- (BOOL)shouldAutorotate
{
return NO;
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
@endBut in eclipse java project I dont know how to bridge it. Can you help me please? Thanks

UIViewController controller =((IOSApplication) Gdx.app).getUIViewController();
But if I create MyUIViewController with:
public class MyUIViewController extends UIViewController{
@Override
public boolean shouldAutorotate() {
return true;
}
@Override
public UIInterfaceOrientationMask getSupportedInterfaceOrientations(){
return UIInterfaceOrientationMask.Landscape;
}
And put:
MyUIViewController myvc =(MyUIViewController) ((IOSApplication) Gdx.app).getUIViewController();
It crashes complaining about an impossible casting:
Exception in thread "main" java.lang.ClassCastException: com.badlogic.gdx.backends.iosrobovm.IOSGraphics$IOSUIViewController cannot be cast to com.myApp.demo.MyUIViewController
Any idea? Many many thanks in advanced!
Best regards,
Luis.

Root VC - Supported orientations: UIInterfaceOrientationMask(0x1a = AllButUpsideDown(0x1a))
Root VC - Should Autorotate: true
MyImagePicker - Supported orientations: UIInterfaceOrientationMask(0x1e = All(0x1e))
MyImagePicker - Should Autorotate: false
So, I believe that MyImagePicker is performing as required and the problem comes from RootViewController.
How to override ShouldAutorotate or getSupportedInterfaceOrientations() of my RootViewController?
Why if it is returning 0x1a = AllButUpsideDown(0x1a), it fails even when landscape it is supposed to be in 0x1a?
My app is landscape only and it issue avoids me finishing the App. Please, could yo help me?
Any advice Niklas?

Just two days ago, I had a similar issue in that my application normally runs the libgdx view controller in landscape mode, but there are some iOS specific view controllers (VC) that are presented and run in portrait mode. The problem I was having was that whilst each presented VC could correctly return "true" for shouldAutorotate() and could return the correct mask from getSupportedInterfaceOrientations(), when returning to the libgdx VC from a portrait presented VC, the orientation would not return to landscape, as set by the libgdx IOSApplicationConfiguration settings.
My solution was to make several changes:
First, I ensured that the info.plist contained LandscapeLeft, LandscpaeRight, and Portrait orientations, with LandscpeLeft listed first to ensure that the application launches in that orietnation.
Second, I made sure each of my presented VCs contained the following code to allow all orientations, but prefer Portrait:
@Override
public UIInterfaceOrientationMask getSupportedInterfaceOrientations() {
return UIInterfaceOrientationMask.All;
}
@Override
public UIInterfaceOrientation getPreferredInterfaceOrientation() {
return UIInterfaceOrientation.Portrait;
}
public boolean shouldAutorotate() {
return true;
}
@Override
return true;
}
Third, I modified the libgdx file backends/gdx-backend-robovm/src/com/badlogic/gdx/backends/iosrobovm/IOSGraphics.java to override getSupportedInterfaceOrientations() to return a mask derived from the libgdx IOSApplicationConfiguration settings. This change has now been pulled into the libgdx repo on GitHub and is available in the nightly builds. See https://github.com/libgdx/libgdx/commit/68ce111b5136b29f4c4977d7e2c3ae09e1ff2a83 for details.
Hope that helps.
