Question

我从xib文件创建了一个自定义信息窗口，并将其放入此func中：

    func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {
        let infoWindow = Bundle.main.loadNibNamed("InfoWindowMap", owner: self.view, options: nil)!.first! as! InfoWindowMap
        infoWindow.label.text = marker.title // it works but takes information from my marker, but i want take data from, array screenPlaces
        print(screenPlaces.count) =// i want to call an array what i need, but it's empty
        return infoWindow
    }

我的数组screenplaces稍后会在我连接到API时附加：

 if status == "success"{
                for (_,subJson):(String, JSON) in json["data"]["services"] {
                    let id = subJson["id"].intValue
                    let name = subJson["name"].stringValue
                    let icon = subJson["icon"].stringValue
                    let adress = subJson["address"].stringValue
                    let latitude = subJson["latitude"].stringValue
                    let longitude = subJson["longitude"].stringValue
                    self.screenPlaces.append(ScreenData(name:name, id:id,adress:adress,icon:icon, latitude: latitude, longitude: longitude))
                    for i in self.screenPlaces{
                        let position = CLLocationCoordinate2D(latitude: Double (i.latitude)!, longitude: Double( i.longitude)!)
                        let marker = GMSMarker(position: position)
                        marker.map = self.mapView
                        marker.title = (i.name)
                        marker.snippet = (i.adress)
                    }
                }

事实证明，在添加数组之前，我先从数组中调用信息。如果我将函数func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker)放在if status == "success"{}下方，则它不起作用，我看不到al的数组计数。我该如何解决？
