iOS: saving UIImageView to Camera Roll

Question

Even though this sounds super simple, I got stuck on this because of how my app works.

I have a UIImageView that loads an online image. On the app, I will have a button that gives the user a choice to export the image to Camera Roll.

Most solutions such as UIImageWriteToSavedPhotosAlbum don't work with UIImageView.

Should I first capture a UIImage from the UIImageView and then save to Camera Roll? How? Or can I save directly?

Yes, you need to save the `UIImage`, not `UIImageView`. – rmaddy Jul 19 '16 at 04:25 — rmaddy, Jul 19 '16 at 04:25

The UIImage is a representation of an image. UIImageView is a container for displaying that image in your app. What you need to save is the image, not the container.
