How to Create events using Google Calendar API iOS Swift

Question

I want to develop one demo app which will create events using my Application, store it using Google Calendar API and then fetch all the data and gives reminder. I have referred this link to fetch data and for setup, but I am not getting how to create events. Can anyone guide me how can I do this? I searched a lot for creating events using iOS, but I don't get anything useful for Google Calendar API, I found all the stuff using EventKit framework.

Please help me. Thank You.

No.. I am able to fetch data using this link. but I want to create events from my app. I don't know how to do that — Riddhi Shah
Actually, until you can't tell where you were going wrong nobody can help. It's google developer form what you following and mostly there is no sign of issues in their forms. so cross check your steps with the available steps on the google form that you provided as a link! — Himanshu
I have no issues with that code. That code is used for fetching events from google Calendar API and it works perfectly. I am asking that I want to create and register events using my iOS Application. — Riddhi Shah

I've found a tutorial: "iOS SDK: Working with Google Calendars", in this tutorial they provide insights on downloading the calendars, and creating a new event with a description and a date/time.

Regarding our app structure, the basic view is going to be a table view that will contain three sections for setting the following data:

An event description

An event date/time

A target calendar

A code example for adding event(Objective C):

// Create the URL string of API needed to quick-add the event into the Google calendar.
// Note that we specify the id of the selected calendar.
NSString *apiURLString = [NSString stringWithFormat:@"https://www.googleapis.com/calendar/v3/calendars/%@/events/quickAdd",
                          [_dictCurrentCalendar objectForKey:@"id"]];

// Build the event text string, composed by the event description and the date (and time) that should happen.
// Break the selected date into its components.
NSDateComponents *dateComponents = [[NSDateComponents alloc] init];
dateComponents = [[NSCalendar currentCalendar] components:NSDayCalendarUnit|NSMonthCalendarUnit|NSYearCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit
                                                 fromDate:_dtEvent];

if (_isFullDayEvent) {
    // If a full-day event was selected (meaning without specific time), then add at the end of the string just the date.
    _strEventTextToPost = [NSString stringWithFormat:@"%@ %d/%d/%d", _strEvent, [dateComponents month], [dateComponents day], [dateComponents year]];
}
else{
    // Otherwise, append both the date and the time that the event should happen.
    _strEventTextToPost = [NSString stringWithFormat:@"%@ %d/%d/%d at %d.%d", _strEvent, [dateComponents month], [dateComponents day], [dateComponents year], [dateComponents hour], [dateComponents minute]];
}

// Show the activity indicator view.
[self showOrHideActivityIndicatorView];

// Call the API and post the event on the selected Google calendar.
// Visit https://developers.google.com/google-apps/calendar/v3/reference/events/quickAdd for more information about the quick-add event API call.
[_googleOAuth callAPI:apiURLString
       withHttpMethod:httpMethod_POST
   postParameterNames:[NSArray arrayWithObjects:@"calendarId", @"text", nil]
  postParameterValues:[NSArray arrayWithObjects:[_dictCurrentCalendar objectForKey:@"id"], _strEventTextToPost, nil]];

I think you can implement this from what you have started in the iOS Quickstart Google.

I hope this helps. Goodluck :)
