收到远程通知时是否有应答代理的回调？

收到远程通知并且用户采取行动（关闭/解除除外）后，应用程序委托获得回调：

  • （void）application：（UIApplication *）application didReceiveRemoteNotification：（NSDictionary *）userInfo fetchCompletionHandler：（void（^）（UIBackgroundFetchResult））completionHandler

或者如果应用程序已注册通知操作：

  • （void）application：（UIApplication *）application handleActionWithIdentifier：（NSString *）identifier forRemoteNotification：（NSDictionary *）userInfo completionHandler：（void（^）（））completionHandler

我的问题是，当收到远程通知时，应用程序是否收到回调？那是在用户采取任何行动之前 . 感谢您的输入 .

    不，该应用程序未获得通知已到达设备的任何迹象 . 如您在问题中的两个案例中所描述的那样，只有在通知实际发送到应用程序时才会收到委托调用 .

    是的，当然，当收到远程通知时，app会收到以下代理方法的回调 .

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    print("DEVICE TOKEN = \(deviceToken)")
}
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    print(error)
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    print(userInfo)
}

    extension AppDelegate: UNUserNotificationCenterDelegate {

    public func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        completionHandler([.alert,.sound,.badge])
        print("NOtification received")
    }

    public func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    print("original body was : \(response.notification.request.content.title)")
    print("Tapped in notification")

    }
}
