Android devices allow you to use the cordova-filechooser which works awesome.
It lets you interact with google drive and even dropbox, plus all the local filesystem.
However when it comes to IOS I can’t seem to find a a package that does something similar.
Ideally need to connect to photos / dropbox / google drive on an ios device to get files and attach them / upload them into our app / service.
I am not seeing much in the way of plugin support for something like this.
