    //get first page

    PDFPage *page1 = [m_doc page:0];

    [page1 objsStart];

    

    //get last added annotation

    PDFAnnot *annot = [page1 annotAtIndex:([page1 annotCount] - 1)];

    

    //save annotation data and export

    PDF_RECT rect;

    [annot getRect:&rect];

    

    unsigned char buf[1024];

    [annot export:buf :sizeof(buf)];

    

    //get second page

    PDFPage *page2 = [m_doc page:1];

    

    //import annotation to the second page

    NSData *data = [NSData dataWithBytes:buf length:sizeof(buf)];

 

    [page2 importAnnot:&rect :[data bytes] :data.length];

 

You can change the buf size based on your needs.
