Inter application communication in iphone

I just wanted to know if there is any way to access a document from outside the application in iphone. For instance, I want to be able to send a word document from mail to my application. How can I achieve this?

T开发者_开发技巧hanks in advance!

Here is a blog that describes how inter-app communication works in iOS Apps.

iPhone Apps are sandboxed. iPhone SDK does not allow you to go out of your sandbox

In simple terms when you build a application there will be a folder created for you and Apple doesnt provide you to access anything that is outside of that folder. All your resources are confined inside that folder.

But you can access some of specific items such as Address Book, Photo Library. But definitely not mails.
