Am I using NSConditionLock correctly?

Subject: Am I using NSConditionLock correctly?

I am using NSConditionLock to delay the completion of a method while another thread completes. I am not sure that I am using it correctly, since my conditional lock hangs up the program.

In my worker thread I do [calculatingLock lock]; [calculatingLock unlockWithCondition:YES] when calculation starts and [calculatingLock lock]; [calculatingLock unlockWithCondition:NO] when it stops.

In my method that depends on the worker thread stopping I do [calculatingLock lockWhenCondition:NO]; [calculatingLock unlockWithCondition:NO]. The idea is that it should wait for the condition to be set to NO before continuing. It hangs at this point. If this is all correct then my problem lies elsewhere.
