我想实现像Skype这样的屏幕共享功能（当应用程序在后台时，它也会共享iPhone的屏幕），为此我使用广播扩展。

这是我在 viewcontroller.swift 中的代码

    import UIKit
    import ReplayKit
    @available(iOS 12.0, *)
    class ViewController: UIViewController {

        var broadcastPicker: RPSystemBroadcastPickerView?

            broadcastPicker = RPSystemBroadcastPickerView(frame: kPickerFrame)
            broadcastPicker?.backgroundColor = UIColor.green
            broadcastPicker!.preferredExtension = "com.sharescreen.Recoder"
            view.addSubview(broadcastPicker!)

            extensionContext?.loadBroadcastingApplicationInfo(completion: {
            (bundleID, displayName, appIcon) in

            })

        }
   }

当我点击 RPSystemBroadcastPickerView 时，我会弹出开始广播，当我开始广播时，任何扩展方法都没有调用。

这是我的扩展课程

    class SampleHandler: RPBroadcastSampleHandler {


    var session : VTCompressionSession?
    override func broadcastStarted(withSetupInfo setupInfo: [String : NSObject]?) {
        // User …
