UIScrollView上添加自带的UILabel没有任何问题，但是添加了CCLabelTTF后就无法滑动了。网上找了很多但是都没有解决，求大神指教！！
下面是部分代码：
noticeScrollVIew = dynamic_cast<UIScrollView*>(layer->getWidgetByName(“noticeScrollView”));
CCSize ScrollSize = noticeScrollVIew->getContentSize();
CCPoint scrollPoint = noticeScrollVIew->getPosition();
CCLabelTTF* tempTTF = CCLabelTTF::create(“i am labelttf”, “Arial”, 20);
for(unsigned int i = 0; i < 5; i++)
{
tempTTF ->setPosition(ccp(scrollPoint.x + ScrollSize.width/1.6, scrollPoint.y + ScrollSize.height*(1.4-0.2*i)));
}
noticeScrollVIew->CCNode::addChild(tempTTF , tempTTF ->getZOrder(), tempTTF ->getTag());
