Introduction

Local notifications are short, text-based messages that appear at the top of your iPhone’s screen.

On iOS, you can send and receive two types of notifications:

• Push Notifications: Push notifications are sent via the internet, such as chat messages. They’re relayed to your iPhone via the web-based Apple Push Notification Service (APNS).
• Local Notifications: Local notifications are scheduled and “sent” locally on your iPhone, so they aren’t sent over the internet. Typical use cases are calendar reminders or the iPhone alarm clock.

Local notifications are ideal for “local” functionality, such as reminding a user about an upcoming calendar event, a pending to-do list item, or an inspiring quote from your favorite wellness app.

In this article i will share about this Local Notification and how to create it.

Let say i’ll make schedule for muslim prayer time. I need to create schedule model data first.

After this model data created, it will be easy to passing into Local Notification Creation.

Parsing from Model Data into Create Local Notification

This function can be called from you view controller to send JadwalModel data to registered as scheduled Local Notification.

Remove Local Notification

This function is to remove all your Local Notification.
