editbox输入数字以后会变成一块黑 如下图：
代码
Scale9Sprite *s9sprite = Scale9Sprite::create("backg.png"); m_InputBox = EditBox::create(CCSizeMake(110, 50), s9sprite); m_InputBox->setAnchorPoint(ccp(0.5f, 0.5f)); m_InputBox->setPosition(ccp(290, size.height - 100)); m_InputBox->setText("1.0"); m_InputBox->setMaxLength(10); m_InputBox->setOpacity(200); m_InputBox->setFontSize(6); m_InputBox->setInputMode(EditBox::InputMode::DECIMAL); m_InputBox->setReturnType(EditBox::KeyboardReturnType::DONE); this->addChild(m_InputBox, 10);
啊
