Question

My app is structured like this:

- Window
 - Navigation controller
   - Table view
    - Button (in one of the rows)
 - Tab bar controller
  - tab..
  - tab..
  - tab..

(The tab bar controller isn’t added as a sub view so it can’t be seen)

How would you make the button able to manipulate the Navigation controller and tab bar controller objects?

Answer 1

Well you could have them as properties in your AppDelegate like this:

@property (nonatomic, retain) UINavigationController *navigationController;
@property (nonatomic, retain) UITabBarController *tabBarController;

And than in your table view you can get a pointer to them like this:

UINavigationController *navigationController = [(YourAppDelegateClass *)[[UIApplication sharedApplication] delegate] navigationController];
UITabBarController *tabBarController = [(YourAppDelegateClass *)[[UIApplication sharedApplication] delegate] tabBarController];

After this you can have your button do whatever you want to them. Let me know if this works for you.
