cocos2dx之彩色编辑输入框的设计(3)

然后是触摸函数的实现：

bool ColorEdit::onTouchBegan(Touch* touch, Event* pEvent)
{
	auto touchPoint = touch->getLocation();
	//如果是全屏显示类型，并且键盘已弹出
	if (m_editLocation == Location_Screen && m_isKeyShow)
	{
		auto key_upEdit = (Scale9Sprite *)m_pTarget->getChildByTag(101);
		//如果点击除了顶层输入框和键盘的其他地方，则键盘消失
		if (!m_keyBg->getBoundingBox().containsPoint(touchPoint) && 
			!key_upEdit->getBoundingBox().containsPoint(touchPoint))
		{
			this->moveAction(false);
			return true;
		}
		return false;
	}

	//将触摸点转为在当前子层下的坐标
	touchPoint = this->convertToNodeSpace(touchPoint);
	if (!m_pEditBg->getBoundingBox().containsPoint(touchPoint))
	{
		if (m_isKeyShow)
		{
			if (!m_keyBg->getBoundingBox().containsPoint(Vec2(touch->getLocation().x,
					touch->getLocation().y - (m_editLocation == Location_Down ? 1 : 0) * m_keyBg->getContentSize().height)))
			{
				this->moveAction(false);
			}
		} 
		return false;
	}
	//如果点击了输入框，并且键盘还未弹出
	if (!m_isKeyShow)
	{
		this->updateText();
		this->moveAction(true);
	} 

	return true;
}

这里有个要注意的地方：

if (!m_keyBg->getBoundingBox().containsPoint(Vec2(touch->getLocation().x,
					touch->getLocation().y - (m_editLocation == Location_Down ? 1 : 0) * m_keyBg->getContentSize().height)))
			{
				this->moveAction(false);
			}

当键盘的弹出方式是效果图第二张时，因为背景图向上移动了一段距离，touch->getLocation()的y坐标要做一下修改，否则getBoundingBox的判断不正确。

再来看看对于键盘点击的响应函数：

void ColorEdit::onNumBtnCallback(Ref * obj)
{
	int tag = ((Node *)obj)->getTag();
	//点击按钮的简单动画
	((MenuItemSprite *)obj)->runAction(Sequence::create(ScaleTo::create(0.1,10 / 8.0),ScaleTo::create(0.1,1),NULL));
	
	char temp[3];
	sprintf(temp,%d,tag);
	m_text += temp;
	//更新内容
	this->updateText();

	log(keyboard------->%d,tag);
}

void ColorEdit::onFunBtnCallback(Ref * obj)
{
	((MenuItemSprite *)obj)->runAction(Sequence::create(ScaleTo::create(0.1,10 / 8.0),ScaleTo::create(0.1,1),NULL));

	if (((Node *)obj)->getTag() == Key_Sure)
	{
		this->moveAction(false);
	}
	else
	{
		auto n = m_text.size();
		if (n > 0)
		{
			m_text = m_text.substr(0,n - 1);
		}
		this->updateText();
	}
}

接着是键盘的出现与消失：

void ColorEdit::moveAction(bool isShow)
{
	if (m_editLocation == Location_Screen)
	{
		auto keyLayer = (LayerColor *)m_pTarget->getChildByTag(100);
		auto key_upEdit = (Scale9Sprite *)m_pTarget->getChildByTag(101);

		keyLayer->setVisible(isShow);
		key_upEdit->runAction(MoveBy::create(0.35,Vec2(0,(isShow ? -1 : 1) * key_upEdit->getContentSize().height)));
		m_keyBg->runAction(MoveBy::create(0.35,Vec2(0,(isShow ? 1 : -1) * m_keyBg->getContentSize().height)));
	}
	else if (m_editLocation == Location_Down)
	{
		Director::getInstance()->getRunningScene()->runAction(MoveBy::create(0.35,Vec2(0,(isShow ? 1 : -1) * m_keyBg->getContentSize().height)));
	}
	else if (m_editLocation == Location_Nature)
	{
		m_keyBg->runAction(MoveBy::create(0.35,Vec2(0,(isShow ? 1 : -1) * m_keyBg->getContentSize().height)));
	}

	m_isKeyShow = isShow;
	if (!isShow)
	{
		m_text = ;
	}
}
