#import "GTLDrive.h"
// ...

+ (void)printAboutWithService:(GTLServiceDrive *)service {
  GTLQueryDrive *query = [GTLQueryDrive queryForAboutGet];
  // queryTicket can be used to track the status of the request.
  GTLServiceTicket *queryTicket =
    [service executeQuery:query
        completionHandler:^(GTLServiceTicket *ticket, GTLDriveAbout *about,
                            NSError *error) {
          if (error == nil) {
            NSLog(@"Current user name: %@", about.name);
            NSLog(@"Root folder ID: %@", about.rootFolderId);
            NSLog(@"Total quota (bytes): %@", about.quotaBytesTotal);
            NSLog(@"Used quota (bytes): %@", about.quotaBytesUsed);
          } else {
            NSLog(@"An error occurred: %@", error);
          }
        }];
}
