是否确保UNNotificationServiceExtension调用可变内容= 1的每个通知

Question

I understand that with silent notifications, there is a possibility of make n/w connections when app is in background. iOS may not always call didReceiveNotification depending on various conditions like connected to power etc.

I notice with iOS 10 we have UNNotificationServiceExtension which gets called before notification is delivered to user. In this extension we can actually make n/w connections in bg.

• If not, then what is the point of UNNotificationServiceExtension ?

Answer 1

what is the point of UNNotificationServiceExtension

For one thing — quite a big thing — it is to allow you to customize the interface that the user sees when force-touch-pressing / long-pressing the notification alert.
