添加Touch回调报错

Cocos2d-x
#1

报错如下：
0x10365344 (libcocos2d.dll) (9sprite.exe 中)处的第一机会异常: 0xC0000005: 写入位置 0x00000368 时发生访问冲突。
0x10365344 (libcocos2d.dll) (9sprite.exe 中)处有未经处理的异常: 0xC0000005: 写入位置 0x00000368 时发生访问冲突。

init函数修改如下

bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }
    
    //auto UI = cocostudio::GUIReader::getInstance()->widgetFromBinaryFile("MainScene.csb");
    //UI->setPosition(Point(200, 200));
    Node* main = CSLoader::createNode("MainScene.csb");
    this->addChild(main);

    dProgress = static_cast(main->getChildByName("dProgress"));
    dProgress->addTouchEventListener(this, toucheventselector(HelloWorld::onClick));
    
    return true;
}


```


Touch回调如下：

void HelloWorld::onClick(Ref*, TouchEventType type) {
    switch (type) {
    case TouchEventType::TOUCH_EVENT_MOVED:
        dProgress->setPercent(dProgress->getPercent() + 1);
        break;
    }
}


```


头文件内容如下：

#ifndef __HELLOWORLD_SCENE_H__
#define __HELLOWORLD_SCENE_H__

#include "cocos2d.h"
#include "ui\CocosGUI.h"
#include "editor-support\cocostudio\CocoStudio.h"
using namespace cocos2d::ui;
using namespace cocostudio;

class HelloWorld : public cocos2d::Layer
{
public:
    // there's no 'id' in cpp, so we recommend returning the class instance pointer
    static cocos2d::Scene* createScene();

    // Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone
    virtual bool init();
    
    // a selector callback
    void menuCloseCallback(cocos2d::Ref* pSender);

    void onClick(Ref*, TouchEventType type);
    
    LoadingBar* dProgress;
    // implement the "static create()" method manually
    CREATE_FUNC(HelloWorld);
};

#endif // __HELLOWORLD_SCENE_H__

求大大帮帮忙啊！:12:
