I only want to support different Orientations on one View in my UINavigationController Stack. How can I do this?

It also has to work in iOS5.

objective-c uiviewcontroller uinavigationcontroller orientation ios6

I've had a lot of trouble with how iOS6 handles Orientation, hopefully this is what you're looking for.

Create an extension of UINavigationController and call it "UINavigationController+autoRotate".

Put this in your UINavigationController+autoRotate.h:

#import <UIKit/UIKit.h>

@interface UINavigationController (autoRotate)

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation;
-(BOOL)shouldAutorotate;
- (NSUInteger)supportedInterfaceOrientations;

@end

Put this in UINavigationController+autoRotate.m:

#import "UINavigationController+autoRotate.h"

@implementation UINavigationController (autoRotate)

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return [self.topViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}

- (BOOL)shouldAutorotate
{
return [self.visibleViewController shouldAutorotate];
}

- (NSUInteger)supportedInterfaceOrientations
{
if (![[self.viewControllers lastObject] isKindOfClass:NSClassFromString(@"ViewController")])
{
return UIInterfaceOrientationMaskAllButUpsideDown;
}
else
{
return [self.topViewController supportedInterfaceOrientations];
}
}

@end

For Views that you DO NOT want to rotate, add:

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

- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}

- (BOOL)shouldAutorotate
{
return NO;
}

And for Views you DO want to rotate:

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

- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAllButUpsideDown;
}

- (BOOL)shouldAutorotate
{
return YES;
}

In your App's delegate, add:

- (NSUInteger)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window
{
return UIInterfaceOrientationMaskAllButUpsideDown;
}

Why implement

shouldAutorotateToInterfaceOrientation:

when
that's a deprecated method? And is "shouldAutoRotate" spelled that way (with upper-case R) in your actual implementation? – Hot

@HotLicks To ensure compatibility with iOS5, but thanks - shouldAutorotate was a typo – mmackh Dec

Yes, but you're adding shouldAutorotateTo... to the nav controller and having it look up the stack. For iOS5 the top of the stack would
be consulted without this added code. It seems unnecessary (and unnecessarily confusing). – Hot

FWIW, the default implementation of supportedInterfaceOrientations returns 26 -- all orientations except upside-down. So the method
need not be added to VCs for which that default is sufficient. – Hot

Really helpful. It helped me and saved my time and did within very less time. – AppAspect Apr

I recommend you to NOT create a category on UINavigationController to override those methods. Categories are not aimed to do that, and there is no warranty that your code is going to be loaded instead of Apple's one (even if actually that works). I advise you
to create a subclass of UINavigationController, and override those methods in it.

From the 6.1 Beta release notes: Landscape-only apps that invoke a portrait-only view controller (such as the Game Center login screen)
will cause the app to crash. Workaround: Apps should provide the delegate method application:supportedInterfaceOrientationsForWindow: and ensure that portrait is one of the returned mask values. When a UINavigationController is involved, subclass the UINavigationController
and override supportedInterfaceOrientations. – mmackh Nov
