I know how to save an image using standard API calls to the camera roll. I also know that devices without a camera get saved to the Photo Library.
For devices with a camera, how do I save a UIImage to the Photo Library INSTEAD of the camera roll?
The photo library is just a placeholder that shows all the pics on your phone, including the camera roll. So, if you deleted a pic from the camera, it would be gone on the photo library. The one in the photo library is not a duplicate; it’s more like a shortcut. Makes perfect sense. It's like a "favorites" folder. It sources it's info from the main folder.
This is what you find. the link shows how to store the images in iPhone Gallery. Check out the link: http://sugartin.info/2012/01/10/permanently-download-image-and-fetch-locally-images/
