Function Introduction "https://developer.apple.com/documentation/avkit/creating-a-multiview-video-playback-experience-in-visionos/"

When I use this function, my videoPlayer has no back Action in player. And we did not find any method provided by the system "addChildViewControllerAndView(form)"

"https://developer.apple.com/documentation/avkit/adopting-the-system-player-interface-in-visionos" Referencing this document also did not work

As long as you enter this line of code

let playerController = AVPlayerViewController()
// Enable the multiview experience along with the default recommended set.
playerController.experienceController.allowedExperiences = .recommended(including: [.multiview])

there is no back button, only full screen and zoom out

Hey @Liangmu,

The addChildViewControllerAndView function is not a system provided function but rather a convenience function that encapsulates the steps required to add a child view controller. To learn more on the steps required to do this see Creating a custom container view controller.

Could you provide more information on when you are expecting a back button? There is no such button when the video player is playing in the embedded state. When the video is playing in full screen mode there is a button that closes the video player which returns you to the embedded state and/or your content. Do you not have such a button?

Let me know if that helps. Michael

Hi Michael, Could you try adding this code in the "DestinationVideo" demo:

controller.experienceController.allowedExperiences = .recommended(excluding: [.multiview])

I couldn’t find the addChildViewControllerAndView method. However, my implementation matches the example from the link you provided. I originally thought this method might include options for setting the video to full screen, but it seems it’s only for handling UI.

Also, I found an issue in the “DestinationVideo” demo with versions before visionOS 2.1. In the video playback page, when opening the playlist and selecting a video to play, the playlist doesn’t close automatically, which makes it impossible to interact. I tried using dismiss() in selectionAction, but it didn’t work either. It works fine in visionOS 2.1.
