How to pass data back to the original UINavigationController

StoryBoard

I would like to pass some data from the last Table View to the First View. How can I do grab a hold of the First View object? I'm familiar with delegate pattern. From the First View, I'm using Style Modal to invoke the Table View.

to get your rootViewController of your navigation controller, you can try this

NSArray *viewControllers = self.navigationController.viewControllers;
YourRootViewController *rootViewController = (YourRootViewController *)[viewControllers objectAtIndex:viewControllers.count - 2];

and add your data to rootViewController

Create an object to manage your data model outside of your controller structure (singleton or owned by the application delegate). Update it when you have new data and read from it when you want to display something. Then, instead of having to make links between controllers, all you need to do is remove the one or ones you don't want and let the one you go back to decide what to show.
