Creating HTML email from UITextField text

Question

I'm a novice and recreational programmer. I am trying to create an app for iOS that populates the text from my UITextFields. I have 3 the actionField, impactField, and result Field. I'd like for each to have their own line, if possible.

I looked at a similar answer, but it was not any help for me. Does anyone have any tutorials or advice?

- (IBAction)backgroundTap: (id)sender {
    [self.actionField resignFirstResponder];
    [self.impactField resignFirstResponder];
    [self.resultField resignFirstResponder];
}

- (IBAction)sendBullet:(id)sender {
    NSString *emailTitle = @"Email";
    NSString *messageBody = @"Title";
    NSArray *toRecipients = [NSArray arrayWithObject:@"email"];

    MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
    mc.mailComposeDelegate = self;
    [mc setSubject:emailTitle];
    [mc setMessageBody:messageBody isHTML:NO];
    [mc setToRecipients:toRecipients];

    [self presentViewController:mc animated:YES completion:NULL];

Answer 1

All you need to do is build a string from the text fields:

NSString *messageBody = [NSString stringWithFormat:@"Action: %@\nImpact: %@\nResult: %@", self.actionField.text, self.impactField.text, self.resultField.text];

Update the format string as needed. What I present here is just one example.

The \n is a special value in a string that means "newline". This means the string I show will consist of three lines of text.
