(Objective-C) Google Sheets - Append Values to an Existing Spreadsheet
Appends values to an existing Google spreadsheet.
#import <CkoJsonObject.h>
#import <CkoHttp.h>
#import <CkoHttpResponse.h>
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// This example uses a previously obtained access token having permission for the
// Google Sheets scope.
// In this example, Get Google Sheets OAuth2 Access Token, the access
// token was saved to a JSON file. This example fetches the access token from the file..
CkoJsonObject *jsonToken = [[CkoJsonObject alloc] init];
BOOL success = [jsonToken LoadFile: @"qa_data/tokens/googleSheets.json"];
if ([jsonToken HasMember: @"access_token"] == NO) {
NSLog(@"%@",@"No access token found.");
return;
}
CkoHttp *http = [[CkoHttp alloc] init];
http.AuthToken = [jsonToken StringOf: @"access_token"];
// To append values to an existing spreadsheet, our HTTP request body will
// contain JSON in the format of a "ValueRange". For example, the spreadsheet we'll be
// adding to in this example looks like this:
// 
// The JSON ValueRange for the cells in the above spreadsheet is:
// {
// "range": "Sheet1!A1:B5",
// "majorDimension": "ROWS",
// "values": [
// [
// "Item",
// "Cost"
// ],
// [
// "Wheel",
// "$20.50"
// ],
// [
// "Door",
// "$15"
// ],
// [
// "Engine",
// "$100"
// ],
// [
// "Totals",
// "$135.50"
// ]
// ]
// }
// This example will append 6 cells (3 rows / 2 columns).
// We'll be appending the following:
//
// "Paint", "$100"
// "Brakes", "$100"
// "New Total", "$335.50"
//
// The range of cells we'll be appending is A1:B5
// Therefore, the ValueRange JSON we'll be sending in our POST body is:
// {
// "range": "Sheet1!A1:B5",
// "majorDimension": "ROWS",
// "values": [
// [
// "Paint",
// "$100"
// ],
// [
// "Brakes",
// "$100"
// ],
// [
// "New Total",
// "$335.50"
// ]
// ]
// }
