iOS - support Rotations for specific ViewControllers

Question

I have a hierarchy of 3 views

I've created a subclass for my NavigationViewController, and setup a property Landscape which determines whether each viewController can support different orientations.

This property is set in the ViewWillAppear of each View controller: this works perfectly. Controller 1 and 2 are portrait only, and controller 3 supports both portrait and landscape orientations.

The issue arrises when I'm going back popping controller 3 to go back to controller 2 IF i'm in controller 3 in landscape orientation, and I click the back button, my Controller 2 is presented to me in Landscape orientation : (controller 2 does not support Landscape)

Then i have to rotate the device for the orientation to fix itself . . . .

code in Navigation Controller - (BOOL)shouldAutorotate { return YES; }

- (NSUInteger)supportedInterfaceOrientations
{
   if (LandscapeOK) {
       // for iPhone, you could also return UIInterfaceOrientationMaskAllButUpsideDown
       return UIInterfaceOrientationMaskAll;
   } else {
    return UIInterfaceOrientationMaskPortrait;
}

Code at Each ViewControllers ViewWillAppear Method

[(NavigationViewController *)[self navigationController] setLandscape:YES];

I have my code set up almost exactly the same way as this question: the same problem as well. Question was posted a year or so back but yet no appropriate solution - while going through the answers listed

iOS 6: How do I restrict some views to portrait and allow others to rotate?

From 'Hierarchy', do you mean, you have one parent 'NavigationViewController' with property 'Landscape' on it, while all the other controllers (1, 2, & 3) derive from it? — Macrosoft-Dev, Sep 20 '13 at 17:33
yes - there is a button in each VC that leads to the next 1 -> 2 -> 3 — Taskinul Haque, Sep 20 '13 at 17:47

Given 1. the reply you have given to my comment, 2. you have tried the solution suggested below:

iOS 6: How do I restrict some views to portrait and allow others to rotate?

what I perceive, you have same/common property LandscapeOK accessible across all controllers.

I suggest you to debug and check value of LandscapeOK inside supportedInterfaceOrientations, when you naviagte back to controller 2 from Controller 3.
