if you want to access superview use the statement said by Jhaliya, If you want to access superviewcontroller property frm subviewcontrller property , use

id mainViewController = [self.view.superview nextResponder];

here mainViewController is the superviewcontroller reference.

There a parentViewController property in UIViewController class reference, This property is used for navigation, tab bar, and modal view controller hierarchies.

The above syntax is used for when you are setting a view as subview to a parentviewcontroller

---

You can access the super view controller using the parentViewController property on every UIViewController.

UIViewController *parent = self.parentViewController;

---

You can use superView method of UIView to access its parrent.

UIView *mySuperView = [MySubView superView];

---

use superview property of UIView.

UIMyView* mySuperView =  (UIMyView*) myView.superview ;
mySuperView.mytextString = @"Assign string to super view";

EDITED:

You could get the list of all your UIViewController by using methods of UINaigationController . Also current visible controller and top view controller,

Read the documentation for UINavigationController .
