in last version, you can use [PDFAnnot export] to export annotation data, like:

int data_size = [PDFAnnot export:NULL :0];
unsigned char *data = (unsigned char *)malloc(data_size);
[PDFAnnot export:data :data_size];
//todo save data and data_size to your DB or storage.
free(data);//free memory.

some annotation not support export, supported annotation type shall be:
ink/line/square/circle/text note/free text/polygon/polyline
