swift - 如何在移动，谷歌 map ，快速移动时将当前位置点保持在 map 中心

在我的项目中，我正在使用Google Map。我启用这样的当前位置点：

 self.mapView?.isMyLocationEnabled = true

之后，我将得到当前位置的纬度和经度，如下所示：

 guard let currentLat = self.mapView?.myLocation?.coordinate.latitude,
          let currentLan = self.mapView?.myLocation?.coordinate.longitude else {
          showMessageFail(title: "Fail", myMessage: "Could not determine your current location")
          return
        }

然后像这样将相机聚焦在当前位置：

  let currentPosition = CLLocationCoordinate2D(latitude: currentLat, longitude: currentLan)
  self.mapView?.animate(toLocation: self.currentPosition)

一切都很好，现在它在地图中心显示了当前位置点（谷歌地图上的蓝色点）。现在，当当前位置发生变化时，假设我在车上，当前位置点就会移动，在某个点上它会移动到地图范围之外。如何始终将当前位置点保留在地图中心，而不移动地图点。任何帮助将非常感激。

最佳答案

currLocation = manager.location！

    let locationOfDevice: CLLocation = currLocation // this determines the location of the device using the users location

    let deviceCoordinate: CLLocationCoordinate2D = locationOfDevice.coordinate // determines the coordinates of the device using the location device variabel which has in it the user location.

    let span = MKCoordinateSpan(latitudeDelta: 1, longitudeDelta: 1) // this determines the span in which its determined that 1 degree is 69 miles.

    let region = MKCoordinateRegion(center: deviceCoordinate, span: span) // set the center equal to the device coordinates and the span equal to the span variable we have created this will give you the region.

    mapView.setRegion(region, animated: true);
