Local Notification in Swift

A ‘local notification’ is a short text-based message which appears on the top of the screen. It lets users know that there is some information for them.

one can send and receive notification from two type

1. Push Notification
2. Local Notification

‘Push Notification’ => It is sent through the internet

‘Local Notification’ =>It is the schedule and sends locally in the iPhone

In this blog, we will learn about the local Notification. Before our application can send any notifications,  we must fulfill the request for sending notifications so that the user can approve or reject it.

For successfully sending the local Notification we have to follow the following steps:-

Steps 1=> First We have to import UserNotifications in Appdelegates, and then we have to create a new 'notificationCenter' property and have to assign an instance of the ‘UNUserNotificationCenter' class to it to manage notifications. This will be our notification center.

For more information about ‘UNUserNotificationCenter’ you can check apple developer link https://developer.apple.com/documentation/usernotifications/unusernotificationcenter

 

Steps 2=> In the ‘didFinishLaunchingWithOptions‘ methods we will declare option for our notification, we will use the ‘badge‘, ‘sound‘, and ‘alert‘

 

Before sending the notification we have to ask permission from the user

It will look like this when app launch

 

Step 3= > Now to trigger the ‘Notification’ we will create a method and call it when we like to call, like on any button click

 

We have set the time interval of 4 seconds. So, after 4 seconds the notification will show when the apps in the background
