ios - RPBroadcastSampleHandler 任何未调用的方法

问题描述

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），为此我正在使用广播扩展。

这是我在 viewcontroller.swift 中的代码

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

        var broadcastPicker: RPSystemBroadcastPickerView?
        var broadcastSession : NSObject?
        override func viewDidLoad() {
            super.viewDidLoad()
            let kPickerFrame = CGRect(x: 100.0, y: 100.0, width: 100.0, height: 100.0)
            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。

这是我的扩展类

    class SampleHandler: RPBroadcastSampleHandler {


    var session : VTCompressionSession?
    override func broadcastStarted(withSetupInfo setupInfo: [String : NSObject]?) {
        // User has requested to start the broadcast. Setup info from the UI extension can be supplied but optional.

    }

    override func broadcastPaused() {
        // User has requested to pause the broadcast. Samples will stop being delivered.
    }

    override func broadcastResumed() {
        // User has requested to resume the broadcast. Samples delivery will resume.
    }

    override func broadcastFinished() {
        // User has requested to finish the broadcast.
    }

    override func processSampleBuffer(_ sampleBuffer: CMSampleBuffer, with sampleBufferType: RPSampleBufferType) {
        switch sampleBufferType {
        case RPSampleBufferType.video:
            // Handle video sample buffer

            break
        case RPSampleBufferType.audioApp:
            // Handle audio sample buffer for app audio
            break
        case RPSampleBufferType.audioMic:
            // Handle audio sample buffer for mic audio
            break
        @unknown default:
            // Handle other sample buffer types
            fatalError("Unknown type of sample buffer")
        }
    }
}

你能帮我找出我做错了什么吗？
