In the end I subclased the NSTextField class and overrid the

Well, what you're doing is using only explicit line breaks, rather
than allowing wrapping, and you're taking into account only \n as a
line separator, rather than handling all of the line and paragraph
break characters. What you're doing will work, more or less, but
it's not sufficiently general to be a real solution.
Yes. It certainly isn't a real/generic solution. In this case I
actually wanted the lines to clip, rather than wrap if the user hadn't
explicitly sorted them out previously in the application.
I missed the initial question, but in general line heights are
controlled by an NSParagraphStyle, which is used as the value of the
NSParagraphStyleAttributeName attribute. This is the same object
that controls most paragraph-level styling, including line breaking,
alignment, etc.
Ah, cool, thanks. Not sure why I didn't find that with Google!
