Hello all.
Another question still regarding with pdf's.
when I load a pdf into a web view, I can tap for a while and the magnification
loop will appear, this doesn't happens when using Quartz..
I was reading some post on internet, and the authors create their own
magnification view. Is there
Oh sorry, I should have read before posting the question again, I see somebody
its talking abour PDFSelection, and I say an example in the developer site.
So for the selection I will check that.
Now I have only the question about the loupe :S
thanks for any help

You can use the CGPDF API. However be careful on memory usage (in particular
keeping the CGPDFDocument open all the time could lead to some memory issues
that could be workarounded by closing and reopening it)

UIWebView is the easiest way to view PDFs. But if you want any editing or other
custom manipulation, will need to drop down lower to CoreGraphics.

Laurent hi.
About your warning.

then get the required page using CGPDFDocumetnGetPage(), dra the page then
release the CGPDDocument?.. and when swapping pages just release the current
page, open document again get next
Hi Gustavo,
When you draw a CGPDFPageRef into a graphic context, Quartz will hold images
inside the PDF page in a sort of cache (at least, it seems with Instrument
Object Alloc). You can only empty that cache by destroying the
CGPDFDocumentRef.
However, if you do not destroy your

Thanks for the info,, I will be testing the behavior with some pdfs and see
whats better, to keep the CGPDFDocumentRef and destroy it when closing the
pdf.. or open-close each time I change.. I guess I must decided what I want
speed vs memory usage.
