Hi, Sorry for being over a week late to this thread, but I'm the guy who was trying to get hidden text to work before, in the thread mentioned earlier (Martin kindly pointed me in this direction). I'm not sure why the test code archives on my site weren't decompressing, but they probably just got corrupted when I moved between servers earlier in the year. Anyway, for what it's worth, I have re-uploaded the code I had for this here:
http://www.literatureandlatte.com/misc/HiddenTextArchives.zip This zip file contains several zip files of different stages of the test project, as I haven't had chance to go through them, and a quick glance suggests that you may need to hook up a couple of actions in IB to be able to test them properly (not sure how they became unhooked). To be honest I abandoned trying to hide glyphs at all; I wanted to do it to hide inline comments and footnotes in my app, the same as "hidden text" works in Word, but as far as I can see the OS X text system just isn't built for this. Although the code in those archives works to an extent, exceptions still get thrown in certain circumstances because the text system just expects certain things to be there and there seems to be no way to convince it otherwise. I used one of my technical support tickets on this, and had some excellent help from Aki Inoue and another Apple developer, and the methods in the zipped projects are mostly Aki's (so thanks to them for going the extra mile in trying to help me!). But in the end, even they couldn't help me find a suitable non-crashing, non-exception-throwing solution for this, and I figured that if even the OS X text gurus at Apple couldn't come up with a solution, then I had little chance of finding one on my own. So if you do make any progress with it, I'd love to know how you get on. (If you would like to see any of the correspondence on this with the various technical issues invovled, just e-mail me off-list and I can dig it out for you.)
