        }
    }while (_findnext(Handle, &FileInfo) == 0);

#else
    CCLog(folderPath.c_str());

        return;
    }
    while ((dirp=readdir(dp))!=NULL)
    {

        stat(folderPath.c_str(), &buf);
        // 如果是目录
        if (S_ISDIR(buf.st_mode))

                if( (strcmp(dirp->d_name,".") != 0 ) &&(strcmp(dirp->d_name,"..") != 0)) 
                {
                    path =  folderPath + "/" + dirp->d_name;
                }
                //如果是目录，递归调用
                FindAllFile(path); 
        }
        else
        {
            // 如果是文件直接打印
            CCLog("%s/%s\n",folderPath.c_str(),dirp->d_name);
        }
    }
    CCLog("\n");
    closedir(dp);
#endif
}
记得在#include处添加如下代码:

#if (CC_TARGET_PLATFORM != CC_PLATFORM_WIN32)
    #include <dirent.h>
