Transferring Data from Firebase into Custom Info Window - swift

Question

So I'm trying to transfer the data I've snapshotted from firebase into the custom info window. I currently have four different categories of activities and as such there are four different marker arrays and functions. I have one generic custom info window that I wish to display the markers Title, rating and difficulty level into.
I am having an issue Ive currently tried appending all data into one structured array and then calling the data from that array but all I get is the same set of data in all the info windows. I want each info window to specifically display the data associated with that GMS Marker.
This is is the function that shows the board activities. I have four of these functions for each activity.
func showBoardIcon() {
ref = Database.database().reference()
ref.child("location").observe(.childAdded) { (snapshot:DataSnapshot) in
if let dict = snapshot.value as? [String:AnyObject] {
if dict["Activity"] as! String == "Board" {
let longitude = dict["Longitude"] as! String
let lattitude = dict["Lattitude"] as! String
let title = dict["Title"] as! String
let key = dict["id"] as! String
self.boardIconArray.insert(coordinate(title: title, carLat: lattitude, carLng: longitude, idKey: key), at: 0)
let n = self.boardIconArray.count
let heightWidth = (self.mapView.frame.height / 12)
for var Marker in 1...n {
let boardMarker = GMSMarker()
let boardIconView = UIImage(named: "boardPin")
let image = boardIconView
let location = CLLocationCoordinate2D(latitude: Double(lattitude)!, longitude: Double(longitude)!)
boardMarker.position = location
boardMarker.icon = image
boardMarker.title = title
boardMarker.icon = self.image(image!, scaledToSize: CGSize(width: heightWidth, height: heightWidth))
func displayBoard() {
if self.boardNumber == "1" {
boardMarker.map = self.mapView
self.arrBoardMarker.append(boardMarker)
} else {
boardMarker.map = nil
}
}
displayBoard()
break
}
}
}
}
}
This is the function that displays the custom info window.
func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {
let Markerview: infoWindow = UIView.fromNib()
let a = arrCarMarkers.count
let b = arrLegMarker.count
let c = arrWaterMarker.count
let d = arrBoardMarker.count
let all = 0 + a + b + d + c
Markerview.titleLbl.text = arrAllMarkers[key].title
Markerview.ratingLbl.text = ("\(arrAllMarkers[all].rating)/5")
Markerview.difficultyLbl.text = arrAllMarkers[all].diff
Markerview.idKey.text = arrAllMarkers[all].key
transferKey = arrAllMarkers[all].key
Markerview.alpha = 0.8
Markerview.layer.cornerRadius = 30
return Markerview
}
Im not sure if what Im doing is even correct. Like I said I just want the data being snapshotted for each marker to be shown to that specific marker.

Answer 1

So I Managed to solve the issue.
I added
boardMarker.title = key
inside the loop where the Marker is being created.
I then wrote this section of code
func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {
let markerTitle = marker.title as! String
let Markerview: infoWindow = UIView.fromNib()
filteredStruct = arrAllMarkers.filter{$0.key.range(of: markerTitle) != nil}
print(filteredStruct)
Markerview.titleLbl.text = filteredStruct[0].title
Markerview.ratingLbl.text = filteredStruct[0].rating
Markerview.difficultyLbl.text = filteredStruct[0].diff
transferKey = markerTitle
Markerview.alpha = 0.8
Markerview.layer.cornerRadius = 30
print(transferKey)
return Markerview
}
and it works perfectly!
