I have implemented a PDFView in the app but it is unable to show the pdf downloaded from the web service. If I add a bundle resource in the project it loads it fine. But the one from the API is not loaded. I have added the code below to check further.
struct UploadQuotationView: View {
let frId: String = "FR-DEMO-062021-00116"
@State var downloadURL = URL(string: "https://www.apple.com")
// @State var fileURL = Bundle.main.url(forResource: "c4611_sample_explain", withExtension: "pdf")
@State var docSheet = false
@State var pdfView = PDFKitRepresentedView(Data())
@State var data = Data()
var body: some View {
VStack{
Button("View PDF"){
//downloadFile()
downloadAndView(fileName: "Quotation\(frId)")
//fileURL = Bundle.main.url(forResource: "fileSample", withExtension: "pdf")
}
.onAppear(){
// downloadAndView(fileName: "Quotation\(frId)")
}
.padding()
PDFKitRepresentedView(data)
.cornerRadius(10)
.padding()
.shadow(radius: 10)
Button("document picker"){
docSheet.toggle()
}
.sheet(isPresented: $docSheet) {
DocumentPickerView()
}
.padding()
}
}
func downloadAndView(fileName:String) {
guard let url = URL(string: "\(CommonStrings().apiURL)faultreport/quotation/\(frId)") else {return}
var urlRequest = URLRequest(url: url)
urlRequest.httpMethod = "GET"
urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
urlRequest.setValue(UserDefaults.standard.string(forKey: "token"), forHTTPHeaderField: "Authorization")
urlRequest.setValue(UserDefaults.standard.string(forKey: "role"), forHTTPHeaderField: "role")
urlRequest.setValue( UserDefaults.standard.string(forKey: "workspace"), forHTTPHeaderField: "workspace")
print(urlRequest)
let dataTask = URLSession.shared.dataTask(with: urlRequest) { (data, response, error) in
if let error = error {
print("Request error: ", error)
return
}
guard let response = response as? HTTPURLResponse else {
print("response error: \(String(describing: error))")
return
}
if response.statusCode == 200 {
if let pdfData = data {
print("success")
//pdfView = PDFKitRepresentedView(pdfData)
self.data = pdfData
}
}else{
print("Error: \(response.statusCode). There was an error")
}
}
dataTask.resume()
}
}
struct PDFKitRepresentedView: UIViewRepresentable {
let pdfView = PDFView()
let data: Data
init(_ data: Data) {
self.data = data
}
func makeUIView(context: UIViewRepresentableContext<PDFKitRepresentedView>) -> PDFKitRepresentedView.UIViewType {
pdfView.document = PDFDocument(data: data)
pdfView.displayMode = .singlePage
pdfView.displayDirection = .horizontal
return pdfView
}
func updateUIView(_ uiView: UIView, context: UIViewRepresentableContext<PDFKitRepresentedView>) {
pdfView.document = PDFDocument(data: data)
}
}
There are some variables that you can modify as per your liking like the api URL and similar.
I have added the screenshot that shows the data is loaded in the "data" variable when the API request is success. Please check the screenshot.
