我正在开发适用于 Android 和 IOS 的跨平台应用程序。当我尝试获取位于 Assets 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);

CCFileUtils 类中的 getFileData(...) 方法可以很好地获取图像，但不能用于其他文件。非常感谢帮助。
最佳答案
试试这个:
unsigned long bufferSize = 0;
unsigned char * charbuffer = CCFileUtils::sharedFileUtils()->getFileData(genrefile, "rb", &bufferSize );
关于android - Cocos2dx Android : getFileData failed to get . 来自 Assets 的json文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13605092/
