应用程序未在RPBroadcastActivityViewController中显示为广播服务

if #available(iOS 10.0, *) {
  RPBroadcastActivityViewController.load { broadcastAVC, error in
    guard error == nil else {
      print("Cannot load Broadcast Activity View Controller.")
      return
    }
    if let broadcastAVC = broadcastAVC {
      broadcastAVC.delegate = self
      self.viewController.present(broadcastAVC, animated: true, completion: {
        // broadcastactivityviewcontroller will perform the callback when the broadcast starts (or fails)
      })
    }
  }
}

here ,代码在 startBroadcast 作用

我还尝试使用 withPreferredExtension preferred broadcast service not found . 当我去控制中心尝试启动广播会话时,我发现没有 Start Broadcast 按钮,没有应用程序,只是 Start Recording ,我用的是IOS11,所以我试着用一部手机用IOS12,关于控制中心的结果也是一样的。
