Opening email attachment in iPad

Hey, am writing an application to try out ideas and want to be able to open/save email attachments similar to what happens with good reader, does anyone know of a good tutorial that开发者_Python百科 explains how to do this?

Thanks, William

I learned this from http://blog.objectgraph.com/index.php/2010/06/14/ipad-sdk-3-2-document-support-1/

and if you want to add your own filetypes read How do I associate file types with an iPhone application?

I recently implemented something like this with the help of a book called Beginning iPad Development for iPhone Developers Chapter 10 covers this topic in great detail ... better than anything I could find online.

One of the authors, Jack Nutting, was even nice enough to help me get something working after I emailed him. Good stuff.
