How to remove an CAEmitterLayer?

Question

I'm playing with particle system in iOS using CAEmitterLayer (like in this example) but i can't remove the particles when i want.

I'm trying the following code but it doesn't work:

[self.emitterLayer setLifetime:0];
[self.emitterLayer removeFromSuperlayer];
[self.setEmitterLayer:nil];

Any suggestions? Thanks!

Please use this

for (CALayer *layer in _plusButton.layer.sublayers) {
    if (layer.class == [CAEmitterLayer class]) {
        [layer removeFromSuperlayer];
    }

}
