I have a UINavigation base app in which I was supporting all orientations for some view controller but not for all using this code
#interface UINavigationController (Autorotation)
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation;
#end
#implementation UINavigationController (Autorotation)
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
if ([self.visibleViewController isKindOfClass:[MWPhotoBrowser
class]] || [self.visibleViewController
isKindOfClass:[ZoomPictureViewController class]]) {
return YES;
}
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
#end
It was working great but not working in IOS6. I have set all four orientations supported in my projects plist file.
Help if anyone has found some work around for.
Here is the link for apple documentation Read it :)

Hope this will help.
In ios 6 there are new methods for orientation use these methods in your navigation controller subclass
-(BOOL) shouldAutorotate
{
return YES;
}
-(NSUInteger) supportedInterfaceOrientations{
if ([self.visibleViewController isKindOfClass:[YourClass class]] ||[self.visibleViewController isKindOfClass:[YourClass class]]) {
return UIInterfaceOrientationMaskAll;
}
return UIInterfaceOrientationMaskPortrait;
}

I used this code to block the rotation before ios 7 (i was also using xibs, now storyboard)
- (BOOL)shouldAutorotate {
return NO;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationPortrait;
}
now that i migrated to storyboard and ios7 it is not working, my view is still rotating.
UPDATE:
I solved this by adding this code to the delegate, now my previous code works like charm
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
NSUInteger orientations = UIInterfaceOrientationMaskPortrait;
if (self.fullScreenVideoIsPlaying) {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
else {
if(self.window.rootViewController){
UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presentedViewController supportedInterfaceOrientations];
}
return orientations;
}
Atrik's code worked. Here is a more complete solution which allows locking and unlocking of portrait-mode-only even with the use of UINavigationController
appdelegate .h
#property (nonatomic) BOOL screenIsPortraitOnly;
appdelegate .m
#pragma mark - View Orientation
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
NSUInteger orientations = UIInterfaceOrientationMaskPortrait;
if (self.screenIsPortraitOnly) {
return UIInterfaceOrientationMaskPortrait;
}
else {
if(self.window.rootViewController){
UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presentedViewController supportedInterfaceOrientations];
}
return orientations;
}
}
For all view controllers where I need Portrait Lock
If you haven't used a subclass which has the app delegate imported then don't forget to import the delegate. For most view controllers I use a subclass of UIViewController which at least does importation.
#import "AppDelegate.h"
I use this for all portrait locked viewcontrollers.
-(void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:true];
[self portraitLock];
}
-(void) portraitLock {
AppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
appDelegate.screenIsPortraitOnly = true;
}
#pragma mark - interface posiiton
- (NSUInteger) application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL) shouldAutorotate {
return NO;
}
ViewDidLoad runs before viewDidAppear so I run this in my subclass of UIViewController to unlock all screens. The viewWillAppear with the lock method is used only in the cotrollers which I need to lock the screen.
- (void)viewDidLoad
{
[super viewDidLoad];
[self portraitUnLock];
}
-(void) portraitUnLock {
AppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
appDelegate.screenIsPortraitOnly = false;
}
If you only want in landscape mode then you can do it with xcode project setting
go to Target > summary > support interface orientations
Or you can do a code
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations.
return (UIInterfaceOrientationIsLandscape(interfaceOrientation));
}
In XCode 5, which is required to be used for iOS7 development, you can go to your target and under Deployment Info uncheck everything except Portrait for device orientation.
If you don't want your app to rotate at all (no matter which view is active), you can click on your project in the Xcode sidebar, scroll down, and deselect Landscape Left and Landscape Right.
I have UITableViewController in which on one tab is UINavigationViewController. UINavigationController root view controller is UITableViewController, and when clicked on cell, UIViewController appears which has to be locked in Landscape.
I want every Controller to be locked in Portrait, except the mentioned UIViewController that must be locked in Portrait.
I have tried the following:
CustomTabBarController.m:
#import "CustomTabBarController.h"
#implementation CustomTabBarController
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// You do not need this method if you are not supporting earlier iOS Versions
return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}
- (BOOL)shouldAutorotate{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations{
return [self.selectedViewController supportedInterfaceOrientations];
}
#end
CustomNavigationController.h:
#import "CustomNavigationController.h"
#implementation CustomNavigationController
-(NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
-(BOOL)shouldAutorotate
{
return YES;
}
#end
And in UIViewController that must be locked in to Landscape, I have put:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight));
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
-(BOOL)shouldAutorotate
{
return YES;
}
But it doesn't work, I can rotate it to Landscape and it will stay locked in Landscape, but I want it to appear automatically in Landscape.
Any suggestions?
I had a big problem in the past with UITabBarController not respecting my supported interface orientations of displayed view controllers.
I solved the problem by sub-classing UITabBarController and capturing whenever an item was selected. I'd then call down to the view controller myself, ask it what the supported orientations are and force a rotation myself if needed. I would also call down to the selected view controller on rotations to set/change my supported orientations.
I implemented the UITabBarDelegate and used didSelectItem to capture tab switches. I'm not sure if there is a better way to do it now.
Try to override method
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
Try with the method to block some orientations for a particular window:
– application:supportedInterfaceOrientationsForWindow:
How to use the following methods to support interface orientation in iOS 6.0:
shouldAutorotate
supportedInterfaceOrientations
preferredInterfaceOrientationForPresentation
As "shouldAutorotateToInterfaceOrientation" is deprecated in iOS 6.0.
Please provide code snippets to support your answers.
Thanks.
Deprecated method in iOS 5:
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
Replacement in iOS 6 and equivalent of this deprecated iOS 5 method above:
- (BOOL) shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight;
}
Hope this helps.

