Question

Am using iOS6 device xcode 4.5 & mountain lion mac.
And in my app am starting in portrait mode(3 screens).
But 4th screen should be in landscape and should support landscape left & landscape right.

Most of the explanations are shown how to rotate.

in appddelegate am using

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
      UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
navigationController.navigationBar.tintColor = [UIColor blackColor];


// Set RootViewController to window
if ( [[UIDevice currentDevice].systemVersion floatValue] < 6.0)
{
    // warning: addSubView doesn't work on iOS6
     [self.window addSubview: navigationController.view];
}   
else
{
     // use this mehod on ios6
     [self.window setRootViewController:navigationController];
}

}
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if(self.shouldRotate ) //shouldRotate is my flag
    {
         self.shouldRotate = NO;
         return (UIInterfaceOrientationMaskLandscapeRight);
    }
    return (UIInterfaceOrientationMaskPortrait);
}

and in my view controller which should be landscape and am using

 - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
     AppDelegate *appDelegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self)
    {
         appDelegate.shouldRotate = YES;
        // Custom initialization
    }
     return self;
 }



- (BOOL)shouldAutorotate
{
     return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
      return UIInterfaceOrientationMaskLandscape;
}

In my viewcontrollers which are potrait are working correctly in which am using

- (BOOL)shouldAutorotate
{
     return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
      return UIInterfaceOrientationMaskPortrait;
}

can any one suggest to do this

Thanks in advance

This is working for me
I removed NavigationController and changed as follows

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
    {
        self.viewController = [[PlashViewController alloc] initWithNibName:@"PlashViewController" bundle:nil];
    }
    self.window.rootViewController = self.viewController;
   [self.window makeKeyAndVisible];
   return YES;
}

im my app am placed this methods in my view controllers as follows
and in plist and target i specified three orientations like portrait , landscapeleft and landscaperight
to show view in portrait

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

to show view in landscape

 - (BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
   return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}
