In my iOS app I use custom fonts, dynamically loaded from files.

To use them in code, I need to know loaded fonts' families. So, is there any way to do it?

*UPDATE:*

I can't somehow hardcode font families, cause my app loads it from server. Of course, there is a way to pass font families in server response, but for now I'm looking for a better version that doesn't influence the server (doesn't need to change it).
