iOS 7 CAEmitterLayer spawning particles inappropriately

Question

Strange issue I can\'t seem to resolve where on iOS 7 only, CAEmitterLayer will spawn particles on the screen incorrectly when birth rate is initia

Answer 1

For me, the issue with my CAEmitterLayer, when moving to iOS7 was the following:

In iOS7 setting the CAEmitterLayerCell's duration resulted in the particle not showing at all!

The only thing I had to change was remove the cell.duration = XXX and then my particles began showing up again. I am going to eat an Apple over this unexpected, unexplained hassle.
