how to send notification if the user is connected my open wifi network in iPhone

Question

I want to send a prompt (notification) to an iPhone device which is connected to my open wifi network?

What is the correct approach to achieve this?

Answer 1

You will need an APN server, and push those notifications through Apple's notification gateways.

You can make your own or use a SaaS like urban airship .

Alternatively, make a server on your computer and connect to it from the iPhone. Use websockets, when an event happens on the server make a local notification on the iPhone.

Local notifications are allowed on iOS but you might have trouble keeping the websocket connection to your server when the app is in the background.
