Example Project

To try the example project, simply clone this repository and open ARVideoKit-Example.xcodeproj project file.

It's recommended to test SKViewController by assigning it as the initial view controller.

Installation

Manual

Drag the ARVideoKit.framework file as an embedded binary of your project targets. ARVideoKit.framework can be found in the /Framework/ folder of this repository.

Implementation

1. import ARVideoKit in the application delegate AppDelegate.swift and a UIViewController with an ARKit scene.

2. In the application delegate AppDelegate.swift, add this in order to allow the framework access and identify the supported device orientations. Recommended if the application supports landscape orientations.

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
return ViewAR.orientation
}

1. In the selected UIViewController class, create an optional type RecordAR global variable.

var recorder:RecordAR?

1. Initialize RecordAR with ARSCNView or ARSKView. Recommended to initialize in viewDidLoad().

Initializing RecordAR with ARSCNView

recorder = RecordAR(ARSceneKit: sceneView)

Initializing RecordAR with ARSKView

recorder = RecordAR(ARSpriteKit: SKSceneView)

1. Call the prepare() method in viewWillAppear(_ animated: Bool)

let configuration = ARWorldTrackingConfiguration()
recorder?.prepare(configuration)

1. Call the rest() method in viewWillDisappear(_ animated: Bool)

recorder?.rest()

1. Call the record() method in the proper method to start recording.

@IBAction func startRecording(_ sender: UIButton) {
recorder?.record()
}

1. Call the stopAndExport() method in the proper method to stop recording.

@IBAction func stopRecording(_ sender: UIButton) {
recorder?.stopAndExport()
}

NOTE

Make sure you add the usage description of the camera, microphone, and photo library in the app's Info.plist.

<key>NSCameraUsageDescription</key>
<string>AR Camera</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>Export AR Media</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Export AR Media</string>
<key>NSMicrophoneUsageDescription</key>
<string>Audiovisual Recording</string>

You're all set.
