I am currently writing an iOS app in which have the acceptable device orientations set to Landscape Right and Landscape Left, and in all of my view controllers, I’m returning only those two in the supportedInterfaceOrientations method.
However, if the user uses the in-app camera functionality (which is implemented via UIImagePickerController presented modally in full screen) and rotates the device to Portrait orientation to take a picture, the camera rotates to portrait mode (which is fine), and if the user clicks "Use Photo", when the modal view is dismissed, the view from which the camera was launched is somehow now in portrait mode (which is not fine).
After the camera view has been dismissed, the view controller from which it was launched has UIDeviceOrientationIsPortrait set to true. I am wondering how it ended up in this orientation, and how when a picture is taken, I can ensure that the presenting view controller remains in a landscape orientation. Any help is greatly appreciated!

In iOS 6 and later, your app supports the interface orientations defined in your app’s Info.plist file
Have you tried setting it here? Then see if the problem still occurs.
Also, if this doesn't work, try setting the supportedInterfaceOrientations values in the viewWillAppear method of the ViewController that launched UIImagePicker?

I have a portrait and portrait upside-down app. I present an imagePickerController and it allows me to take pictures which can be either landscape or portrait. after taking a picture, the imagePicker verifies if I want to use the photo that was taken. If I hold my device 'sideways' (in a landscape fashion), the image picker view will dismiss like normal and my original view controller will be displayed, except it is in landscape mode (including the keyboard). This should be impossible because my app only supports portrait orientations.
Any ideas on how to keep my app in portrait mode so that the UI doesn't get messed up?
This is my app before I open the imagePicker:
This is the imagePicker right before I dismiss it. although this screenshot is in portrait mode, please imagine that I am holding the device SIDEWAYS (landscape style):
This is the resulting bugged out screen, that I would like to prevent:
I would first check Info.plist and confirm that the orientation is correct and does not contain any landscape options for either iphone or ipad:
I'm working with Xamarin and am having troubles launching my app in the current device orientation.
I have a UINavigationController that I set on my main UIWindow as the root controller. I created a custom UINavigationController which overrides the methods :
GetSupportedInterfaceOrientations
and
ViewWillTransitionToSize
If I hold my iPad in landscape mode and start the app, it will start in portrait mode and then rotate in landscape. I'd like to make it start in the same orientation as the device's physical orientation. From the doc I've read it seems that since iOS 8, everything related to rotations should be handled in the root uiview controller which is my custom UINavigationController.
And here's my problem... let's say I want to start my app in the current device's orientation and then block everything except Portrait once the app is loaded. I tried the 2 following solutions and none worked.
1- I put all interface orientations available in the supported interface orientations key in the info.plist file. I launched the app while holding the iPad in landscape mode. In this case, my app starts in the same orientation as the device which is cool. What is not cool is that it doesn't call my navigation controller method GetSupportedInterfaceOrientations anymore. So even if I change the return value of that method to Portrait only later one, it does absolutely nothing since the method is never called anymore.
2- I removed all supported interface orientations from the info.plist file. I lauched the app while holding the iPad in landscape mode. In this case, my app starts in portrait mode and then rotates to landscape. I want to prevent the rotation and just start the app in the current device's orientation (landscape). With this setup though, I can later change the supported orientation as the navigation controller method GetSupportedInterfaceOrientations is being called everytime we try to rotate the app.
In apple's doc, it says "At launch time, apps should always set up their interface in a portrait orientation. After the application (_:didFinishLaunchingWithOptions:) method returns, the app uses the view controller rotation mechanism described above to rotate the views to the appropriate orientation prior to showing the window."
The part where the view rotates to the appropriate orientation PRIOR to showing the window doesn't seem to work for me. It shows the window and then rotates it after.
So how do you launch an app in the current device's orientation (without the user seeing your first view rotate from portrait to whatever) and then be able to change the supported orientations later in the app? Example : I hold my iPad in landscape mode. I launch my app. First view I see is already in landscape mode. I can then rotate my iPad to change the view in portrait/landscape back and forth. Then I click a button which changes the supported orientation to Portrait which prevents me from changing the orientation to Landscape anymore.
Thanks!
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.
I am almost done developing an app. Right now I'm converting it to a universal app by supporting iPad to supported devices as well.
Can I set the app to use Landscape orientation only, since I am using UISplitViewController and want the Master View Controller to remain on the screen all the time? Is there any Apple policy that states that I cannot restrict it to Landscape only and I have to implement both portrait and landscape? Is there any chance my app can be rejected by setting it to Landscape only for iPad?
Don't worry, you'll be fine. Support both landscape orientations and neither portrait orientation if you want. I've got apps in the store that are like that.
However, note that UISplitViewController does have an option to keep both views on the screen all the time even in portrait. Use the delegate method splitViewController:shouldHideViewController:inOrientation: to forbid hiding the master view:
http://developer.apple.com/library/ios/#documentation/uikit/reference/UISplitViewControllerDelegate_protocol/Reference/Reference.html#//apple_ref/occ/intf/UISplitViewControllerDelegate
So if your only reason for being landscape only is that you don't want to hide the master view, it is a false reason. Look, for example, at Apple's Settings app, which works like that; it is a split view controller that always shows both views in all four orientations.
My project set supported interface orientations to UIInterfaceOrientationMaskPortrait.
When I use presentMoviePlayerViewControllerAnimated: popup an MPMoivePlayerViewController, on IOS5 when I turn device, the controller will do auto orientation rotation, but on IOS6 it is always at portrait direction.
How can I make it act as IOS5?
Apple changed the way orientations are handle in iOS 6:
Controlling What Interface Orientations Are Supported (iOS 6)
When UIKit receives an orientation notification, it uses the
UIApplication object and the root view controller to determine whether
the new orientation is allowed. If both objects agree that the new
orientation is supported, then the user interface is rotated to the
new orientation. Otherwise the device orientation is ignored.
When a view controller is presented over the root view controller, the
system behavior changes in two ways. First, the presented view
controller is used instead of the root view controller when
determining whether an orientation is supported. Second, the presented
view controller can also provide a preferred orientation. If the view
controller is presented full screen, the user interface is presented
in the preferred orientation. The user is expected to see that the
orientation is different from the device orientation and rotate the
device. A preferred orientation is most often used when the content
must be presented in the new orientation.
So if your application is set to allow only portrait mode, you'll never get into landscape mode regardless of what any controller 'sais'.
See Controlling What Interface Orientations Are Supported (iOS 6) for more information.
