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]

GTLQueryDrive *query = [GTLQueryDrive queryForFilesInsertWithObject:driveFile

[self.driveService executeQuery:query 
  completionHandler:^(GTLServiceTicket *ticket,
                       GTLDriveFile *updatedFile,
                       NSError *error) {
    if (error == nil) {
        NSLog(@"

file uploaded into google drive\<my_folder> foler");
    } else {
        NSLog(@"

file uplod failed google drive\<my_folder> foler");            
    }
}];
}

推荐答案

您需要设置 driveFile 引用的 parents 属性.

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 ];
