- //string path = CCFileUtils::sharedFileUtils()->getWriteablePath()+pFileName ;
- string path = CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(pFileName.c_str());
通过fullPathFromRelativePath, 看名称,好像要你输入相对路径,其实你只需要输入Resource文件夹里的某个文件名,它就会识别这个文件的路径。所以你要传入的不是路径,而是参数,官方API文档误导人。
- const char* fullPathFromRelativePath ( const char * pszRelativePath )
- Generate the absolute path of the file.
- Parameters
- pszRelativePath The relative path of the file.
- Returns
- The absolute path of the file.
- Warning
- We only add the ResourcePath before the relative path of the file.
- Deprecated:
- Please use fullPathForFilename instead.