By the way, your settings on your Xcode project settings now take precedence.
Make sure that you set the "Supported interface orientations" array properly in your project's settings.
That was the issue for me. Removed the undesired ones and my app worked like it did when I compiled with Xcode 4.4.1
My app has an instance of a custom UINavigationController subclass, that presents several view controllers, all in portrait only, except when playing a video, in which case I want to additionally allow both landscape orientations.
Based on #uerceg 's answer, this is my code.
First, I enabled Portrait, Landscape Left and Landscape right in Xcode -> Target -> Summary.
In the UINavigationController subclass's implementation, I #import'ed <MediaPlayer/MediaPlayer.h>.
Then I implemented these methods:
// Autorotation (iOS <= 5.x)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if ([self modalViewController] && [[self modalViewController] isKindOfClass:[MPMoviePlayerController class]]) {
// Playing Video: Anything but 'Portrait (Upside down)' is OK
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
else{
// NOT Playing Video: Only 'Portrait' is OK
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
}
// Autorotation (iOS >= 6.0)
- (BOOL) shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
NSUInteger orientations = UIInterfaceOrientationMaskPortrait;
if ([self modalViewController] && [[self modalViewController] isKindOfClass:[MPMoviePlayerController class]]) {
// Playing Video, additionally allow both landscape orientations:
orientations |= UIInterfaceOrientationMaskLandscapeLeft;
orientations |= UIInterfaceOrientationMaskLandscapeRight;
}
return orientations;
}
NicolasMiari's code worked for me. A little different spin I had a UITabBarController that presented UINavigationControllers and I was using StoryBoards. The UITabBarController's subclass's implementation is exactly the same and be patient with the Class selection for the Tab Bar Controller in Story Boards. It isn't immediately available even after building.

There are a number of examples and suggestions in the above threads relating to supporting interface orientation changes on iOS6, the two threads related to issues with game centre views but should be enough to get you started.
You should also check the iOS6 release notes under UIKit, unfortunately I can't give you a direct link since I'm new.
Avoiding posting code here due to NDA
Hope that helps
our app got rejected, becouse the app does not rotate in upside down orientation.
so we have an tabbar App, adding this code to all tabs...
shouldAutorotateToInterfaceOrientation
makes no sense, add this code to a Appdelegate doesn't helps, what we do wrong?
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
UITabbarcontroller is a subclass of UIViewcontroller. To solve you problem just subclass or add a category for you UITabbarcontroller implementing:
#interface UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
#end
#implementation UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
#end
If you want to make the tabbar only rotate to portrait and upside down just use th following code instead
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait ||
interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}
Make sure that each UIViewController implements
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
I have QuickLook (QLPreviewController) almost working how I want it, but because of the images characteristics I don't want it to rotate into portrait orientation.I have it configured in the "shouldAutoRotateToInterfaceOrientation" method to only return yes for landscape rotations (see code below for details) but it is still rotating to portrait.
Note: The shouldAutoRotateToInterfaceOrientation is a direct copy that is used in all of my view controllers for this project and it is working in the other view controllers.
//
// documentViewer.m
//
#import "DocumentViewer.h"
#implementation DocumentViewer
#synthesize documents;
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft)
return YES;
else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight)
return YES;
else
return NO;
}
- (void)viewDidLoad {
[super viewDidLoad];
}
//-(void)viewWillAppear:(BOOL)animated {
//
// self.userInteractionEnabled = YES;
//}
//Nessary for Enabling User Interaction
- (BOOL)canBecomeFirstResponder {
return YES;
}
-(void) createList:(NSString *) document {
documents = [[NSArray arrayWithObjects:document, nil] retain];
}
-(NSInteger) numberOfPreviewItemsInPreviewController: (QLPreviewController *) controller {
return [documents count];
}
- (id <QLPreviewItem>) previewController: (QLPreviewController *) controller previewItemAtIndex: (NSInteger) index {
return [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:[documents objectAtIndex:index] ofType:nil]];
}
#end
In AppDelegate.m replace
return UIInterfaceOrientationMaskAll;
with
return UIInterfaceOrientationMaskLandscape;
just like this:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
return UIInterfaceOrientationMaskLandscape;
}
According to the ViewController Programming Guide for iOS, the autorotation is roughly controlled by the ViewController that was most recently made visible.
In your case that's probably the QLPreviewController itself, not your DocumentViewer. (And you say that the latter's shouldAutorotateToInterfaceOrientation: isn't called, which is consistent with this hypothesis).
So the autorotation is controlled by the shouldAutorotateToInterfaceOrientation: method of QLPreviewController, which in a little experiment of mine seems to allow everything but upside-down orientation.
So what you can do is define a subclass of QLPreviewController that only overrides shouldAutorotateToInterfaceOrientation: the way you did in DocumentViewer and use this subclass instead of the original QLPreviewController.
LandscapeOnlyQLPreviewController.h:
#import <QuickLook/QuickLook.h>
#interface LandscapeOnlyQLPreviewController : QLPreviewController {
}
#end
LandscapeOnlyQLPreviewController.m:
#import "LandscapeOnlyQLPreviewController.h"
#implementation LandscapeOnlyQLPreviewController
- (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation) interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
#end
I never did find a good answer, so I ended up just using a UIWebView.
But I'm still looking.
Try this:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
