Swift4でインカメラの使用

More than 1 year has passed since last update.

Swift4でインカメラのを取得して使用。
備忘録なので当該箇所のみ。

var captureDevice: AVCaptureDevice?
    let discoverySession = AVCaptureDevice.DiscoverySession(deviceTypes: [.builtInWideAngleCamera, .builtInTelephotoCamera],
                                                            mediaType: AVMediaType.video,
                                                            position: .front)
    for device in discoverySession.devices {
        let devicePosition: AVCaptureDevice.Position = .front
        if (device as AnyObject).position == devicePosition {
            captureDevice = device
        }
    }
    if captureDevice == nil {
        print("Error: no camera devices available")
        return false
    }

    guard let videoInput = try? AVCaptureDeviceInput(device: captureDevice!) else {
      print("Error: could not create AVCaptureDeviceInput")
      return false
    }
  • .builtInTelephotoCamera は要らない気がするが念のため。
  • あとは videoInputAVCaptureSession にセットしてよしなにする。
