get URL/Exif of UIImage

[s4lfish]

Hi there,

I've a problem with full path to image file and getting the exif data.

I choose an image with the ImagePickerController, an want to get the path to this image on my iPhone to upload it to an database via multipart upload.
Also i want to read the exif data, and if there is no GPS-Location stored, the user should geotag the image himself using googlemaps.

I've tried many diffrent ways to do this, an nothing works, and i only find old threads which are outdated to the new xCode/iOS version.

So i hope someone here can help me doing this stuff. I'm stuck here for over a week -.-
I'm thankful for every link or code snippet u can show me!

Summarized: After ImagePickerController didFinishPickingMedia:
- Read Exif data
- write GPS data if no GPS tagging in EXIF
- get full path to upload original image

P.S.: Another little problem: I have an class GEOImage : UIImage, where i want to store a description, title etc., but the ImagePickerController returns an UIImage. How do i create an GEOImage from the UIImage given by the ImagePicker?

The creation of the GEOImage is fixed now,
but i still need to get the full path to the image file ... has anyone an idea?
