ios - 当我点击标记时，Google map 的旧行为

Question

我使用的是 xcode 9.0、GoogleMaps SDK 2.5.0 和 GooglePlaces 2.5.0。

在方法中 func mapView(_ mapView: GMSMapView, didTap mark: GMSMarker) -> Bool 当我选择一个标记并返回到仅显示标记且不启用自动居中的旧行为。问题是，当我实现该行为(注释的行)时，标记不会出现，我搜索的所有堆栈溢出都实现了这些行。我迷路了

class MapViewController: UIViewController, GMSMapViewDelegate
{

    //MARK: Class Life Cycle

    @IBOutlet weak var mapView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        setupUI()
        setupMap()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    //MARK: -Setup

    func setupUI() {
        navigationController?.hideBar()
    }

    func setupMap() {
        let map = MapManager.sharedInstance.setupMap(view: mapView, latitude: GoogleMap.latitude, longitude: GoogleMap.longitude, zoom: GoogleMap.zoom)
        map.delegate = self
        mapView.addSubview(map)

        MapManager.sharedInstance.setupMapMarkers(map: map, file: File.geoFence, fileType: File.json)
    }

    func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
        //        mapView.selectedMarker = marker
        //        return true

        return false
    }
}

如果有人遇到这个奇怪的错误，奇怪的解决方案是再次添加委托(delegate):

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
    mapView.delegate = self
    mapView.selectedMarker = marker
    return true

    return false
}
