I am looking for a good alternative PDF Renderer.

Currently I am using Quartz Core for PDF rendering, which is great and pretty fast, but I find it still slow compared to other iOS Apps (GoodReader has an own renderer or has adapted some kind of alternative renderer and is not disclosing any information about it).

I am wondering if there are some good open source or payd PDF Renderers for iOS that I could try out.

I tried muPDF, but it does not support iOS and it would take a lot of time to make it compatible.

Thank you!

I don't believe GoodReader has a custom render engine. It's all a matter of caching and using the idle times.

You can try this viewer: http://www.vfr.org/2011/06/pdf-reader-viewer-v1-2-1/

MuPDF compiles and runs just fine on iOS.

All you need to do is create an Xcode project for it, drop in the MuPDF, thirdparty and generated data file sources and compile. I used to have an iOS demo app for testing on the platform, but I haven't been paying the Apple developer tax so it's not up to date.

The best open source project I've found yet for iOS (iPhone/iPad) is http://www.vfr.org/ ( source code available here : https://github.com/vfr/Reader ). It has a very nice design and some nice features !
