Question

I have warning on with error message below. Please help.

Assigning to 'id<MFMailComposeViewControllerDeelegate>' from incompatible type 'MyViewController'
and
Class 'MyViewController' does not implement the 'MFMailComposeViewControllerDelegate' protocol

The code is

-(void)displayComposerSheet 

{

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];

//below bold code is warning 

    **picker.mailComposeDelegate = self;**

[picker setSubject:@"My first apps!"];


// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObjects: nil]; 


[picker setToRecipients:toRecipients];

[picker setMessageBody:TextView.text isHTML:NO];

[self presentModalViewController:picker animated:YES];

[picker release];

}

Answer 1

The problem is as the error says: your class MyViewController doesn’t conform to the MFMailComposeViewControllerDelegate protocol. Your interface line should look something like this:

@interface MyViewController : UIViewController <MFMailComposeViewControllerDelegate>

And, of course, you should be sure to implement mailComposeController:didFinishWithResult:error: in your class.
