Hi,
I'm running into some trouble with NSOperation / NSOperationQueue.
In order to tear down everything gracefully, I use something like
[queue cancelAllOperations];
[queue waitUntilAllOperationsAreFinished];
My NSOperation subclasses just have a straightforward -(void) main
method.
It works as advertised for me unless I'm trying to cancel the
operations.
Regular run:
(MyOperation) change of isExecuting to 1
(MyOperation) change of isExecuting to 0
(MyOperation) change of isFinished to 1
Cancel run:
(MyOperation) change of isExecuting to 1
** Cancel...
(MyOperation) change of isCancelled to 1
My op polls isCancelled, returns from main and nothing more happens.
op.isFinished and op.isExecuting is not updated, bringing
waitUntilAllOperationsAreFinished and other KVC observers to an halt.
Do I really need to reimplement the whole state (isFinished,
isExecuting) logic just in order to support cancellation?
TIA,
Tom_E
