介紹

• iOS 中使用RPScreenRecorder進(jìn)行專門(mén)的錄屏操作。
• 開(kāi)始錄屏?xí)r會(huì)彈出授權(quán)對(duì)話框，錄制過(guò)程中是無(wú)感的，停止錄制之后可以彈出錄制的預(yù)覽界面，然后可以保存到相冊(cè)。
• 錄屏的同時(shí)可以錄制麥克風(fēng)的聲音與攝像頭的內(nèi)容。
• 需要導(dǎo)入ReplayKit模塊。

案例

import ReplayKit
import UIKit

class ViewController: UIViewController {
    // 顯示攝像頭
    var cameraView: UIView?

    override func viewDidLoad() {
        super.viewDidLoad()

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

    @objc func startRecording() {
        guard RPScreenRecorder.shared().isAvailable else { return }
        // 獲取RPScreenRecorder
        let recorder = RPScreenRecorder.shared()
        // 開(kāi)啟麥克風(fēng)
        recorder.isMicrophoneEnabled = true
        // 開(kāi)啟攝像頭
        recorder.isCameraEnabled = true
        // 攝像頭類型（前、后攝像頭）
        recorder.cameraPosition = .front
        // 開(kāi)始錄制
        recorder.startRecording { [unowned self] error in
            if let error = error {
                print(error.localizedDescription)
            } else {
                self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "停止錄屏",
                                                                         style: .plain,
                                                                         target: self,
                                                                         action: #selector(self.stopRecording))
                // 設(shè)置攝像頭
                guard let cameraView = recorder.cameraPreviewView else { return }
                cameraView.frame = CGRect(x: 0, y: 0, width: 300, height: 300)
                cameraView.center = view.center
                view.addSubview(cameraView)
                self.cameraView = cameraView
            }
        }
    }

    @objc func stopRecording() {
        let recorder = RPScreenRecorder.shared()
        // 停止錄制
        recorder.stopRecording { [unowned self] preview, _ in
            self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "開(kāi)始錄屏",
                                                                     style: .plain,
                                                                     target: self,
                                                                     action: #selector(self.startRecording))
            if let preview = preview {
                // 設(shè)置代理
                preview.previewControllerDelegate = self
                self.present(preview, animated: true)
            }
        }
        cameraView?.removeFromSuperview()
    }
}

extension ViewController: RPPreviewViewControllerDelegate {
    // MARK: 完成預(yù)覽
    func previewControllerDidFinish(_ previewController: RPPreviewViewController) {
        dismiss(animated: true)
    }
}

注意：需要在真機(jī)運(yùn)行測(cè)試。
