ios6rotations
Sorry guys for asking the question about screen rotation in iOS 6 but this is really a pain in the ass..and I still can't understand it completely - for some reason it behaves differently under certain circumstances.
I have the following simple hierarchy of views in my test app:
What I'm trying to achieve is - to keep blue controller in landscape only and red one is only in portrait.
I have a subclass of UINavigationController with such code inside:
#implementation CustomNavController
- (BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
- (NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
#end
In my blue controller I implemented this:
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
And in red controller this:
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
Now I have the following behavior:
App started in landscape (OK)
When I press the button my red controller pushed in landscape too (this is not ok because it must be shown in Portrait)
It successfully rotates to portrait but not backward to landscape
If I leave the red controller in Portrait mode my blue controller (which is restricted to landscape) shows in Portrait mode.
P.S.
All my rotation methods(posted above) are getting called normally.(by the way why do these methods getting called so many times per screen transition - 5-6 times)
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation does not getting called with pushing
All(except portraitUpsideDown) orientations are included in plist.
The question is - how to force rotation to supported orientation in each controller?
I suggest you to post here (as answers) any 100% working code to handle rotations in ios6 (for example if you have some for iPad with SplitController) - I'll keep this question in favorites to have all in one place when I need to handle some specific situations. Cheers!
ADDED:
Please do not post this as answer from landscape to portrait I hope that there'
s more elegant way to do it.
Using -[UIDevice setOrientation:] is a private API, and will get your application rejected. See this question.
What you ask is not possible using public API and is also not recommended from HIG standpoint. What is supported and you should implement, is modal presentation of the different view controllers with different supported interface orientation. This is why the default implementation of UINavigationController is to always rotate; it assumes all view controllers have the same supported interface orientations.
Take for example video playback on iPhone. Open the video apps (that comes with iOS). The root view controller only supports portrait orientation. However, start a video, and a modal view controller pops up which only supports landscape interface orientations. This seems exactly the behavior you wish to achieve.
This is why preferredInterfaceOrientationForPresentation is not called. preferredInterfaceOrientationForPresentation only gets called when using presentViewController:animated:.
A small gotcha, if you require a navigation bar in each stage of your scene, you will need to enclose each modal view controller with a navigation controller. You can then pass the required data in prepareForSegue: by accessing topViewController of the navigation controller object in the segue.
Here is an example project which behaves correctly according to your requirements (or at least will give you ideas how to implement):
http://www.mediafire.com/?zw3qesn8w4v66hy
My two cents worth.
You can present an empty transparent modal view quickly then dismiss it, maybe on ViewDidLoad: or viewWillAppear: on your ViewController and ViewControllerSecond class as a quick workaround.
Also, in storyboard, you can set ViewController class orientation to landscape visually.
use this line for programmatically change orientation... work 100%
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];
and also when you add this line at that time one warning appear and for remove this warning just add bellow code on you implementation file.. at the top.
#interface UIDevice (MyPrivateNameThatAppleWouldNeverUseGoesHere)
- (void) setOrientation:(UIInterfaceOrientation)orientation;
#end
and after that in bellow method just write this code if required..
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return your supported orientations
if (currentMainView==blueOne) {
return toInterfaceOrientation== UIInterfaceOrientationPortrait;
}
}
I have a similar situation in one of my apps (although do note that I am not using UINavigationController).
Change the shouldAutorotate methods in both of your viewControllers:
//in blue (landscape only)
-(BOOL)shouldAutorotate{
if (UIInterfaceOrientationIsLandscape(self.interfaceOrientation)) {
return YES;
}
else {
return NO;
}
}
//in red (portrait only)
-(BOOL)shouldAutorotate{
if (self.interfaceOrientation == UIInterfaceOrientationPortrait) {
//note that UIInterfaceOrientationIsPortrait(self.interfaceOrientation) will return yes for UIInterfaceOrientationPortraitUpsideDown
return YES;
}
else {
return NO;
}
}
Keep the supportedInterfaceOrientations methods the same.
