Set First Responder in MFMailComposeViewController?

Question

I\'m using Apple\'s MailComposer example application to send email from within my application (OS 3.0 functionality). Is it possible to set the To, Subject, or Body fields a

Answer 1

You are able to make these fields become the first responder.

if you add the following method to your class...

//Returns true if the ToAddress field was found any of the sub views and made first responder
//passing in @"MFComposeSubjectView"     as the value for field makes the subject become first responder 
//passing in @"MFComposeTextContentView" as the value for field makes the body become first responder 
//passing in @"RecipientTextField"       as the value for field makes the to address field become first responder 
- (BOOL) setMFMailFieldAsFirstResponder:(UIView*)view mfMailField:(NSString*)field{
    for (UIView *subview in view.subviews) {

        NSString *className = [NSString stringWithFormat:@"%@", [subview class]];
        if ([className isEqualToString:field])
        {
            //Found the sub view we need to set as first responder
            [subview becomeFirstResponder];
            return YES;
        }

        if ([subview.subviews count] > 0) {
            if ([self setMFMailFieldAsFirstResponder:subview mfMailField:field]){
                //Field was found and made first responder in a subview
                return YES;
            }
        }
    }

    //field not found in this view.
    return NO;
}

Then, after you present the MFMailComposeViewController, pass the MFMailComposeViewController's view into the function along with the field you want to become first responder.

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

/*Set up the mail composer*/

[self presentModalViewController:mailComposer animated:YES];
[self setMFMailFieldAsFirstResponder:mailComposer.view mfMailField:@"RecipientTextField"];
[mailComposer release];
