Opening Messages App to compose an sms to recipient:

Opening Mail app to compose an email to recipient:

NSString *stringURL = @"mailto:[email protected]";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

You can also include a subject field, a message, and multiple recipients in the To, Cc, and Bcc fields. (In iOS, the from attribute is ignored.) The following example shows a mailto URL that includes several different attributes:
mailto:[email protected][email protected]&subject=Greetings%20from%20Cupertino!&body=Wish%20you%20were%20here!
Note: Compose email dialog can also be presented within app using MFMailComposeViewController.
