Question

我有一个GMSMapView实例orderMapView，该实例链接到我的UIViewController。我授予了位置许可权，后来成为orderMapView

的代表

orderMapView.delegate = self

我也使该类符合GMSMapViewDelegate。然后，我在viewDidLoad中启动多个标记，其中之一是这样的：

let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: CLLocationDegrees(dataLat), longitude: CLLocationDegrees(dataLng))
marker.title = dataName
marker.snippet = "LAT: \(dataLat), LONG: \(dataLng)"
marker.appearAnimation = .pop
marker.map = orderMapView
marker.isDraggable = true
marker.isTappable = true

我还实现了以下委托方法：

func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D){
//1 - IT NEITHER COMES HERE
    print(coordinate)
}

func mapView(_ mapView: GMSMapView, idleAt position: GMSCameraPosition) {
    print(position)
}


func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
//2 - IT NEITHER COMES HERE
    orderMapView.selectedMarker = marker
    return true
}

func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {
    let view = UIView(frame: CGRect.init(x: 0, y: 0, width: 200, height: 70))
    view.backgroundColor = UIColor.white
    view.layer.cornerRadius = 6

    let lbl1 = UILabel(frame: CGRect.init(x: 8, y: 8, width: view.frame.size.width - 16, height: 15))
    lbl1.text = marker.title
    view.addSubview(lbl1)

    let lbl2 = UILabel(frame: CGRect.init(x: lbl1.frame.origin.x, y: lbl1.frame.origin.y + lbl1.frame.size.height + 3, width: view.frame.size.width - 16, height: 15))
    lbl2.text = marker.snippet
    lbl2.font = UIFont.systemFont(ofSize: 14, weight: .light)
    view.addSubview(lbl2)

    return view
}

我可以在地图上看到标记，但是当我点击它时，地图会缩小，并且永远不会在这些标记上显示信息窗口。请帮忙。

更新：这是在模拟器上发生的，因为我没有设备。那会是唯一的酸痛问题吗？
