使用Google Drive SDK创建文件夹iOS

我正尝试使用适用于iOS的Google Drive SDK创建文件夹。从谷歌驱动器文档浏览：使用Google Drive SDK创建文件夹iOS

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

它说，创建一个文件夹，就像创建一个“文件”具有特殊的MIME类型。

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，我得到：

“NSInternalInconsistencyException”，理由是：“上传数据和文件句柄是相互排斥的”

这表明我应该使用预定义的一个GTLUploadParameters工厂方法：

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

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

但这些都不合适（或工作，因为我已经尝试过）。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:...

是这方面的工作 –

@rmaddy，你可以分享你的completionBlock？是否传递了相同的参数，例如一个'GTLDriveFile *'？ – tarabyte

@tarabyte什么完成块？ – rmaddy

这里还有一个更完整的变体：

+ (void)createFolderWithService:(GTLServiceDrive *)service 
        folderName:(NSString *)folderName 
         parentId:(NSString *)parentId 
       completionBlock:(void (^)(GTLServiceTicket *, GTLDriveFile *, NSError *))completionBlock { 
    GTLDriveFile *folderObj = [GTLDriveFile object]; 
    folderObj.title = folderName; 
    folderObj.mimeType = @"application/vnd.google-apps.folder"; 

    if (parentId.length && ![parentId isEqualToString:@"0"]) { 
    GTLDriveParentReference *parentRef = [GTLDriveParentReference object]; 
    parentRef.identifier = parentId; 
    folderObj.parents = [NSArray arrayWithObject:parentRef]; 
    } 

    GTLQueryDrive *query = [GTLQueryDrive queryForFilesInsertWithObject:folderObj uploadParameters:nil]; 
    [service executeQuery:query completionHandler:completionBlock]; 
}
