My app’s device orientation is set to portrait, however when rotating the device into landscape mode, the app is keeping its portait mode but the keyboard is rotating into landscape mode...Something that is unexpected.
Why is that happening and how to prevent it?
Thanks

After not getting any answer and making more researches, I came across this Answer:

Because I just needed the portrait orientation in my app the following worked for me :
[[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
I put that in my main Navigation Controller's viewDidLoad.
I know it's late. But maybe it will help someone else. I had the similar issue. My app should support portrait orientation for iPhone and all orientations for iPad. So, on the iPhone scene didn't rotate, but keyboard did. All my UI was made from code, I also init view controllers (including root) through code. But I didn't remove default Main.storyboard file. When I removed string in Target -> General -> Main Interface, it help me. It was not obvious.

So I know objective-c is no longer being updated and is kind of left behind now but I'm still learning on how to code so it is perfect.
I have an app that I am creating with menues in portrait and the main game is in landscape. I have made the ViewControllers into landscape and when turning the device into landscape it works perfectly but when the device is kept in portrait the game is all messed up.
Could anyone help me with how to force rotate/make the game wait until the screen is portrait? The game looks really messed up portrait so I would prefer if the screen was forced to rotate.
Thanks
In the view controllers that need their orientation updated, add:
[UIViewController attemptRotationToDeviceOrientation];
in their viewDidLoad.
Technical Note TN2244: Launching your iPhone Application in Landscape states:
The values of the UISupportedInterfaceOrientations key determine how the status bar is positioned while the the app is launching. In iOS 7 and below, if the UIInterfaceOrientationPortrait value is present, the status bar will always be positioned for portrait orientation. Otherwise, the status bar will be positioned according to the first orientation that appears under the UISupportedInterfaceOrientations key.
So in iOS 8 it was perfectly fine to put UIInterfaceOrientationLandscape first in the UISupportedInterfaceOrientations list to have your app to start in Landscape.
It does not work anymore in iOS 9. Having UIInterfaceOrientationPortrait in the list at any position forces app to start in Portrait.
Question
Is there a known workaround for this? I need my app to start in Landscape.
Note: Using viewControllers' supportedInterfaceOrientations() method is not an option as it takes effect after the LaunchScreen is presented.
Having UIInterfaceOrientationPortrait in the list at any position forces app to start in Portrait.
That is absolutely correct — very good detective work. It took me a lot of experimentation to figure this out! This is certainly a huge change from iOS 8. You have summed up the situation very well.
Fortunately, the workaround is simple. In your Info.plist, include only the two landscape orientations. Now the app will launch into whichever one is first.
Now implement application:supportedInterfaceOrientationsForWindow: in the app delegate to return All. That way, when the time comes to show a portrait view controller, it will be legal to do so.
In other words, think of the Info.plist as what the launching app needs to know, and application:supportedInterfaceOrientationsForWindow: as what the running app needs to know.
I have a problem in iOS. It's support all interface orientations. But when orientation-locked modal controller is presented (by calling [self presentViewController:UIViewController animated:YES completion:nil]), sometimes the UI orientation is messed up.
Here are the steps:
Orientate the device so it's in portrait mode (doesn't matter portrait or upsideDown).
Present view controller as modal controller. This controller only support landscape mode. The UI orientation obviously rotated to landscape. Keep the device in portrait (since the controller is forced to landscape, the UI will still show a landscape UI eventhough the device is in portrait).
Dismiss the modal controller. Now the main UI is in landscape mode. The problem is, this main UI is supporting all orientations (like stated above).
After doing some interaction (without changing the device orientation), the device orientation suddenly back to portrait, but the UI does not follow suit.
Here's how the final screenshot:
My current thought is that this is iOS bug. I want to look for another opinions regarding this bug. I've search around the net (bing and google) and found nothing.
I often saw this in apps, sometimes even in iOS itself (on homescreen etc)..
I think it's an iOS bug and we as developers can nothing do about it, just write bug reports.
My app is entirely designed for IOS6. I use an xib for the iPhone and another one for the iPad. My AppDelegate sets up a TabBarController, though there is no class for the TabBarController itself. The TabBarController has two tab items, 1 a NavigationController, and 1 a View Controller, each of which has its own class. I would like the iPad to be able to run in just Portrait mode, upside down, and normal. On the summary tab of Target in Xcode, I have supported interface orientations set to Portrait and Portrait Upside Down.
My understanding with iOS 6 is that you only need to put
- (NSUInteger)supportedInterfaceOrientations
in the highest parent controller of a class, and set which Masks you would like it and all the child containers to work with. So, in the Root View Controller of the Navigation Controller I put:
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait|UIInterfaceOrientationMaskPortraitUpsideDown;
}
And in each of the child classes, I put:
- (BOOL)shouldAutorotate{
if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad )
{
return YES;
}
else
{
return NO;
}
}
I then put the same two methods in the 2nd Tab which was just a View Controller Class.
I installed the app on my iPad, and it worked fine in portrait mode, but did not rotate when I turned it upside down. I exited the app and turned the iPad upside down, but when I started the app again, it still stayed in the same spot. So, I killed the app completely, and started it from the beginning upside down. The splash screen was upside down, but when the screen disappeared, the app was still only showing in portrait mode, making the display upside down.
What am I missing?
click on appName select Target and just select the orientations which you want to support. thanks
The code above is great for pre iOS 6. For iOS 6 you have to use the mask orientation. If you want all of the views in iPad to rotate or just some you have the choice of using the above answer. If you want to hard code it the check my answer in the following link for a detailed code for autorotation of all masks or just rotate one view and let the others don't rotate. Any how here is the link
iOS 6 supportedInterfaceOrientations issue
The above answer is providing you with the right solution as well but if you want to learn how to code it check my answer in the link above. Happy coding.
Is the Rotation Lock enabled or not ? (If you are new to iOS, double tap the home button, and slide to the right: it's the little metal-styled button in shape of an arrow).
If you want to run your application to run on portrait mode only than,
1. Select Your Target.
2. In General -> Development Info -> Device Orientation Uncheck all other orientation.Portrait mode only should be checked.Than run your project.
I searched for other existing posts, but none of them satisfied my requirements.
Here is the problem i face,
My app supports both the Modes , landscape and portrait.
But my first screen only supports Landscape , so the app must start in Landscape.
I have set supported Orientation to all the 4 options
I have set the Initial interface orientation to Landscape (left home button)
In the view controller of the first screen i am defining the below
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortrait);
}
And when i start the app the simulator always opens in Portrait and my view is all messed up in the portrait mode , since it is designed only for the landscape.
After the switch to the Landscape, the device remains in this mode.
can anyone help me with the solution to avoid this ?
Thanks

