I am making game which supports only landscape orientation but I am also using a library to share my game video but that share screen require portrait orientation , If I don't enable portrait orientation my game got crash but If I enable portrait orientation to avoid this crash then my whole game become useless by becoming portrait as it is only for landscape.
This is my game Landscape View as shown by figures below,
This is the Library Portrait View to Share video
My Game View after sharing video from library
Please help me How can I enable portrait orientation for this library to avoid crash
and my rest of the app always remain in landscape and it never goes to portrait orientation.
Thanks
Add the following method to your application's AppDelegate.m file:
// IOS 6
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
return UIInterfaceOrientationMaskAll;
}
In both cases you must also make sure that you have added the landscape only orientation handling code to your game's main UIViewController.
// IOS 5
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}
// IOS 6
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}
Try to implement orientation methods to your view controller.

I hope this help you.
In the view controller you want to support orientation override supportedInterfaceOrientations method.
I did like this...
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationLandscapeLeft | UIInterfaceOrientationLandscapeRight;
}

For the app, the orientation is in portrait most of the time, but we have one view that needs to be set to landscape. I have this code to set it to landscape:
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
I also have device orientation set to portrait and landscape left in the general tab for the app.
The issue is that the app will sometimes work properly but other times it will get stuck in a mix between portrait and landscape.
I have provided an image of what it looks like getting Stuck in transition. If I then reload the view it will work properly, it is only on the first time opening the view that it has a chance of failing.
I think you should set this in AppDelegate.m
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(nullable UIWindow *)window {
if self.rotatble {
return UIInterfaceOrientationMaskLandscape
} else {
return UIInterfaceOrientationMaskPortrait
}
Might this is duplicated one, but I am not getting exactly what I want.
My application is only Portrait base and in which I want to show a Video file in MPMoviePlayerViewController only and only in Landscape mode. but unable to do that.
I've set my device orientation only Portrait and in which I wanna show movie direct in landscape mode. If any one did it then share it with me....thanks in advance
Is it possible once I defined my app is only in Portrait mode(through PLIST/ Development Info setting) and then I want to change Orientation from programing(ex. Landscape mode).???
In the project file, make sure you are supporting the Landscape Orientations
Now in all of your ViewControllers that should still be Portrait Only, add this code
- (BOOL)shouldAutorotate {
return NO;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
When your MPMoviePlayerController view becomes fullscreen, it will be a new ViewController layered on top of everything else. So, it will be allowed to rotate according to the Supported Interface Orientations of the Project. It will not see where you forced the other ViewControllers into Portrait.
I am trying to disable screen rotation in cocos2d-3.x, but I cannot figure out how. I have the following code in CCAppDelegate:
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
setupCocos2dWithOptions:
[self setupCocos2dWithOptions:#{
CCSetupShowDebugStats: #(YES),
// Run in portrait mode.
CCSetupScreenOrientation: CCScreenOrientationPortrait,
}];
return YES;
}
The screen is in portrait mode, but it also rotates to portrait UpsideDown. I read that Cocos2d uses a UIViewController so should I use an apple method for this?
Cocos2D currently only allows to choose between "Landscape" or "Portrait" but doesn't allow to specify the orientation more specific. This likely will be fixed in Cocos2D but for now you can modify the Cocos2D source code as a workaround. I have opened a GitHub Issue for this problem.
Implementing supportedInterfaceOrientations in CCAppDelegate does not fix the issue because the method is implemented by the CCNavigationController and that overrides your settings.
Open "CCAppDelegate.m" and go to line 77. You should see this method:
-(NSUInteger)supportedInterfaceOrientations
{
if ([_screenOrientation isEqual:CCScreenOrientationAll])
{
return UIInterfaceOrientationMaskAll;
}
else if ([_screenOrientation isEqual:CCScreenOrientationPortrait])
{
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}
else
{
return UIInterfaceOrientationMaskLandscape;
}
}
You can change the entire method to only support one orientation, e.g.:
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationPortrait;
}
When you change that method you can return one of the 4 orientations you want to lock your game into:
UIInterfaceOrientationMaskLandscapeLeft
UIInterfaceOrientationMaskLandscapeRight
UIInterfaceOrientationMaskPortrait
UIInterfaceOrientationMaskPortraitUpsideDown
That's the workaround for now.
I have an app that uses the proximity sensor but the proximity sensor does not work in landscape mode. I have heard that if you keep the status bar in portrait mode it the sensor will work
I have tried this but it did not work.
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
The status bar still switched into landscape mode.
What do I do?
If you would like to keep your app in portrait mode regardless of DeviceOrientation, I would suggest you add the following code to your viewController.
- (BOOL) shouldAutorotate{
return NO;
}
- (NSUInteger) supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationPortrait;
}
This will ensure that your app will start in portrait mode, and stay in portrait mode, even if the device is turned.
EDIT: In order to keep the app in landscape while having just one view on portrait mode, add the above code to the one viewController you would like to restrict to portrait mode.
Add the following function to your appDelegate:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
/* This is in order to allow views that do not support landscape mode to be able to load in
*/
return UIInterfaceOrientationMaskAll;
}
Add the following code to your other view controllers:
- (BOOL) shouldAutorotate{
return YES;
}
- (NSUInteger) supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscape;
}
- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationLandscapeRight; //you can choose either landscape orientation here
}
I suggest you use this hierarchy:
RootViewController - it will contain the reference (preferably
strong) to your proximity sensor, which I recommend you run on a
background thread. This will support only portrait mode, so your
proximity sensor will work ok (I hope).
displayViewController - it will contain all the UI elements you have, and support only landscape mode
You could manage communication between both of them by using delegates
Also, after the viewDidApper of RootViewController, please use the presentViewController (iOS 6.0 and above) or presentModalViewController (iOS 5.x) selector to add the displayViewController's view on screen. Using [self.view addSubview: displayViewController.view]; will not work (I speak from personal experience).
My app is a universal application that supports portrait and portrait upside down orientations.
My app uses a UITabBarController that has UINavigationControllers for 3 UITabBarItems.
To support of of these, i have done the following things:
1) added "supported Interface Orientations" key accordingly for both devices
2) added the following code in app delegate and all other view controllers
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown);
}
Everything is going as expected in iPad, but on iPhone, only some of my views (not all) do not respond to change in Orientation..!! Why is this happening??
You should check that all of your view controllers have the rotation defined, and then you should add this to them:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return YES;
}
If you're using a navigation controller, you should create a subclass .i.e. "MyNavController" with the instructions to rotate in its implementation:
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown);
}
and then use it:
MyNavController *navo = [[MyNavController alloc] initWithRootViewController:myRootController];
As far as I know upside down in portrait mode for the IPhone is not allowed, cause when a user receives a phonecall, the app is on hold and he has the phone upside down. Thats why apple does not want that.
