Gravity with UIview

Question

I drew a circle in UIView with a help of UIBezierPath . Then I added gravity behavior to that view using UIGravityBehavior and collision behavior using UICollisionBehavior . When the circle collides with other objects this view bumps as square, but I want to work with this view in collisions as with a circle. How can I do it?

Answer 1

You can't use UIKit Dynamics to simulate a circle. It works with rectangular bodies only. You can add collision paths, but I think that is only for the reference frame. I recommend looking at SpriteKit's SKPhysicsBody . Unfortunately, I haven't used it, so I can't provide a code sample.
