自定义markerInfoWindow在Google地图上显示后会禁用触摸功能

Question

我正在使用GoogleMaps 2.0.1我必须在其tap上显示自定义弹出窗口或自定义标记窗口。它应如下所示：

这是我的自定义标记类的样子：

import UIKit

class MapPopUp: UIView {

    @IBOutlet weak var lblName : UILabel!
    @IBOutlet weak var lblDesc : UILabel!
    @IBOutlet weak var btnClose : UIButton!
    override init(frame: CGRect) {
        super.init(frame: frame)

        var nibContents = NSBundle.mainBundle().loadNibNamed("MapPopUp", owner: self, options: nil)
        self.addSubview(nibContents[0] as! UIView)

    }
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override func didMoveToSuperview() {
        guard superview != nil else {
            return
        }
        self.superview!.autoresizesSubviews = false
    }
}

这些是我的谷歌地图代表

 func mapView(mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {

        let vc =  MapPopUp(frame: CGRectMake(0, 0, 310, 70))
        vc.lblName.text = "N/A"
        vc.lblDesc.text = "N/A"

        vc.btnClose.addTarget(self,action:#selector(MapVC.closeAction(_:)),
                         forControlEvents:.TouchUpInside)


        if let dict = marker.userData as? NSDictionary
        {
            if let strName = dict.objectForKey("name") as? String
            {
               vc.lblName.text = strName
            }
            if let strDesc = dict.objectForKey("description") as? String
            {
               vc.lblDesc.text = strDesc
            }
        }
        vc.layoutIfNeeded()
        vc.layoutSubviews()
        return vc
   }


    func mapView(mapView: GMSMapView, didTapMarker marker: GMSMarker) -> Bool {

     var point = mapView.projection.pointForCoordinate(marker.position)
     point.x = point.x + 100



     let vancouverCam = GMSCameraUpdate.setTarget(marker.position)
        mapView.animateWithCameraUpdate(vancouverCam)
    self.mapView.selectedMarker = marker
        return true
    }

func mapView(mapView: GMSMapView, didTapInfoWindowOfMarker marker:    GMSMarker)
     {
        self.mapView.selectedMarker = nil

     }

Isuue在点击标记后，它显示正确的标记信息窗口，但在谷歌地图卡住后，它没有再次隐藏标记信息窗口。

先谢谢!!
