Go straight to a view controller by replacing the window's root view controller (with storyboard)

storyboardReplace.m

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
    UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"aaa"];
    
    [UIView transitionFromView:src.view
                        toView:dst.view
                      duration:0.28
                       options:UIViewAnimationOptionTransitionFlipFromLeft
                    completion:^(BOOL finished) {
                        [[UIApplication sharedApplication].delegate window].rootViewController = dst;
                    }];
