Users who want to access their Google Drive files on the go will be able to do so on their iOS device soon enough. Google has opened the software development kit (SDK) to Apple platforms, in addition to Android.
A fresh post
on the Google Developers Blog specifically states, “Today, we're announcing full mobile support for Android and iOS apps using the Drive SDK.”
Integration with Google Drive will allow iPhone and iPad owners to read and write files directly to Google Drive, as well as “Open with” Drive “to view or edit content from their phone or tablet just like they do on the web.”
