iPhone: How to Close MFMailComposeViewController? - iphone

Question

I'm having difficulties closing an email message that I have raised.
The email opens nicely, but once it is opened it will not close as the mailComposeController:mailer didFinishWithResult:result error:error handler never gets invoked.
As far as I can tell I have all the bits in place to be able to do this.
Anyone any ideas of what I can look at?
Here is how I raise the email:
-(IBAction)emailButtonPressed
{
NSString *text = #"My Email Text";
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.delegate = self;
[mailer setSubject:#"Note"];
[mailer setMessageBody:text isHTML:NO];
[self presentModalViewController:mailer animated:YES];
[mailer release];
}
and later in the class I have this code to handle the close (but it never gets called):
-(void)mailComposeController:(MFMailComposeViewController *)mailer didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
[self becomeFirstResponder];
[mailer dismissModalViewControllerAnimated:YES];
}
My header file is defined as:
#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
#interface myViewController : UIViewController <UIActionSheetDelegate, UIAlertViewDelegate, MFMailComposeViewControllerDelegate, UINavigationControllerDelegate>
Thanks

You are setting the delegate wrong, the delegate property in MFMailComposeViewController is called mailComposeDelegate, so it should be:
mailer.mailComposeDelegate = self;
Another possible error I can see is calling dismissModalViewControllerAnimated: on mailer - you should send this message to the view controller who presented the mail interface - self in this case:
[self dismissModalViewControllerAnimated:YES];
I wrote "possible error" because it might actually work if iOS routes the message through responder chain, anyway - the documentation says it should be send to presenter.
