ios - 点击区域时不显示本地通知

Question

我正在开发简单的 To-Do 应用程序，它在 UILocalNotification 中使用 CLRegion 支持的 IOS 8 功能。

这是我用来安排本地通知的代码:

    var schedule = false
    let notification = UILocalNotification()

    /// Schedlue with date
    if let reminder = self.dateReminderInfo {
        schedule = true
        notification.fireDate = reminder.fireDate
        notification.repeatInterval = reminder.repeatInterval
        notification.alertBody = self.title
    }

    /// Schedule with location
    if let reminder = self.locationReminderInfo {
        schedule = true
        let region = CLCircularRegion(circularRegionWithCenter: reminder.place.coordinate, radius: CLLocationDistance(reminder.distance), identifier: taskObjectID)
        region.notifyOnEntry = reminder.onArrive
        region.notifyOnExit = reminder.onArrive
        notification.region = region
        notification.regionTriggersOnce = false
    }

    /// Schedule
    if schedule {
        notification.userInfo = ["objectID": taskObjectID]
        UIApplication.sharedApplication().scheduleLocalNotification(notification)
    }

用日期安排工作。我安排通知，退出应用程序，并在适当的时间在屏幕上显示通知，太棒了。问题是当我安排位置通知时。我以米为单位传递坐标和半径(例如 100 米)。该应用程序未显示任何内容。我在家里测试它，将点放在 1 公里的距离内并到达那里。没有显示通知。我也在玩模拟器，并将位置从可用位置更改为我附近的自定义位置并返回。没有显示通知。问题出在哪里？

在 AppDelegate 中，我正在注册通知:

    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil))

这是定位服务的代码。

func startLocationService() {

    self.locationManager = CLLocationManager()
    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest

    let status = CLLocationManager.authorizationStatus()
    if status == CLAuthorizationStatus.AuthorizedWhenInUse || status == CLAuthorizationStatus.Denied {
        let title = (status == CLAuthorizationStatus.Denied) ? "Location services are off" : "Background location is not enabled"
        let message = "To use background location you must turn on 'Always' in the Location Services Settings"

        let alertController = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.Alert)

        /// Settings
        alertController.addAction(UIAlertAction.normalAction("Settings", handler: { _ in
            UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString)!)
            return
        }))

        /// Cancel
        alertController.addAction(UIAlertAction.cancelAction(String.cancelString(), handler: nil))

        self.presentViewController(alertController, animated: true, completion: nil)
    } else if status == CLAuthorizationStatus.NotDetermined {
        /// nothing
    }

    self.locationManager.requestAlwaysAuthorization()
    self.locationManager.requestWhenInUseAuthorization()

    self.locationManager.startUpdatingLocation()
}

CLLocationManager 正在工作，因为我有经常调用的委托(delegate)方法。

/// Mark: CLLocationManagerDelegate
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    if let location = locations.first as? CLLocation {
        self.navigationItem.title = "\(location.coordinate.latitude)" + " " + "\(location.coordinate.longitude)"
        println(self.navigationItem.title)
    }
}

我正在尝试第二天解决问题，但找不到好的解决方案如何在用户出现或离开时显示本地通知。我不知道使用 UILocalNotification region 属性是否适合此解决方案，或者我应该创建一种机制来搜索我在应用程序中保存的位置并每次位置更改时检查。对此主题的任何评论也表示赞赏；)

提前谢谢你。

我看到你没有注册通知

let settings = UIUserNotificationSettings(forTypes: notificationType, categories: 类别) application.registerUserNotificationSettings(设置)
