To save an image you can use this line of code:

    UIImage *image = [UIImage imageNamed:"someImage.png"];
    UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);

There are also ways to check when the image is done saving, the full documentation can be found here: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIKitFunctionReference/Reference/reference.html

On newer iOS versions, it is required by Apple that in your info.plist you add a usage descriptor for the key Privacy - Photo Library Additions Usage Description. (NSPhotoLibraryAddUsageDescription)
