ReplayKit with SwiftUI - ios

Question

I want to record the screen with ReplayKit.
I have researched the method with UIKit. But my project used SwiftUI, so I want to use the ReplayKit to record the screen with SwiftUI.
How I record the screen with SwiftUI?
-
When I use the stopRecording function, the function will have previewViewController. But I cannot call present function to present previewViewController.

Answer 1

Note: This is not a very practical answer.
In most cases, "SwiftUI.View" runs on top of "UIHostingController".
You need to grab this to present the "RPPreviewViewController".
You can find one of them by following the "UIApplication".
let scene = UIApplication.shared.connectedScenes.first as! UIWindowScene
let viewController = scene.windows.last!.rootViewController
viewController.present(previewViewController, animated: true, completion:nil)

Answer 2

I have just open-sourced a simple ReplayKit application, which uses SwiftUI.
https://github.com/snakajima/ReplayStartUpKit
Please take a look at how it presents a RPBroadcastActivityViewController from SwiftUI.
It first stores the pointer to the controller in a property bavController, then set #Pubilshed property activePopup to initiate SwiftUI change.
RPBroadcastActivityViewController.load { controller, error in
if let controller = controller {
self.bavController = controller
controller.delegate = self
self.activePopup = .broadCast
}
}
In SwiftUI (MainUIView.swift), the following view is activated when the property activePopup becomes .broadCast.
.sheet(item: $state.activePopup) { item in
switch(item) {
case .broadCast:
BroadcastActivityController(controller: state.bavController!)
}
}
BroadcastActivityController is bit long because of a work-around for iPad, but it is just a wrapper of RPBroadcastActivityController.
struct BroadcastActivityController: UIViewControllerRepresentable {
let controller: RPBroadcastActivityViewController
func makeUIViewController(context: Context) -> RPBroadcastActivityViewController {
return controller
}
func updateUIViewController(_ uiViewController: RPBroadcastActivityViewController, context: Context) {
// Hack to work around iPad issue
if UIDevice.current.userInterfaceIdiom == .pad {
guard let sceneDelegate = UIApplication.shared.connectedScenes.first?.delegate as? SceneDelegate,
let vc = sceneDelegate.uiWindow?.rootViewController,
let view = vc.view else {
print("somethign is really wrong")
return
}
controller.modalPresentationStyle = .popover
if let popover = controller.popoverPresentationController {
popover.sourceRect = CGRect(origin: .zero, size: CGSize(width: 10, height: 10))
popover.sourceView = view
popover.permittedArrowDirections = []
}
}
}
typealias UIViewControllerType = RPBroadcastActivityViewController
}
You need to do something very similar to previewViewController.

Try This
import SwiftUI
import ReplayKit
struct ContentView: View {
let recorder = RPScreenRecorder.shared()
#State var isBool = false
#State var rp: RPPreviewView!
#State var isRecording = false
#State var isShowPreviewVideo = false
var body: some View {
ZStack {
VStack {
Button(action: {
if !self.isRecording {
self.startRecord()
} else {
self.stopRecord()
}
}) {
Image(systemName: isRecording ? "stop.circle" : "video.circle")
.resizable()
.frame(width: 100, height: 100)
}
}
if isShowPreviewVideo {
rp
.transition(.move(edge: .bottom))
.edgesIgnoringSafeArea(.all)
}
}
}
func startRecord() {
guard recorder.isAvailable else {
print("Recording is not available at this time.")
return
}
if !recorder.isRecording {
recorder.startRecording { (error) in
guard error == nil else {
print("There was an error starting the recording.")
return
}
print("Started Recording Successfully")
self.isRecording = true
}
}
}
func stopRecord() {
recorder.stopRecording { (preview, error) in
print("Stopped recording")
self.isRecording = false
guard let preview = preview else {
print("Preview controller is not available.")
return
}
self.rp = RPPreviewView(rpPreviewViewController: preview, isShow: self.$isShowPreviewVideo)
withAnimation {
self.isShowPreviewVideo = true
}
}
}
}
struct RPPreviewView: UIViewControllerRepresentable {
let rpPreviewViewController: RPPreviewViewController
#Binding var isShow: Bool
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
func makeUIViewController(context: Context) -> RPPreviewViewController {
rpPreviewViewController.previewControllerDelegate = context.coordinator
rpPreviewViewController.modalPresentationStyle = .fullScreen
return rpPreviewViewController
}
func updateUIViewController(_ uiViewController: RPPreviewViewController, context: Context) { }
class Coordinator: NSObject, RPPreviewViewControllerDelegate {
var parent: RPPreviewView
init(_ parent: RPPreviewView) {
self.parent = parent
}
func previewControllerDidFinish(_ previewController: RPPreviewViewController) {
withAnimation {
parent.isShow = false
}
}
}
}
