A standard view controller, whose interface lets the user manage, edit, and send email messages.

Use this view controller to display a standard email interface inside your app. Before presenting the interface, populate the fields with initial values for the subject, email recipients, body text, and attachments of the email. After presenting the interface, the person can edit your initial values before sending the email.

The composition interface doesn’t guarantee the delivery of your email message; it only lets you construct the initial message and present it for user approval. The person may opt to cancel the composition interface which discards the message and its contents. If the person opts to send the message, the message queues in the user’s Mail app outbox. The Mail app is ultimately responsible for sending the message.

An alternate way to compose emails is to create and open a URL that uses the mailto scheme. URLs of that type go directly to the built-in Mail app, which uses your URL to configure a message. For information about the structure of mailto URLs, see Apple URL Scheme Reference.
