Constantly change the direction of gravity to be where an object is randomly moving

Question

I have an object that is randomly moving, and other objects are spawning next to it.

How can I change the gravity direction of the objects that are being spawned to make it so the spawned objects are always moving towards my randomly moving object?

In my didMoveToView I tried adding the following:

self.physicsWorld.gravity = CGVectorMake(costantlyMovingObject.position.x, constantlyMovingObject.position.y)

But this just causes the spawned objects to fly around like crazy

如果要将所有对象移向您的对象，则应使用SKFieldNode radialGravityField 。
