使用Google Drive SDK iOS创建文件夹

Question

我正在尝试使用Google Drive SDK for iOS创建一个文件夹.从Google Drive文档中:

https://developers.google.com/drive/folder

它说创建文件夹就像创建一个具有特殊MIME类型的"文件"一样.

GTLUploadParameters *uploadParameters = nil;

self.driveFile = [GTLDriveFile object];
self.driveFile.title = foldername;

uploadParameters = [GTLUploadParameters new];
uploadParameters.MIMEType = @"application/vnd.google-apps.folder";

GTLQueryDrive *query = nil;
query = [GTLQueryDrive queryForFilesInsertWithObject:self.driveFile
                                    uploadParameters:uploadParameters];


[self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,
                                                          GTLDriveFile *updatedFile,
                                                          NSError *error) {

但是当我执行查询时,我得到:

'NSInternalInconsistencyException',原因:'upload data和fileHandle是互斥的'

这表明我应该使用预定义的GTLUploadParameters工厂方法之一:

+ (GTLUploadParameters *)uploadParametersWithData:(NSData *)data
                                         MIMEType:(NSString *)mimeType;

+ (GTLUploadParameters *)uploadParametersWithFileHandle:(NSFileHandle *)fileHandle
                                               MIMEType:(NSString *)mimeType;

但这些都不合适(或正如我所尝试的那样工作).有没有人在iOS上使用Google云端硬盘成功创建文件夹？

我这样做:

    GTLDriveFile *folderObj = [GTLDriveFile object];
    folderObj.title = folderName;
    folderObj.mimeType = @"application/vnd.google-apps.folder";

    // To create a folder in a specific parent folder, specify the identifier
    // of the parent:
    // _resourceId is the identifier from the parent folder
    if (_resourceId.length && ![_resourceId isEqualToString:@"0"]) {
        GTLDriveParentReference *parentRef = [GTLDriveParentReference object];
        parentRef.identifier = _resourceId;
        folderObj.parents = [NSArray arrayWithObject:parentRef];
    }

    GTLQueryDrive *query = [GTLQueryDrive queryForFilesInsertWithObject:folderObj uploadParameters:nil];

    // executeQuery:...
