Answer 1

In your .h file, conform your class to those delegate protocols by adding <, your protocols that you want to conform to (comma-separated), and then a closing >.

Example:

@interface MyClass<MFMessageComposeViewControllerDelegate, UINavigationControllerDelegate>

,,,

@end

You need to then implement the required methods in the protocols in your .m file.

Take a look at the required methods of these protocols in their respective documentation:

MFMessageComposeViewControllerDelegate

UINavigationControllerDelegate
