核心数据和用户默认值不存储数据

Question

Core Data and UserDefaults not storing data when my application is closed.

I am getting notification when my application is closed so i store it in core data and defaults to do some stuff.

when the application is open it is storing all informations but only application is closed its not working, any idea to do it.

I stored my data in the following function.

  func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
            let response = notification.request.content.userInfo["aps"] as! NSDictionary
             //here i will send response will store to core date
            self.defaults.set("1", forKey: "notifyid")
            completionHandler([.alert, .badge, .sound])
        }
    } 

Answer 1

You are storing it in wrong function. Will Present only gets called when the app is in Foreground. so it will not work when app is in background, Instead of Will Present function use did receive remote function:

func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) {
    let response = notification.request.content.userInfo["aps"] as! NSDictionary
    self.defaults.set("1", forKey: "notifyid")    
}

Note: Please make sure in your app capabilities under Background Modes your remote notification and background fetch. Otherwise it won't work.
