How to change screen orientation at runtime on ios?

[mikydown]

I’m developing a mobile app where the default orientation is portrait. I want to trigger landscape orientation on a specific screen and return to portrait when exiting that screen. On Android, I can use SetAllowedDeviceOrientation to dynamically switch the screen orientation. However, it doesn’t seem to work on iOS. I tried enabling SupportsLandscapeLeftOrientation , but the screen rotates automatically following the device orientation, which is undesirable. Is this a bug in UE5.1? I haven’t tried other versions, and this has left me feeling confused.

Hi! Did you find solution?

Sorry, I have already resolved this issue. You might need to add some Objective-C code yourself. After calling SetAllowedDeviceOrientation, call ForceRefreshIOSOrientation. For example:

void UCustomizeIOSFunctionLibrary::ForceRefreshIOSOrientation()
{
#if PLATFORM_IOS
    dispatch_async(dispatch_get_main_queue(), ^{
    
        if (@available(iOS 16.0, *)) {
            [[IOSAppDelegate GetDelegate].IOSController setNeedsUpdateOfSupportedInterfaceOrientations];
        } else {
            [UIViewController attemptRotationToDeviceOrientation];
        }
    });
#endif
}

This might not be the best method, but it works for me.
