objective c - How to Display pdfbooks in iphone except webview

Question

Iam getting pdf date from webservice.That webservice pdf link is normally displayed in webview But its performance is not good.So, for this alternative,i want to use like this

CFURLRef pdfURL= CFBundle
        //CFURLRef pdfURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("paper.pdf"), NULL, NULL);
        pdf = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);
        CFRelease(pdfURL);

But for this above coding,pdf file is locally stored named "papaer.pdf". In this place i want to display my webservice pdflink.How to do this.Please guide me. Thanks in Advance

Answer 1

Apple has a very good example for a zooming PDF the trick they are using in the above example is rendering the PDF inside a scroll view

http://developer.apple.com/library/ios/#samplecode/ZoomingPDFViewer/Listings/Classes_TiledPDFView_m.html

assuming you want to load a PDF from a url opposing to a PDF file inside your application you can replace with the following line

// Open the PDF document
        pdf = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);

        // 

if you don't want that much of an overkill you can look at Tom Brow's leaves example, its very slick even if not zoomable.

as a side-note, apple has not posted PDFkit for iPhone and iPad, even if they do have it publicly for osX - I hope they will do so one day.
