working good the files are storing as expected, Today agin I am checking, every time I am getting error meesage. please find the console message
An error occurred: Error Domain=com.google.GTLJSONRPCErrorDomain
Code=400 "The operation couldn’t be completed. (Unsupported content
with type: application/json-rpc; charset=utf-8)" UserInfo=0x75b11f0
{error=Unsupported content with type: application/json-rpc;

if this is happen with the sample code it self how could be the Google API for iOS reliable to integrate in our apps.

Very recent changes in the Google Drive service obliges you to specify a mime type different than "application/json-rpc" when uploading a file. This mime type is used by default when using the ObjectiveC SDK, so you need to specify one.
To make the sample that ships with the SDK work, open DriveWindowController.m and in the "uploadFileAtPath:" method under "newFile.title = filename;" add "newFile.mimeType = #"image/png";". Change "image/png" to the MIME type of the file you are uploading.
GTLDriveFile *newFile = [GTLDriveFile object];
newFile.title = filename;
newFile.mimeType = #"image/png";
Edited: It also seems that there is temporary problem on Google's servers
