接上一篇，CCMenu当作ScrollView的Item可能满足不了我现在的需求。
Item中先有个background框，分选中状态...还有个background，还有个CCArmature....
自定义一个类StaticItem继承自CCSprite和CCTouchDelegate
StaticItem.h

StaticItem.cpp

以上红色部分是我遇到问题的部分，不getParent的话，你会发现draw描框永远在那里不跟着动。坐标是错的。
isPointIn方法中也是同样的道理，如果不的话，你会发现点到的永远是那一个item。
接着上代码

试之，在Item上点击，拖动，都是对的：）
----------------------------
补充：在真机上测试，对于判断是点击还是拖动，不是很理想，大多数情况都被判断成了拖动。
我们给他一个误差值，修改方法如下
void StaticItem::ccTouchEnded(CCTouch *pTouch, CCEvent *pEvent){ CCPoint p1 = pTouch->getLocation(); CCPoint p2 = pTouch->getStartLocation(); if(abs(p1.x-p2.x)<=10&&abs(p1.y-p2.y)<=10){ CCLog("StaticItem::ccTouchEnded 点击%d",this->getTag()); }else{ CCLog("StaticItem::ccTouchEnded 拖动%d",this->getTag()); } }
