Actually i followed this link google drive sdk for develoeprs
And i configured all things what they mentioned in the above link. But the problem i am facing was the sample app DrEdit was not listing the text files on ios simulator after logged in and after i gave the permission "Allow Access" even i am having some text files in my google drive. Any thing i did wring here?. My another doubt was why there is a difference between DocuDign Ink ios app permissions and DrEdit app permissions. Please check the screen shots here i attached one i took it from DrEdit from simulator and another one from DocuSign Ink ios app from my iPad.
Note:
DrEdit app shows the permissions: "View and manage Google Drive files that you have opened or created with this app". But I would like to see the permission like this: "view and manage any of your documents and files in Google Drive". How and where I can change the permission?
