Use this method when you get the oauth object to save into keychain

[GTMOAuth2ViewControllerTouch saveParamsToKeychainForName:YOUR_KEYCHAIN_ITEM_NAME authentication:auth];

and

before making a call to api just check and retrieve the oauth object using this

GTMOAuth2Authentication * auth = [GTMOAuth2ViewControllerTouch
                                      authForGoogleFromKeychainForName:YOUR_KEYCHAIN_ITEM_NAME
                                      clientID:GOOGLE_CLIENT_KEY
                                      clientSecret:GOOGLE_CLIENT_SECRET];

and make sure it's oauth object is authentic with using this

if(![GTMOAuth2ViewControllerTouch authorizeFromKeychainForName:YOUR_KEYCHAIN_ITEM_NAME authentication:auth])
