React Native : Download and open pdf file, need to work on IOS and Android

Question

Using react native I am trying to download a PDF file (Sample PDF File). After download completes, it should open with 3rd party pdf viewer

Please guide me how to do this in react native.

Answer 1

1) Download base64 encoded pdf file.

2) Decode base64 encoded file ( I suggest you use react-native filehandler)

3)In order to view pdf you can use webview on IOS

     <WebView style={{
          flex: 1
        }}  scalesPageToFit={true} source={{
          uri: --base64EncodedContent--
        }}
        >
       </WebView>

for android you can use react-native pdf view https://github.com/cnjon/react-native-pdf-view

     <PDFView 
        path={this.props.src} //path of pdf file you saved
        pageNumber={1}
        onLoadComplete = {(pageCount) => {

        }}
        style={styles.pdf}>
        </PDFView>
