How Can a Web Application Send Push Notifications to iOS Devices

How can a web application send push notifications to iOS devices?

To be more specific, in order for a web application to send push notifications to a mobile device, such as the iPhone, the mobile device must have registered to receive push notifications for a particular application. The registration for push notification is done through a native app and can only be performed through a native app. Once the native app is registered for push notification, it can send the authorization token to the server, which can be used in conjunction with the certificate used to provision the native client, to send the push notifications to the mobile device.

As specified in another answer, one option is to 'wrap' your web application in a native application. Meaning that you would create a native application that basically presents a UIWebView (for iPhone dev) to the user showing your web application. While this pretty much functions in the same manner as the native browser, you would be able to add the ability to register for push notifications using the native controls.

It would be beneficial to you to review the Apple's push notification document as it provides some pretty good information on how push messaging functions on the iPhone.

Is there a way to send Push Notification to an iPhone from my website?

It is possible for Websites to send Web Push notifications to Chrome (and soon Firefox) users on Android, however it is not possible to do this on iOS devices.

Apple has not currently indicated whether they plan to add support for this, but there's a good chance they will add it eventually.

Here is a blog post I wrote a few months ago that discusses this limitation: https://onesignal.com/blog/when-will-web-push-be-supported-in-ios/

Push notifications on iOS from web-app

As of today a web app cannot receive push notifications on any iOS browser (Safari, Chrome for iOS, ...). The reason is that iOS does not yet include an implementation of Service Workers, which are needed for push notifications to work.
It is currently in development, though: https://webkit.org/status/#specification-service-workers

And it is already working on Safari for OS X: https://developer.apple.com/notifications/safari-push-notifications/

Meanwhile, you will have to settle for a native implementation of your app, at least on iOS. My recommendation would be using what you have developed for web and making it a hybrid app through the use of Apache Cordova.

You can also regularly check if support is available here:
