There are multiple ways to implement a user cancel operation, depending on your design. Probably the easiest way to do it is to put your worker-thread code in a subclass of NSOperation, and call -cancel on it if the user clicks on your Cancel button or does something else that should cancel the operation. You can then check the isCancelled property of the NSOperation in your worker code to determine if the operation is cancelled or not.

A little late for that, don’t you think?
