How to structure an app when using UINavigationController as the window's root view

I'm starting to learn iOS development and am attempting to use UINavigationController as my window's root view. All is working well but I need some advice on how to structure my app. I read the docs and some questions on here too.

Since the navigation controller is managing all my other content view controllers, then all of these view controllers need a way to send messages to the navigation controller. Right? So, I've thought about making a singleton navigation controller that any other view controller can call on to push new view controllers on it. Or, if each view controller has a reference to the navigation controller then they can push/pop easily as well. This is the part I'm not sure about.

Also, for having buttons and actions I have been setting the target as the navigation controller and from there it can handle it correctly and push or pop on it's own. I did subclass UINavigationController for this. And I have my view controllers as references in it. However I ran into an issue where my UITableViewController was handling a selection of a row and I need to push a new view controller on top, but how do I get the reference to the navigation controller?

I hope that makes sense, and any advice on how to structure this would be very appreciated.

Thanks!

I think you're overthinking this. View controllers have a navigationController property built in allowing you to reference the navigation controller. That being said, pushing to a new view controller from within a view controller that is embedded in a navigation controller is as easy as:

UIViewController *myNewViewController = [[UIViewController alloc] init];

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

According to your requirement you need to write like this :-

     UIViewController *myNewViewController = 
    [[[UIViewController alloc] 
    initWithNibName:@"yourNibName"] 
   bundle:nil]];

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

This will push one controller on the bottom of the stack.
