iphone app send email

Question

I know how to send an email within my app by launching the Mail app then returning to my app... but I would like to my app to be able to send email without opening the mail app. For exemple i'd have a button in my app clicking that button would send out an email. I will then notify the user that the email has been sent...

Has anyone been doing this ?

thanks.

Here is a sample code to send email using MFMailComposeViewController.

-(IBAction)showPicker:(id)sender {
// This sample can run on devices running iPhone OS 2.0 or later  
// The MFMailComposeViewController class is only available in iPhone OS 3.0 or later. 
// So, we must verify the existence of the above class and provide a workaround for devices running 
// earlier versions of the iPhone OS. 
// We display an email composition interface if MFMailComposeViewController exists and the device can send emails.
// We launch the Mail application on the device, otherwise.

Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
if (mailClass != nil)
{
    // We must always check whether the current device is configured for sending emails
    if ([mailClass canSendMail])
    {
        [self displayComposerSheet];
    }
    else
    {
        [self launchMailAppOnDevice];
    }
}
else
{
    [self launchMailAppOnDevice];
}
}

-(void)displayComposerSheet {
// Displays an email composition interface inside the application. Populates all the Mail fields. 

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;

[picker setSubject:@"Hello from California!"];


// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObject:@"first@example.com"]; 
NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil]; 
NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com"]; 

[picker setToRecipients:toRecipients];
[picker setCcRecipients:ccRecipients];  
[picker setBccRecipients:bccRecipients];

// Attach an image to the email
NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"png"];
NSData *myData = [NSData dataWithContentsOfFile:path];
[picker addAttachmentData:myData mimeType:@"image/png" fileName:@"rainy"];

// Fill out the email body text
NSString *emailBody = @"It is raining in sunny California!";
[picker setMessageBody:emailBody isHTML:NO];

[self presentModalViewController:picker animated:YES];
[picker release];
}


- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {  
// Dismisses the email composition interface when users tap Cancel or Send. Proceeds to update the message field with the result of           the operation.
message.hidden = NO;
// Notifies users about errors associated with the interface
switch (result)
{
    case MFMailComposeResultCancelled:
        message.text = @"Result: canceled";
        break;
    case MFMailComposeResultSaved:
        message.text = @"Result: saved";
        break;
    case MFMailComposeResultSent:
        message.text = @"Result: sent";
        break;
    case MFMailComposeResultFailed:
        message.text = @"Result: failed";
        break;
    default:
        message.text = @"Result: not sent";
        break;
}
[self dismissModalViewControllerAnimated:YES];
 }

-(void)launchMailAppOnDevice {

// Launches the Mail application on the device.
NSString *recipients = @"mailto:first@example.com?cc=second@example.com,third@example.com&subject=Hello from California!";
NSString *body = @"&body=It is raining in sunny California!";

NSString *email = [NSString stringWithFormat:@"%@%@", recipients, body];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];
