• Answer:

  check this link http://code.google.com/p/gtm-oauth2/ and here is a sample code of finishedWithAuth (void)viewController:(GTMOAuth2ViewControllerTouch *)viewController finishedWithAuth:(GTMOAuth2Authentication *)auth error:(NSError *)error { if (error != nil) { // Authentication failed (perhaps the user denied access, or closed the // window before granting access) NSLog(@"Authentication error: %@", error); NSData *responseData = [[error userInfo] objectForKey:@"data"]; // kGTMHTTPFetcherStatusDataKey if ([responseData length] > 0) { // show the body of the server's authentication failure response NSString *str = [[[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding] autorelease]; NSLog(@"%@", str); } self.auth = nil; } else { // Authentication succeeded // // At this point, we either use the authentication object to explicitly // authorize requests, like // // [auth authorizeRequest:myNSURLMutableRequest // completionHandler:^(NSError *error) { // if (error == nil) { // // request here has been authorized // } // }]; // // or store the authentication object into a fetcher or a Google API service // object like // // [fetcher setAuthorizer:auth]; // save the authentication object self.auth = auth; } }
