emoji

I'm trying to implement my own emoji icon keyboard and have some problems. I'm trying to draw emoji icons at the same size as on native iOS emoji keyboard, but when doing simple drawing (standard unicode characters like "\ue415") icons always appear at original size. When trying to increase the font - emoji icons stay of the same size. When applying CGAffineTransform for scaling - drawn icons are bigger, but pixelated and blurred. How should I go about drawing emoji icons bigger, but sharper?
