iOS PDF editing - Combining FastPDFKit / CGPDFContext and libHaru

Question

I'm trying to add PDF Annotations onto an existing PDF file in iOS.

I understand that using FASTPDFKit / CGPDFContext, it is possible to READ ( but not EDIT ) almost all the information from an existing PDF File ( Correct me if I'm wrong ).

I also understand that using libHaru, it is a piece of cake to create annotations on a new PDF file. But libHaru does not support reading of existing PDF's.

Is there any constraint combining these 2 libraries so that I can add annotations onto an existing PDF file?

Thanks

According to me, i think we can add custom annotation using fastpdfkit...look it in fastpdfkit feature manual i.e http://mobfarm.eu/features
