->addTouchEventListener(this, toucheventselector(TollgateScene::jumpEvent));
