GMSMarker infoWindow not updating

Question

我正在使用谷歌地图，它是标记。为了在标记上显示信息，我正在使用自定义视图来显示它。但是一旦我初始化它，值就不会更新。
下面是我的代码。

func mapView(_ mapView: GMSMapView!, markerInfoWindow marker: GMSMarker) -> UIView? {
let location = CLLocation(latitude: marker.position.latitude, longitude: marker.position.longitude
var markerView : MarkerInfoView = Bundle.main.loadNibNamed("MarkerInfoView", owner: self, options: nil)![0] as! MarkerInfoView
let geoCoder = CLGeocoder()
geoCoder.reverseGeocodeLocation(location) { (placemarkers, error) in
if let placemarker = placemarkers?.last {
var strAddress = ""
if let str = placemarker.name {
strAddress += str
}
if let str = placemarker.subAdministrativeArea {
strAddress += ", " + str
}
print(strAddress)
markerView.deviceInfo.text = "HELLO TESTING"
print(markerView.deviceInfo.text!) // This is printing "HELLO TESTING", but not updating on marker
markerView.addressInfo.text = strAddress
}
}
if let str = marker.snippet {
markerView.deviceInfo.text = str.components(separatedBy: "|")[0]
//TODO: add time
markerView.dateInfo.text = str.components(separatedBy: "|")[1]
//            markerView.addressInfo.text = ""
}
else {
markerView.deviceInfo.text = ""
markerView.dateInfo.text = ""
//            markerView.addressInfo.text = ""
}
return markerView
}

请指导我如何在信息窗口中更新值。

试试这段代码

// MARKER - GoogleMaps delegate
func mapView(_ mapView: GMSMapView, markerInfoContents marker: GMSMarker) -> UIView? {
print("title (markerTitle)")
var infoView:UIView!
infoView = UIView()
infoView.frame = CGRect(x: 0, y: 0, width: 300, height: 75)
infoView.backgroundColor = .black
let orderIDLbl = UILabel(frame: CGRect(x: 0, y: 0, width: 300, height: 75))
orderIDLbl.text = "markerTitle" //Your title here
orderIDLbl.font = UIFont.systemFont(ofSize: 15)
orderIDLbl.textAlignment = NSTextAlignment.center
orderIDLbl.numberOfLines = 0
orderIDLbl.textColor = .white
infoView.addSubview(orderIDLbl)
return infoView
}
