ios - 如何在 10 毫秒的时间间隔内将纬度和经度附加到字典数组中？

Question

我正在制作一个应用程序，我必须每隔 10 毫秒发送一次字典的纬度和经度数组。我是这样做的。

   func locationManager(_ manager: CLLocationManager,
                                 didUpdateLocations locations: [CLLocation]) {

    myLocation = locations.last
    let locValue:CLLocationCoordinate2D = manager.location!.coordinate

    currentSpeed = (manager.location?.speed)! as Double
    lat = locValue.latitude  as Double
    lng = locValue.longitude as Double

    var arrayDict = [[String : AnyObject]]
    arrayDict.append["lat":lat , "long" : long]

  }

但是这里我有所有的纬度和经度，我只想在 10 毫秒的时间间隔内附加元素。 提前致谢。

取一个全局命名为“locationBool”的 bool 值

 var locationBool = Bool()
 var arrayDict = [[String : AnyObject]]
override func viewDidLoad()
{
    super.viewDidLoad()

    var timer = Timer.scheduledTimer(timeInterval: 0.10, target: self, selector: #selector(self.update), userInfo: nil, repeats: true);
}
func update() {
// Something code
   locationBool = false
}
 func locationManager(_ manager: CLLocationManager,
                                         didUpdateLocations locations: [CLLocation]) 
    {
        if locationBool == false
        {  
                 locationBool = true
                 myLocation = locations.last
                 let locValue:CLLocationCoordinate2D = manager.location!.coordinate

                 currentSpeed = (manager.location?.speed)! as Double
                 lat = locValue.latitude  as Double
                 lng = locValue.longitude as Double


                 arrayDict.append["lat":lat , "long" : long]
                }
            }
