How would I set the Line Height or Line Spacing in an
- (void)setDefaultParagraphStyle:(NSParagraphStyle *)paragraphStyle method in your NSTextView.
Documentation on NSParagraphStyle
Documentation on NSMutableParagraphStyle
There is a
setLineSpacing: method in NSMutableParagraphStyle. There are also methods relating to line height, the methods under "Setting Other Style Information" in the NSMutableParagraphStyle documentation should prove useful.
I think that's what you're looking for.
