Hello Leonardo,
You are correct that your dirty workaround is not very good, since it won't handle many cases. Since the typesetter inserts a hyphen glyph into the glyph stream whenever hyphenation occurs, perhaps you should check for the presence of that glyph at the end of each line fragment using -[NSLayoutManager glyphAtIndex:].
Another potential approach: you might subclass the typesetter and override -[NSTypesetter shouldBreakLineByHyphenatingBeforeCharacterAtIndex:] and record the instances where super returns YES.
I hope that helps,
