First of all, I would like to apologize for asking the same question again which has been asked in this forum many times. But, my problem is that I've tried all the suggested solutions but still I haven't got a solution to my problem.
I have a ViewControllerA in Potrait mode and ViewControllerB in landscape mode. When the device changes from potrait to landscape, i can see ViewControllerB opening in landscape mode, but when the device is rotated back to potrait mode, ViewControllerA is displayed but still in landscape mode. Could anybody help me understand how can I display it back in potrait mode?
I have tried following things but nothing worked for me:
Added following code in ViewControllerA in viewWillAppear:
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];
Have also added following functions in this view controller:
- (BOOL)shouldAutorotate
{
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
Hope this helps you by using supportedInterfaceOrientationsForWindow
Appdelegate.h
#property () BOOL restrictRotation;
in Appdelegate.m
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
//restrictRotation is BOOL value
if(self.restrictRotation)//set the bool value to view controller which you want to load in landscape
return UIInterfaceOrientationMaskLandscape;
else
return UIInterfaceOrientationMaskAll;
}
//call this where you need
requiredViewController.m
-(void) restrictRotation:(BOOL) restriction
{
appDelegate = (AppDelegate*)[UIApplication sharedApplication].delegate;
appDelegate.restrictRotation = restriction;
}
//In ViewdidLoad()
- (void)viewDidLoad
{
[super viewDidLoad];
[self restrictRotation:YES];//Set YES if required in Landscape mode
}
Please try
[[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIInterfaceOrientationPortrait] forKey:#"orientation"];
Use below code
-(void) viewDidAppear:(BOOL)animated
{
[UIViewController attemptRotationToDeviceOrientation];
[super viewDidAppear:animated];
}
& also in viewWIllAppear write
[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIInterfaceOrientationPortrait] forKey:#"orientation"]

I'm just trying to set up my app so that only one view can be viewed in landscape mode.
I've tried just about everything from shouldAutorotate to supportedInterfaceOrientation to preferedInterfaceOrientationForPresentation, and setting [UIDevice currentDevice]'s orientation to portrait. I have Landscape enabled in Info.plist and the project's general section.
Firstly make your application portrait only in your info.plist
Create the following property in your AppDelegate class:
#property BOOL restrictRotation;
Then create the following method in your AppDelegate.m class:
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if(self.restrictRotation)
return UIInterfaceOrientationMaskPortrait;
else
return UIInterfaceOrientationMaskAll;
}
Create the following method in your ViewController and call it right before you want to permit landscape orientation. (Call it with true first in your viewDidLoad method to make sure rotation is restricted)
-(void) restrictRotation:(BOOL) restriction
{
AppDelegate* appDelegate = (AppDelegate*)[UIApplication sharedApplication].delegate;
appDelegate.restrictRotation = restriction;
}
like this:
[self restrictRotation:NO];
and after you are done with your landscape view and its dismissed, call this immediately:
[self restrictRotation:YES];
Hope this answers your question.
also change orientation after locking it:
-(void)forceOrientation:(UIInterfaceOrientation)orientation{
[[UIDevice currentDevice]setValue:[NSNumber numberWithInteger:orientation]forKey:#"orientation"];
}
set in app delegate
For iOS 6 and above to clear the warning in AppDelegate while using Gurtej Singh answer you can replace the AppDelegate code with :
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(nullable UIWindow *)window API_AVAILABLE(ios(6.0)) API_UNAVAILABLE(tvos)
{
if(self.restrictRotation)
return UIInterfaceOrientationMaskPortrait;
else
return UIInterfaceOrientationMaskAll;
}
In your app delegate you could do this:
// Used to show a video in full screen
func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> Int
{
if let presentedViewController = self.window?.rootViewController?.presentedViewController
{
if !presentedViewController.isBeingDismissed() && presentedViewController is MyLandscapeModeViewController // insert your view controller class name here
{
// specify what kind of Orientation you want
return Int(UIInterfaceOrientationMask.AllButUpsideDown.rawValue)
}
}
// show every other View Controller in portrait
return Int(UIInterfaceOrientationMask.Portrait.rawValue)
}
I want to disable the autorotation of iOS device for few view controllers.Like i have one few controller i want it to be displayed only in portrait mode.Where as others view controller in landscape mode.I have used following code but these delegate methods are never called?
