使用Google Drive SDK iOS创建文件夹 [英] Create folder with Google Drive SDK iOS

问题描述

我正在尝试使用Google Drive SDK for iOS创建一个文件夹。在此处的Google云端硬盘文档中：

I'm trying to create a folder using the Google Drive SDK for iOS. From the Google Drive documentation here:

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

它表示创建文件夹就像创建具有特殊MIME类型的文件一样。

It says that creating a folder is just like creating a 'file' with a special MIME type.

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：

But when I perform the query, I get:

'NSInternalInconsistencyException '，原因：'上传数据和fileHandle是互斥的'

'NSInternalInconsistencyException', reason: 'upload data and fileHandle are mutually exclusive'

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

This suggests I should be using one of the predefined GTLUploadParameters factory methods:

+ (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？

But neither of these are appropriate (or work, as I've tried). Has anyone successfully created folders using Google Drive on iOS?

推荐答案

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:...
