How do i enabled a Google Maps button in a cell? - ios

Question

In a custom tableViewCell , I connect a View which is a google map class to the custom class
However it seems that these line of code doesn't run in the custom cell that I created
This cell is part of a tableView, I tried to instantiate this cell for example var gmapsCell = GMapTableViewCell in the viewDidLoad of the TableView but it seems it will always returns nil
So I change my approach to below codes
import UIKit
import GoogleMaps
class GMapTableViewCell: UITableViewCell, GMSMapViewDelegate {
let locationManager = CLLocationManager()
#IBOutlet var mapView: GMSMapView!
override func awakeFromNib() {
super.awakeFromNib()
locationManager.requestAlwaysAuthorization()
// For use in foreground
locationManager.requestWhenInUseAuthorization()
mapView.delegate = self
mapView.settings.myLocationButton = true
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
extension GMapTableViewCell: CLLocationManagerDelegate {
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == .AuthorizedWhenInUse {
locationManager.startUpdatingLocation()
mapView.myLocationEnabled = true
mapView.settings.myLocationButton = true
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
if let location = locations.first {
mapView.camera = GMSCameraPosition(target: location.coordinate, zoom: 15, bearing: 0, viewingAngle: 0)
locationManager.stopUpdatingLocation()
}
}
}
The problem right now is that
override func awakeFromNib() {
super.awakeFromNib()
locationManager.requestAlwaysAuthorization()
// For use in foreground
locationManager.requestWhenInUseAuthorization()
mapView.delegate = self
mapView.settings.myLocationButton = true
}
This will never run. My goal is simply to get to the device's current location. Are there any equivalent of viewDidLoad for custom cell?

Answer 1

You need to add "NSLocationWhenInUseUsageDescription" key as a string type in info.plist for the location Manager to start updating locations.

Answer 2

All that code inside awakeNib() should be written in tableView:cellForRowAtIndexPath.
Set all the delegates there.
It will work fine then.
