Freeze particle effect in Sprite Kit iOS

Question

Is there a way to freeze a particle node in Sprite Kit for iOS? Basically freeze each of the particles in the particle node exactly where they are.

Answer 1

To pause the particle node:

particle.paused = YES;

Answer 2

particle.paused = YES;

This is also useful in order to speed up performance when an emitter is offscreen and doesn't need to be emitting particles.
