CSV上传（转换为电子表格）在谷歌驱动器在iOS？

我已经生成csv文件存储在本地目录path。 我试图上传CSV文件到谷歌驱动器，它工作正常。 从谷歌驱动器打开一个CSV文件，而不是在电子表格中显示预览。 所以我想上传CSV文件（转换CSV到电子表格）到谷歌驱动器。 如何转换？

上传csv文件以供您参考：

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES); NSString *documentsDir = [paths objectAtIndex:0]; NSString *root = [documentsDir stringByAppendingPathComponent:@"Report.csv"]; BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:root]; if(fileExists == YES) { GTLUploadParameters *uploadParameters = nil; self.driveFile = [[GTLDriveFile alloc]init]; NSData *dat = [NSData dataWithContentsOfURL:[NSURL fileURLWithPath:root]]; uploadParameters = [GTLUploadParameters uploadParametersWithData:dat MIMEType:@"text/csv"]; self.driveFile.title = @"Report.csv"; GTLQueryDrive *query = nil; if (self.driveFile.identifier == nil || self.driveFile.identifier.length == 0) { query = [GTLQueryDrive queryForFilesInsertWithObject:self.driveFile uploadParameters:uploadParameters]; } else { query = [GTLQueryDrive queryForFilesUpdateWithObject:self.driveFile fileId:self.driveFile.identifier uploadParameters:uploadParameters]; } UIAlertView *alert = [DrEditUtilities showLoadingMessageWithTitle:@"While data is uploading..." delegate:self]; [self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket, GTLDriveFile *updatedFile, NSError *error) { appDel.File_Id = updatedFile.identifier; [alert dismissWithClickedButtonIndex:0 animated:YES]; if (error == nil) { self.driveFile = updatedFile; UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Feel Fix" message:@"Successfully Uploaded" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok", nil]; [alert show]; } else { NSLog(@"An error occurred: %@", error); [DrEditUtilities showErrorMessageWithTitle:@"Unable to save file" message:[error description] delegate:self]; } }];

插入转换属性来解决这个问题

  GTLUploadParameters *uploadParameters = nil; self.driveFile = [[GTLDriveFile alloc]init]; NSData *dat = [NSData dataWithContentsOfURL:[NSURL fileURLWithPath:root]]; uploadParameters = [GTLUploadParameters uploadParametersWithData:dat MIMEType:@"text/csv"]; self.driveFile.title = @"Report.csv"; GTLQueryDrive *query = nil; if (self.driveFile.identifier == nil || self.driveFile.identifier.length == 0) { query = [GTLQueryDrive queryForFilesInsertWithObject:self.driveFile uploadParameters:uploadParameters]; query.convert = YES; // Convert file format to spread sheet } else { query = [GTLQueryDrive queryForFilesUpdateWithObject:self.driveFile fileId:self.driveFile.identifier uploadParameters:uploadParameters]; } UIAlertView *alert = [DrEditUtilities showLoadingMessageWithTitle:@"While data is uploading..." delegate:self]; [self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket, GTLDriveFile *updatedFile, NSError *error) { appDel.File_Id = updatedFile.identifier; [alert dismissWithClickedButtonIndex:0 animated:YES]; if (error == nil) { self.driveFile = updatedFile; UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Feel Fix" message:@"Successfully Uploaded" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok", nil]; [alert show]; } else { NSLog(@"An error occurred: %@", error); [DrEditUtilities showErrorMessageWithTitle:@"Unable to save file" message:[error description] delegate:self]; } }];
