How to access Navigation Bar from a View Controller of a subview ?

I have a View Controller where I select some data into an array and then optionally on clicking of a button I show that data in a TableView added as a subview to previous view with a flip animation.

Now I have the facility to delete data from array I have picked from first view and passed to this one.

Now I have a condition that there is a button on the righthand side on the navigationBar on whose controller the previous view was pushed.

Now that button needs to be disabled until there r atleast X number of elements in the array. so while I am adding data In my previous view, I keep check on the array and as soon it crosses the required count , I enable the button.

Now in the other view which is a TableView which has been brought in with animation, Whenever I delete data I need to disable the button again when it goes below the number X.

How can I access the navigationBar's button in this subview's controller ? shall I set the first view Controller as delegate in the next one ?

My opinion is you can create a uinavigationController object in your subview and assign it from your parent view(Where you have the navigation controller object). You can then access the navigation controller in the subview.

try using superView proprty or loop through all the pushed ViewController and check if it is previous VC. Then make the button enabled or disabled

If your viewController is inside UINavigationViewController, you can set navigationBar buttons with self.navigationItem.leftBarButtonItem and self.navigationItem.rightBarButtonItem.
