<p>I would like to know the code to save an image to the camera roll on an iPad. 
I am making an app for iPad wallpapers and am not sure how to do this part of my coding. </p>

<p>Im looking to make it so that when you tap a button, an image in the resources is saved to the camera roll. And an alert view tells you the image has been saved.</p>

<p>All help really appreciated! </p>
