我正在开发Android和IOS的跨平台应用程序。当我尝试获取位于资产文件夹中的.json文件时，如下所示
const char * genrefile = CCFileUtils::sharedFileUtils()->fullPathFromRelativePath("genres.json");
CCLog( " %s ---------- genrefile ---------", genrefile);
size_t size;
unsigned char * charbuffer = CCFileUtils::sharedFileUtils()->getFileData(genrefile, "rb", 0);
控件来自应用程序，具有以下堆栈跟踪

getFileData(...)类中的 CCFileUtils方法可以很好地获取图像但不能与其他文件一起使用。非常感谢帮助。
答案 0 :(得分：1)
试试这个：
unsigned long bufferSize = 0;
unsigned char * charbuffer = CCFileUtils::sharedFileUtils()->getFileData(genrefile, "rb", &bufferSize );
