Mail composer gives an error in Xcode - objective-c

Question

I'm trying to senda a mail with a iOS app.
This is the method:
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:#"Reclutamento pompieri"];
// Set up the recipients.
NSArray *toRecipients = [NSArray arrayWithObjects:#"test#gmail.com",nil];
[picker setToRecipients:toRecipients];
testoMail = [NSMutableString stringWithFormat: #"This is a test"];
[picker setMessageBody:testoMail isHTML:YES]; //HTML!!!!!!
[self presentViewController:picker animated:YES completion:nil];
//*******************************************************************************************
// The mail compose view controller delegate method
- (void)mailComposeController:(MFMailComposeViewController *)controller //**ERROR STAYS HERE**
didFinishWithResult:(MFMailComposeResult)result
error:(NSError *)error
{
[self dismissModalViewControllerAnimated:YES]
;
But the debugger says "Used undeclared identifier "mailComposerController"
I dont't understand what it means.
Can you help me?
Tank you very much

Answer 1

It seems that you have defined - (void)mailComposeController:(MFMailComposeViewController *)controller inside a method.
Please define this outside the method.
Edit
As I said move definition out side the method.
Here is you full correct .m file

Answer 3

Add the MessageUI.framework to your project. Click on your project in the Navigator, select 'Build Phases' and then add it under the 'Link with library' section.
