Introducing 10th version of iOS, Apple gave developers a new tool – UIViewPropertyAnimator. It enhances options of creating animation in our application. New options include stopping animation and resuming it (also with other time parameters), finishing animation at any time, reversing animation or moving it to any chosen moment, and many more. Another novelty is the fact that apart from previously used timing options of animation, such as EaseInEaseOut we now also have the ability to define our own time function based on checkpoints of cubic function.
