问题 This is a part of my code. I want to use UNUserNotificationCenter and UNUserNotificationCenterDelegate to handle notification events. This code catches the notification event when the app is in a foreground state. But "didReceive" is not fired for a background state. func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool { UNUserNotificationCenter.current().delegate = self application

Could I be sending too many messages too quickly? 回答1: According to the GCM guide, all 5xx error codes should be treated

Facebook notifies Apple that my device should receive a notification as such. But how does Apple know which device/IP to push the message to? 回答1: It was too much for me to put in a comment so. From the documentation. Apple Push Notification service (APNs) propagates push notifications to devices having

问题 I am trying to build a notification method that would result in a notification appearing on the locked screen when a particular beacon is detected. My understanding is that I need to include .setVisibility(0) in the following code: public void showNotification(Beacon beacon) { Resources r = getResources(); int random = (int)System.currentTimeMillis(); Notification notification = new NotificationCompat.Builder(this) .setSmallIcon(android.R.drawable.ic_popup_reminder) .setContentTitle("Beacons
