Question

我正在尝试在iOS中制作谷歌驱动器文件管理应用程序。我被困了，因为我想使用任何关键字搜索所有文件，它应该是显示文件和文件夹。使用此代码获取所有文件和文件夹。但是如果搜索某些内容，则只搜索当前文件。你能建议我如何获得子文件和文件夹，因为它只显示单一级别而不显示其他文件 - （无效）getGDriveFilesAndFolders {

GTLQueryDrive *query = [GTLQueryDrive queryForFilesList];
if ([self.strPath length] == 0)
{
    query.q = @"'root' in parents";
}else{
    NSString *queryString = [NSString stringWithFormat:@"'%@' in parents",self.strPath];
    query.q=queryString;
}

[GoogleDriveViewController.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,GTLDriveFileList *files,NSError *error)
 {
     if (error == nil)
     {
         [marrFiles removeAllObjects];

         NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init];
         [dateFormatter setDateFormat:@"yyyy-MM-dd hh:mm:ss"];

         for(int i = 0; i < [files items].count; i++)
         {
             GTLDriveFile *driveFile = (GTLDriveFile*)[files itemAtIndex:i];
             if([driveFile.mimeType isEqualToString:@"application/vnd.google-apps.folder"])
             {
                 if([driveFile.explicitlyTrashed intValue]!=1)
                 {
                     NSString *fileName = driveFile.title;
                     NSMutableDictionary *dict = [NSMutableDictionary dictionary];
                     [dict setValue:fileName forKey:[NSString stringWithFormat:@"Folder"]];
                     [dict setValue:driveFile.identifier forKey:@"objectId"];
                     [marrFiles addObject:dict];
                 }
             }
             else{
                 if([driveFile.explicitlyTrashed intValue] != 1)
                 {
                     NSString *fileName = driveFile.title;
                     NSMutableDictionary *dict = [NSMutableDictionary dictionary];
                     [dict setValue:fileName forKey:[NSString stringWithFormat:@"File"]];
                     long long int sizeData = [driveFile.fileSize intValue];
                     NSString *stringSize = [FileSizeClass stringSizeForFileWithBytes:[NSNumber numberWithLongLong:sizeData]];
                     GTLDateTime *modificationDate = (GTLDateTime*)driveFile.modifiedDate;
                     NSDate *date = [modificationDate date];
                     NSString *dateString = [dateFormatter stringFromDate:date];
                     dateString = [dateString createdTimeString];
                     NSString *stringInfo = [NSString stringWithFormat:@"%@ %@",stringSize,dateString];
                     [dict setValue:stringInfo forKey:[NSString stringWithFormat:@"Size"]];
                     [dict setValue:driveFile.identifier forKey:@"objectId"];
                     [dict setValue:driveFile.downloadUrl forKey:@"downloadUrl"];
                     [dict setValue:driveFile.fileSize forKey:@"FileSize"];

                     if(driveFile.webContentLink)
                     {
                         [dict setValue:driveFile.webContentLink forKey:@"webContentLink"];
                     }
                     [marrFiles addObject:dict];
                 }
             }
         }
         [tblGoogleDrive reloadData];
     } else {
         UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:NSLocalizedString(@"Message",nil) message:[error localizedDescription] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
         [alertView show];
     }
     [MBProgressHUD hideAllHUDsForView:self.view animated:YES];
 }];

}

使用'folder id' in parents之类的搜索查询只会搜索该文件夹的直接子项，而不会搜索子文件夹中的子项。搜索子文件夹没有内置方法，但您可以创建一个复合查询，您可以在其中明确搜索每个子文件夹，例如'folder' in parents or 'sub-folder1' in parents ...
