How to fetch device google calendar events in custom iOS App?

Question

I am developing an app to fetch the device google calendar events in my custom iOS App. I have read the documentation about Event Kit on how to create and edit an edit but i am not able to fetch the google calendar events in my App. Is there any tutorial on how to fetch the google calendar events from the device? I need to fetch the google event ID into my app. Can someone please guide on how to achieve this?

This answer may be too delayed one. Hope this will help in future.

To fetch events from native calendar db,

EKEventStore *eventStore = [[EKEventStore alloc] init];

NSPredicate *fetchCalendarEvents = [eventStore predicateForEventsWithStartDate:startDate endDate:endDate calendars:nil];
//Use any specific calendar if you can provide detail. To get calendar detail, use the below code.

NSArray *eventListforDay = [NSArray arrayWithArray:[eventStore eventsMatchingPredicate:fetchCalendarEvents]];

To select calendar from available system / cloud calendars

NSArray *cals = [NSArray arrayWithArray:[eventStore calendarsForEntityType:EKEntityTypeEvent]];

for(EKCalendar *iCal in cals) {
    if (iCal.source.sourceType == EKSourceTypeCalDAV && [iCal.source.title isEqualToString:YOUR_CALENDAR_TITLE]) {
        //save calendar identifier for future use.
        break;
    }
}
