CoreText Framework: Since iOS 3.2 a very very good rendering engine But that's it Can directly layout and render NSAttributesStrings However, there is no user interaction No text selection, no text input, no spell checking, no replacements, no highlights,.... no no no no no. Just rendering. And quite a bit of work to make it fast on old devices with long texts.
