cocos2d-x 3.2 Button点击事件里调用移除当前层报错

http://www.th7.cn/program/ios/201408/271227.shtml

诡异的错误，点击关闭按钮，居然进入

void Widget::onTouchEnded(Touch *touch, Event *unusedEvent)
两次，第二次报错。

修改下这个函数：调换一下位置就行了

void Widget::releaseUpEvent()
{if (_touchEventListener && _touchEventSelector){(_touchEventListener->*_touchEventSelector)(this, TOUCH_EVENT_ENDED);}if (_touchEventCallback) {_touchEventCallback(this, TouchEventType::ENDED);}
}

 

ShopPanel类：

#include "ShopPanel.h"
#include "ui/CocosGUI.h"
#include "Global.h"using namespace CocosDenshion;
using namespace cocos2d;
using namespace ui;ShopPanel::ShopPanel()
{}
ShopPanel::~ShopPanel()
{}
bool ShopPanel::init()
{if (!Node::init()){return false;}auto s = Director::getInstance()->getWinSize();Layout* la = static_cast<Layout*>(cocostudio::GUIReader::getInstance()->widgetFromJsonFile("ui/shopPanel.json"));this->addChild(la);closeBtn = static_cast<Button*>(Helper::seekWidgetByName(la, "closeBtn"));closeBtn->addTouchEventListener(CC_CALLBACK_2(ShopPanel::closeEvent, this));return true;
}
void ShopPanel::open(Node* parent)
{if (parent != nullptr && !isopen){isopen = true;parent->addChild(this);this->setScale(0);ScaleTo *scale1 = ScaleTo::create(0.2f, 1.0f);EaseBackOut *tween = EaseBackOut::create(scale1);this->runAction(tween);}
}
void ShopPanel::close()
{if (isopen){isopen = false;this->removeFromParent();}
}
void ShopPanel::closeEvent(Ref *pSender, Widget::TouchEventType type)
{switch (type){case Widget::TouchEventType::ENDED:this->close();break;default:break;}
}
void ShopPanel::onExit()
{Node::onExit();
}

调用打开函数：

void FirstScene::openShop(Ref *pSender, Widget::TouchEventType type)
{switch (type){case Widget::TouchEventType::ENDED:ShopPanel* shop = ShopPanel::create();shop->open(this);break;}
}
