Does anyone know whether there is a way to get progress info from a
PDF loading into a view - percentage/bytes loaded for example?
No, I can think of no way to do this.
Be careful with threading and PDF... PDFKit classes are ultimately
based on CFPDFDocumentRef and CGPDFPageRef — these are not thread
safe. You cannot for example search for text in a PDFDocument while
rendering a PDFPage from that same PDFDocument. Or even render two
different PDFPages from the PDFDocument.
You can however have several CGPDFDocumwentRefs that point to the same
underlying file/data working on separate threads. You want separate
PDFDocument objects though:
PDFDocument *mainPDFDocument = [[PDFDocument alloc] initWithUR:
someURL];
PDFDocument *threadPDFDocument = [[PDFDocument alloc] initWithUR:
someURL];
Note, same URL, different PDFDocument instance.
