Can I slow down or stop physics in SpriteKit?

Question

It seems to me that a framework that aims for simplicity would have that method so, and not to remove every node from the physics accounting like I'm doing now:

[self enumerateChildNodesWithName:@"live" usingBlock:^(SKNode *node, BOOL *stop){
        [node removeFromParent];
}];

I'm sorry if this is a noob question, I've just started working with SpriteKit. Thanks!

Answer 1

It has "that method". If you look in the SKPhysicsWorld reference you'll find the speed property. Speed = 0 means paused.
