You can access the parent view controllers from any other pushed view controller. The very first element in the collection of parents is the root view controller. Access this element, cast it to your specific implementation, then access your array object from it. So something like:

UIViewController * rootVC = [self.navigationController.viewControllers objectAtIndex: 0];
NSArray * myArray = ((MyUIViewController *) rootVC).myArrayProperty;
