Returning to app after sending to mail client

The jamie oliver application and the nigella quick collection开发者_如何学编程 apps both return the user to the application after they've sent a feedback email.

My question is, how do I return a user to the app after sending them to the email client. Plus, is there any way to do this with the safari app too? After sending them to a URL?

Thanks

Tom

I haven't used the Jamie Oliver app but I believe he is using the MFMailComposeViewController. If you want more info on how to send an email from within an app, take a look at this question.
