I did get a proof of concept working with the TextKit classes. Turns out to be possible, but more complicated and more moving parts than I would have (naively?) expected. Beyond the complexity, the main drawback to that approach is that it won't work on iOS 6, which the app in question still supports.
I'd also considered trying something similar with Core Text. I *think* that it might be possible to use a framesetter to do this, but I haven't explored that yet. I'm sure it'd be at least as complicated as the TextKit approach, though. Was really hoping there was a two-line solution that was just eluding me. On Fri, Jan 17, 2014 at 12:00 PM, T.J.
