How to display push notification when app is active?

Question

Objective-C

Good afternoon, please tell me, is there a method for intercepting the incoming push and displaying it when the application is in the foreground?

Answer 1

The AppDelegate has such a method. In the same place, you check if the application is active, then display the push through your implementation, some kind of your view. Otherwise, if the application is minimized, the push will be displayed by itself

Answer 2

If the application is open and a push has come , it will not be possible to show a native alert. As Maxim said above, you need to make your own class and show it.

Answer 3

The method will be called on the delegate only if the application is in the foreground. If the method is not implemented or the handler is not called in a timely manner then the notification will not be presented. The application can choose to have the notification presented as a sound, badge, alert and/or in the notification list. This decision should be based on whether the information in the notification is otherwise visible to the user.
