How can I use iOS6 fonts in iOS5

Question

My app uses the lovely Avenir font which is built in to iOS6 but not iOS5. How can I get it onto iOS5? I know I can fall back to a different font on iOS5 (eg just use System font) but I don't want to do that. Can I build the Avenir font into my app some how?

Answer 1

No and Yes, you could just supply the font with your app. But you will need to buy a distribution license for the font, this will be very costly.

Your best option is to fall back to an other font on iOS5 or just not support iOS5.
