Is there a way to teach tesseract for iOS a new font?

[Pyroclastic]

I'm using the tesseract API on an iOS device using https://github.com/nolanbrown/Tesseract-iPhone-Demo build of the tesseract lib.

The app recognizes one font, but I need to get it to recognize one more font (just numbers). Is there a way to teach it to do this? I have Googled around, but only seen tutorials (google code site) on where people use command line to achieve this.

Could someone please tell me the best approach to take in order to achieve this? Would I need to recompile tesseract for iOS? How would I do this? I'm fairly new to OCR and tesseract.

Thanks
