Unfortunately this is not possible.

You cannot dynamically change your icon. Apple uses private APIs to achieve that. You may be able to achieve this with a jailbroken phone, but I've never tried that.

It's not possible. Apple doesn't allow it for 3rd party apps.

Your app icon is read-only and can't be modified at runtime.

Apple always had some cool private APIs which we developers aren't allowed to use in production Apps, the animated App-Icon is one of them. Most of the time it's to save the experience for the user. Imagine every App uses an auto-updating Icon. The battery-life would go down and it would be a mess on the homescreen when everything is moving and blinking.
