2 way syncing from iOS calendar event to our app - ios

How we can do 2 way syncing of calendar events in iOS from our application.
For example say ToDo is my app
I create an event in ToDo; it's automatically created into calendar app using event kit.
I delete an event in ToDo it's automatically deleted form calendar app
Question:
If I create an event into calendar can it be created into ToDo also???
If I delete a ToDo event form calendar can it be deleted form ToDo app too???
So basically I need two way syncing of events between my app and the iOS native calendar app

Yes this can be done if you use the Event kit.
Refer the sample code in this link

Calendar integration and sync-ing (Swift)

I have an app with a calendar integration that I am working on, but once it adds to the calendar then any changes only create a new calendar entry. How can I get these to stay connected so any changes in the app are updated to the calendar?

Firebase custom event for ios "notification_open" not showing on dashboard

I know that notification_open is used by Firebase on Android but not on ios.
Can I use notification_open as a custom event name on iOS app?
You shouldn't use preserved event names in Automatically collected events, after I change to something like ios_notification_open, it shows up in Firebase Analytics dashboard

iOS: Open a Calendar app New Event screen with populated date

Is it possible to redirect a user to Calendar app New Event screen programmatically with populated start and end dates? I am aware of Introduction to Calendars and Reminders, but that seems to be an overkill. I have also tried calshow://, but didn't seem to work either or I am couldn't find a correct scheme.

iOS: Create calendar with uneditable events?

From an app, is there a way to programmatically create a calendar with events that are uneditable? Or, what is the best way to achieve this as close as possible?
For example, Facebook events have a unique "Event Details" screen with their custom details. The user cannot edit the event from iCal, but instead have to click "View on Facebook".
1) I've explored creating local calendars and iCloud calendars but the user can easily edit the events and the calendars, including removing them, from iCal.
2) From the app, I cannot seem to create a new EKSource to have total control of the calendars I create in that source. Creating a new calendar in the existing CalDAV source also doesn't make it appear.
3) The EKCalendar class has an allowsContentModifications property, but it is readonly and cannot be modified.
Official response from Apple Developer Technical Support:
Our engineers have reviewed your request and have concluded that there
is no supported way to achieve the desired functionality given the
currently shipping system configurations.
So as of right now there isn't a way to do this.

Google Sync the calendar on iOS

I am quite new to iOS, and I would appreciate if you can give me a clue on how to tackle this issue.
I am planning a mobile application and a cloud service to require "Google calendar is sync with the calendars on mobile devices" ( namely iPhone, iPad, and Android )
On Android, I can read calendar's event id from our Android app. If I change event attributes such as tile and time etc, the event id stays unchanged, and it seems to be a good way to associate our meta data to it (i.e. event id).
On iOS side, if I enable Google Sync, the events I defined on web still appear on the calendar on iOS. My question is "Can I problematically get event id that are assigned on Google Calendar?"
The following link says
"EKEvent's eventIdentifier is likely to be changed when event changes"
http://developer.apple.com/library/ios/#documentation/EventKit/Reference/EKEventClassRef/Reference/Reference.html#//apple_ref/occ/instm/EKEvent/eventIdentifier
... so my guess is that this field does not reflect event id from Google calendar.
I appreciate any suggestions.
Usually the event identifier is of the form:
88E45678-2S11-574E-ABF8-3B1E463ERF4C:google_calendar_id#google.com
for a google sync calendar event.
If there was a change made to one of the recurring calendar events the identifier can also have exception date at the end:
88E45678-2S11-574E-ABF8-3B1E463ERF4C:google_calendar_id#google.com<!ExceptionDate>20121025
