I have following ViewControllers:
InformationViewController and cardViewController.
How can i make sure that informationViewController is in portrait mode and cant be rotated.
Then cardViewController should be in landscape mode and cant be rotated.
How can i implement this in each viewController. i've at the moment activated protrait, landscape right and left in General
In Information view controller
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
And in card view controller
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
Note: Please be sure in project general setting tick the both portrait and landscape modes in device orientation (Deployment Info)
In informationViewController:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
In cardViewController:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscape);
}
Have a look at my answer to this question:
Force controllers to Change their orientation in Either Portrait or Landscape
(But don't use the deprecated methods. There are newer methods available which work either.)
It is easy to limit the view controllers to certain orientations. But see the other answer for how to force the device to actually rotate.
Without that trick: If a portrait only view controller becomes visible while the device is in landscape, then it will be displayed in landscape regardless how you limit its supported orientations.

How to use MPMoviePlayerController to play video in landscape orientation in iOS all across the Application. I am using the MPMoviePlayerController in many viewControllers of my app and I want all the MKMoviePlayerController torun only in landscape mode irrespective of the orientation of the parent view controller from where this ViewController is called.
Enable landscape orientation in your project settings.
Subclass UIViewController and in your new subclass (e.g. MyViewController) add these callbacks:
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationPortrait;
}
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
Make all your view controllers of type MyViewController.
In the views you want to force landscape override those methods with:
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationLandscapeRight;
}
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
I have five view controllers and In Project Target Device Orientation I have enabled Portrait ,Landscape Left and Landscape Right. Now I want 4 view controllers out of 5 view controllers Stay in Portrait mode (Not Rotate into landscape left and landscape right) and only one view controller rotate in all modes(Portrait,landscape left,landscape right). So How can do this please tell .
Implement -(NSUInteger)supportedInterfaceOrientations for each of your ViewControllers and specify which interface orientations each controller should support.
Edit
Assuming that you have a separate implementation for each of your ViewControllers, implement -(NSUInteger)supportedInterfaceOrientations and -(BOOL)shouldAutorotate in each of your implementations.
For example
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscape;
}
will ensure that your view controller supports all landscape modes. Combine this with
-(BOOL)shouldAutorotate{
return YES;
}
and your display will "flip" over when rotated.
Use the enum UIInterfaceOrientationMask to adjust which orientations are supported and try different combinations of this along with a YES/NO return value to -(BOOL)shouldAutorotate until you get the behaviour you want.
First of all, in AppDelegate, write this.
- (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
{
}
NOTE Please :-
A lot depends on with which controller is your UIViewController embedded in.
Eg, If its inside UINavigationController, then you might need to subclass that UINavigationController to override orientation methods like this.
subclassed UINavigationController (the top viewcontroller of the hierarchy will take control of the orientation.) did set it as self.window.rootViewController.
- (BOOL)shouldAutorotate
{
return self.topViewController.shouldAutorotate;
}
- (NSUInteger)supportedInterfaceOrientations
{
return self.topViewController.supportedInterfaceOrientations;
}
From iOS 6, it is given that UINavigationController won't ask its UIVIewControllers for orientation support. Hence we would need to subclass it.
My app has this main structure: UITabBarController, where each tab hosts a UINavigationController that pushes views according to user interaction. Almost all the app is portrait orientation only, except a few specific sections.
The behavior I want is to have landscape orientation when I push one of the sections (let's say a map). In that map, the user can go back to portrait orientation. When he goes back in the main menu, he should go back to portrait orientation (landscape should not be allowed here). I don't mind if he is temporarily in landscape.
Here's some code from my UITabBarController subclass:
- (BOOL)shouldAutorotate
{
return [self.selectedViewController shouldAutorotate];
}
- (NSUInteger)supportedInterfaceOrientations
{
return [self.selectedViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [self.selectedViewController preferredInterfaceOrientationForPresentation];
}
I use the same code in my UINavigationController, and in the specific menu, I have this:
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
- (BOOL)shouldAutorotate
{
if (!UIInterfaceOrientationIsPortrait([[UIDevice currentDevice] orientation]))
return NO;
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
The behavior works almost all the time. When the orientation of the menu is landscape and the user rotates his device, he goes back to portrait, but can't go back to landscape.
