IOS:如何使用 Google Drive SDK 库将文件上传到特定的 Google Drive 文件夹

Question

我将 Google Drive SDK 与我的 iOS 应用程序集成在一起。但我不知道如何将文件上传到 Google 驱动器特定文件夹。

此处的代码用于上传文件。但是这个将文件上传到我的谷歌驱动器根文件夹。任何人共享代码以将文件上传到谷歌驱动器特定文件夹？

我的代码:

-(void)uploadFileToGoogleDrive:(NSString*)fileName
{    
GTLDriveFile *driveFile = [[[GTLDriveFile alloc]init] autorelease];

driveFile.mimeType = @"application/pdf";
driveFile.originalFilename = @"test.doc";
driveFile.title = @"test.doc";

NSString *filePath = [LocalFilesDetails getUserDocumentFullPathForFileName:fileName isSignedDocument:YES];

GTLUploadParameters *uploadParameters = [GTLUploadParameters
                                         uploadParametersWithData:[NSData dataWithContentsOfFile:filePath]
                                         MIMEType:@"application/pdf"];    

GTLQueryDrive *query = [GTLQueryDrive queryForFilesInsertWithObject:driveFile
                                    uploadParameters:uploadParameters];

[self.driveService executeQuery:query 
  completionHandler:^(GTLServiceTicket *ticket,
                       GTLDriveFile *updatedFile,
                       NSError *error) {
    if (error == nil) {
        NSLog(@"\n\nfile uploaded into google drive\\<my_folder> foler");
    } else {
        NSLog(@"\n\nfile uplod failed google drive\\<my_folder> foler");            
    }
}];
}

您需要设置driveFile 引用的parents 属性。

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