// set current page for image
Layout* page_alert_bottom_layout = dynamic_cast<Layout*>(page_root->getChildByName("page_alert_bottom_panel"));
int count = page_alert_bottom_layout->getChildren()->count();
for (int i = count / 2; i < count; ++i)
{
UIWidget* child = dynamic_cast<UIWidget*>(page_alert_bottom_layout->getChildren()->objectAtIndex(i));
child->setVisible(false);
}
这段中，设置了4个图片，但是编辑器中好像没有index的查看，难道就按照添加到cocos studio画板中的顺序来定义的吗？
