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.
