Question

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

在func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool方法中，我尝试禁用自动中心地图，当我选择标记并返回仅显示标记但未启用自动中心的旧行为时。问题是，当我实现该行为（被注释的行）时，标记不会出现，我搜索的所有堆栈溢出都会实现这些行。我迷失了

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代表：

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

    return false
}

GoogleMaps旧的行为，当我点击标记时
