-For iOS, all you need to do is specify the permissions in your `ios/[project]/Info.plist` file:
233 
+On iOS, you are going to have to supply your own code to download files. You can supply an `onFileDownload` callback
234 
+to the WebView component as a prop. If RNCWebView determines that a file download needs to take place, the URL where you can download the file
235 
+will be given to `onFileDownload`. From that callback you can then download that file however you would like to do so.
236 
+
237 
+Example:
238 
+```javascript
239 
+  onFileDownload = ({ nativeEvent }) => {
240 
+    const { downloadUrl } = nativeEvent;
241 
+    // --> Your download code goes here <--
242 
+  }
243 
+```
234
244
235 
-Save to gallery:
245 
+To be able to save images to the gallery you need to specify this permission in your `ios/[project]/Info.plist` file:
236
246
237 
 ```
 247 
 ```

 <key>NSPhotoLibraryAddUsageDescription</key>

-Add permission in AndroidManifest.xml:
254 
+On Android, integration with the DownloadManager is built-in.
255 
+All you have to do to support downloads is add these permissions in AndroidManifest.xml:
245
256
246 
 ```xml
 257 
 ```xml
247 
 <manifest ...>
 258 
 <manifest ...>
