Sprite Colliding With Screen Bottom?

My scene has a [SKPhysicsBody bodyWithEdgeLoopFromRect: self.frame]. How can I make an action when a sprite collide only with the bottom of the screen?

So, create a body that represents only the bottom of the screen with `SKPhysicsBody's bodyWithEdgeFromPoint:toPoint: message. Something like:

const int buffer = 100;
SKPhysicsBody *myBody = [bodyWithEdgeFromPoint:CGPointMake(-buffer, screenHeight) toPoint:CGPointMake(screenWidth + buffer, screenHeight)];

Notice the buffer to prevent things from falling off the "edge" until they're off the screen entirely (alter the constant to fit your use case).
