1. 修改：CCTextureCache.h
    1.)添加：VolatileTexture::addDataTexture(CCTexture2D *tt,const void* data,CCTexture2DPixelFormat pixelFormat,unsigned int pixelsWide,unsigned int pixelsHigh,const CCSize& c             ontentSize)
    让其增加数据备份功能：

void VolatileTexture::addDataTexture(CCTexture2D *tt,const void* data,CCTexture2DPixelFormat pixelFormat,unsigned int pixelsWide,unsigned int pixelsHigh,const CCSize& contentSize)
                {
                    if (isReloading)
                        return;
                
                    VolatileTexture *vt = 0;
                    std::list<VolatileTexture *>::iterator i = textures.begin();
                    while( i != textures.end() )
                    {
                        VolatileTexture *v = *i++;
                        if (v->texture == tt) {
                            vt = v;
                            break;
                        }
                    }
                
                    if (!vt)
                        vt = new VolatileTexture(tt);
                
                    vt->m_eCashedImageType = kImageData;
                    vt->m_PixelFormat = pixelFormat;
                    vt->m_TextureSize = contentSize;
                    if(vt->m_pTextureData)
                    {
                        delete[] vt->m_pTextureData;
                        vt->m_pTextureData = 0;
                    }
                    switch(pixelFormat)
                    {
                    case kCCTexture2DPixelFormat_RGBA8888:
                    case kCCTexture2DPixelFormat_RGBA4444:
                    case kCCTexture2DPixelFormat_RGB5A1:
                    case kCCTexture2DPixelFormat_RGB565:
                    case kCCTexture2DPixelFormat_A8:
                        vt->m_pTextureData = new char[pixelsWide * pixelsHigh * 4];
                        memcpy(vt->m_pTextureData,data,pixelsWide * pixelsHigh * 4);
                        break;
                    case kCCTexture2DPixelFormat_RGB888:
                        vt->m_pTextureData = new char[pixelsWide * pixelsHigh * 3];
                        memccpy(vt->m_pTextureData,data,pixelsWide * pixelsHigh * 3);
                        break;
                    }
                    
                }

　　2.)CCTextureCache.cpp 
　　

VolatileTexture::~VolatileTexture()
                {
                    //Ambition 添加
                    if(this->m_pTextureData)
                    {
                        delete [] this->m_pTextureData;
                    }
                    textures.remove(this);
                }

2.修改：CCTexture2D.h

  1.)cpp文件里 initWithData(const void *data, CCTexture2DPixelFormat pixelFormat, unsigned int pixelsWide, unsigned int pixelsHigh, const CCSize& contentSize)

   

//Ambition 添加
            #if CC_ENABLE_CACHE_TEXTTURE_DATA
                VolatileTexture::addDataTexture(this,data,pixelFormat,pixelsWide,pixelsHigh,contentSize);
            #endif
