@ Selector does not work out anomalies

I have this piece of code in the controller
- (Void) viewDidLoad
{

UIBarButtonItem * addButton = [[UIBarButtonItem alloc] initWithTitle: @ "add" style: UIBarButtonItemStyleBordered target: self action: @ selector (addANote :)];
self.navigationItem.rightBarButtonItem = addButton;
[AddButton release];
[Super viewDidLoad];
/ / Do any additional setup after loading the view from its nib.
}

However, when running, a click on the Add button will be abnormal, the breakpoint break in movl 8 (% edx),% edi, in the code there is a method to this addANote, scholarship ios did not take long, really do not know how, help us to see, thank you
