osx - Get correct NSRect in NSTextView when image insert -

-

i use [nstextview firstrectforcharacterrange:actualrange:] , [nslayoutmanager boundingrectforglyphrange:intextcontainer:] cursor rect, works right when pure text in nstextview.

but when insert image text view, [nstextview firstrectforcharacterrange:actualrange:] return wrong result(nsrectzero), , [nslayoutmanager boundingrectforglyphrange:intextcontainer:] return right value in textview convert superview wrong.

only when image bigger textview bounds happen.

anyone knows how resolve that?
