Hello all,

I am caught in a strange requirement .See the following view hierarchy and scenario .

I have a tab bar application in which I have three tabs .

In first tab I am showing some content with a small image title and date (uitableview in navigation controller).

In the detail view of that controller there are more buttons that shows different sorts of detail like gallery button and , more details button and some , more button .

On tapping each button I will push each individual view controller in the main navigation controller .

Now on the horizontal orientation I am showing same list of content but in the cover flow ( in modal view controller ) fashion like the ipod application .

On tapping any image we will show the same buttons like gallery and more details and tapping on it will show the new controller with the following code :

UINavigationController *modalNavController = [[UINavigationController alloc] initWithRootViewController:myPhotoController];

UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(backButtonPressed)];

myPhotoController.navigationItem.leftBarButtonItem = backButton;
[backButton release];

if([self.modalViewController isViewLoaded]){
    [self dismissModalViewControllerAnimated:YES];
}
modalNavController.navigationBar.barStyle = UIBarStyleBlackOpaque;  
[self presentModalViewController:modalNavController animated:YES];

[modalNavController release];

All this is working nicely . but when I get back the device in vertical orientation . the main modal controller will be dismissed and all the containing modal controller also will be dismissed if they are open or not .

Instead of this what I want is If chooses an item in the coverflow and then if chooses gallery and if I put the device in vertical orientaion the gallery should be in the navigation hierarchy that drove me to the main list and gallery should be in horizonatal fashion .

So what I want to do is that just to push the gallery controller in the main navigation hierarchy instead of showing from a madal controller .

If someone wants reference then see the application "net a porter" I want to do like that . Just tell me how the controller hierarchy is working in that app . I need the help .

Thanks
