Thanks, there is no immediate need to override so I will try calling it.
So would this work?…
CGFloat spacing = 5.0f;
NSMutablePargagraphStyle *paragraphStyle;
[paragraphStyle setLineSpacing:spacing];
[paragraphStyle setMinimumLineHeight:spacing];
[paragraphStyle setMaximumLineHeight:spacing];
[textView setDefaultParagraphStyle:paragraphStyle];

That's the point. You may _want_ to change the paragraph style's properties,
but you can't. Casting the parameter doesn't turn an immutable object into a
mutable one.
If you really want to substitute a paragraph style of your own (and please
comment on the suggestions that you may not want to), make a mutableCopy, set
that up as you wish, and pass it up to super.
You may be misconceiving the need to subclass in Cocoa. Subclassing is rare.
Most modifications to object behaviors are done through delegates and property
setters; Cocoa provides a lot of them. That's why you're getting told to _call_
setDefaultParagraphStyle:, not _override_ it.
If you explained why you feel you must override, we might be better able to
help you.
