如何在Google Driver IOS App內部將文件夾上傳和檢索到appDataFolder

Question

如何在Google雲端硬盤的appDataFolder上上傳文件夾，我正在嘗試以下代碼，但無法正常工作。 因此，任何伙伴可以幫我有關從IOS App上傳Google雲端硬盤中的文件夾的問題。

GTLServiceDrive *drive= [self driveService];
        GTLDriveFile *folder = [GTLDriveFile object];
        folder.mimeType = @"application/vnd.google-apps.folder";
        folder.parents = @[appDataFolder];
        GTLUploadParameters *uploadParameters = [GTLUploadParameters
                                                 uploadParametersWithData:data
                                                 MIMEType:@"application/vnd.google-apps.folder"];
        GTLQueryDrive *query = [GTLQueryDrive queryForFilesCreateWithObject:folder uploadParameters:uploadParameters];
        //query.q = [NSString stringWithFormat:@"appDataFolder"];
        [drive executeQuery:query completionHandler:^(GTLServiceTicket *ticket,
                                                      GTLDriveFile *updatedFile,
                                                      NSError *error) {
            if (error == nil) {

                                } else {

            }
        }];

您需要設置driveFile的Parents屬性

GTLDriveParentReference *parentRef = [GTLDriveParentReference object];
parentRef.identifier = folderIdentifier; // identifier property of the folder
driveFile.parents = @[ parentRef ];
