On a related note, what's the easiest way to wire my own subclass of NSTextStorage into a basic NSDocument based app (based on the write a text editor in 15 minutes tutorial)? Since the NSTextView that is instantiated in Interface Builder creates its NSTextStorage under the covers, I can't figure out the best way to intervene. Do I have to not create the NSTextView in IB and instead create it programatically and add it to the scroll view at runtime?

So it turns out the best way to do this appears to be to create a CustomView in IB and wrap it in a NSScrollView. Then set the class of that CustomView to my own subclass of NSTextView that overrides initWithFrame to instantiate the NSTextStorage subclass I want (along with the NSLayoutManager and NSTextContainer) and then call initWithFrame:textContainer. It's not sufficient to simply set a custom class on the NSTextView you get from the palette since it will be serialized and initialized via initWithCoder rather than initWithFrame which doesn't give you a chance to call initWithFrame:textContainer. At least that's my current understanding. From there it was just a matter of jumping through a few hoops in awakeFromNib to get my text view properly wired together with the scroll view and it seems to be working. Thanks to the folks on #macdev for their help.
