In my application, we support both portrait and landscape based the screens. when we push or navigate to portrait mode to landscape mode screen, then some portion of UIView doesn't has user interaction, popover controller view also presented in wrong orientation. This is weird issue ever i had. Please help me to get out of this complicated issue.

I am creating an iOS app that will support iPhone and iPad in landscape and portrait orientations. I have setup my launch screen storyboard with an ImageView and that appears correctly in both landscape and portrait modes in Interface Builder. However, even though I am holding my phone in landscape, the launch screen will always appear in portrait. I have logged my device current orientation in application didFinishLaunchingWithOptions, but it reports UIDeviceOrientation unknown. After the launch screen disappears, the first view appears in landscape as expected.
Do you know why that happens and how to fix it?
Thanks
I think that you haven't open this:
I have 2 root view controllers ViewController1 and TabBarController1(there are reasons for making 2 root view-controllers). ViewController1 only supports Portrait mode and TabBarController1 supports all orientations. ViewController1 appears first after launch. I am locking the orientation of ViewController1 using the following method.
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
The app launch and orientation worked fine with iOS7.
When building the app through Xcode 6 in iPad(iOS8) following change is observed:
- When app is launched in landscape mode, ViewController1 with orientation locked into portrait mode appears with half black screen and when TabBarController1 appears which supports all orientations, doesn't resize with proper dimensions on changing orientations.
I have also tried overriding the above method in TabBarController1 to support all orientation but nothing works fine.
This problem is not observed when launching the app on iPad in portrait mode.
There is no problem when launching the app on iPhone as iPhone launches only in Portrait mode.
What is the issue when working with iOS8 ?
I am a newbie, so don't judge..
In ios8, apple changed 2 things :
1-
[[UIscreen mainscreen] bounds].size
This used to be a fixed value for portrait and landscape, now it is not.
When u change from landscape to portrait the width and height switch.
2-What is happening with you. You cannot force a viewcontroller to be in portrait only if you set portrait and landscape in project settings, do not know why, so you maybe have to set portrait only in project settings for example..
This is happening on iPads and iphone 6+ only.
Hope this helped..
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 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 problem with UIImagePickerController on my iPad. it is presented as a modalView (presentViewController:).
All orientations are allowed and should work.
If I push a ViewController in Portrait mode on this VC (this is the main view of the App), go back to the Springboard, rotate the iPad to Landscape mode, reopen my App, There is a big black space on the screen.
However, the camera controls are well shown.
Has anyone already seen this kind of bug?
Thank you.
This is better with a screenshot