EDITED :
This info may be helpful , The problem is faced only when i hold the device in Portrait and then launch the app.
Its not the duplication of this question, Landscape Mode ONLY for iPhone or iPad
Landscape Mode ONLY for iPhone or iPad
I do not want my app to be only in Landscape , i want only the first screen of my app to be only in Landscape.
I did some experimenting with an app I'm working on that has the same requirements, and came up with the following:
To set the initial orientations that are supported when the app is first launched, use the "Supported Device Orientations" setting for your target.
Also back that up with the appropriate shouldAutorotateToInterfaceOrientation code, as you've already done.
For subsequent screens, simply use the shouldAutorotateToInterfaceOrientation code to determine which orientations you want to support. Even if you've specified only landscape modes for the Supported Device Orientation, shouldAutorotateToInterfaceOrientation wins. :)
I think this approach is a little cleaner than using an extra dummy VC.
I achieved a workaround for the Problem and it solved ,
I created a dummy view controller and added as the root view controller of the Window.
Added the below method in the implementation
-(void)viewDidAppear:(BOOL)animated
{
WelcomeScreen *welcomeScreen = [[[WelcomeScreen alloc] initWithNibName:#"WelcomeScreen" bundle:nil] autorelease];
[self presentModalViewController:welcomeScreen animated:NO];
}
Now it worked as expected.
Here is a SO link that will hopefully answer your question on how to launch your app in landscape mode.
