Question

我注意到了：

func mapView(mapView: GMSMapView!, didTapAtCoordinate coordinate: CLLocationCoordinate2D) {
    print("You tapped at \(coordinate.latitude), \(coordinate.longitude)")
}

正在覆盖手势识别器：

@IBOutlet weak var mapView: GMSMapView!
let aSelector : Selector = "tappedOnMap"
let tapGesture = UITapGestureRecognizer(target: self, action: aSelector)
mapView.userInteractionEnabled = true
tapGesture.numberOfTapsRequired = 1
mapView.addGestureRecognizer(tapGesture)

func tappedOnMap() {
    print("Tapped")
}

“Tapped”永远不会打印，但是“你这么做”就是这样。

我的地图视图已展开以填充视图屏幕。似乎didTapAtCoordinate覆盖了GestureRecognizer。（我确信这是因为当我将手势识别器附加到该控制器的超级视图（最顶层视图）并在mapView上禁用“用户交互”时，“Tapped”会被打印。）如何调用这两种方法？

这是一个工作班，用来比较您做错了什么：

可能是：

未调用GMSMapViewDelegate
MapView.delegate =未设置自我

在func mapView(**_** MapView: GMSMapView, didTap marker: GMSMarker) -> Bool

前缺少下划线

class CustomMapPicker: UIViewController, GMSMapViewDelegate
{
    @IBOutlet weak var MapView: GMSMapView!

override func viewDidLoad()
{
    super.viewDidLoad()
    MapView.delegate = self
    let camera = GMSCameraPosition.camera(withLatitude: 25.2048, longitude: 55.2708, zoom: 10)
    MapView?.camera = camera
    MapView?.animate(to: camera)
    MapView?.isMyLocationEnabled = false
}

func mapView(_ MapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D)
{
    print("lat = " + "\(coordinate.latitude)" + " long = " +  "\(coordinate.longitude)")
}

func mapView(_ MapView: GMSMapView, didTap marker: GMSMarker) -> Bool
{
    return true
}
}

将google maps的didTapAtCoordinate方法与UITapGestureRecognizer结合使用
