React-native-fetch-blob: openDocument not working on iOS

[raminious]

RNFetchBlob.ios.openDocument: Not worked without throwing any error. it only return null result on success promise.
It also not throw error when file is not exists.

iOS: 10 (simulator)
react-native: 0.34.1
path: /Users/raminious/Library/Developer/CoreSimulator/Devices/AFCFB1EA-23C3-4B77-961C-CC431B55D4CF/data/Containers/Data/Application/324FD0EB-73B7-4EE7-9254-3C4B67857D92/Documents/myvid.mp4

I'm not iOS developer but I changed

presentOpenInMenuFromRect:rootCtrl.view.bounds inView:rootCtrl.view

to

presentOptionsMenuFromRect:rootCtrl.view.bounds inView:rootCtrl.view

And now it's working.

@raminious , thanks for the information, I'll try to change the implementation 👍

[raminious]

Thanks @wkh237
I think as you documented openDocument must open file directly with associated app and previewDocument must show action menu for interact with the file (presentOptionsMenuFromRect)
Currently these functions are working vice versa.

Thanks for the advice, if the naming is confusing, I think it's okay to change their name 😄 I'll make these changes and publish another package to npm.

@raminious , I've published 0.10.0-beta.3 to npm, please upgrade to this version and verify the changes, thank you !

Thanks @wkh237

One more very important thing... the path must have an extension on the end or it won't work.

e.g. RNFetchBlob.ios.openDocument('path/to/file.ext');

the same is true for previewDocument( ). If your path doesn't have an extension, you can append the extension type on the end of the path using the .config method:

    RNFetchBlob
    .config({
      fileCache: true,
      appendExt: 'jpg', // only append an extension if the res.path() does not return one
    })
    .fetch('GET', attachmentUrl, {
      Authorization: AuthorizationStore.getAuthHeaderValue(),
    })
    .then((res) => {
      // console.log(res.path()) // uncomment this to check if your path has an extension on the end of it
      if (Platform.OS === 'ios') {
        RNFetchBlob.ios.openDocument(res.path()); // results in path/to/file.jpg
      }
    });

I filed the same issue here: https://github.com/wkh237/react-native-fetch-blob/issues/195
