Re: Tracking text attribute ranges in NSTextStorage

Many thanks for your reply, that is indeed really
helpful. I found the part in the docs about cycling
through an attributed string by attributes in the way
that you are doing, and that seems exactly what I want
to do.

What I was going to do was use a NotesManager
controller layer to monitor
NSTextStorageDidProcessEditingNotifications and update
all the note ranges there, but I think your solution
of subclassing NSTextStorage is a more efficent option
and I will probably take that route.

Many thanks for the help, I think that solves my
problem, much appreciated.
All the best,
Keith
