I have a large local PDF. How can I use three20 Project for showing the PDF page by page with zooming, swiping functionalities?

Is there any other free library available to achieve this functionality?

I tried to use the Apple WWDC 2010 code but facing some problems (I am showing PDF Pages instead of images). The question related to it is here, In photoscroller app (iPhone WWDC-104 Photos App) uiscrollview images shift to right when called using presentModalviewController

Kindly help me.

  • I think your previous approach was a better one. The most likely answer to your UIScrollView problem would seem to be that one of the sizes / offsets has ended up incorrect somehow. Try posting more of your code in the original question, or providing a copy of the whole project people can download to see. – JosephH Oct 07 '10 at 08:06

Why do you think that Three20 can achieve this? Three20 is not a magical library that can solve all of the problems in iPhone OS. Try using the normal approach, one of them is available in this blog post.
