Question

I am getting this error message,Whenever I show alertview in function :

- (void)navigationController:(UINavigationController *)navigationController 
                       willShowViewController:(UIViewController *)viewController
                       animated:(BOOL)animated {

and then handling the click action in :

-(void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex

I saw all related posts but however didn't get any solution to this coz i dont have any keyboards on. I am only using navigation functions and alertview inside it. App is also crash due to this problem. any help will highly appreciated.
