Oi eu integrei o Google Dive com meu aplicativo usando o código de exemplo do Dr. Edit do Google Drive. Mas não consigo visualizar todos os arquivos armazenados em minha conta do Google Drive.

// Eu tentei isso

-(void)getFileListFromSpecifiedParentFolder 
{
GTLQueryDrive *query2 = [GTLQueryDrive queryForChildrenListWithFolderId:@"root"];
query2.maxResults = 1000;


[self.driveService executeQuery:query2
              completionHandler:^(GTLServiceTicket *ticket,
                                  GTLDriveChildList *children, NSError *error) 
{
 NSLog(@"\nGoogle Drive: file count in the folder: %d",   children.items.count);

if (!children.items.count) 
{
    return ;
}

if (error == nil) 
{
for (GTLDriveChildReference *child in children) 
{

GTLQuery *query = [GTLQueryDrive queryForFilesGetWithFileId:child.identifier];
[self.driveService executeQuery:query                          completionHandler:^(GTLServiceTicket *ticket,
                             GTLDriveFile *file,
                             NSError *error) 
{
NSLog(@"\nfile name = %@", file.originalFilename);}];
                      }
                  }
              }];
 }

// Quero exibir todo o conteúdo no NSLog ...