#pragma mark Orientation handling
- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
-(BOOL)shouldAutorotate
{
return NO;
}
-(NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskPortrait);
}
I used following method to forcefully set portrait orientation only for some selected view and its work for me, may be it will be help you
1, Create one global flag
Create on Global flag in your AppDelegate Method So you can access it in any View controllers .
In your AppDelegate.h
#property (assign) BOOL flagOrientationAll;
In your AppDelegate.m
#synthesize flagOrientationAll;
Add following method in your AppDelegate.m
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
if(flagOrientationAll == YES){
return UIInterfaceOrientationMaskAll; // All orientation support
} else {
return UIInterfaceOrientationMaskPortrait; // Set only one orientation you want
}
}
2, Add following code in ViewController .m for that you want to restrict rotation
// set flag "flagOrientationAll" to rotate only one view in your particular view
#import AppDelegate.h
-(void)viewWillAppear:(BOOL)animated
{
NSLog (#"webViewController -- viewWillAppear");
[super viewWillAppear:animated];
AppDelegate *delegate = (AppDelegate *) [[UIApplication sharedApplication] delegate];
delegate.flagOrientationAll = YES;
}
-(void)viewWillDisappear:(BOOL)animated
{
AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
delegate.flagOrientationAll = NO;
}
Here my POST : How to set one of the screens in landscape mode in iphone?
If you get any trouble let me know!!
So in cocos2d (I believe I was on v2.1) I did this to lock and set the orientations:
AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
const UIInterfaceOrientation ORIENTATION = delegate.navController.interfaceOrientation;
delegate.navController.
delegate.navController.screenOrientation = ORIENTATION == UIInterfaceOrientationMaskPortrait;
UIViewController *mVC = [[UIViewController alloc] init];
[delegate.navController presentModalViewController:mVC animated:NO];
[delegate.navController dismissModalViewControllerAnimated:NO];
With some functions added to the AppDelegate.
I cannot seem to get the same results in iOS7 and cocos2d v3.
I have dug through a bit and the proper functions seem to be in place but cannot seem to set up a global variable to set the orientation and return only the one I want at the certain time. Can someone point me down the proper path. I think I'm missing something really small cause the proper code seems to be there already.
Here's the code for my AppDelegate
#implementation AppDelegate
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self setupCocos2dWithOptions:#{
CCSetupShowDebugStats: #(NO),
}];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
return YES;
}
-(CCScene *)startScene
{
return [HomeScreen scene];
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
My code never hits the interfaceOrientation functions.
Thoughts??!?
After a couple days fooling around I figured out a solution:
in AppDelegate I needed this function:
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if (!self.lockedToOrientation) {
if( [[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone ){
return UIInterfaceOrientationMaskPortrait;
}
return UIInterfaceOrientationMaskPortrait;
}
else {
return self.lockedToOrientation;
}
}
Where
#property UIInterfaceOrientationMask lockedToOrientation;
Hope this helps someone!
Cheers.
I have an app that is always showed in portrait mode.
But in somewhere i have a media gallery that must support landscape.
The supported orientation by default in the project is portrait. Because of that the gallery is only showed in portrait mode.
If i change the project setting to show in portrait and landscape the gallery works fine but i can't control the other viewControllers to show only in portrait.
I tried several methods like shouldAutoRotate but no one worked.
Any ideia how to solve?
Regards
EDIT:
Solved :)
First i configured the project to support all orientation.
Then i added this method to the AppDelegate.m:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscape;
}
After this what i did was to block orientation in each view controller, less the one i want to have orientation in landscape and portrait.
