UNUserNotificationがiosで瞬時に通知を送信しています

Question

アプリケーションをバックグラウンドに入力した後、60秒ごとに通知を送信します。しかし、背景を入力するとすぐに通知が送信され、その後60秒ごとに通知が送信されます。私はすぐに通知を送信したくない、どうすればいい？ここで

が私のコードで、

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
    // Override point for customization after application launch. 
    let center = UNUserNotificationCenter.current() 
    center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in 
     // Enable or disable features based on authorization. 
    } 
    return true 
} 

func applicationDidEnterBackground(_ application: UIApplication) { 
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits. 

    let content = UNMutableNotificationContent() 
    content.title = NSString.localizedUserNotificationString(forKey: "Hello,", arguments: nil) 
    content.body = NSString.localizedUserNotificationString(forKey: "Some", arguments: nil) 
    content.sound = UNNotificationSound.default() 
    content.badge = NSNumber(value: UIApplication.shared.applicationIconBadgeNumber + 1) 
    content.categoryIdentifier = "com.mahmut.localNotification" 

    let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 60.0, repeats: true) 
    let request = UNNotificationRequest.init(identifier: "60Sec", content: content, trigger: trigger) 

    let center = UNUserNotificationCenter.current() 
    center.add(request) 

}

は、あなた自身の時間を使用することができます...と後で機能であなたが送信するためにタイマー概念を使用することができ、このようにそれを使用してみてください...の代わりに4 60秒ごとに通知されます。

let triggerTime = (Int64(NSEC_PER_SEC) * 4) 
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, triggerTime), dispatch_get_main_queue(), {() -> Void in 
     self.callYourFunction() 
    })
