#1

向UIButton控件添加一个子节点ImageView控件 改变UIButton透明度子节点透明度不随着改变。

    UIButton *pLiveButton = UIButton::create();
pLiveButton->loadTextureNormal("Defiance01_2.png",UI_TEX_TYPE_PLIST);
pLiveButton->loadTexturePressed("Defiance01_2.png",UI_TEX_TYPE_PLIST);
pLiveButton->setPosition(ccp(608.f,193.f));
pLiveButton->setOpacity(0);
m_pPanel->addChild(pLiveButton,enZorderFront,enTagLiveButton);

ImageView *pImageLive = ImageView::create();
pImageLive->setPosition(ccp(0.f,-34.f));
pImageLive->setOpacity(0);
pLiveButton->addChild(pImageLive);

    pLiveButton->runAction(CCFadeTo::create(0.2f,255));
