How do you Reuse custom animation for multiple layers

Question

Hi,

I am a self taught noob with a real interest in code. Please excuse any wrong terminology

I have multiple animation blocks that I want to reuse through out my app, in mulitple views and multiple layers/buttons.

So how do I do the following:

1. Create an "animation class" that all my views can access.
2. Adjust my code so any layer can use it.(see my example code) As you can see this animation is for a specific layer.

Thank you!
