How to attach a file from ipad in your application?

I have developed an application in ipad, i want to browse a file from ipad and attach it to my apps..it should not be like e-mail attachment..am sorting out the code but am ge开发者_JS百科ttin code for only email attachment

The only files on the iPad your app will be allowed to browse are the files inside your app's sandbox or those accessed using a framework like the Assets Library Framework. As for "attaching a file to your apps", what do you mean by that? Can you clarify?
