React native html to pdf - ios

Question

I am using this code and it works fine in simulator as I am getting a location and can get pdf file from there
async createPDF() {
let options = {
html: '<h1>PDF TEST</h1>',
fileName: 'test',
directory: 'Documents',
};
let file = await RNHTMLtoPDF.convert(options)
// console.log(file.filePath);
alert(file.filePath);
}
But the above code problem in the real iOS mobile as it is saving the pdf file somewhere. I don’t know where but I am not able to see that file in my mobile. So can anyone tell me how can I save my file in the downloads or documents in the iOS . So that I can see the downloaded file.

Answer 1

Found the answer to convert file in base64 string

Answer 2

You can solve this issue by using base64 as the following:
let options = {
html:
`
<h2 style="text-align: center">${'Some text and dynamic value'}</h2>
`,
fileName: 'TestingPDF',
directory: 'Documents',
base64: true
};
let file = await RNHTMLtoPDF.convert(options);
You shoud use 'react-native-file-access' to copy the file and move it to Downloads directory, so let's install it by: npm i react-native-file-access --save
Lets copy the file to the Downloads directory by the following:
const fileName = 'PMA_CurrentBalanceFile.pdf'; //whatever you want to call your file
const filePath = `${Dirs.DocumentDir}/${fileName}`;
const base64Data = file.base64; //our base64 encode file which done by RNHTMLtoPDF;
Then write the following code to do your job:
if (Platform.OS === 'android') {
const permissionGranted = await permissionWriteExternalStorage();
if (permissionGranted) {
await FileSystem.writeFile(filePath, base64Data, 'base64');
if (!FileSystem.exists(filePath)) return;// check to see if our filePath was created
await FileSystem.cpExternal(filePath, fileName,'downloads');// copies our file to the downloads folder/directory
// file should now be visible in the downloads folder
ToastAndroid.show("", "One File Downloaded", ToastAndroid.SHORT);
}
return;
}
if (Platform.OS === 'ios') {
// IOS version
await FileSystem.writeFile(filePath, base64Data, 'base64');
Alert.alert('', 'One File Downloaded');
}
