To close out this discussion in case anyone runs across it in the future trying
to debug the same thing. I had multiple errors, but the final one was that I
had registered to be notified when my NSInvocationOperation finished.
[myOp addObserver:self forKeyPath:@"isFinished"
options:NSKeyValueObservingOptionNew context:NULL];
And then in my method
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object
change:(NSDictionary *)change context:(void *)context
I closed a window that had an NSProgressIndicator. The problem is that the
method is actually called not on the main thread (I think it was the thread
created to process my NSInvocationOperation). Closing these GUI objects from
this other thread seemed to be the final problem generating the warning above.
I moved the code to another method, -finishedReadingAuditFile, and then created
another NSInvocationOperation to call it on the main thread
NSInvocationOperation *tmpOperation;
tmpOperation = [[NSInvocationOperation alloc] initWithTarget:self
selector:@selector(finishedReadingAuditFile) object:nil];
[[NSOperationQueue mainQueue] addOperation:tmpOperation];
And the run-time warning went away.
