If you mean “cancel” in the sense of “prevent it from starting”, then the answer is yes, you can use “dispatch_block_cancel”: The original GCD didn’t have this ability, but it was added a few years ago. You can’t cancel it once it’s started running, except by means of setting a flag as you mentioned earlier.
