Ios 如何不仅录制应用程序'；s屏幕，但屏幕上的所有内容，包括其他应用程序

我正在尝试使用ReplayKit（Swift）实现屏幕录制应用程序。似乎当我走出应用程序时，会停止后台记录。在尝试了一些文档之后，到目前为止，我了解到我需要实现广播扩展。如果我的理解是正确的，那么请给我一些编程指南

试试这个库

或者这个：

否则，您可以：

import ReplayKit
import UIKit

class ViewController: UIViewController, RPPreviewViewControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()

        navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Start", style: .plain, target: self, action: #selector(startRecording))
    }

    @objc func startRecording() {
        let recorder = RPScreenRecorder.shared()

        recorder.startRecording{ [unowned self] (error) in
            if let unwrappedError = error {
                print(unwrappedError.localizedDescription)
            } else {
                self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Stop", style: .plain, target: self, action: #selector(self.stopRecording))
            }
        }
    }

    @objc func stopRecording() {
        let recorder = RPScreenRecorder.shared()

        recorder.stopRecording { [unowned self] (preview, error) in
            self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Start", style: .plain, target: self, action: #selector(self.startRecording))

            if let unwrappedPreview = preview {
                unwrappedPreview.previewControllerDelegate = self
                self.present(unwrappedPreview, animated: true)
            }
        }
    }

    func previewControllerDidFinish(_ previewController: RPPreviewViewController) {
        dismiss(animated: true)
    }
}

Replay Kit仅记录其当前的应用程序屏幕，每当应用程序成为背景时，记录将停止，这是出于设计

以上代码仅记录应用程序屏幕，而不记录整个iPhone屏幕。喜欢这个应用。。请检查这是否可行。我不这么认为。iTunes中已经有一些应用程序具有这一功能。

import ReplayKit
import UIKit

class ViewController: UIViewController, RPPreviewViewControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()

        navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Start", style: .plain, target: self, action: #selector(startRecording))
    }

    @objc func startRecording() {
        let recorder = RPScreenRecorder.shared()

        recorder.startRecording{ [unowned self] (error) in
            if let unwrappedError = error {
                print(unwrappedError.localizedDescription)
            } else {
                self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Stop", style: .plain, target: self, action: #selector(self.stopRecording))
            }
        }
    }

    @objc func stopRecording() {
        let recorder = RPScreenRecorder.shared()

        recorder.stopRecording { [unowned self] (preview, error) in
            self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Start", style: .plain, target: self, action: #selector(self.startRecording))

            if let unwrappedPreview = preview {
                unwrappedPreview.previewControllerDelegate = self
                self.present(unwrappedPreview, animated: true)
            }
        }
    }

    func previewControllerDidFinish(_ previewController: RPPreviewViewController) {
        dismiss(animated: true)
    }
}
