【转】CCScale9Sprite和CCControlButton

转自：http://blog.csdn.net/nat_myron/article/details/12975145

在2dx下用到了android下的.9.png图片，下面是原图

查了一下2dx里有CCScale9Sprite，直接贴上背景图，毫无问题，

CCSize bgRect = CCSizeMake(size.width,size.height/3);
CCScale9Sprite *background   = CCScale9Sprite::create("dialog_bg.png");
background->setContentSize(bgRect);
background->setPosition(ccp(bgRect.width/2,-bgRect.height/2));
this->addChild(background,5);

然后按钮里也需要用到这个素材图，拉伸图片到我们需要的，用到了CCControlButton

CCLabelTTF *title1 = CCLabelTTF::create("拍照", "Marker Felt", 30);
CCControlButton* btn_takephoto = CCControlButton::create(title1,CCScale9Sprite::create("dialog_normal.png"));
 /* 设置按钮按下时的图片 */ 
btn_takephoto->setBackgroundSpriteForState(CCScale9Sprite::create("dialog_pressed.png"), CCControlStateSelected);
btn_takephoto->setPosition(ccp(bgRect.width/2,bgRect.height/5*4));
btn_takephoto->setPreferredSize(btnRect);
btn_takephoto->addTargetWithActionForControlEvents(this, cccontrol_selector(DialogPhoto::MenuItemCallback), CCControlEventTouchUpInside);
background->addChild(btn_takephoto);

当然也可以用CCMenuItemSprite

CCScale9Sprite* sp1 = CCScale9Sprite::create("dialog_normal.png");
sp1->setContentSize(btnRect);
CCScale9Sprite* sp2 = CCScale9Sprite::create("dialog_pressed.png");
sp2->setContentSize(btnRect);
CCMenuItemSprite* btn_takephoto = CCMenuItemSprite::create(sp1,sp2,this,menu_selector(DialogShare::MenuItemCallback));
btn_takephoto->setPosition(ccp(bgRect.width/2,bgRect.height/5*4));
btn_takephoto->setTag(DialogTakePhoto);
CCLabelTTF* pLabel1 = CCLabelTTF::create("拍照", "Arial", 20);
pLabel1->setColor(ccc3(0, 0, 0));
pLabel1->setPosition(ccp(btnRect.width/2,btnRect.height/2));
btn_takephoto->addChild(pLabel1);

m_pMenu = CCMenu::create(btn_takephoto,btn_photoalbum,btn_cancel, NULL);
m_pMenu->setPosition(CCPointZero);
background->addChild(m_pMenu);

下面就是我们所需的效果

这里用到了对话框的思想，点击按钮之后从底部弹出菜单，下面贴出全部代码

#pragma once

#include "cocos2d.h"
#include "HelloWorldScene.h"
#include "cocos-ext.h"
USING_NS_CC_EXT;
USING_NS_CC;

class DialogShare: public CCLayerColor
{
    // 模态对话框菜单
    CCMenu *m_pMenu;
    // 记录菜单点击
    bool m_bTouchedMenu;
public:
    DialogShare();
    ~DialogShare();
    static cocos2d::CCScene* scene();
    virtual bool init();
    // 初始化对话框内容
    void initDialog();
    
    CREATE_FUNC(DialogShare);
    
    void onEnter();
    void onExit();
	virtual bool ccTouchBegan(CCTouch *pTouch, CCEvent *pEvent);
	virtual void ccTouchMoved(CCTouch *pTouch, CCEvent *pEvent);
	virtual void ccTouchEnded(CCTouch *pTouch, CCEvent *pEvent);
	virtual void ccTouchCancelled(CCTouch *pTouch, CCEvent *pEvent);
    
    void MenuItemCallback(CCObject *pSender);
};