Code to block orientation (iOS 7):
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskPortrait);
}
Thanks to everyone that answered me :)
In my app for iPhone its only support the portrait view only, but as per requirement need to support landscape view only for on view, at that time I use following way and its help me :
In your app delegate .h
#interface PlayWithWSWithLibAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {
BOOL flagOrientationAll;
}
#property (assign) BOOL flagOrientationAll;
Add following method in your app delegate .m file
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
//NSLog(#"PlayWithWSWithLibAppDelegate -- supportedInterfaceOrientationsForWindow");
if([UICommonUtils isiPad]){
return UIInterfaceOrientationMaskAll;
}else if(flagOrientationAll == YES){
return UIInterfaceOrientationMaskAll;
} else {
return UIInterfaceOrientationMaskPortrait;
}
}
Implement following way in your view which you want to rotate in both portrait and landscape both for iPhone device
-(void)viewWillAppear:(BOOL)animated
{
self.tabBarController.delegate = self;
PlayWithWSWithLibAppDelegate *delegate = (PlayWithWSWithLibAppDelegate *) [[UIApplication sharedApplication] delegate];
delegate.flagOrientationAll = YES;
}
}
-(void)viewWillDisappear:(BOOL)animated
{
//NSLog(#"viewWillDisappear -- Start");
PlayWithWSWithLibAppDelegate *delegate = (PlayWithWSWithLibAppDelegate *)[[UIApplication sharedApplication] delegate];
delegate.flagOrientationAll = NO;
}
see this post also: How to set one of the screens in landscape mode in iphone?
You have to make another class in the same view Controller where you are presenting your media.
In that you can specify your orientation where it will support only landscape orientation only when you will present your media.
I am giving you an example of my app which supports only in landscape mode but as I took Image picker and it supports only in portrait mode so I changed the orientation for only that view.
#pragma mark - Image PICKER
#interface NonRotatingUIImagePickerController : UIImagePickerController
#end
#implementation NonRotatingUIImagePickerController
- (BOOL)shouldAutorotate
{
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait ;
}
#end
Then when I used ImagePicker I used object of the class that i made.
So I define like below.
UIImagePickerController* picker = [[NonRotatingUIImagePickerController alloc] init];
So For Image Picker It showed only in portrait mode.
You just need to change Landscape instead of portrait if you want only Landscape Orientation for your particular view where you want to change it.
Hope this helps you.
Please don't suggest me it is a bad idea to have the rotation at ios 4.3-6.0 in 1 build, because I told to many times and didn't listen to me.
At project settings I have setted all interface orientations to be supported, just to be sure.
Right now I am testing on ios6 with iphone4. Starting at app delegate it is a code, like this:
mainController = [[MainViewController alloc] initWithNibName:nil bundle:nil];
navigationController=[[RotatingNavigationController alloc] initWithRootViewController:mainController];
navigationController.navigationBar.hidden =true;
// ios: 4 and 5
//[window addSubview:navigationController.view];
//ios6:
window.rootViewController = navigationController;
[window makeKeyAndVisible];
So I did 2 custom classes, which are recommended in may cases for autorotations, and for they the problem is solved.
The RotatingNavigationController is a custom UINavigationController has a bit ugly code, but I have collected this parts from this forum, so it should be allowed to post it:
#implementation RotatingNavigationController
- (id)init {
self = [super init];
if (self) {
self.view.autoresizesSubviews = YES;
[self.view setAutoresizingMask:(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth)];
}
return self;
}
// ios6 require this method for rotation detection, available from ios5, ios4.3 not available: sux
//- (void)viewWillLayoutSubviews
//{
//UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation;
//[[NSNotificationCenter defaultCenter] postNotificationName:UIDeviceOrientationDidChangeNotification object:nil];
// [[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil];
/*
if(UIInterfaceOrientationIsLandscape(statusBarOrientation)){
[self willRotateToInterfaceOrientation: statusBarOrientation duration: 0.3 ];
}
else{
[self willRotateToInterfaceOrientation: statusBarOrientation duration: 0.3 ];
}
*/
//}
//ios 4.3 and ios 5.0, at ios6 it isn't called by iOS...sux
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
[self.visibleViewController willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
}
// //ios 4.3 and ios 5.0, at ios6 need different methods, which sux
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
//Autorotation is changing in iOS 6. In iOS 6, the shouldAutorotateToInterfaceOrientation: method of UIViewController is deprecated. In its place, you should use the supportedInterfaceOrientationsForWindow: and shouldAutorotate methods.
