UNLocationNotificationTrigger-不在模拟器中工作
使用iOS 10中提供的用户通知框架,我尝试在用户使用UNLocationNotificationTrigger输入特定地理位置时触发通知。 当我通过模拟Geo位置尝试通过模拟器进行测试时,通知不会被触发,但位置管理器会返回更新的地理位置。 这应该在真实设备中测试而不是在模拟器中运行吗?
根据Apple文档 :
应用必须请求访问位置服务,并且必须具有使用此类的使用时权限。 要请求使用位置服务的权限,请在调度任何基于位置的触发器之前调用CLLocationManager的requestWhenInUseAuthorization()方法。
但是,如果我的模拟器/设备“使用中”权限不够,则必须将权限设置为“始终”。
因此,将此密钥添加到pinfo.list中
NSLocationAlwaysUsageDescription We use your location to warn you when there are adorable cats nearby
然后激活位置。 只有在您确定始终获得授权后才能定义触发器,例如我在didChangeAuthorizationStatus中执行此操作:
class myClass : CLLocationManagerDelegate { var locationManager: CLLocationManager() func init() { // Note: defining the location manager locally in this function won't work // var locationManager: CLLocationManager() // as it gets gargabe collected too early. locationManager.delegate = self locationManager.requestAlwaysAuthorization() UNUserNotificationCenter.current().delegate = self UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound]) {(accepted, error) in if !accepted { logger.info("Notification access denied.") } } // MARK CLLocationManagerDelegate: func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) { if status == .AuthorizedAlways { let region = CLCircularRegion(center: CLLocationCoordinate2D(latitude: 61.446812, longitude: 23.859914), radius: 1000, identifier: "test") logger.info("Notification will trigger at \(region)") region.notifyOnEntry = true region.notifyOnExit = false let trigger = UNLocationNotificationTrigger(region: region, repeats:true) let content = UNMutableNotificationContent() content.title = "Oh Dear !" content.body = "It's working!" content.sound = UNNotificationSound.default() let request = UNNotificationRequest(identifier: "textNotification", content: content, trigger: trigger) UNUserNotificationCenter.current().removeAllPendingNotificationRequests() UNUserNotificationCenter.current().add(request) {(error) in if let error = error { print("Uh oh! We had an error: \(error)") } } } } }
