Updating navigation bar

Rated 3.84/5 based on 733 customer reviews

Hello to everybody I'm having the following problem, I have two views A & B in order to go from A to B i'm just pushing the new view, in view B I preform some actions that update the badge Value of a UIBar Button item of my navigation bar.

(Like adding an item to the shopping cart) When I go back to view A using the navigation Bar Back button the UIBar Button item shows the previous badge Value, instead of the updated one, I guess this happens because when you press the back button view B is popped revealing view A which is left as it was without any changes so, I need a way to tell view A to update itself after returning.
