How we can send the location messages using firebase in Swift - ios

Question

I want to send the location messages using firebase. like when user click on button it shows alert which message you want to send like audio,video,location.When user select the location from the given option it will call locationViewController and store the location in firebase.I've simple loaded the google map with marker pin point and defined the coordinates it's self not dynamically. InputActionSheet func that defined in chatViewController when user tap on choose button this function call and inside another function call that will call the functionality of location messages.But I'm confused how we get get coordinates dynamically when user taped on any location on google map and also it will show the marker when user tap.
SimpleViewController class for checking the functionality of google map it's working fine:
class ViewController: UIViewController {
#IBOutlet weak var mapView: GMSMapView!
let manager = CLLocationManager()
let karachi = CLLocationCoordinate2D(latitude: 24.882752, longitude: 67.149848)
let tandoAdam = CLLocationCoordinate2D(latitude: 25.76284, longitude: 68.66087)
override func viewDidLoad() {
super.viewDidLoad()
self.setupMap(title: "Karachi", subtitle: "Shah Faisal", karachi)
self.setupMap(title: "TDM", subtitle: "AK H", tandoAdam)
self.mapView.mapStyle(name:"darkTheme", type:"json")
}
func setupMap(title:String,subtitle:String,_ coordinate:CLLocationCoordinate2D){
manager.delegate = self
manager.requestWhenInUseAuthorization()
manager.startUpdatingLocation()
let camera = GMSCameraPosition.camera(withLatitude: coordinate.latitude, longitude: coordinate.longitude, zoom: 6.0)
mapView.camera = camera
mapView.camera = camera
self.addMarker(title: title, subtitle: subtitle, coordinate:coordinate)
}
func addMarker(title:String,subtitle:String,coordinate:CLLocationCoordinate2D){
let marker = GMSMarker()
marker.icon = #imageLiteral(resourceName: "DiceFive")
marker.position = coordinate
marker.title = title
marker.snippet = subtitle
marker.map = mapView
}
}
extension UIViewController : CLLocationManagerDelegate {
public func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard locations.first != nil else{
return
}
}
}
presentInputActionSheet func in Chat class:
private func presentInputActionSheet() {
let actionSheet = UIAlertController(title: "Attach Media",
message: "What would you like to attach?",
preferredStyle: .actionSheet)
actionSheet.addAction(UIAlertAction(title: "Photo", style: .default, handler: { [weak self] _ in
self?.presentPhotoInputActionsheet()
}))
actionSheet.addAction(UIAlertAction(title: "Video", style: .default, handler: { [weak self] _ in
self?.presentVideoInputActionsheet()
}))
actionSheet.addAction(UIAlertAction(title: "Audio", style: .default, handler: { _ in
}))
actionSheet.addAction(UIAlertAction(title: "Location", style: .default, handler: { [weak self] _ in
self?.presentLocationPicker()
}))
actionSheet.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
present(actionSheet, animated: true)
}
presentLocationPicker func in Chat class:
private func presentLocationPicker() {
let vc = ViewController(coordinates: nil)
vc.title = "Pick Location"
vc.navigationItem.largeTitleDisplayMode = .never
let location = Location(location: CLLocation(latitude: latitude, longitude: longitude),
size: .zero)
let message = Message(sender: selfSender,messageId: messageId,sentDate: Date(),kind: .location(location))
DatabaseManager.shared.sendMessage(to: conversationId, otherUserEmail: strongSelf.otherUserEmail, name: name, newMessage: message, completion: { success in
if success {
print("sent location message")
}
else {
print("failed to send location message")
}
})
}
navigationController?.pushViewController(vc, animated: true)
}

Answer 1

try this
let message = Message(sender: selfSender,messageId: messageId,sentDate: Date(),kind: .location(location))
DatabaseManager.shared.sendMessage(to: conversationId, otherUserEmail: strongSelf.otherUserEmail, name: name, newMessage: message, completion: { success in
if success {
print("sent location message")
}
else {
print("failed to send location message")
}
navigationController?.pushViewController(vc, animated: true)
})
}
