Note in iOS 6 shouldAutorotateToInterfaceOrientation is deprecated. Instead you should use supportedInterfaceOrientations and return a UIInterfaceOrientationMask.

So for example:

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

Here are all the UIInterfaceOrientationMask options you might return:

UIInterfaceOrientationMaskAll
UIInterfaceOrientationMaskAllButUpsideDown
UIInterfaceOrientationMaskLandscape
UIInterfaceOrientationMaskLandscapeLeft
UIInterfaceOrientationMaskLandscapeRight
UIInterfaceOrientationMaskPortrait
UIInterfaceOrientationMaskPortraitUpsideDown

You should also consider the preferredInterfaceOrientationForPresentation.

In general, orientation should only change from portrait to landscape (or vice versa) when the user rotates the device.

However, if you want your RootViewController to always present its view in portrait and your OtherViewController to always present itvs view in landscape, that's easy enough.

In your RootViewController's .h:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

In your OtherViewController's .h:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

Although this would probably be better as it would allow both landscape-left and landscape-right rotations:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

I m sorry but it's not giving the otherViewController in Landscape on Buton click. — user440485, Sep 14 '10 at 06:18
(1) don't use `br` tags (2) you didn't need to post three separate comments (3) Set a breakpoint in these functions. Does the breakpoint get hit? — Shaggy Frog, Sep 14 '10 at 06:35

The only way I am aware this can be done is by presenting otherViewController modally.

See my answer here: UIViewController loads rotated to landscape but only supports portrait

Maybe it helps.

in viewWillAppear of your new view controller add

[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscape]

and in viewWillAppear of your root viewController add

[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait];

It will cause warning but it works.

Also, this is undocumented API and cause for app rejection. – Johan Kool Sep 14 '10 at 07:37
