IOS：如何使用Google驱动器sdk库将文件上传到特定的Google驱动器文件夹

问题描述

我将Google驱动器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驱动器的特定文件夹。

这里是用来上传文件的代码。但是，这一个上传文件到我的谷歌驱动器根文件夹。任何一个共享代码上传文件到谷歌驱动器的特定文件夹？。

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 $ b $ uploadParametersWithData：[NSData dataWithContentsOfFile：filePath] 
 MIMEType：@application / pdf]; 
 
 GTLQueryDrive * query = [GTLQueryDrive queryForFilesInsertWithObject：driveFile $ b $ uploadParameters：uploadParameters]; 
 
 [self.driveService executeQuery：query 
 completionHandler：^（GTLServiceTicket * ticket，
 GTLDriveFile * updatedFile，
 NSError * error）{
 if（错误==无）{
 NSLog（@\\\
\\\
file上传到谷歌驱动器\\< my_folder> foler）; 
} else {
 NSLog（@\\\
\\\
file uplod failed google drive \\< my_folder> foler）; 
} 
}]; 
 
  

解决方案

您需要设置父母您的 driveFile 引用的属性。

  GTLDriveParentReference * parentRef = [GTLDriveParentReference object]; 
 parentRef.identifier = folderIdentifier; //文件夹的标识符属性
 driveFile.parents = @ [parentRef]; 
  

I integrated Google drive sdk with my iOS app. But I do not know how to upload a file to Google drive specific folder.

Here the code am using to upload the file. But this one uploading the file to my google drive root folder. Any one share a code to upload a file to google drive specific folder?.

My Code:

-(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");
    }
}];
}

解决方案

You need to set the parents property of your driveFile reference.

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