iOS 6 shouldAutorotate: is NOT being called
I need an method to knows when user change the orientation...
I have tried
-(BOOL) shouldAutorotate { //never called
UIInterfaceOrientation toInterfaceOrientation = [[UIDevice currentDevice] orientation];
if(toInterfaceOrientation == UIInterfaceOrientationPortrait)
//a code here
return YES;
}
How can I know when the user change the orientation of iPad?
Remember to set the supported orientations in the info.plist.
Try using
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration;
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation;
(Deprecated in iOS 6.0)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation;
Make sure you call this first:
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
Then track orientation change here:
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
//your code here
}
The duration here is important, as that's the amount of time it will take for the orientation change to be complete. It is only at this point that the new orientation will be completely set

ios 6 orientation methods
the orientation methods have changed in iOS 6. my whole app in portrait mode got to many view controllers (not tab bar view controllers) i just want to rotate one of my view controller to landscape mode (it actually displays a webView) when i rotate the device.the below method was working in xcode 4.4 but, it's not in Xcode.4.5
- (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationPortrait ||
interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
interfaceOrientation == UIInterfaceOrientationLandscapeRight );
the above method won't work in xcode 4.5 for this reason i have changed the below method but even though its not working....plz any suggestions thanks.
- (BOOL) shouldAutorotate{
[[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationPortrait];
return self.modalViewController.shouldAutorotate;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
are you implementing supportedInterfaceOrientations as well ? you might want to.
I want to change the orientation of the app without changing the device orientation in iphone app.
I want to change my view from portraid mode to landscap mode programmatically.
And also want to know that will this be accepted by the apple store or not ?
Thanks
Now I got the solution from other that is as follow
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];
when you add this line at that time one warning appear and for remove this warning just add bellow code on you implementation file..
#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 (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
But now want to know is this accepted by apple app store or not ?
thanks
use this line for programmatically change orientation...
[[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..
#interface UIDevice (MyPrivateNameThatAppleWouldNeverUseGoesHere)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
// return NO;
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
i hope this help you..

Add a class variable
Bool isInLandsCapeOrientation;
in viewDidLoad
set this flag to
isInLandsCapeOrientation = false;
Add the following function
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if (!isInLandsCapeOrientation) {
return (UIInterfaceOrientationIsPortrait(interfaceOrientation));
}else {
return (UIInterfaceOrientationIsLandscape(interfaceOrientation));
}
}
To changing orientation from portrait to landscape, let it happens on a button action
- (IBAction)changeOrientationButtonPressed:(UIButton *)sender
{
isInLandsCapeOrientation = true;
UIViewController *viewController = [[UIViewController alloc] init];
[self presentModalViewController:viewController animated:NO];
[self dismissModalViewControllerAnimated:NO];
}
This works fine for me.
To change Orientation portraid mode to landscap mode use this code
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
use this code for programmatically change orientation...
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];
If you want to change the particular view only in landscape..then u can try the following in its viewDidLoad
float angle = M_PI / 2;
CGAffineTransform transform = CGAffineTransformMakeRotation(angle);
[ [self.view] setTransform:transform];
The documentation describes the orientation property as being read-only, so if it works, I'm not sure you can rely on it working in the future (unless Apple does the smart thing and changes this; forcing orientation changes, regardless of how the user is currently holding their device, is such an obvious functional need).
As an alternative, the following code inserted in viewDidLoad will successfully (and somewhat curiously) force orientation (assuming you've already modified you shouldAutorotateToInterfaceOrientation ):
if (UIDeviceOrientationIsPortrait([[UIDevice currentDevice] orientation]))
{
UIWindow *window = [[UIApplication sharedApplication] keyWindow];
UIView *view = [window.subviews objectAtIndex:0];
[view removeFromSuperview];
[window addSubview:view];
}
Clearly, this does it if the user is currently holding their device in portrait orientation (and thus presumably your shouldAutorotateToInterfaceOrientation is set up for landscape only and this routine will shift it to landscape if the user's holding their device in portrait mode). You'd simply swap the UIDeviceOrientationIsPortrait with UIDeviceOrientationIsLandscape if your shouldAutorotateToInterfaceOirentation is set up for portrait only.
For some reason, removing the view from the main window and then re-adding it forces it to query shouldAutorotateToInterfaceOrientation and set the orientation correctly. Given that this isn't an Apple approved approach, maybe one should refrain from using it, but it works for me. Your mileage may vary. But this also refers to other techniques, too. Check

