Using UIImagePickerController to get image — how to know whether to save PNG or JPEG?

Question

I\'ve got a UIImagePickerController letting the user pick an image out of the image library, and am getting its results via the didFinishPickingMediaWithI

Answer 1

in the dictionary the key UIImagePickerControllerReferenceURL will give you informations about the type

(gdb) po info

{
    UIImagePickerControllerMediaType = "public.image";
    UIImagePickerControllerOriginalImage = "";
    UIImagePickerControllerReferenceURL = "assets-library://asset/asset.JPG?id=EFC44C3C-9C82-4669-924B-A2B9DE6F1F45&ext=JPG";
}

In this case it is a jpg as shown by ext=JPG