#pragma mark- Orientation Delegate Method:
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{ Orientation = [UIApplication sharedApplication].statusBarOrientation;
if (Orientation == UIInterfaceOrientationLandscapeLeft || Orientation == UIInterfaceOrientationLandscapeRight)
{
// self.scrollView.contentOffset = CGPointMake(self.view.bounds.size.width,1200);
[scrollView setScrollEnabled:YES];
[scrollView setContentSize:CGSizeMake(768, 2150)];
}else if (Orientation == UIInterfaceOrientationPortrait || Orientation == UIInterfaceOrientationPortraitUpsideDown)
{
[scrollView setScrollEnabled:YES];
[scrollView setContentSize:CGSizeMake(768, 1750)];
}
}
In order to use navigation with orientation together, you should take a bunch of viewcontrollers like an array.
After that checkout following methods,
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
this changes in your methods will help you a lot.
Enjoy Programming!

I have a strange problem with UIInterfaceOrientation. In my project there are many different views, some of them should rotate in landscape mode, and some of them should not. The problem is that all the view which were not created using Storyboard and in which only the UIInterfaceOrientation portrait is enabled this works fine and the view does not rotate, instead all the views created using the Storyboard, even if the UIInterfaceOrientation landscape mode was disabled they keep rotating. In my Xcode project setting those checks are enabled and I cannot change them:
How can I completely disable the device rotation in all the different views? [Storyboard or not].
This is the code I use to disable the device orientation in all the storyboard view controller, but it does not work:
- (BOOL)shouldAutorotate {
return NO;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
Try this code maybe it will work for you.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientationMask)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationMaskPortrait);
}
The solution was to assign a UINavigationController class to the UINavigationController in the Storyboard file and to place this code in his .m file:
- (BOOL)shouldAutorotate {
return NO;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationPortrait;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return UIInterfaceOrientationIsPortrait(toInterfaceOrientation);
}
Please, check if in your project .plist there are more than one item for orientation or something strange. I sometimes have found that orientation has different values in plist or duplicated keys.
Hope it helps
My entire app is locked in portrait orientation but when a video is played I wanna allow all orientations just for the video playback.
Storyboard:
TabBarController --> NavigationController --> MyVideosController --> MyVideoPlayerController
This is one of many I've tried:
Allow One View to Support Multiple Orientations While Others Do Not iPhone
The problem is that I never even reach into this method in my MyVideoPlayerController.m:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
In my experience just about every suggestion you will find on here won't work for you. What you are going to want to do is (if you are using storyboards) add another navigation controller and a view controller. You will push the 2nd navigation controller modally and lock it to the orientation you desire. This way your video player can "pop up" and be in the orientation(s) you want.
Its really annoying.
An alternative (which I don't really suggest) is that you can turn on AutoLayout and perhaps try the IOS6 version.
For iOS-6 , I have done this , it is running greatly
(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft;
}
(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
try this code, add it to your class it's working for me:
#pragma mark - Orientation
- (BOOL)shouldAutorotate {
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
I am using UINavigationController in my application and my first controller called A and it is strict to portrite only and there is a button in my A controller.Once I click on the button I am creating instance to the another view controller called B. After creating the instance for B I am presenting modally using below method
[self presentViewController:BInstance animated:YES completion:^{
NSLog(#"completed");
}];
My B controller can able will support all the orientations, this is expected, till the ios5.1 and earlier versions. Now I am trying to run my project on the ios6 using Xcode4.5 it is not getting rotated I am looking forward to solve the issue I found some of the blogs about shouldAutorotateToInterfaceOrientation: method got deprecated from the latest ios6. I used alternative also
-(BOOL)shouldAutorotate{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskAll;
}
But still there is not much expected results.
Question: What makes my B controller will work for all orientations even my Parent A works only for portrite.
Thanks In advance All your suggestions/advice useful on this.
First of all, in AppDelegate, write this. THIS IS VERY IMP
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return (UIInterfaceOrientationMaskAll);
}
Then, For UIViewControllers, in which you need only PORTRAIT mode, write these functions
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskPortrait);
}
For UIViewControllers, which require LANDSCAPE too, change masking to All.
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskAllButUpsideDown);
//OR return (UIInterfaceOrientationMaskAll);
}
Now, if you want to do some changes when Orientation changes, then use this function.
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
}
I want to support iOS 6 rotation. Trouble is, I've been looking through a lot of documentation and stack overflow questions but have not found any even slightly in depth solutions. I've only seen that I should add these two methods to my view controller classes - however, if I'm not mistaken, they do not operate in the same way as the pre iOS 6 methods:
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll; // use what is appropriate for you.
