How do I get the coordinates of the IOS device using RubyMotion?

Question

Just looking for the simplest example of extracting the gps coordinates - not looking to render them on a map or anything.

Thanks,

For iOS 8, do the following:

1. Add these lines to your Rakefile:

   app.frameworks += ['CoreLocation']
   app.info_plist['NSLocationWhenInUseUsageDescription'] = 'I need it'
   app.info_plist['NSLocationAlwaysUsageDescription'] = 'I always need it'
   

2. In viewDidLoad in your ViewController add:

   @locationManager = CLLocationManager.alloc.init
   @locationManager.requestWhenInUseAuthorization
   @locationManager.delegate = self
   @locationManager.startUpdatingLocation
   

3. Implement locationManager:didUpdateLocations:

   def locationManager(manager, didUpdateLocations:locations)
     coordinate = locations[0].coordinate
     puts "lat #{coordinate.latitude}, long #{coordinate.longitude}"
   end
   

4. If you need just the current location once, then call:

   manager.stopUpdatingLocation
   

   after getting the location in didUpdateLocations.
