Swift UILocalNotification：显示通知时是否可以触发事件？

Question

So I know the didReceiveLocalNotification event is fired when a user selects an action on a Local Notification.

But, is an event fired prior to that when the notification is displayed as a banner or alert when the app is not active? And can that be accessed to do some background code?

I am looking for an answer in Swift if you can help.

Answer 1

No, local notifications do not and cannot awake the app when firing and the application is not active. The user must tap the notification, or perform a developer defined action on it before the app hears anything.

If you need your app to wake up, you need to use a remote notification with content available flag set.
