I have a problem I want to control the backBarButtonItem when I click on it Action backAction "works my problem is that SetAction does not work, I hope there is a solution for the controller backBarButtonItem

- (void)viewDidLoad {

    [self.navigationItem.backBarButtonItem setTarget:self];
    [self.navigationItem.backBarButtonItem setAction:@selector(backAction)];


    [super viewDidLoad];
}

- (void)backAction {
    if ((isSaveCarte==NO)&&(isNewCarte)) {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"Voulez vous Enregistrer la Carte" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Save",nil]; 

        [alertView show]; 
        [alertView release];

back bar button item is meant for navigating back...

why don't you use the leftBarButtonItem instead of backBarButtonItem.. the only difference would be it wont be a left pointed button.. but you are not navigating back anyways right?
