How do you get a UIImage's geographic coordinates?

Question

How can I get the GPS coordinates of a UIImage after the picture was taken in a UIImagePickerController? Does the image contain the coordinates in it's metadata or should I create a class for the image and its coordinates and save that? Thank you.

Answer 2

Actually, you can access the metadata of an image right after you take the picture. The protocol method that is called by the system after an image has been selected is,

(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

The NSDictionary argument, info, contains a key: UIImagePickerControllerMediaMetadata

AFAIK, You will need CLLocationManager to get the current location and geotag it.

From iOS 8 onwards you can use Photos Framework.

  func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
  let url = info[UIImagePickerControllerReferenceURL] as? URL
        if url != nil {

            let fetchResult = PHAsset.fetchAssets(withALAssetURLs: [url!], options: nil)
            let asset = fetchResult.firstObject
            print(asset?.location?.coordinate.latitude)
            print(asset?.creationDate)
        }
}
