iOS에서 .NET MAUI로 바코드 읽고 쓰기

위의 MainPage.xaml 코드에서 우리는 체크박스가 생성된 바코드와 QR 코드가 PDF 형식으로 되어야 하는지 여부를 결정하는 것을 볼 수 있습니다. 다음으로, 라이센스 키를 설정합니다. 이 단계에서는 체험판 또는 유료 라이센스 키를 사용해 주세요.

코드는 barcodeInput 변수에서 값을 확인하고 가져온 다음, CreateBarcode 메서드를 사용하여 바코드를 생성합니다. 마지막으로, Android와 iOS 모두에 적합한 파일을 저장하는 SaveToDownloadsAsync 메서드를 호출합니다.

iOS에서는 파일 애플리케이션으로 문서를 내보내기 위해 사용자 지정 파일 경로가 필요합니다.
