Save A UIImage Outside Of The Photo Album
In an earlier post I pointed out a tutorial on how to save pictures taken with the camera to a photo album.
John Muchow has written a new tutorial this time showing how to save PNG or JPG images to the documents directory.
This is done by using the UIImageJPEGRepresentation or UIImagePNGRepresentation functions to save the images, and writing to the documents directory.
The full code snippet can be found here: Save UIImage Object As A PNG or JPEG File
