I have seen an application named "PDFPenPro" which will edit PDFs.
Can anybody give some light on this, how this application stores
data internally in .pdf.
Knowing nothing of the inner workings of PDFPenPro, I can't help you
there. The PDF spec however lays out how the various pieces of a PDF
fit together — it seems likely that PDFPenPro is simply following the
PDF spec.
A good place to start in Cocoa is to use PDF Kit. In particular the
Leopard version of PDF Kit which allows you to create and edit
Annotations, Outlines, etc. There is enough sample code at ADC (and
one more bit in the Developer/Examples/Quartz/PDFKit folder on Tiger).
