PDF Viewer iPad App [closed]

Answer 1

You could port Xpdf or the forked Poppler to iOS and use their rendering capabilities as well as retrieving information such as bookmarks and URI links from the PDF for use in your application.

Answer 2

There is a payed option named http://pspdfkit.com/

I have been looking at the example and it seams to work the way I was hoping to find some code example

Answer 3

For a simple and effective PDF viewer, you can now (iOS 4.0+) use the QuickLook framework:

QLPreviewController *previewController = [[QLPreviewController alloc] init];
previewController.dataSource = self;
previewController.delegate = self;
previewController.currentPreviewItemIndex = indexPath.row;
[self presentModalViewController:previewController animated:YES];
[previewController release];

You need to link against QuickLook.framework and #include <QuickLook/QuickLook.h>

For anything more complex, just grab the excellent PSPDFKit.

Answer 4

Here is a nice example of a pdf reader on github. It does not do the advanced things (like text search), but it might be good as a starting place. Seems to do OK with large pdfs, so maybe the performance is not too bad.

Answer 5

I've developed a custom reader like this which I've used for a handful of projects for clients. Search & Highlight was by far the most difficult, followed by text selection. Keeping memory usage low for large PDF's is tricky too.

I cant share my source. But here's someone who has a free library that looks promising:

(it doesn't look as if the source code is available?)

Update: I can't find any PDF component/library for iOS, which doesn't surprise me. So here's a crazy alternative (so crazy it just might work): Write your app in C#/.Net using MonoTouch, and incorporate the free .Net library iTextSharp. I have no idea if this would work or not.

Another idea might be to incorporate a web service (running on a server somewhere) that will convert your PDF into HTML for you. Your server component can be written in any language, which expands your PDF-component options considerably. And the things you want to do in your bullet points would be a lot easier to implement yourself with HTML.
