使用VS类向导添加ScreenAdapter，在Num2048项目上右键选择“添加”—>“类”，然后将生成的两个文件拖放到Classes文件夹中

                                                  

在头文件中声明几个静态方法如下：

#ifndef __ScreenAdapter_H__

#define __ScreenAdapter_H__

#include "cocos2d.h"

class ScreenAdapter

{

public:

    /*ScreenAdapter(void);

    ~ScreenAdapter(void);*/

    static int GetFontSize(int number);

    static int GetDefaultFontSize();

    static cocos2d::ccColor3B GetColor(int number);

    static const char* GetString(int number);

};

#endif

最后在ScreenAdapter.cpp文件中定义方法

#include "ScreenAdapter.h"

//

//ScreenAdapter::ScreenAdapter(void)

//{

//}

//

//

//ScreenAdapter::~ScreenAdapter(void)

//{

//}

//默认字体大小，这个还需要修改

int ScreenAdapter::GetDefaultFontSize(){

    return 40;

}

//根据数值获取字体大小

int ScreenAdapter::GetFontSize(int number)

{

    int fontSize = 0;

    if (number >= 0)

        fontSize = 100;

    if (number >= 16)

        fontSize = 90;

    if(number >= 128)

        fontSize = 60;

    if(number >= 1024)

        fontSize = 40;

    return fontSize;

 }

//根据数值获取背景颜色

cocos2d::ccColor3B ScreenAdapter::GetColor(int number){

    if(number == 0)

        return cocos2d::ccc3(200,190,180);

    if (number == 2)

        return cocos2d::ccc3(240,230,220);

    if (number == 4)

        return cocos2d::ccc3(240,220,200);

    if (number == 8)

        return cocos2d::ccc3(240,180,120);

    if (number == 16)

        return cocos2d::ccc3(240,140,90);

    if (number == 32)

        return cocos2d::ccc3(240,120,90);

    if (number == 64)

        return cocos2d::ccc3(240,90,60);

    if (number == 128)

        return cocos2d::ccc3(240,90,60);

    if (number == 256)

        return cocos2d::ccc3(240,200,70);

    if (number == 512)

        return cocos2d::ccc3(240,200,70);

    if (number == 1024)

        return cocos2d::ccc3(0,130,0);

    if (number == 2048)

        return cocos2d::ccc3(0,130,0);

}

//获取数值的字符串

const char* ScreenAdapter::GetString(int number)

{

    if(number>0)

        return cocos2d::CCString::createWithFormat("%i",number)->getCString();

    else

        return "";

}
