Q:

Looking for an open source PDF Framework for iPad

My customer wants a pdf reader which has a page curl effect.  Also, he wants it to be zoomable as well.  I tried using the UIPageViewController but it doesn't support zooming (as far as I know).  I also tried using both UIScrollViewController and UIPageViewController by switching between these 2, but it's not so smooth.  
Does anyone know any free framework that meets my requirements? 
I don't want any content searching, highlighting or anything, just the reader and thumbnail view.

Have a look at this:

Hope this helps...
