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.
