    CFURLRef resourcesURL = CFBundleCopyResourcesDirectoryURL(mainBundle);
    char path[512];
    if (!CFURLGetFileSystemRepresentation(resourcesURL, TRUE, (UInt8*)path, 512))
    {
        // error!
        std::cout << "Path not found!" << std::endl;
    }
    CFRelease(resourcesURL);
    return std::string(path);
