Description

NotificationManager is the class that allows you to manage scheduled and received notifications. This is a class with a single instance which can be retrieved using getSharedInstance() and can not have any new instances.

With NotificationManager you can retrieve information about all scheduled local notifications, all received local notifications and all received push notifications. As well as clear all type of notifications and cancel scheduled notifications.

NotificationManager instance also receives events about notification being clicked and app opened through that specific notification. As well as registration for push notification event or registration error.

Examples

Modifying existing scheduled notification

--id of notification to modify
local id = 1

--retrieve shared instance
local mngr = NotificationManager.getSharedInstance()

--retrieve table with scheduled notifications
local t = mngr:getScheduledNotifications()

--check if id is in it
if t[id] then
	--notification is still scheduled
	--let's modify it by creating new instance with same id
	local note = Notification.new(id)
	note:setTitle("New title")
	note:setMessage("New message")
	--if we want to modify dispatch time we need to redispatch it
	note:dispatchAfter({day = 1})
end

Checking if notification is stil scheduled

--id of notification to check
local id = 1

--retrieve shared instance
local mngr = NotificationManager.getSharedInstance()

--retrieve table with scheduled notifications
local t = mngr:getScheduledNotifications()

--check if id is in it
if t[id] then
	--notification is still scheduled
end

Catching event if app opened from local notification or notification received in background

--retrieve shared instance
local mngr = NotificationManager.getSharedInstance()

mngr:addEventListener(Event.LOCAL_NOTIFICATION, function(e)
	--getting id of notification
	local id = e.id
	
	--printing other information
	print("Title: "..e.title)
	print("Text: "..e.message)
	print("Number: "..e.number)
end)

Registering for push notifications

--retrieve shared instance
local mngr = NotificationManager.getSharedInstance()

--if registration completed succesfully
mngr:addEventListener(Event.PUSH_REGISTRATION, function(e)
	--getting device token
	local token = e.deviceToken
	
	--sending token to your server
	local loader = UrlLoader.new("http://yourdomain.com/register.php?token="..token)
	loader:addEventListener(Event.COMPLETE, function()
		--token succesfuly deliverd
	end)
end)

--if registration failed
mngr:addEventListener(Event.PUSH_REGISTRATION_ERROR, function(e)
