私のAppDelegateでは、Core Dataにフェッチ要求を行うメソッドを追加しました。通知を表示している場合もあります廃止予定のメソッドがいくつかあることを示します。私はいくつかの変更を実行しようとしました、しかし：私は私のアプリを殺すときに私のアプリがフォアグラウンドにあるときバックグラウンドフェッチ要求と通知がすべての状況で機能しない
は、バックグラウンドモードが
を動作しません、バックグラウンドモードでは動作しますが、通知はしないでください私は、バックグラウンドで私のアプリを実行すると
を示し、すべてがここ
私は毎回（毎分）を実行する方法：
func notification(){
let appDel: AppDelegate = UIApplication.shared.delegate as! AppDelegate
let context: NSManagedObjectContext = appDel.managedObjectContext
var messageNotif:String? = nil
do {
let request = NSFetchRequest<NSFetchRequestResult>(entityName: "Leads")
let predicate = NSPredicate(format: "statutSendLead=%@ OR statutSendSimulation=%@", "0", "0")
request.predicate = predicate
let results = try context.fetch(request)
if results.count > 0 {
if Reachability.isConnectedToNetwork() == false {
messageNotif = "Votre demande n'a pas été envoyée, merci de vous connecter à internet."
} else {
Reachability.checkUrl(urlString:Configuration.MyVariables.url, finished: { isSuccess in
if isSuccess == false {
messageNotif = "Notre service d'enregistrement des demandes est temporairement indisponible, un renvoi sera effectué ultérieurement."
}
})
}
*/
if (messageNotif != nil) {
let identifier = self.stringWithUUID()
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in
let content = UNMutableNotificationContent()
content.body = messageNotif!
content.sound = UNNotificationSound.default()
// Deliver the notification in five seconds.
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false)
let request = UNNotificationRequest.init(identifier: "test", content: content, trigger: trigger)
// Schedule the notification.
let center = UNUserNotificationCenter.current()
UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
UNUserNotificationCenter.current().add(request) {(error) in
if let error = error {
print(error)
}
}
}
} else {
let notification = UILocalNotification()
notification.alertBody = messageNotif
notification.fireDate = NSDate() as Date
notification.soundName = UILocalNotificationDefaultSoundName
UIApplication.shared.scheduleLocalNotification(notification)
}
}
}
/* else {
timerNotification.invalidate()
} */
} catch {
print(error)
}
}
他の方法：
var window: UIWindow?
var timerUploadData:Timer!
var timerNotification:Timer!
var test:Timer!
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.setMinimumBackgroundFetchInterval(
UIApplicationBackgroundFetchIntervalMinimum)
let userDefaults = UserDefaults.standard
if userDefaults.object(forKey: "ApplicationUniqueIdentifier") == nil {
let UUID = Foundation.UUID().uuidString
userDefaults.set(UUID, forKey: "ApplicationUniqueIdentifier")
userDefaults.synchronize()
}
Thread.sleep(forTimeInterval: 3.0)
window = UIWindow(frame: UIScreen.main.bounds)
let containerViewController = ContainerViewController()
window!.rootViewController = containerViewController
window!.makeKeyAndVisible()
if #available(iOS 10.0, *){
application.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
timerNotification = Timer.scheduledTimer(timeInterval: 60 * 1, target: self, selector: #selector(AppDelegate.notification), userInfo: nil, repeats: true)
}
else { //If user is not on iOS 10 use the old methods we've been using
let notificationSettings = UIUserNotificationSettings(
types: [UIUserNotificationType.badge, UIUserNotificationType.alert, UIUserNotificationType.sound], categories: nil)
timerNotification = Timer.scheduledTimer(timeInterval: 60 * 1, target: self, selector: "notification", userInfo: nil, repeats: true)
application.registerUserNotificationSettings(notificationSettings)
}
registerPushNotifications()
return true
}
func application(_ application: UIApplication, performFetchWithCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
notification()
}
func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
if notificationSettings.types != UIUserNotificationType() {
application.registerForRemoteNotifications()
}
}
func registerPushNotifications() {
DispatchQueue.main.async {
let settings = UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil)
UIApplication.shared.registerUserNotificationSettings(settings)
}
}
func stringWithUUID() -> String {
let uuidObj = CFUUIDCreate(nil)
let uuidString = CFUUIDCreateString(nil, uuidObj)!
return uuidString as String
}
