In your app, you would now send this token to your server to save and use later on for sending notifications.

You can ignore that for now. Later, when you run on a real device, you should receive a token in the console output. Use a text editor to create a file called first. Paste in the following JSON text and save the file. Build and run the app again on the simulator, then background the app or lock the device. The app is not yet able to process push notifications while in the foreground.

If there is only one device running in the simulator, you can use booted instead of an identifier. Use your mouse to copy the identifier. You might need to widen the dialog box to see it fully. Open the Terminal app and change to the directory where you saved first.

The payload is a JSON dictionary that contains at least one item, aps , which is also a dictionary. You can add custom fields to the payload like this, and they will get delivered to your application. There are eight built-in keys you can add to the aps dictionary see the official Payload Key Reference for more information :.

Outside of these, you can add as much custom data as you want, as long as the payload does not exceed 4, bytes. In the first case, WenderCast will create the news item and open directly to the News tab. In AppDelegate. To test this, you need to edit the scheme of WenderCast. First, build and run to install the latest code on the simulator. Then, click the WenderCast scheme and select Edit Scheme… :.

Select Run from the sidebar, then in the Info tab select Wait for executable to be launched :. This option will make the debugger wait for the app to be launched for the first time after installing to attach to it. Tap the notification, and the app will open to news:. To handle the situation where your app is running when a push notification is received, add the following to AppDelegate :. This tries to extract the aps from the supplied userInfo object and, if successful, creates a new NewsItem from it.

Since iOS calls this method when the app is running, you need to change the scheme back to launching the app automatically to test it. In the Scheme editor, under Launch , select Automatically. Keep the app running in the foreground and on the News tab. Send another news push notification and watch as it appears in the feed:.

Actionable notifications let you add custom buttons to the notification itself. Your app can define actionable notifications when you register for notifications by using categories. Each category of notification can have a few preset custom actions. Once registered, your server can set the category of a push notification. The corresponding actions will be available to the user when received. This action will allow users to view the news article in the app if they choose to.

In registerForPushNotifications , insert the following just below the guard and above the call to getNotificationSettings :. Background the app and then send the following payload via the xcrun simctl utility:. To get it to display the news item, you need to do some more event handling in the delegate.

Back in AppDelegate. This is the callback you get when the app opens because of a custom action. Close the app again, then send another news notification with the following payload:. Send a few more and try opening the notification in different ways to see how it behaves. However, if you want to get a feel for how to send push notifications to a real device and try silent push, then you need to do some additional setup.

Download the PushNotifications utility. To install it, follow the instructions under How to install. Leave a Reply Cancel reply Your email address will not be published.
