如何以编程方式录制IOS屏幕

有没有办法以编程方式录制 IOS 屏幕？意味着您正在执行的任何活动，例如单击按钮、滚动表格视图。

即使正在播放的视频会与其他活动一起再次捕获？

尝试过这些

但这些库不会提供高质量的视频。我需要高质量的视频。

问题是，当我捕获屏幕时在后台播放视频时，它不会显示流畅的视频。它显示一帧视频，然后 3-4 秒后显示第二帧，依此类推。而且视频质量不好，很模糊

从 iOS 9 开始，ReplayKit 似乎可以大大简化这一过程。

Update：既然 iOS 11 有内置的屏幕录像机，这可能不太相关，但以下内容Swift 3代码对我有用：

import ReplayKit

@IBAction func toggleRecording(_ sender: UIBarButtonItem) {
    let r = RPScreenRecorder.shared()

    guard r.isAvailable else {
        print("ReplayKit unavailable")
        return
    }
    
    if r.isRecording {
        self.stopRecording(sender, r)
        
    }
    else {
        self.startRecording(sender, r)
    }
}

func startRecording(_ sender: UIBarButtonItem, _ r: RPScreenRecorder) {
    
    r.startRecording(handler: { (error: Error?) -> Void in
        if error == nil { // Recording has started
            sender.title = "Stop"
        } else {
            // Handle error
            print(error?.localizedDescription ?? "Unknown error")
        }
    })
}

func stopRecording(_ sender: UIBarButtonItem, _ r: RPScreenRecorder) {
    r.stopRecording( handler: { previewViewController, error in

        sender.title = "Record"
        
        if let pvc = previewViewController {

            if UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.pad {
                pvc.modalPresentationStyle = UIModalPresentationStyle.popover
                pvc.popoverPresentationController?.sourceRect = CGRect.zero
                pvc.popoverPresentationController?.sourceView = self.view
            }

            pvc.previewControllerDelegate = self
            self.present(pvc, animated: true, completion: nil)
        }
        else if let error = error {
            print(error.localizedDescription)
        }
        
    })
}

// MARK: RPPreviewViewControllerDelegate
func previewControllerDidFinish(_ previewController: RPPreviewViewController) {
    previewController.dismiss(animated: true, completion: nil)
}
