CCControlSlider弹窗

CCControlSlider弹窗原理跟TableView一样的，不过有点小问题，CCControlSlider的ccTouchBegan是protect的，无法被调用，于是得再包装一下

class MyCCControlSlider : public CCControlSlider

{
public:
virtual bool ccTouchBegan(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
CCControlSlider::ccTouchBegan(pTouch, pEvent);
}
virtual void ccTouchMoved(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
CCControlSlider::ccTouchMoved(pTouch, pEvent);
}
virtual void ccTouchEnded(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
CCControlSlider::ccTouchEnded(pTouch, pEvent);
}

};

因为create没有重写，因此在创建的时候

MyCCControlSlider* _slider = static_cast<MyCCControlSlider*>(CCControlSlider::create("sliderTrack.png","sliderProgress.png" ,"sliderThumb.png"));

之后再在 带屏蔽层的ccTouchXXX里面加上

_slider->ccTouch XXX就可以正常的工作了，小伙伴们赶紧试试
