关于如何使用cocos2dx CCControlButton 按钮事件，分享代码如下，希望对大家有所帮助。

cocos2dx CCControlButton 按钮事件代码： 


bool HelloWorld::init()
{ //////////////////////////////  // 1. super init first if ( !CCLayer::init() )
    { return false;
    }
    CCLabelTTF * label = CCLabelTTF::create("为选中文字", "MarkerFelt",25);
    CCControlButton * button = CCControlButton ::create(label,CCScale9Sprite::create("button.png"));
    button->setPosition(ccp(240, 170)); // 按钮选中后背景图响应的状态 button->setTitleColorForState(ccc3(255, 0, 0), CCControlStateHighlighted); // 按钮选中后文字响应的状态 button->setTitleForState(CCString::create("选中文字"), CCControlStateHighlighted);
    
    addChild(button); // 按下按钮事件回调 button->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDownAction), CCControlEventTouchDown); // 按钮在其内部拾起事件回调 button->addTargetWithActionForControlEvents(this , cccontrol_selector( HelloWorld::touchUpInsideAction), CCControlEventTouchDragEnter); // 按钮在其外部拾起事件回调 button->addTargetWithActionForControlEvents(this,cccontrol_selector(HelloWorld::touchUpOutsideAction), CCControlEventTouchDragOutside); // 用于显示按钮的状态 CCLabelTTF * la = CCLabelTTF ::create(" ", "MarkerFelt",20);
    la->setColor(ccc3(255, 0, 0));
    la->setPosition(ccp(240, 220));
    addChild(la,0,923); return true;
} // 按下按钮事件回调 void HelloWorld:: touchDownAction(CCObject * sender , CCControlEvent * controlEvent)
{
    CCLabelTTF * label = (CCLabelTTF*) this ->getChildByTag(923);
    label->setString(CCString::createWithFormat("按下")->getCString());

} // 按钮在其内部抬起事件回调 void HelloWorld::touchUpInsideAction(CCObject * sender , CCControlEvent * controlEvent)
{
    CCLabelTTF * label = (CCLabelTTF*) this ->getChildByTag(923);
    label->setString(CCString::createWithFormat("内部抬起")->getCString());
} // 按钮在其外部抬起事件回调 void HelloWorld::touchUpOutsideAction(CCObject * sender , CCControlEvent * controlEvent)
{
    CCLabelTTF * label = (CCLabelTTF*) this ->getChildByTag(923);
    label->setString(CCString::createWithFormat("外部抬起")->getCString());

}
复制代码

。需要声明的