// ios6
- (NSUInteger)supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskAll;
}
// ios6
- (BOOL)shouldAutorotate
{
return YES;
}
// ios6
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationMaskPortrait;
}
#end
this should generate the autorotation notifications properly, I think he it does his job.
The MainViewController is a custom UIViewController.
just to be sure I have copy-pasted the code:
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
// return (interfaceOrientation == UIInterfaceOrientationPortrait);
return YES;
}
// ios6:
- (NSUInteger)supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskAll;
}
// ios6
- (BOOL)shouldAutorotate
{
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationMaskPortrait;
}
His job is to change the different UIViewController based on device state ( rotations )
I have somewhere a Menu screen, which has different xib, but h and m file too ( because has different elements, which doesn't appear in Portait or Landscape. ( I don't have the power to change the whole architecture )
A part of the code - and here should be some problem, I think is below in this Maincontroller:
#pragma mark
#pragma mark Rotation
- (void)orientationChanged:(NSNotification *)notification
{
UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation;
if(deviceOrientation == UIDeviceOrientationFaceUp || deviceOrientation == UIDeviceOrientationFaceDown){
if(debug){
NSLog(#"Nothing to change because it is gone to Flat");
}
return;
}
NSArray *viewControllers = [self.navigationController viewControllers];
if (UIDeviceOrientationIsLandscape(deviceOrientation)){
//if(debug)
// NSLog(#"Portait -> Landscape size : %3.0fw, %3.0fh", self.view.bounds.size.width, self.view.bounds.size.height);
id lastviewController = viewControllers.lastObject;
// check what is there:
if([lastviewController isKindOfClass:[MenuController class]]){
[self.navigationController popViewControllerAnimated:NO];
[self.navigationController pushViewController:menuLandscape animated:NO];
NSLog(#"poped Menu Portrait, pushed Menu Landscape");
}
...
else if(UIDeviceOrientationIsPortrait(deviceOrientation)){
//else if(UIInterfaceOrientationIsLandscape(statusBarOrientation)){
//if(debug)
// NSLog(#"Landscape -> Portait , size : %3.0fw, %3.0fh", self.view.bounds.size.width, self.view.bounds.size.height);
id lastviewController = viewControllers.lastObject;
// check what is there:
if([lastviewController isKindOfClass:[MenuLandscapeController class]]){
[self.navigationController popViewControllerAnimated:NO];
[self.navigationController pushViewController:menuPortait animated:NO];
}
...
The problem is: the landscape is taken out and is pushed the portait, when is upside down, but that portait aren't rotating and it shows a broken layout.
How can I wake up that controller and tell him is time to rotate, because it isn't in portrait mode?
Thanks any suggestion related to my question of any improvement beside of architecture change.
Update:
at app delgate doesn't helped adding the:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
return UIInterfaceOrientationMaskAll;
}
code from other answer: presented here
Update2:
UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation;
doesn't want to take the UIInterfaceOrientationPortraitUpsideDown = UIDeviceOrientationPortraitUpsideDown value for some reason, I think that need to be solved.
Update3:
Read very carefully twice and third the ios6 release notes
The system determines whether an orientation is supported by
intersecting the value returned by the app’s
supportedInterfaceOrientationsForWindow: method with the value
returned by the supportedInterfaceOrientations method of the top-most
full-screen controller.
now read again :)
Add this category to viewcontroller which doesn't rotate
#implementation UINavigationController(Rotation)
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAll;
}
#end
