how to get all Annotation present in current page of pdf in IOS

I have following query regarding the functionality in PDFNet SDK for iOS (Swift )

I drawn some annotations(Like line, circle,Arrow etc ) . After drawing these annotations, i am saving the drawn annotation data by using “doc.SaveToFile(“FileName.pdf”, flags: e_ptlinearized.rawValue)” method.

But i need to get each and Every annotation value. May i know is there any possibility to get it ?

But i need to get each and Every annotation value.

Could you please elaborate on your objective? What are you trying to accomplish? What do you mean by “value”?
