Titanium.Calendar

The Calendar module provides an API for accessing the native calendar functionality.

This module supports retrieving information about existing events and creating new events. Modifying or deleting existing events and creating recurring events are only supported on iOS.

Android

On Android, calendar permissions must be explicitly configured in tiapp.xml in order to access the calendar and you have to use requestCalendarPermissions to request runtime permissions.

<uses-permission android:name="android.permission.READ_CALENDAR"/>
<uses-permission android:name="android.permission.WRITE_CALENDAR"/>

See "Common Requirements" in tiapp.xml and timodule.xml Reference.

Extends: Titanium.Module · Since: 3.2.0, 3.1.0, 3.1.0 · Platforms: android, iphone, ipad, macos

Methods #

addEventListener #

extended

Adds the specified callback as an event listener for the named event.

Parameters:
NameTypeSummaryOptional
nameStringName of the event.No
callbackCallback<Titanium.Event>Callback function to invoke when the event is fired.No

applyProperties #

extended

Applies the properties to the proxy.

Properties are supplied as a dictionary. Each key-value pair in the object is applied to the proxy such that
myproxy[key] = value.

Parameters:
NameTypeSummaryOptional
propsDictionaryA dictionary of properties to apply.No

fireEvent #

extended

Fires a synthesized event to any registered listeners.

Parameters:
NameTypeSummaryOptional
nameStringName of the event.No
eventDictionaryA dictionary of keys and values to add to the Titanium.Event object sent to the listeners.Yes

getCalendarById #

Gets the calendar with the specified identifier.

Parameters:
NameTypeSummaryOptional
idStringIdentifier of the calendar.No

Returns: Titanium.Calendar.Calendar

hasCalendarPermissions #

Returns true if the app has calendar access.

Returns: Boolean

removeEventListener #

extended

Removes the specified callback as an event listener for the named event.

Multiple listeners can be registered for the same event, so the
callback parameter is used to determine which listener to remove.

When adding a listener, you must save a reference to the callback function
in order to remove the listener later:

var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);

To remove the listener, pass in a reference to the callback function:

window.removeEventListener('click', listener);
Parameters:
NameTypeSummaryOptional
nameStringName of the event.No
callbackCallback<Titanium.Event>Callback function to remove. Must be the same function passed to addEventListener.No

requestCalendarPermissions #

Requests for calendar access.

On Android, the request view will show if the permission is not accepted by the user, and the user did
not check the box "Never ask again" when denying the request. If the user checks the box "Never ask again,"
the user has to manually enable the permission in device settings. This method requests Manifest.permission.READ_CALENDAR
and Manifest.permission.WRITE_CALENDAR on Android. If you require other permissions, you can also use
Titanium.Android.requestPermissions.

In iOS 6, Apple introduced the Info.plist key NSCalendarsUsageDescription that is used to display an
own description while authorizing calendar permissions. In iOS 10, this key is mandatory and the application
will crash if your app does not include the key. Check the Apple docs for more information.

Parameters:
NameTypeSummaryOptional
callbackCallback<EventsAuthorizationResponse>Function to call upon user decision to grant calendar access.
Optional on SDK 10, as this method will return a Promise, which may be used to handle the result.
Yes

Returns: Promise<EventsAuthorizationResponse> — On SDK 10+, this method will return a `Promise` whose resolved value is equivalent to that passed to the optional callback argument.

Events #

change #

Fired when the database backing the EventKit module is modified.

This event is fired when changes are made to the Calendar database, including adding,
removing, and changing events or reminders. Individual changes are not described.
When you receive this notification, you should refetch all Event objects you have
accessed, as they are considered stale. If you are actively editing an event and
do not wish to refetch it unless it is absolutely necessary to do so, you can call
the refresh method on it. If the method returns
YES, you do not need to refetch the event.

Examples #

All Calendars vs Selectable Calendars

Print the names of all calendars, and the names of calendars that have been selected in the native Android calendar application.

function showCalendars(calendars) {
    for (var i = 0; i < calendars.length; i++) {
        Ti.API.info(calendars[i].name);
    }
}
// Provide permissions if necessary
if (!Ti.Calendar.hasCalendarPermissions()) {
    Ti.Calendar.requestCalendarPermissions(function (e) {
        if (e.success) {
            printCalendars();
        }
    });
} else {
    printCalendars();
}

function printCalendars() {
    Ti.API.info('ALL CALENDARS:');
    showCalendars(Ti.Calendar.allCalendars);
    if (Ti.Platform.osname === 'android') {
        Ti.API.info('SELECTABLE CALENDARS:');
        showCalendars(Ti.Calendar.selectableCalendars);
    }
}

Create an Event and Reminder on Android

Creates an event and adds an e-mail reminder for 10 minutes before the event.

var CALENDAR_TO_USE = 3;
var calendar = Ti.Calendar.getCalendarById(CALENDAR_TO_USE);

// Create the event
var eventBegins = new Date(2010, 11, 26, 12, 0, 0);
var eventEnds = new Date(2010, 11, 26, 14, 0, 0);
var details = {
    title: 'Do some stuff',
    description: "I'm going to do some stuff at this time.",
    begin: eventBegins,
    end: eventEnds
};

var event = calendar.createEvent(details);

// Now add a reminder via e-mail for 10 minutes before the event.
var reminderDetails = {
    minutes: 10,
    method: Ti.Calendar.METHOD_EMAIL
};

event.createReminder(reminderDetails);
