how to get rootviewcontroller ios storyboard

I have a menu table in the root view of a storyboard that I want reloaded whenever a sub view updates data. How do I get a reference to the root view so that I can call the reloaddata method on it?

From the console:

po [[[UIApplication sharedApplication] keyWindow] rootViewController] <UINavigationController: 0x15f076c00>

You can access it using the below code if the rootViewController is a UIViewController

UIViewController *rootController=(UIViewController *)((AppDelegate *)[[UIApplication sharedApplication] delegate]).window.rootViewController;

But if it's a UINavigationController you can use the code below.

UINavigationController *nav=(UINavigationController *)((AppDelegate *)[[UIApplication sharedApplication] delegate]).window.rootViewController;
UIViewController *rootController=(UIViewController *)[nav.viewControllers objectAtIndex:0];
