Accessing a view controller created through Storyboard using the App Delegate
delegates, ios5, iphone, objective-c, storyboard
Solution
You'll have to traverse the view hierarchy from the app delegate. Assuming the `AppDelegate` holds a reference to the `UITabBarController`, you could use the `viewControllers` property or `selectedViewController` property to get to your view controller.
Problem
I'm working on an iOS5 app using storyboard, and I have a method in a view controller class that i'd like to access from the App Delegate. The trouble is, this view controller gets instantiated via a tab bar controller in storyboard, so the App Delegate has no direct way of calling the method I want... For a view controller to get in touch with the App Delegate, all one has to do is use: ``` MyAppDelegate *appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate]; ``` Is there a similarly easy way of pointing to an already-instantiated view controller or class?
