I would like to set different rules for the different viewControllers in my apps, not a single rule across all views (like you can define in Target-Summary).
For instance I have several views I would like my first few views to only appear in portrait view, however in my last view I would like the user to be able to change between protrait and landscape... I was woundering how I could do this.
Also I have read issues where the user navigates to a view while in landscape and the view appears landscape when it should be portrait and will not change untill the user rotates the device, I would like to avoid this if possible...
So my question is how can I allow different UIViewController Orientations depending on which view the user is in.
This will depend on whether you target iOS 5 or iOS 6.
iOS 5:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation {
if ((orientation == UIInterfaceOrientationPortrait) ||
(orientation == UIInterfaceOrientationLandscapeLeft))
return YES;
return NO;
}
iOS 6:
Set your default supported orientations in the App Summary and then in VC's you want to be different:
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft;
}
Apple Documentation for this HERE
See these questions for more info:
shouldAutorotateToInterfaceOrientation not being called in iOS 6

Hi guys i know this question might be asked before as well , so if u could point out right question to refer to that would be great .
Problem - in my info.plist i have only 2 orientation allowed i.e Portrait ,UpsideDown
and every viewController abides to above orientation .
But for one particular viewController i want whole 360 degree orientation .
this viewController is presented modally with style
UIModelPresentationStyle.FullScreen
And to support all orientation in ViewController ,
i have overridden relevant delegate methods as well
ShouldAutorotate is returning -> Yes ,
PreferredOrientationForPresentation is returning -> UIInterfaceOrientation.LandscapeLeft ;
GetSupportedInterfaceOrientation is returning -> UIINterfaceOrientationMask.all
When this ViewController loads i am getting landscapeLeft as expected , when i rotate the iPad, i get portrait mode as well ,
but now i am not able to return back to landscape mode anymore .
Any reason for that???
in my info.plist i have only 2 orientation allowed
Well, that's the problem. You're doing this wrong. The Info.plist should list every orientation that the app can ever have. Your top-level view controllers can then limit their own orientations.
My app supports only landscape mode. when i am trying to open image picker within the app it shows an exception which is as follows:
"Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES"
I had tried to make false value for shouldAutorotate but didn't succeed. I am stuck with this. Any one have any help regarding this?
If you like to use UIImagePickerController as lanndscape mode , instead of
- (BOOL)shouldAutorotate
{
return NO;
}
use this
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscape;
}
but make sure to check this as:
I want to create an iOS app that can only work on landscape-view mode.
I Googled how to do that, and end up with supportedInterfaceOrientations method
Here's my attempt:
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft;
}
I tried to put the above code on viewController.m and AppDelegate.m, but it didn't seem to work
Thanks, any opinion will be much appreciated
You don't need to write any code to run app which supports landscape mode only. Just select app target and uncheck portrait and portrait upside down orientation and make sure landscape orientation is checked.
It seems as though you want to programmatically change the orientation of your application. This can be done by any ViewController by implementing one method.
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
That should force the view to auto-rotate in the direction you want it.
When you use -supportedInterfaceOrientationForPresentation it simply states that the returned interfaces can be used, not necessarily that they should be used.
When you use -preferredInterfaceOrientationForPresentation it says that this is orientation that I want, and that the ViewController should switch to it.
Problem:
If user is not logged into GameCenter account - GameCenter authentication view is launched in portrait mode (in ios 5 there were a modal dialog) asking to log in. But if I disable Portrait mode in xcode (Project Summary) or in supportedInterfaceOrientationsForWindow: (as my app supposed to run in landscape mode ONLY) I get:
Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES'
If I enable Portrait for ipad/iphone (and/or comment out supportedInterfaceOrientationsForWindow:) it works without crash, but I don't want portrait mode to be enabled.
While writing this question and experimenting with code, it seems that I've found a solution:
enable all orientations in project summary and remove application:supportedInterfaceOrientationsForWindow.
Add this code to ViewController:
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
Now it works seamlessly.
Add to app delegate:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)w {
return (NSUInteger)[application supportedInterfaceOrientationsForWindow:w] | (1<<UIInterfaceOrientationPortrait);
}
I have found that the problem is coming from the Game Center in my case. When in the simulator I do not have the Game Center initialized yet, it would like to pop up the login view, but in portrait mode. Once it is reaching this point it crashes if I disallowed portrait orientation. Strange bug in the OS as Game Center should take the allowed orientations only to be inline with our intention of landscape user interface.
I do not have the solution yet, but I will post if I find it.
I had the same issue as you and I fixed it with a kinda, ugly work around, basically I have a global variable in my app that I use to choose what the valid interface orientations are. In the
- (NSInteger)application : (UIApplication *)supportedInterfaceOrientationsForWindow:(UIWindow *)window{
if(orientationIndicator == 1){
return UIInterfaceOrientationMaskAllButUpsideDown;
}
else if(orientationIndicator == 2){
return UIInterfaceOrientationMaskLandscape;
}
}
To declare the global variable put this in your appDelegate.m file :
int orientationIndicator = 1;
To import the global variable use :
extern int orientationIndicator;
Then you can change the value of orientation indicator and it will allow you to run in different interface types. So what I did was I start by making the orientationIndicator = 1. When you authenticate a player and initiate the login view controller set the orientation indicator to 2. When you dismiss the view (authenticate the player) then you can change it back to 1.
This is a slimy work around but it has worked for me.
Hope this helps!
Catching the exception appears to work just fine for me:
#try {
[rootNavigationController pushViewController:viewController animated:YES];
}
#catch (NSException *exception) {
//somehow, catching this exception just allows the view controller to be shown?
}
In iOS 6.0, the exception is thrown, but if you catch it then the viewController will still be shown and GameCenter will behave as expected in landscape orientation.
An alternate solution is just to target iOS 6.1 and above, as Apple fixed the bug by that release.
In IOS 3.2 I was able to display my UISplitViewController side by side like in landscape mode.
In IOS 4.2 the RootViewController (MasterView) is not showing up in portrait mode. Does anyone know if we need to display the rootviewcontroll in a popover? Can we display it side by side like how it is in landscape mode?
I want to avoid having to click on a button to show the masterview (when in portrait mode)
In that case, you can skip the splitviewcontroller and create only view base application where you could manually control the UI.
on viewDidAppear you can do
[splitViewController setHidesMasterViewInPortrait:NO];
It works even though you get a warning. I think you can create category with a custom splitviewcontroller to get rid of the warning.
2.Otherwise you can do something like
on the viewWillAppear, you can do something like
if (self.interfaceOrientation == UIInterfaceOrientationPortrait || self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
UIViewController *master = [[splitViewController.viewControllers objectAtIndex:0];
UIViewController *detail = [[splitViewController.viewControllers objectAtIndex:1];
[splitViewController setupPortraitMode:master detail:detail];
}

I used setHidesMasterViewInPortrait:NO and it did work on the pre-5.0 releases, and even got into the apple store once. But the next time I updated the app, they rejected it because I used a hidden API. I am still searching for a way to make this work.
