Hi,
Rectangle, ellipse and ink have the type value so you can delete just rect annots by type using:

Code:

-(int)type;

in PDFObjc class.

Hi,
You should process every annots of certain page in a cycle, then check annots by type value and delete them
In your case, rect annot's type has 5 as value.

Hi,
do you mean following codes?

Code:

int pg_cnt = [doc pageCount];
int pg_num = 0;
for(pg_num = 0; pg_num < pg_cnt; pg_num++)
{
  PDFPage *pg = [doc page:pg_num];
  [pg ObjsStart];
  int annot_cnt = [page annotCount];
  int annot_num;
  for(annot_num = 0; annot_num < annot_cnt; annot_num++)
  {
    PDFAnnot *annot = [pg annotAtIndex:annot_num];
    int atype = [annot type];
    if(atype == 5 || atype == 6)//rectangle and oval
    {
      [annot removeFromPage];
      annot_num--;
      annot_cnt--;
    }
  }
  [pg Close];
}