}
My app currently rotates in pre-iOS6 using the following code. Note that I use the interface orientation parameters to determine whether or not I'm going to push my view Controller. How do I implement this in the iOS 6 rotation delegates?
-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
UIInterfaceOrientation toOrientation = self.interfaceOrientation;
if ( self.tabBarController.view.subviews.count >= 2 )
{
UIView *tabBar = [self.tabBarController.view.subviews objectAtIndex:1];
if(toOrientation != UIInterfaceOrientationLandscapeLeft && toOrientation != UIInterfaceOrientationLandscapeRight)
{
CUSTOM_DEBUG_LOG("\n\nRotated back to Portrait");
tabBar.hidden = FALSE;
}
}
}
- (void) willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration
{
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
CUSTOM_DEBUG_LOG("\nView going landscape");
ScrollViewController *s = [[ScrollViewController alloc] initWithNibName:#"ScrollViewController" bundle:nil];
[self.navigationController pushViewController:s animated:NO];
[s release];
self.tabBarController.tabBar.hidden = YES;
self.navigationController.navigationBar.hidden = YES;
}
}
Checkout this and this SO discussion.
[EDIT]
Yes the methods you mentioned aren't deprecated in iOS 6.0 and they will continue working. It's just the way Auto Rotation works have been changed. So far it was view controllers responsibility to decide whether they rotate or not but now RootViewController will decide whether their children should rotate or not. If you don't have rootviewcontroller setup then you have to add it to window and then put shouldAutoRotate and supportedInterfaceOrientations methods in the rootviewcontroller.
Parent Views now handle rotation in iOS 6. Subclass your nav controllers and add a bool
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait; // your rotation here
}
I may not have implemented the iOS6 rotation code correctly when I first posted the question.
I incorrectly thought that the willAnimateRotationToInterfaceOrientation function was deprecated in iOS6, leading me to believe that there was a new iOS rotation delegate with an orientation parameter. Turns out this is not the case, so my app sort of works.
The code I plugged into my app was just this:
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight);
}
If you are using a UINavigationController, override shouldAutomaticallyForwardRotationMethods = YES property.
Then like Mark S said, also override shouldAutorotate and supportedInterfaceOrientations for the children VCs.
I'm having trouble figuring out how to handle device rotation on iOS 6. I have three things that need to change separately when the device is rotated.
I have a parent UIViewController that handles multiple sub UIViewControllers or UINavigationControllers (Its basically a custom UITabBarController). I do not want this to rotate.
Each of these sub view controllers, will either rotate or not rotate depending on its own settings. (I want some to rotate and some to not).
In the tab bar, I want each tab icon (a UIView) to rotate to the orientation.
How would I go about making this happen in iOS 6, I got everything working in iOS 5.
Here is what I have so far:
In the parent UIViewController:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return UIInterfaceOrientationPortrait;
}
- (BOOL)shouldAutorotate
{
return NO;
}
- (BOOL)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
In the sub view controllers:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return YES;
}
- (BOOL)shouldAutorotate
{
return YES;
}
- (BOOL)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
There's a bit more to this to support iOS6 correctly. The iOS 6 Release Notes sketch things out:
https://developer.apple.com/library/ios/#releasenotes/General/RN-iOSSDK-6_0/_index.html
This bit might be useful:
For compatibility, view controllers that still implement the shouldAutorotateToInterfaceOrientation: method do not get the new autorotation behaviors. (In other words, they do not fall back to using the app, app delegate, or Info.plist file to determine the supported orientations.) Instead, the shouldAutorotateToInterfaceOrientation: method is used to synthesize the information that would be returned by the supportedInterfaceOrientations method.
But you should also take a look at Session 236 from WWDC 2012 - The Evolution of View Controllers.
If you want to support different orientation in navigation stack, you must subclass UINavigationController first and override supportedInterfaceOrientations.
- (NSUInteger)supportedInterfaceOrientations
{
//I want to support portrait in ABCView at iPhone only.
//and support all orientation in other views and iPad.
if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone)
{
// find specific view which you want to control.
if ([[self.viewControllers lastObject] isKindOfClass:[ABCView class]])
{
return UIInterfaceOrientationMaskPortrait;
}
}
//support all
return UIInterfaceOrientationMaskAll;
}
