You might need to dive into the supporting classes used within the
NSText ecosystem. In particular, NSLayoutManager offers this
delegate method:
- (void)layoutManager:(NSLayoutManager *)layoutManager
didCompleteLayoutForTextContainer:(NSTextContainer *)textContainer
atEnd:(BOOL)layoutFinishedFlag;
// This is sent whenever a container has been filled. This
method can be useful for paginating. The textContainer might be nil
if we have completed all layout and not all of it fit into the
existing containers. The atEnd flag indicates whether all layout is
complete.
You can grab the text view's layout manager via the -layoutManager
method. Setting your class as a delegate and then implementing the
above method to scroll to the desired location may work?
(I say "may" because I haven't poked around in this area for a long
long time.)

Oh, yes, it works! Thanks very much!
