Object c List of files from a Google drive

Develops an ios app, including Google. In Google Drive, when I try to list files, it displays all folders, subfolders, subfiles on one page. This is my code.

GTLQueryDrive *query = [GTLQueryDrive queryForFilesList];

    [driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,
                                                         GTLDriveFileList *filesList,
                                                         NSError *error) {
if (error == nil) {

            [FilesFromGoogleDrive addObjectsFromArray:filesList.items
             ];

        };

I do not want to list all the files on the main page. I need, like Google’s application, to access folders, subfolders, subfiles in a consistent way. Try it from last week, but there is no good result. So please help me how to access folders, subfolders.

To get a list of all Google Drive files, use the code below:

GTLQueryDrive *query = [GTLQueryDrive queryForFilesList];
query.q = [NSString stringWithFormat:@"'%@' IN parents", @"root"];

[self.serviceDrive executeQuery:query completionHandler:^(GTLServiceTicket *ticket,
                                                          GTLDriveFileList *files,
                                                          NSError *error) {

    if (error == nil)
    {
        NSMutableArray * driveFiles = [[NSMutableArray alloc] init];
        [driveFiles addObjectsFromArray:files.items];

        for (GTLDriveFile *file in driveFiles)
            NSLog(@"File is %@", file.title);

    }
    else
    {
        NSLog(@"An error occurred: %@", error);
    }
}];