My app has been in the AppStore for a couple of months now and always only worked on iPhone. I recently submitted an update which was rejected because the App does not run on an iPad. The exact reason it was rejected was:
Reasons for Rejection:
2.10: iPhone apps must also run on iPad without modification, at iPhone resolution, and at 2X iPhone 3GS resolution
What do I need to do in Xcode to make my app run on an iPad in the little box with the 2X icon?
Any tips instructions will be massively appreciated...
EDIT
This is my info.plist. This is my first App and I think I did initially chose to set it up with "universal" selected. Is there an easy way back for me to rectify this now?
Start by figuring out why your app doesn't work on the iPad already. Most apps developed for the iPhone will work fine on an iPad (in compatibility mode) with no modification; if yours doesn't, you must be doing something to prevent it. Are you relying on some hardware feature? Making unfounded assumptions about the device you're running on? How does your app fail when run on an iPad?
Once you've figured out why it doesn't work, you'll be much closer than you are now to fixing the problem.
To get your app to run on an iPad in iPhone compatibility mode, you need to build your app for iPhone only.
Remove all the iPad references from the app's plist (nib base, xib and storyboard), and from the Target Build Settings Targeted Device Family.
I had the same issue, I was able to run my app on the ipad after making the following changes.
in the project settings made the Devices to iPhone(it was universal before)
in the .plist removed the main story board file base name related to ipad.
I have solved same issue using this scenario.
You should check for normal and retina images in your resources folder.
You may also get this error while debugging Could not load the "image.png" image referenced from a nib in the bundle with identifier.
A normal iPhone app must run on the iPad in both(1x and 2x) mode without modification. You can check this with the SDK Simulator.
There is a long list in the App Store Review Guidelines on Apple's iOS Developer Portal Center which lists many of the things that Apple reviews this things when you submit an app. Read it carefully.
I'll try to explain what my problem and solution was..
I have an iPhone only app which is mostly in portrait, however, because of 1 or 2 UIViewControllers which have to be in all UIInterfaceOrientations, I have to enable all UIInterfaceOrientations in my plist.
When starting the app on an iPad which is rotated in landscape and is lying on the table (so has UIDeviceOrientationFaceUp), the whole app was shown in landscape, which made my UI totally messed up.
I had no reference to any iPad related code / settings in my plist or launch screens whatsoever (I am using .xcassets for launch screens).
I fixed it by adding 1 line of code to my AppDelegate.m which sets the statusbar orientation to force the app in portrait mode.
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
//Further setup
}
I had the same issue using Cocos2d 2.0
My problem was that the project had evolved over several years and had carried along some now vestigial files like RootViewController and UIViewController and MyRootViewController, etc.
They worked at the time but clearly had raised a flag with today's review committee because I received the "All iPhone apps must work on the iPad" rejection notice. After screaming out loud and finally accepting defeat, I thought that policy makes it pretty hard to make an app iPhone only. Let me know if I am wrong about this.
Even though I was (and am still) perturbed about it, I thought perhaps now I could at least clean up the project with a more elegant solution that handles the base problem: device rotation + content rotation. I ended up using something from a more recent project that was working on and seemed more elegant and actually worked: simply add MyNavigationController to the top of my AppDelegate.
I have added the code below. I am sure it can be improved. Please comment if you can enhance it.
As a result, I was able to delete the old RootViewController and MyRootViewController files so now it's easier to maintain. I never understood their purpose very well anyways. Good riddance!
Here is my solution to displaying and matching device orientation + content orientation:
in AppDelegate.h I had to declare what I was doing:
//top of the file
#interface MyNavigationController : UINavigationController
#end
//inside AppDelegate.h interface
MyNavigationController *navController_;
//bottom of the file before #end
#property (readonly) MyNavigationController *navController;
Here is the code that works at the top of my AppDelegate.m
#implementation MyNavigationController
// The available orientations should be defined in the Info.plist file.
// And in iOS 6+ only, you can override it in the Root View controller in the "supportedInterfaceOrientations" method.
// Only valid for iOS 6+. NOT VALID for iOS 4 / 5.
-(NSUInteger)supportedInterfaceOrientations {
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
if (orientation == UIDeviceOrientationPortrait) {
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
// [director_ pushScene: [IPAD scene]];
} else {
[[CCDirectorIOS sharedDirector] pushScene:[VerticalDisplayLayer scene]];
return UIInterfaceOrientationMaskPortrait;
}
} else if (orientation == UIDeviceOrientationLandscapeLeft) {
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
// [director_ pushScene: [IPAD scene]];
} else {
[[CCDirectorIOS sharedDirector] pushScene:[MainMenuScene scene]];
}
} else if (orientation == UIDeviceOrientationLandscapeRight) {
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
// [director_ pushScene: [IPAD scene]];
} else {
[[CCDirectorIOS sharedDirector] pushScene:[MainMenuScene scene]];
}

