Objective C: Send email without leaving app

Question

How do I send an email within an app without leaving the app.

This works:

-(void) sendEmailTo:(NSString *)to withSubject:(NSString *)subject withBody:(NSString *)body {
NSString *mailString = [NSString stringWithFormat:@"mailto:?to=%@&subject=%@&body=%@",
                        [to stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding],
                        [subject stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding],
                        [body stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailString]];
}

but goes to the mail app to send. Is there a way to do this without leaving the app?

Yes. Use the MFMailComposeViewController.

// From within your active view controller
if([MFMailComposeViewController canSendMail]) {
    MFMailComposeViewController *mailCont = [[MFMailComposeViewController alloc] init];
    mailCont.mailComposeDelegate = self;

    [mailCont setSubject:@"yo!"];
    [mailCont setToRecipients:[NSArray arrayWithObject:@"joel@stackoverflow.com"]];
    [mailCont setMessageBody:@"Don't ever want to give you up" isHTML:NO];
    [self presentViewController:mailCont animated:YES completion:nil];

}


// Then implement the delegate method
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
    [self dismissViewControllerAnimated:YES completion:nil];
}
