What would be life cycle of app? when app is in terminated state and push kit payload comes.
First of all Pushkit delegate methods will work or AppDelegate methods will
Once push kit payload reaches to iOS device. Whole iOS app becomes active in background ( Take a note - Application would not invoke or come in foreground ) , just app will become active in background.
First of all
didFinishLaunchingWithOptions // will invoke
then
didReceiveIncomingPushWithPayload // payload method gets invoke
then if you have local notification
didReceiveLocalNotification // receive local notification
then
handleActionWithIdentifier // handler method if you have action buttons ( local )
then if you have remote notification
didReceiveRemoteNotification // receive remote notification
then
handleActionWithIdentifier // handler method if you have action buttons ( remote )
Pushkit mostly beneficial in VOIP related apps, when silent push notification comes and work accordingly.
When mostly required to remove 1 particular notification when particular notification comes. using pushkit we can schedule local notifications and while getting another push kit notification we can remove 1st local notification without end users interaction. otherwise app would not be able to remove notification without user's interaction.
