Moving View Controller to the top of navigation stack iOS
Yahoo
How do I move a VC pushed into navigation stack to be on top?
Suppose I pushed it in this order
Push VC1
Push VC 2
Push VC 3
So now currently I have VC3 on top. How do I programmatically bring VC2 to front? So that the stack becomes
VC1,VC3,VC2

As a developer, you have an access to navigation controller stack by manage its viewControllers array:
NSArray *currentStack = self.navigationController.viewControllers
Discussion The root view controller is at index 0 in the array, the back view controller is at index n-2, and the top controller is at index n-1, where n is the number of items in the array.
Assigning a new array of view controllers to this property is equivalent to calling the setViewControllers:animated: method with the animated parameter set to false.
It is simple an array, that holds the vcs that are currently in nav's stack and you can manage this array like the others:
NSMutableArray *tempArray = [NSMutableArray arrayWithArray: currentStack];
[tempArray removeObjectAtIndex:1];
[tempArray addObject:secondVC];
self.navigationController.viewControllers = tempArray;
There are a set of available methods that you can play with:
