Slow motion in Sprite Kit iOS

Does anyone have any good ideas of how to accomplish a slow motion effect in Sprite Kit for iOS? This would make all nodes including particle nodes move at 1/2 the speed and also make the particles move that 1/2 the speed.

I can think of how to do this manually, but I wanted to get some more ideas before I start implementing.

I believe you can do:

self.physicsWorld.speed = 0.5;

The docs reference:

speed

The rate at which the simulation executes.

@property(nonatomic) CGFloat speed Discussion The default value is 1.0, which means the simulation runs at normal speed. A value other than the default changes the rate at which time passes in the physics simulation. For example, a speed value of 2.0 indicates that time in the physics simulation passes twice as fast as the scene’s simulation time. A value of 0.0 pauses the physics simulation.

Availability Available in iOS 7.0 and later. Declared In SKPhysicsWorld.h

In update method where you calculate movement speed everywhere when calculations are done multiply the movement by some variable, have it be 1 by default. But when you need slow motion set it to 0.5.
