Write file doesn't save base64 string on IOS, how to fix it ?

[andriiradkevych]

import RNFetchBlob from 'rn-fetch-blob';
import {Platform} from 'react-native';

import {generateUuid} from './helpers';

export const saveImageBase64 = async (
  base64String: string,
  successCallback: () => void,
) => {
  const fileName = `${generateUuid()}.png`;
  const dirs = RNFetchBlob.fs.dirs;

  const Base64Code = base64String.split('data:image/png;base64,');

  const filePath = `${
    Platform.OS === 'android' ? dirs.DownloadDir : dirs.DocumentDir
  }/${fileName}`;

  RNFetchBlob.fs
    .writeFile(filePath, Base64Code[1], 'base64')
    .then(() => {
      if (Platform.OS === 'ios') {
        RNFetchBlob.ios.openDocument(filePath);
      } else {
        successCallback();
      }
    })
};

What I have here is saveImageBase64 function , that perfectly works on Android , it saves my image , and I'm happy , but on ios , function doesn't send any error , seems like all is working well , but when I try to open this image by RNFetchBlob.ios.openDocument(filePath); , it just show me :

what does it mean ? and could someone show me how can I save my file , and open it , or just save on ios , because I don't see that anything saved to my Document dir

  const baseWithoutSpaces = Base64Code[1].replace(/\r?\n|\r/g, '');

  RNFetchBlob.fs
    .writeFile(filePath, baseWithoutSpaces, 'base64')
    

Found fix , hope it will help someone
