In my app for iPad I have several videos and pdfs. What I want is when user is watching a video or reading a pdf and if he wants to email that video or pdf to himself or to his friends, then how would he do it? I have added a button on the navigation bar for this purpose. When the user clicks that button an option should appear which should say "Email". now when the user selects Email, the app asks the user to enter an email address. After entering email address the user presses "Send" button. And that particular file is sent to the user's email. How can this be done?

Thanks
