Orientation changes when pop back to the initial viewcontroller using UINavigationController iOS 6

I have a presented a navigation controller, in which the root view controller i,e. VC1 is supported for both landscape & portrait orientations. When i push another view controller in landscape the i,e. VC2 which supports only portrait mode, come back to the VC1, the view will be turned to portrait. But i am still in the landscape mode. Please help me to solve this on iOS 6 issue.

Please check the below code.

MyViewController1 *theController =[[MyViewController1 alloc] init];
UINavigationController *navCntlr = [[UINavigationController alloc]      initWithRootViewController:theController];
[self.navigationController presentViewController:navCntlr animated:YES completion:nil];           [theController release];
[navCntlr release];

in MyViewController1

-(BOOL)shouldAutorotate
{
    return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
    return  UIInterfaceOrientationMaskAllButUpsideDown;
}

in VC2/MyViewController2 i have added the below code.

-(BOOL)shouldAutorotate
{
    return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
    return  UIInterfaceOrientationMaskPortrait;
}

i have subclassed the root navigation bar as well.

Actually this was identified as a bug in IOS6 happens with ImageViewController which only supports Portrait orientation ... so i spent lot of time and found a way around the same....

hope this helps so first things first...

add a property in your AppDelegate.h

@property BOOL model;

then in AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    self.model=NO;

    return YES;
}

also add this method in AppDelegate.m

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{

    if(!self.model)
        return  UIInterfaceOrientationMaskLandscape; //or needed orientation
    else

        return UIInterfaceOrientationMaskAllButUpsideDown;


}

then in your view controller before presenting the VC2

implement this code...

AppDelegate *appdelegate=(AppDelegate*)[[UIApplication sharedApplication] delegate];
            appdelegate.model=YES;

and then you just change the value in the viewWillDisappear of VC2

AppDelegate *appdelegate=(AppDelegate*)[[UIApplication sharedApplication] delegate];
            appdelegate.model=NO;
