How to set the location for the captured photo by using UIImagePickerController?

Question

I would like to see my captured picture by using UIImagePickerController in Photos app with the geo tagging (Where the picture has taken).

While capturing a snap by using UIImagePickerController , I would like to tag the current location for the captured picture, such that when it get saved to PhotoLibrary , it should show on the map in the Photos (Standard app to show the photos/videos) app. Could anyone has any idea, how the Photos app internal mechanism to show the photos/videos on the map.

Unfortunately the location data requires a bit of work to find.

The delegate method

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

will give you an info dictionary, containing some metadata for the image. This blog has a nice log dump of the typical content:

Based on the full path to the image (found in the info dictionary), you can however dig up the lat and long using ALAssetsLibrary
