How to implement a Day/Night Cycle for Mobile Platform

How can I implement a day scene and a night scene on an IOS app? As dynamic lighting is not available for mobile platforms yet, is there a way to make this work?

It doesn’t necessarily be moving on each frame. It can be updated only on event begin’s.

Or it can basically have a number of states like, sunrise, morning, afternoon, sunset, night. And depending on the game time the game can be initialised with one of these states.

Is one of these ways possible?
Or is there any other way that you might suggest?

Thanks for your time:)
