Integration

Implementing the Biometric Capture Session in a View-based UI​

This example shows how to integrate the Biometric Capture Session to your project. The Biometric Capture Session extracts a frames collection from the camera preview.

Create View inside ViewController.​

After finishing the import of MobaiBiometric inside the project now you can import library inside the swift file .

import MobaiBiometric

In the UI for this example app, we use the following:

Create view 

private var mbCaptureSessionView: MBCaptureSessionView

Initialization view whith MBCaptureSessionOptions

public init() {
    self.options = MBCaptureSessionOptions()
    self.mbCaptureSessionView = MBCaptureSessionView(options: self.options)
}

Setup View Constraints

view.addSubview(takePictureButton)
        
NSLayoutConstraint.activate([
    mbCaptureSessionView.topAnchor.constraint(equalTo: view.topAnchor),
    mbCaptureSessionView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
    mbCaptureSessionView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
    mbCaptureSessionView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
])

Starts Camera if camera permissions are granted 

public override func viewWillAppear(_ animated: Bool) {
    mbCaptureSessionView.onStartCapturing()
}

Stop Capturing

public override func viewWillDisappear(_ animated: Bool) {
    mbCaptureSessionView.onStopCapturing()
}

Adding delegate and implement the delegate inside View Controller

mbCaptureSessionView.delegate = self

extension ExampleViewController: MBCaptureSessionDelegate {

}

Calling ViewController.​

Initialization and calling present of MBCaptureSessionViewController 

let viewController = MBCaptureSessionViewController(options: .init())
viewController.delegate = self
self.present(viewController, animated: true, completion: nil)

MBCaptureSessionDelegate​

onCompleted is executed for MBCaptureSession class when the capture session is successfully finished

public func onCompleted(result: MBCaptureSessionResult)  {
        
}

onWaiting is executed for DetectedFaceStatus class when the face is not in right circle

public func onWaiting(faceStatus: DetectedFaceStatus) {

}

onStarted is executed when when camera capture started

public func onStarted() { 

}

onFailure is executed for MBCaptureSessionService class when the camera can not be

public func onFailure(error: MBCaptureSessionError) {

}
