The documentation seems to be in conflict on this point. -[NSAttributedString string] says the following: > This method doesn’t strip out attachment characters; use NSText's string > method to extract just the linguistically significant characters. > > For performance reasons, this method returns the current backing store of the > attributed string object.

But -[NSText string] also says this: > For performance reasons, this method returns the current backing store of the > text object.

Which implies that -[NSText string] is implemented to just return [[self textStorage] string], which would defy -[NSAttributedString string]'s documentation. I think NSAttributedString is in error here; will file a doc bug soon. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