My issue is: once in a while, the status bar will rotate, but not the view controller. (see picture) Each time, shouldAutorotate is called and returns the correct value (ie. it returns YES but does not autorotate).
I know this is stretching the SDK, but I'd love to make this work all the time. Any hints?
I have a flag and user will set it from setting. If set to No only portrait orientation will be allowed. If flag is YES then both portrait as well as landscape will be allowed.
in ios 5 and below
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
//[image_signature setImage:[self resizeImage:image_signature.image]];
if(flag == YES)
return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight || toInterfaceOrientation == UIInterfaceOrientationPortrait);
else
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
But in ios 6 and above above method deprecated.
I was trying
-(BOOL)shouldAutorotate
- (NSUInteger)supportedInterfaceOrientations
But no success.
Please help me.
EDIT
I tried this.
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
NSLog(#"preferredInterfaceOrientationForPresentation");
return UIInterfaceOrientationMaskPortrait;
}
- (NSUInteger)supportedInterfaceOrientations
{
NSLog(#"supportedInterfaceOrientations");
return UIInterfaceOrientationMaskPortrait;
}
But only supportedInterfaceOrientations is called only once. When I change orientation of simulater both methods not calling.
shouldAutorotateToInterfaceOrientation:
Returns a Boolean value indicating whether the view controller supports the specified orientation.
(Deprecated in iOS 6.0. Override the supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation methods instead.)
(http://developer.apple.com/library/ios/documentation/uikit/reference/UIViewController_Class/DeprecationAppendix/AppendixADeprecatedAPI.html)
So the two method you can use in newer versions are:
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
http://developer.apple.com/library/ios/documentation/uikit/reference/UIViewController_Class/Reference/Reference.html#//apple_ref/occ/instm/UIViewController/preferredInterfaceOrientationForPresentation
and
- (NSUInteger)supportedInterfaceOrientations
This method uses the following Bit Masks:
UIInterfaceOrientationMaskPortrait
UIInterfaceOrientationMaskLandscapeLeft
UIInterfaceOrientationMaskLandscapeRight
UIInterfaceOrientationMaskPortraitUpsideDown
UIInterfaceOrientationMaskLandscape
UIInterfaceOrientationMaskAll
UIInterfaceOrientationMaskAllButUpsideDown
http://developer.apple.com/library/ios/documentation/uikit/reference/UIViewController_Class/Reference/Reference.html#//apple_ref/occ/instm/UIViewController/supportedInterfaceOrientations
Update:
OK, I'm not sure why it isn't working for you.
I've just created a demo app to replicate what you're trying to do:
(use right click > copy image url and open in new browser tab to see bigger picture)
When the orientation flag is NO, the button text shows "Landscape Denied", and rotating the device in simulator doesn't cause interface to rotate, as expected:
However after clicking on the button to allow landscape orientation, rotating the simulator device actually changes the orientation of the interface, as expected:
You don't have any other orientation delegate method in another root view controller overriding your current view controller's orientation delegate methods do you?
Also, I don't know if using Auto Layout interferes or not, I tend not to use it. In my View inside my XIB file, I selected the "View" object and then in the inspector, I untick "Use Auto Layout". My example project screenshot above is NOT using auto layout.
Update 2:
Alright, I found this solution which worked with navigation controller as root view controller of window (put this in your AppDelegate.m):
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
NSUInteger orientations =UIInterfaceOrientationMaskAllButUpsideDown;
if(self.window.rootViewController)
{
UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presentedViewController supportedInterfaceOrientations];
}
return orientations;
}
in this Stackoverflow post:
iOS 6 AutoRotate In UiNavigationController
New screenshot with navigation controller:
Frustrating. I've tried to make an app Portrait only.
In Targets => Summary => Supported Interface Options, only portrait is selected.
I've put the following on the navigation controller of my app:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
-(BOOL)shouldAutorotate{
return NO;
}
And even copied the same onto the root view controller of the navigation controller. It's still being presented that the view is allowed to be rotated. I'm still able to rotate my app to landscape on the iPad, and possibly even upside down on the iPhone.
Thanks!
