I am a VoIP app developer currently working on the Picture-in-Picture (PiP) mode. To ensure the video always appears correctly oriented, I need to obtain rotation information when the device rotates. When the app is in the foreground, I can use [UIDevice currentDevice].orientation to retrieve this value and adjust the video accordingly. However, in PiP mode, my app moves to the background, and this API does not function as expected. Similarly, interfaceOrientation of UIWindowScene and [UIApplication sharedApplication].statusBarOrientation do not work in the background. Is there a way to obtain the orientation information of the system status bar when my app enters the background in PiP mode? Thank you in advance.
