KVO, which thread?


  • Subject: KVO, which thread?
  • From: Todd Heberlein <email@hidden>

I have an NSInvocationOperation, anOp, and register to observe when its isFinished variable is set

[anOp addObserver:self forKeyPath:@"isFinished" options:NSKeyValueObservingOptionNew context:NULL];

When my operation is done, isFinished is set, and thus my method -observeValueForKeyPath:ofObject:change:context: is called, which thread is it being called on? The main thread, or the thread created to process the NSInvocationOperation?

Thanks,

Todd
