CAMediaTimingFunction

Basically I want to make a dots animation view like this.


So I look into the CAMediaTimingFunction and it's a bezier function.

https://en.wikipedia.org/wiki/B%C3%A9zier_curve

There is a website that you can view your bezier curve in CAMediaTimingFunction

http://netcetera.org/camtf-playground.html

So I just create 3 dots with different CAMediaTimingFunction that changes alpha like this.




But eventually it don't really have to use CAMediaTimingFunction to approach this. Just create animation groups will be more precise.
