iPhone SDK: Get GPS coordinates from Google Maps

votes

In an iPhone application I'm developing I need to get GPS coordinates to perform some actions based on the values received. Users should have two possibilities of giving the location:

  • automatically from iPhone build-in GPS
  • by finding a specific point on a map (Google Maps)

I know how to user CLLocationManager to get current position coordinates and I know how to add Google Maps using JS API. What I would like to know if how can I get coordinates for a specific point on a map that user clicks. Is that possible with UIWebView or is there any other way of getting the values I need?

I'd suggest using MapKit framework (introduced in SDK 3.0) that uses google maps services. MKMapView and other classes will provide all functionality you want without the need to mess with java-script:

  1. Displaying google maps
  2. Showing and tracking user location
  3. Easy converting between view coordinates and geo coordinates (see convertPoint:toCoordinateFromView: and convertCoordinate:toPointToView: functions)
  4. Creating and showing custom map markers
  5. Reverse geocoding
  6. etc. :)
