    Convert it into an image and mail that image as an attachment.

    + (UIImage *) imageWithView:(UIView *)view
{
    UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, [[UIScreen mainScreen] scale]);
    [view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage * img = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return img;
}

-(void)displayComposerSheet 
{
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;
    [picker setSubject:@"Check out this image!"];

    // 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
    UIImage *coolImage = ...;
    NSData *myData = UIImagePNGRepresentation(coolImage);
    [picker addAttachmentData:myData mimeType:@"image/png" fileName:@"coolImage.png"];

    // Fill out the email body text
    NSString *emailBody = @"My cool image is attached";
    [picker setMessageBody:emailBody isHTML:NO];
    [self presentModalViewController:picker animated:YES];

    [picker release];
}
