Is it UIDynamic or just UIBezierpath?

Question

Objective-C

Hello, with the help of Bezier curves I want to implement such a thing ( it must be animated ), that is, when the central point (and reference points) appears, it takes the maximum position, then the amplitude is damped.
So the question is, is this implemented through UIDynamic?
Experienced comrades, help, for the third day I have been racking my brains, it’s not an option to make just a rectangle, I already wanted to.
