Answer 1

It’s trying to protect you from setting the .delegate property to an object that might not implement the delegate methods.

In your .h file, you need to make it declare that it implements the delegate protocol.

@interface myVC : UIViewController <MFMailComposeViewControllerDelegate>
{
...
}
