I have a PDF page that I've converted into a stream:
CGPDFContentStreamRef contentStream = CGPDFContentStreamCreateWithPage(pdfPage);
How can I view that stream as an NSString? I'd like to see the code that represents the PDF.
Thanks!

It's not as easy as that. A stream can be any binary data, there might be multiple chained compression formats used. See http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/PDF32000_2008.pdf (Page 23ff) for potential formats.
