Question

I’m working on an iPhone app that offers the user the opportunity to send an e-mail in 3 different places in the app, and for 3 different purposes.

Rather than put the same code for showing the e-mail composer in 3 different view controllers, shouldn’t I develop a separate E-mail class, create an instance, and then set properties such as To, CC, BCC, Body, HTML_Or_Not, and so on?

Also, if I create an instance of such a class, and it brings up the e-mail composer, is it OK to release the class even before the e-mail composer has left the screen?

My advice, It’s so easy to use the built in mail picker class, just stick with it, you can create a function to setup and show the picker, and use that when you need to like so:

- (void)showMailPicker {
 if ([MFMailComposeViewController canSendMail]) {
  MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;
   picker.navigationBar.barStyle = UIBarStyleBlack;

  [picker setToRecipients: ...];

  [picker setSubject:@"Title"];

  // Fill out the email body text
  NSString *emailBody = @"email Body...";
  [picker setMessageBody:emailBody isHTML:NO];

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

Yes, it’s safe to release the picker once you have presented it, and remember that once you present the picker, you can’t change the email addresses, subject, body etc…
