Hi team,
which is the correct way to retrieve the page number from a PDFPage and a PDFDoc instance?

Is the snippet below correct?
int currentPage;
PDFDoc *currentDoc = ... //Current doc instance
PDFPage *page = ... //page instance
for (int i = 0; i < [currentDoc pageCount]; i++) {
    if ([page advanceGetRef] == [[currentDoc page:i] advanceGetRef]) {
        currentPage = i;
        break;
    }
}

Thanks in advance.

no direct way to know page NO from PDFPage object.
if you need this feature, you can:
1.add private attribute to PDFPage. like "int pageno"
2.set this attribute in method [PDFDoc page].
then you can using [page pageno] to known page index.

but i don't recommand you to do this.
because, after create or delete page, the pageno may changes.
