FrontCameraView

A preview front camera UIView in Swift

Features

• Preview front camera
• Move the preview UIView to every corner of the screen.
• Record video

Configure Your App's Info.plist File

iOS requires that your app provides static messages to be displayed to the user when the system asks for camera or microphone permission.

Include the NSCameraUsageDescription and NSMicrophoneUsageDescription key in your app’s Info.plist file.

For each key, provide a message that explains to the user why your app needs to capture media, so that the user can feel confident granting permission to your app.

Check for camera authorization

In your viewDidAppear, add the following code for asking authorization to use the camera(if user has revoked authorization)

if let alertCheckAuthorization = capturePreview?.checkCameraAuthorization() {
            self.present(alertCheckAuthorization, animated: true, completion: nil)
        } else {
            capturePreview?.startPreview(completion: { (_) in
            // Do something ...
            })
        }

Requirements

Works on portrait mode

Usage

Manually

• Drag FrontCameraView.swift and CameraManager.swift into your project
• In your ViewController add the following code

    var capturePreview: FrontCameraView?

    override func viewDidLoad() {
        super.viewDidLoad()

        capturePreview = FrontCameraView(frame: CGRect(x: self.view.frame.size.width/2,
                                                       y: self.view.frame.size.height/2,
                                                       width: self.view.frame.size.width/4,
                                                       height: self.view.frame.size.height/4))
        capturePreview?.delegate = self


    }

    override func viewDidAppear(_ animated: Bool) {

        self.view.addSubview(capturePreview!)
        if let alertCheckAuthorization = capturePreview?.checkCameraAuthorization() {
            self.present(alertCheckAuthorization, animated: true, completion: nil)
        } else {
            capturePreview?.startPreview(completion: { (_) in
            // Do something ...
            })
        }
    }

Recording video

I've added a Record Button from here. Simply add this code to viewDidLoad and viewDidAppear

    var recordButton: RecordButton?
    override func viewDidLoad() {
      .
      .
      .
      let recordButtonSide = self.view.bounds.size.height/10
      recordButton = RecordButton(frame: CGRect(x: self.view.bounds.width/2-recordButtonSide/2,
                                                y: self.view.bounds.height/2-recordButtonSide/2,
                                                width: recordButtonSide,
                                                height: recordButtonSide))
      recordButton?.delegate = self

    }
    override func viewDidAppear(_ animated: Bool) {
      .
      .
      .
      self.view.addSubview(recordButton!)

    }

and conform to RecordButtonDelegate protocol.

extension ViewController: RecordButtonDelegate {

    func tapButton(isRecording: Bool) {

        if isRecording {
            capturePreview?.startRecording()
        } else {
            capturePreview?.stopRecording()
        }
    }
}

Delegate

The ViewController should conform FrontCameraViewDelegate protocol to know when the video has been recorded.

extension ViewController: FrontCameraDelegate {

    func videoRecorded(atURL: URL?) {
        guard let url = atURL else { return }
        print("Video has been recorded at: \(url)")
    }

}
