[IOS] Error saving to disk: "Could not write file: You don't have permission to save the file..."

[victorbadila]

Hi, I'm trying to use ImageCrop with local file saving options:

<ImageCrop
  ref={(c) => { this.cropper = c; }}
  zoom={this.state.zoom}
  image={this.props.image}
  cropHeight={this.props.height}
  cropWidth={this.props.width}
  panToMove
  format="file"
  filePath="abc.jpg"
  pinchToZoom
/>

When I invoke this.cropper.crop() the returned Promise gets rejected "Could not write file: You don't have permission to save the file "abc.jpg"."
I presume it has something to do with declared permissions in Info.plist but I couldn't find anything related on the web. If there is a simple answer to this it would be worth adding it to the README documentation.

Somewhat related to the following: #39

This should be adressed in gl-react-native if you have any problems..
It is the permissions you struggle with..

Hi - can you point me in the right direction of where to look so i can enable the right permissions to make this work?

Currently trying using the following props/config and i'm getting a similar error, but i cannot find anything on how to fix it.

<ImageCrop format={'file'} filePath={'avatar.jpg'} ref={"cropper"} image={this.state.image.uri} cropHeight={third} cropWidth={third} zoom={0} maxZoom={80} minZoom={0} panToMove={true} />

what i said ^^

Hey @Stoffern - i've looked all through the gl-react-native repo and couldn't see anything about how to address it.

I assume it's this repo, yes? https://github.com/gre/gl-react-native-v2

Anything you could point me to would be helpful - i realise it's not in the scope of your repo, but it
may be a common issue that i can contribute back to the readme once i've overcame it.

https://github.com/gre/gl-react-v2/blob/master/docs/api/Surface.md

in gl-react-native, format: "file" allows to save to a file. You also need to provide a filePath String (you should use react-native-fs to knows directory paths). The promise result will be a file://... url that you can use in

So you use react-native-fs to provide correct paths?

[danmatthews]

I don't, I use Expo's filesystem API, as i'm using Expo (detached to Expokit) - they produce filesystem URLs that seem to match the ones in the react-native-fs package, but i'll try and install react-native-fs and see if it solves my problem.

If it works, is it okay to submit a PR to the README to provide more information? It might help a few people out.
