Outline

• feat: Adding a Camera to the Screen #1

Work Contents

• Add a view to float the camera on the storyboard.
• Add camera permission to the info.
• Add code to display camera on image

Trouble Point

1. Select the camera to film the Sudoku problem

• �Trouble Situation
  • Wanted to use only the best camera to shoot Sudoku.
  • Many types of cameras, so the only way was to enter the code and check it.
  • builtInWideAngleCamera, builtInUltraWideCamera, builtInTelephotoCamera, builtInDualCamera, builtInDualWideCamera, builtInTripleCamera

• Trouble Shooting
  • Put builtInDualCamera, builtInDualWideCamera, builtInTripleCamera in, the camera didn't work, and builtInWideAngleCamera, builtInTelephotoCamera were cameras that were not suitable for Sudoku shooting.
    • applied builtInUltraWideCamera because it was suitable for camera shooting.

AVCaptureDevice.default(.builtInUltraWideCamera, for: .video, position: .back)

2. Convert image to bgra type that is easy to control with pixel buffer

• �Trouble Situation

[String: NSNumber(value: kCVPixelFormatType_32BGRA)]

• If insert kCVPixelFormatType_32BGRA right away, a type error occurs.

• Trouble Shooting
  • Upcast kCVPixelBufferPixelFormatTypeKey to AnyHashable and downcast AnyHashable again to solve the type error.

[kCVPixelBufferPixelFormatTypeKey as AnyHashable as! String: NSNumber(value: kCVPixelFormatType_32BGRA)]

카메라 관련 사항은 추후 외부에서 변경할 예정이 없다면 private를 붙이면 좋을 것 같아요👍

생각하지 못했던 부분이네요. 감사합니다!

고생하셨습니다 코인! :)

코드를 읽으며 궁금한 점을 리뷰로 남겨봤어요.
저도 AVCaptureVideoDataOutputSampleBufferDelegate 에 공부해볼 수 있어서 좋았습니다! 👍
고생 많으셨어요~
