I have a thread that is invoked with: [NSThread detachNewThreadSelector:@selector(threadMethod:) toTarget:self withObject:self];
It uses NSConditionLock and works well. This thread performs a complex process but does it slowly so as to not use much processor time. I specify how long I want it to take (1 to 30 minutes) and use: // block this task until time has elapsed or an exit signal is received. if ([[self lock] lockWhenCondition:kConditionThreadMustExit beforeDate:[self blockUntil]]) [[self lock] unlock]; blockUntil simply checks to see how much work has been done vs how much time has passed and if 50% of the work has been done, blocks until 50% of the time has passed. It works well since the work is very linear. I would like to move this to NSOperation and NSOperationQueue but I see no way to replicate this behavior. My current thread is limited to a single processor core and with NSOperation I could split it to multiple cores, but in so doing I seem to lose this "delay for a while" bit. Any ideas?
