how to add particles using SpriteKit in iOS7

Question

I'd like to add a particle to my SpriteKit app, but I can't find how to do it. I'm able to create using the particle editor, but how do I add them to my view?

Thanks a lot in advance!

Lets say that you have a particle already created called MyParticle.sks.

First, you have to create a SKEmitterNode with your particle:

NSString *myParticlePath = [[NSBundle mainBundle] pathForResource:@"MyParticle" ofType:@"sks"];
SKEmitterNode *myParticle = [NSKeyedUnarchiver unarchiveObjectWithFile:myParticlePath];

Now that the node is created, you can edit some parameters if you want:

    myParticle.particlePosition = CGPointMake(100, 100);
    myParticle.particleBirthRate = 5;

And the add it to your scene:

[self addChild:myParticle];

This has to be added to your SKScene

I gave this a try, but I keep running into an error " No Visible @interface for 'ViewController' declares the selector 'addChild:' " any tips? – Allister

You should add this to an SKScene, not to a UIViewController. – Padishah
