I’m using NSOperationQueue, and NSOperation for running some function on background click.
But I want to be able, when user clicks some button, stop that Operation.

How can I do it?

Something like, [currentoperation stop];
Cancel – won’t work me. I want to stop immediately.

Thanks

    You should be calling the -cancel method, and the operation itself has to support being cancelled by monitoring the isCancelled property/keypath and safely stopping when its value becomes YES. If the NSOperation is your own, you will probably have to create a custom subclass to implement this functionality. You cannot (safely) force an arbitrary operation to immediately stop. It has to support being cancelled.
