Google Maps Mapview不在标记上居中

Question

我正在使用Swift 4在ios中使用google maps，我必须在屏幕上显示一个带有标记的mapview，问题是，每当我显示mapview时，我都会得到以下结果：

我想要得到的结果是这样：

这是我使用的代码：

 func loadMap(location:CLLocation){
    self.mapView.isMyLocationEnabled = true
    self.mapView.isUserInteractionEnabled = true
    self.view.layoutIfNeeded()
    self.addLocationMarker()
}

func addLocationMarker(){
    // Creates a marker in the center of the map.
    let marker = GMSMarker()
    print(self.startLocation)
    marker.position = CLLocationCoordinate2D(latitude: self.startLocation.coordinate.latitude, longitude: self.startLocation.coordinate.longitude)
    marker.map = self.mapView

    let camera = GMSCameraPosition.camera(withLatitude: self.startLocation.coordinate.latitude, longitude: self.startLocation.coordinate.longitude, zoom: 12.0)
    self.mapView.camera = camera
}

地图视图是情节提要中视图的出口

此代码对我来说效果很好。试试看（快速4）

func setupMapView() {

    DispatchQueue.main.async {
      let position = CLLocationCoordinate2D(latitude: 32.9483364, longitude: -96.8241543)
      let marker = GMSMarker(position: position)
      self.mapView.camera = GMSCameraPosition(target: position, zoom: 15, bearing: 0, viewingAngle: 0)
      marker.title = "Enter marker title here"
      marker.map = self.mapView
    }  
}
