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.

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.
