I use the GCD serial queue approach. On each update from the slider, cancel all operations in the queue and then add a new operation with the latest slider value. However, the NSOperation subclass should NOT check whether it is cancelled once it starts executing. That way, once it starts, it is assured to complete and you will get periodic updates.
