Pause SpriteKit physics game SKSpriteNode child

I have an SKSpriteNode with a dynamic physical body on SKNode *_fgLayer .

Now, when I pause or pause the game, I want SKSpriteNode to stay in place and not spin or fall. If I just use _fgLayer.paused = YES; , SKSpriteNode does not remain in place, but rotates and falls. If I set physicsBody.dynamic = NO; when paused and physicsBody.dynamic = YES; When it has been suspended, it will work.

However, after several attempts, I always get the following failure:

"Assertion failed: (typeA == b2_dynamicBody || typeB == b2_dynamicBody), function SolveTOI, file /SourceCache/PhysicsKit/PhysicsKit-4.6/PhysicsKit/Box2D/Dynamics/b2World.cpp, line 670."

So, I suppose setting physicsBody.dynamic = NO; and back does not work.

Does anyone have an idea how to pause dynamic physical bodies in order to stay in place when the game is paused?

Try setting your World.speed physics to 0.0:

 scene.physicsWorld.speed = 0.0

Setting scene.view.paused = YES works for me - especially when there are node actions on the child server.

self.scene.view setPaused:YES
