CameraRoll.getPhotos return just a few on iOS

Environment

Environment: OS: Linux 4.15 Node: 10.6.0 Yarn: 1.7.0 npm: 6.1.0 Watchman: Not Found Xcode: N/A Android Studio: Not Found

Description

The CameraRoll.getPhotos function only returns some photos on iOS, while it works perfectly on Android. For example, if I use the following parameters

{
  first: 100,
  assetType: 'All',
  groupTypes: 'All',
}

I only get 39 photos, while I have more than a thousand in my camera roll. I have also tried with multiple different parameters, but the result is the same (or fewer photos because of a filter).

Reproducible Demo

• I think it must be run on a physical iOS device, because it has to access the camera roll.
• The demo prints the length of response.length, where response is the resolved value of CameraRoll.getPhotos with the parameters I mentioned earlier.

Unless people’s environments are starkly different from mine the switch will fix it. My app uses PHPhotoLibrary’s PHAsset.fetch to get the IDs using bridge Swift code, then string manipulation to turn them into ALAssetsLibrary style URIs.

Everything else in React (Image tag, upload libraries, custom image tags, etc) will work just fine with ALAssetsLibrary URIs even if CameraRoll couldn’t find them to begin with. They will not work with PHAssets. Live photo/burst get treated as their key frame single image.

I think the harder part of switching CameraRoll over is that everything else in React has to follow suit. It will require switching CameraRoll to have an option for whether it gives PHAssets or ALAssets, even if the only difference ends up being some string manipulation of the URI format.

@hramos What is the process for getting something like that done? I’ve never worked on React Native itself before.

On top of that, it seems that Image still does not work with photos://uuid URIs given by PHAsset and on some models of phone assets-library://uuid URIs have stopped working.

@airlaser Can you post these as separate issues please? No-one is tracking this closed issue.
