create custom pdf viewer for iphone

I want to develop a custom pdf viewer, in which I can add features like:

• bookmarks
• jump to specific page
• take some notes
• page flipping effect

Can you suggest some libraries in Cocoa touch to fullfill my requirem开发者_如何学JAVAents?

I followed the PDF viewing tutorial in which a webview was used but it only provides basic scrolling and zoom facilities. I have seen some apps in which bookmarks and page flipping is possible. Kindly suggest me something so that I can integrate more features.

I think this older answer here on stack overflow will give you some answers.
