swift 屏幕录制

步骤 1：导入 ReplayKit

import ReplayKit

步骤 2：开始录屏

let screenRecorder = RPScreenRecorder.shared()
// 麦克风或系统音频
screenRecorder.isMicrophoneEnabled = true

func startRecording() {
    guard screenRecorder.isAvailable else {
        print("Screen recording is not available on this device.")
        return
    }

    screenRecorder.startRecording { error in
        if let error = error {
            print("Error starting recording: \(error.localizedDescription)")
        } else {
            print("Recording started successfully.")
        }
    }
}

步骤 3：停止录屏

func stopRecording() {
    screenRecorder.stopRecording { previewController, error in
        if let error = error {
            print("Error stopping recording: \(error.localizedDescription)")
        } else {
            print("Recording stopped successfully.")
        }

        // 可选择展示预览界面
        if let previewController = previewController {
            previewController.previewControllerDelegate = self
            self.present(previewController, animated: true)
        }
    }
}
extension YourViewController: RPPreviewViewControllerDelegate {
    func previewControllerDidFinish(_ previewController: RPPreviewViewController) {
        previewController.dismiss(animated: true, completion: nil)
    }
}

4. 不预览直接保存录制内容

RPScreenRecorder.shared().startCapture { sampleBuffer, bufferType, error in
    if let error = error {
        print("Error capturing: \(error.localizedDescription)")
        return
    }

    // 处理视频和音频数据
    if bufferType == .video {
        print("Captured video frame.")
    } else if bufferType == .audioApp || bufferType == .audioMic {
        print("Captured audio frame.")
    }
} completionHandler: { error in
    if let error = error {
        print("Error starting capture: \(error.localizedDescription)")
    } else {
        print("Capture started successfully.")
    }
}
