Question

I ran into strange issue

case 5:
        if(1==2) {NSLog(@"Here is a tmp stuff");}
        AuthenticationViewController *authVC = [[AuthenticationViewController alloc] initWithNibName:@"AuthenticationViewController" bundle:[NSBundle mainBundle]];
        [authVC setTitle:@"Authentication"];
            //self.authViewController = authVC;
            //[authVC release];

        [self.navigationController pushViewController:authVC animated:YES];

        break;

If i remove the useless if statement it fails to compile. I m unable to understand why?

You are declaring a variable in your case statement, which is illegal in C.