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
} else {
[[CCDirectorIOS sharedDirector] pushScene:[VerticalDisplayLayer scene]];
return UIInterfaceOrientationMaskPortraitUpsideDown;

//do nothing

Here is why I had to solve this:
I needed both Landscape and Portrait modes to display different scenes.
Here are some screenshots that describe the situation
I would like to make a custom orientation lock button for a reader app of mine, and I was thinking it wouldn't be too bad to whip up, but alas I am the one getting whipped.
To start off I do have this method:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
And then I was thinking that I could handle the actual locking in an action method like this:
- (IBAction) screenLock:(id)sender{
if([UIDevice currentDevice].orientation == UIDeviceOrientationPortrait){
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait];
}else{
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];
}
}
But alas, this code will not hold sway over the former that instructs the view to rotate...
Am I going about this all wrong? What is a better way to do it? I just want to have local, easy way to have my users lock the orientation of their screen. I guess it would be using a boolean value where they hit a button to lock and then hit again to unlock...
Thoughts?
Thanks!!
shouldAutorotateToInterfaceOrientation ripples up your view hierarchy so your logic needs to be put into your app delegate (or as the most senior ViewController that might return YES). Put a BOOL property in your appDelegate and set it via your lock button (e.g. target pointers/delegates (AppDelegate)) then in your appDelegate do something like this:
#define ROTATION_MASTER_ENABLED 1
//Setting MASTER_ROTATION_LOCK_ENABLED to 0 will stop the device rotating
//Landscape UP>landscape DOWN and Portrait UP>Portrait DOWN,
//This is not generally desired or app store safe, default = 1
-(BOOL)compareOrientation:(UIInterfaceOrientation)interfaceOrientation
{
UIInterfaceOrientation actual = [[UIDevice currentDevice] orientation];
if(UIInterfaceOrientationIsLandscape(interfaceOrientation) && UIInterfaceOrientationIsLandscape(actual))return YES;
else if(UIInterfaceOrientationIsPortrait(interfaceOrientation)&& UIInterfaceOrientationIsPortrait(actual))return YES;
else return NO;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if(!MASTER_ROTATION_LOCK_ENABLED)return NO;
else if(self.rotationEnabled || [self compareOrientation:interfaceOrientation])return YES;
return NO;//self.rotationEnabled is a BOOL
}
Anyone know how to do this?
I thought this:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
}
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration {
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
}
- (void)willAnimateFirstHalfOfRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
}
- (void)didAnimateFirstHalfOfRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
}
- (void)willAnimateSecondHalfOfRotationFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation duration:(NSTimeInterval)duration {
}
may prevent the device from rotation (overriding all rotate methods of my UIViewController and not calling the superclass) but I fear it's not the UIViewController that actually performs the rotation.
My UIViewController is in a UINavigationController.
Anyone have any ideas?
Cheers,
Nick.
You can register for the notification UIDeviceOrientationDidChangeNotification (from UIDevice.h), and then when you care about orientation changes call this method:
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
When you no longer care about orientation changes, call this method:
[[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
The notification will be sent when applicable, and you can check [UIDevice currentDevice].orientation to find out what the current orientation is.
On a side note shouldAutoRotateToInterfaceOrientation used to be called on the time for rotation in 2.x, but in 3.0 it's much less consistent. The notification mentioned in the other post is the way to go for reliable indication of rotation.
You're returning YES from shouldAutorotateToInterfaceOrientation:, which I suspect you didn't mean to do. That's the only method you need to implement to prevent the device from rotating.
As for getting the current orientation of the device, you can use [[UIDevice currentDevice] orientation].
