Create PDF annotations using quartz (iOS)

Question

Could anyone write custom annotations in an existing PDF format using Quartz? I made a PDF file using CGPDFDocumentRef etc., it works fine now :) And I successfully read Annots dict using

    if(!CGPDFDictionaryGetArray(pageDictionary, "Annots", &outputArray)) { ....

But I can’t lower my head, how to write new annotations.

Hmmm, nobody? it cannot be impossible ...: (
