This kind of error occurs, when the given "selector action" is not named properly.

For example:

UIBarButtonItem *emailButton = [[UIBarButtonItem alloc] initWithTitle:@"Email" style:UIBarButtonItemStylePlain target:self action:@selector(xyz:)];

action:@selector(xyz:) So, here action name must be same to the button action method.
